    THOMPSON, Circuit Judge.1     When he was twenty-eight,
    Byron Montijo-Maysonet drove three middle schoolers to a motel so
    he and his pal could have sex with them.       That's called sexual
    assault, see 
    P.R. Laws Ann. tit. 33, § 5191
    (a), and federal
    statutes make it a crime to "entice" or "induce" it over the
    Internet or "transport" a minor within Puerto Rico to commit it.
    See 
    18 U.S.C. §§ 2422
    (b), 2423(a); see United States v. Cotto-
    Flores, No. 18-2013, 
    2020 WL 4582283
    , at *9 (1st Cir. Aug. 10,
    2020).   Montijo now asks us to flip his convictions and sixteen-
    and-a-half-year sentence.    Seeing no reversible error, we affirm.
    HOW THE CASE GOT HERE
    The Two "Vueltas"
    It all started in November 2015, when Montijo's cohort,
    Luis Meléndez (a/k/a "Puky"), met CAP (his cousin's daughter) at
    a family birthday party.2   She had just turned fourteen and started
    eighth grade at Marchand Middle School, a school for seventh to
    ninth graders in Manatí, Puerto Rico.      The two struck up a chat
    and, before they left, exchanged contact info so Meléndez could
    write to CAP on KIK, an instant messaging app.    A few days later,
    1 Judge Torruella concurs in this opinion subject to what he
    stated in his separate opinion in United States v. Cotto-Flores,
    No. 18-2013, 
    2020 WL 4582283
    , at *21–23 (1st Cir. Aug. 10, 2020).
    2 Given Montijo's many sufficiency     challenges, "we rehearse
    the facts in the light most favorable to   the [guilty] verdict," so
    far as the evidence may be reasonably      construed to support it.

    Meléndez messaged CAP and they made plans to meet again, this time
    without her family knowing.    In the meantime, Meléndez found CAP's
    friend DPP on Facebook and looped her into a group chat.     DPP was
    thirteen years old and also in eighth grade.           On a Friday,
    Meléndez, CAP, and DPP used KIK to plan to meet the following
    Monday (November 24, 2015) at the middle school and drive to a
    motel.
    As planned, when they got to school on Monday, CAP and
    DPP walked to a nearby food truck, where Meléndez and Montijo were
    waiting.   They weren't in their school uniforms, Montijo stresses.
    Before that day, neither girl had spoken to Montijo.        Meléndez
    introduced himself to DPP, said Montijo was his "friend," and told
    her they "were going to go for a ride."
    Montijo drove. First, they stopped at a housing project,
    where the men asked the children if they "wanted to smoke or drink
    anything."     Then, Montijo drove to a motel called "El Jackeline,"
    a secluded joint tucked away on a long road off of Route 2 and
    surrounded by a hedge and a concrete wall. The motel didn't charge
    an overnight rate.     Instead, guests could pay twenty dollars to
    use a room for six hours.     To rent a room, you pull into a garage
    next to a cabana, put the money in a drawer, and enter the room.
    An employee looks through a peephole at the gate to see the car's
    license plate number and record the plate number, the room number,
    and the time of arrival — all without seeing the guests.   The motel
    - 3 -
    room itself (at least the one Montijo used) is a 200-square-foot
    unit   with    two   plastic    chairs,       a    bathroom,   and    a    double    bed
    surrounded by mirrors.         The whole set up (the motel's owner later
    testified) is designed to ensure guests' "privacy."
    Once   they    got     there,       things   happened       "fast,"    DPP
    testified.      Montijo and Meléndez rented two cabanas, and Montijo
    pulled the car into a garage next to one of them.                         Meléndez and
    CAP went into one room, and Montijo and DPP went into another.
    Once in the bedroom, Montijo "quickly told me that I didn't have
    to do anything I didn't want to," DPP later recounted.                        They sat
    down on the bed and Montijo told her that "he liked [her] hair,
    [her] eyes."     In the other room, Meléndez had sex with CAP.                      Then,
    CAP and Meléndez called DPP to tell them they'd "finished," and
    they all met back at the car.
    Montijo drove the girls back to the school.                    Once they
    got there, Montijo and Meléndez made sure to stay out of sight.
    Instead of driving DPP and CAP to the school's front door, the men
    dropped them off one street away — according to CAP and DPP, so
    "the   teachers      and    people    from    the    school"   wouldn't       see    the
    defendants.      After that, CAP never spoke to Meléndez or Montijo
    again.
    But over the next week, Montijo used KIK to keep in touch
    with DPP.      At trial, DPP testified that they "didn't talk about
    anything specific.         It was just that [Montijo] wanted to see [her]
    - 4 -
    again."    Soon, another "group [chat] was formed," this time among
    Meléndez, Montijo, and DPP.            "[O]nce [the chat] was opened, the
    first thing" Meléndez said was that DPP should "bring in [an]other
    person."     In context, DPP took this to mean "another girl."                So
    she added her friend KVM to the group chat.           KVM was also thirteen
    and in eighth grade.       With KVM added, Meléndez, Montijo, and DPP
    all said they "wanted to do another outing," meaning another
    "ride."     They used the word "vuelta" in Spanish (the same word
    they'd used before).       And they planned to "meet in the same way"
    as last time:      Montijo and Meléndez would pick the girls up at the
    food truck and drive them back to the motel.
    So, on November 30, 2015 (six days after the first
    outing), Montijo and Meléndez took DPP on another drive, this time
    with KVM.     That morning, after DPP's mother dropped her off at
    school, she and KVM met Montijo and Meléndez at the same food
    truck.      They   were   both    in   school   uniform,   and   DPP   had   her
    schoolbag.    After Meléndez "introduced himself to [KVM]," Montijo
    drove them once more to the housing project, where (once again)
    the men asked the children if they "wanted to drink anything or
    smoke anything."       Then he drove to the same motel.           On the way
    (DPP testified), KVM asked DPP what "she ha[d] to do."                       DPP
    (parroting Montijo) "told her that she didn't have to do anything
    she didn't want to do."          When they arrived at the motel, the four
    paired off like last time — Meléndez with KVM, Montijo with DPP —
    - 5 -
    into separate cabanas.   This time, "when [DPP] got into the cabana
    with [Montijo]," they had sex.
    At that point — in a scene Montijo made the centerpiece
    of his defense — DPP testified that she "took out [her] notebook,"
    and Montijo "saw [her] grade" (which was presumably written on the
    notebook) and "asked [DPP] how old [she] was."    DPP said thirteen.
    Montijo was "shock[ed]" (shocked!), he tells us.    Meléndez and CAP
    had told him she was sixteen and told DPP that Montijo was twenty.
    Montijo told DPP that he was really twenty-eight, and that if he'd
    "known that [she] was [thirteen], he wouldn't have done it."    But
    he assured her he would "wait for [her] to come out of high school"
    and "was going to take care of [her]."
    Montijo and DPP then went to the cabana next door, where
    they saw Meléndez and KVM naked on the bed.       DPP went into the
    room and "took the money . . . that was right next to [Meléndez],"
    which she'd been told to take to Montijo.    Just then, Meléndez's
    phone rang.   DPP answered it.   On the other line, CAP warned that
    the school had noticed they were gone and the police were waiting
    there.   DPP hung up and gave Montijo the news.    Once Meléndez and
    KVM got dressed, the men (with Montijo driving) drove the girls to
    a Burger King for an alibi — "so [they] could say" that they'd
    "been eating."
    After the pit stop, Montijo drove the girls back to
    school, where KVM's father was waiting.     He ran toward the car.
    - 6 -
    KVM got out, but before DPP could follow, Montijo sped off.              He
    drove to a house, where Meléndez spoke to a man DPP didn't know.
    The man ushered the three of them (Montijo, Meléndez, and DPP)
    into a van and drove them back to the housing project, where they
    waited "for things to calm down."        When the coast seemed clear,
    another man drove Montijo and DPP to a street near the school,
    where they dropped off DPP.
    The Trial
    A federal grand jury indicted Montijo and Meléndez on a
    slew of sex crime charges.      Specifically, count one charged that
    Montijo "used a facility and means of interstate commerce, namely
    the   cellular   phone   application   'KIK,'   to   knowingly    persuade,
    induce, entice, and coerce a 13-year-old minor female [DPP] to
    engage in sexual activity for which any person may be charged with
    a criminal offense under the laws of . . . the Commonwealth of
    Puerto Rico," which violated 
    18 U.S.C. § 2422
    (b).                Four other
    counts (one per victim per drive) charged him with transporting
    the minors in a "commonwealth, territory, or possession of the
    United States" with the same illicit intent, violating 
    18 U.S.C. § 2423
    (a).
    The indictment charged Meléndez under the same statutes
    and added four unrelated charges against him for producing child
    pornography, which agents had found stored on his cell phone when
    - 7 -
    they searched it.3       Before long, Meléndez entered a plea deal with
    the   government   and    copped    to   one   count    of   producing   child
    pornography.   In exchange, the government dropped the remaining
    counts.   He was sentenced to 192 months in prison.
    Montijo   went    to    trial.4     To    prove    its   case,   the
    government called CAP, DPP, the motel owner (to describe the
    joint), KVM's father, and several government agents from the
    Department of Homeland Security Investigations (HSI) task force
    who'd investigated the case.             CAP told the jury how she met
    Meléndez at the family party and narrated the first drive to the
    motel, when Meléndez had sex with her.              Then DPP recounted both
    drives, the KIK chats, and how Montijo had sex with her on the
    second trip to the motel.         By the end of her testimony, when she
    3When they searched Meléndez's phone,            agents found several
    videos of Meléndez having sex with at least             one other minor girl
    who confirmed in an interview that she was             sixteen at the time.
    See United States v. Montijo-Maysonet, 
    318 F. Supp. 3d 522
    , 535
    (D.P.R. 2018).
    4Before that, as we'll explain later, Montijo moved the trial
    judge to dismiss the transportation charges, arguing that based on
    United States v. Maldonado-Burgos, 
    844 F.3d 339
     (1st Cir. 2016),
    § 2423(a) required travel to or from Puerto Rico and did not apply
    to drives wholly within the island.      The district judge denied
    the motion, holding, as we later did, that § 2423(a) covers
    defendants who transport a minor wholly within Puerto Rico. See
    Cotto-Flores, 
    2020 WL 4582283
    , at *9.

    described how Montijo told her he'd "wait for [her] to come out
    from high school" and "take care of [her]," DPP broke down sobbing.
    In his defense, Montijo did not dispute DPP's story or
    try to undermine her testimony.     He agreed that the two went on a
    "blind date" set up by Meléndez, and that on the second "date,"
    they "had sex" (quotes from his lawyer's opening statement).         But
    he claimed that he thought DPP was older.            During DPP's cross
    examination,   Montijo's   lawyer   got   her   to   describe   Montijo's
    reaction to the notebook ("If I knew you were thirteen I wouldn't
    have done it") and hammered that line home in her statements to
    the jury.
    Among other witnesses, the government called HSI Special
    Agent Jose García, who testified he took Montijo's phone during
    the arrest and sent it to forensics to extract the data.            Then,
    over Montijo's objections (more on them later), Task Force Officer
    Kimbelly Pérez-Morales took the stand to identify the report
    showing the texts found on Montijo's phone.            As Officer Pérez
    explained, the report showed that on the morning of November 24,
    2015, before the duo picked up DPP and CAP for the first motel
    trip, Montijo texted Meléndez to ask what he was wearing to meet
    the girls — a pair of "white Nike shorts, a tank top and white
    Nike tennis shoes," answered Meléndez.     Before they left, Meléndez
    - 9 -
    texted Montijo, "Broooo you are horny like a dog.            hahahaha."5    He
    told Montijo they were "leaving at about 7:55" and that "[w]e have
    to take them [back] before 11."       Meléndez explained:       "we have to
    leave these girls before others from Marchand" (the middle school)
    "are out at noon and catch us.    Hahahaha."
    The jury found Montijo guilty on all counts.            The judge
    denied Montijo's motions for judgment of acquittal and sentenced
    him to 198 months in prison.    Montijo now appeals.
    OUR TAKE
    Sufficiency
    We start with Montijo's sufficiency challenges, which he
    mounts against each count of conviction.         First, he claims there
    was too little evidence to show he used KIK to "persuade, induce,
    entice, or coerce" DPP to have sex, as § 2422(b) demanded. Second,
    he argues that the proof was too thin to show he knew DPP was
    underage, which the jury had to find to convict him under either
    statute   of   conviction.    Finally,     he   turns   to   the   last    two
    "transportation"    charges   under    §   2423(a),     arguing    that    the
    5 Meléndez actually said, "estas pegado como los perros," a
    Puerto Rican colloquialism. According to the trial judge (with
    whom defense counsel agreed), the phrase literally translates to
    "stuck like dogs," which alludes to when "dogs . . . are stuck
    together" while mating. The defense pointed out that it doesn't
    quite mean "horny like a dog," as the interpreter translated, but
    the government thought that was the "best available translation,"
    and the district court let it stand. Montijo hasn't challenged
    that decision on appeal, so we assume that "horny" roughly captures
    how Meléndez described Montijo.
    - 10 -
    government didn't prove he intended CAP or KVM to have sex with
    Meléndez when he drove them to the motel.                Montijo argues — as he
    must to show insufficiency — that these holes in the government's
    case   mean    that   no     rational   jury     could   have    found    "beyond    a
    reasonable     doubt"      that   the   government       "proved   the    essential
    elements of the crime."           United States v. Dwinells, 
    508 F.3d 63
    ,
    72 (1st Cir. 2007).          If Montijo is right, we must order acquittal.
    See Burks v. United States, 
    437 U.S. 1
    , 18 (1978) (holding that
    "the Double Jeopardy Clause precludes a second trial once the
    reviewing court has found the evidence legally insufficient").                      So
    we tackle these challenges first and take them in order.
    Count One:      Enticement
    To prove the first count, the government had to show
    that (as charged in the indictment) Montijo used KIK, a "means of
    interstate commerce," to "persuade, induce, entice, or coerce" DPP
    to "engage in any sexual activity for which any person can be
    charged with a criminal offense."            
    18 U.S.C. § 2422
    (b).         Here, the
    "criminal offense" the government alleged Montijo "enticed" and
    "induced" was sexual assault under Puerto Rico law.                    See 
    P.R. Laws Ann. tit. 33, § 5191
    (a) (defining sexual assault to include sex
    with someone under sixteen); United States v. Saldaña-Rivera, 
    914 F.3d 721
    ,    724    (1st    Cir.   2019)     (explaining      that    the   alleged
    - 11 -
    "chargeable sexual activity" under § 2422(b) "includes crimes
    defined by" state and Puerto Rico law).
    Montijo's opening shot takes aim at the first element:
    he urges that "no evidence, other than" DDP's "uncorroborated"
    testimony, showed that he used KIK to chat with her.            But even
    uncorroborated testimony can suffice to sustain a conviction.        See
    United States v. Gaudet, 
    933 F.3d 11
    , 15 (1st Cir. 2019) (holding
    a minor victim's uncorroborated testimony sufficed); United States
    v. Cortés–Cabán, 
    691 F.3d 1
    , 14 (1st Cir. 2012) (explaining that
    "[w]e   repeatedly   have   held    that"   even   "'the   uncorroborated
    testimony of a cooperating accomplice may sustain a conviction so
    long as that testimony is not facially incredible'" (quoting United
    States v. Torres–Galindo, 
    206 F.3d 136
    , 140 (1st Cir. 2000))).
    And here, DPP's story wasn't uncorroborated; CAP backed it up,
    telling the jury that Montijo and DPP texted each other while CAP
    chatted with Meléndez.      And DPP's story went unrebutted.      So the
    jury could easily have bought it.
    Even so, Montijo argues, the messages DPP testified he
    sent over KIK — that he "wanted to see [DPP] again" and to go on
    another "vuelta" to the motel, which they planned on the app —
    were not "coercive or enticing in nature."         He points out that in
    our cases applying § 2422(b) thus far, the defendants sent lewd
    online messages (to the minor or an adult they thought was the
    minor's parent) that expressly referenced sex acts.           See United
    - 12 -
    States v. Dávila-Nieves, 
    670 F.3d 1
    , 3–6, 11 (1st Cir. 2012);
    United States v. Berk, 
    652 F.3d 132
    , 134–35, 140 (1st Cir. 2011);
    Dwinells, 
    508 F.3d at 73
    .       Other circuits agree that "when a
    defendant   initiates   conversation    with    a   minor,   describes   the
    sexual acts that he would like to perform on the minor, and
    proposes a rendezvous to perform those acts, he has crossed the
    line toward persuading, inducing, enticing, or coercing a minor to
    engage in unlawful sexual activity."           United States v. Goetzke,
    
    494 F.3d 1231
    , 1237 (9th Cir. 2007).6      But those cases didn't draw
    a line in the sand to insist on explicit sexual overtures.               Nor
    did Congress, which meant to cast a broad net (consistent with the
    Constitution) to catch predators who use the Internet to lure
    children into sexual encounters.       See H.R. Rep. 105-557, 21, 1998
    U.S.C.C.A.N. 678, 678–79, 690 (June 3, 1998).7          In line with that
    6 In those cases, the defendants never had sex with their
    targets, like Montijo did. They were your typical to-catch-a-
    predator scenarios, where the defendant is arrested before he meets
    the child, or the "child" is a federal agent in disguise. The
    defendants were charged with "attempt[ing]" to "persuade, induce,
    entice and coerce" a minor, which is also a crime under § 2422(b).

    7 As the Third Circuit has explained, "[t]he first version of
    § 2422(b) . . . was attached to the Telecommunications Act of 1996"
    with "very little" legislative comment. United States v. Tykarsky,
    
    446 F.3d 458
    , 467 n.4 (3d Cir. 2006).          "Because the Child
    Protection and Sexual Predator Punishment Act of 1998 rewrote
    § 2422(b)," raised the maximum penalty, "and made substantial
    changes to related laws," including § 2422(a), courts have looked
    to its legislative history to shed light on § 2422's purpose and
    - 13 -
    intent, the four verbs Congress used — including "entice" and
    "induce"    —   plainly     reach    implicit   coaxing    or   encouragement
    designed to "achieve . . . the minor's assent" to unlawful sex.

    ; see Webster's Third New Int'l Dictionary,
    Unabridged,     available    at     http://unabridged.merriam-webster.com
    (defining "entice" as "to draw on by arousing hope or desire:
    allure, attract" and "induce" as "to move and lead . . . by
    persuasion or influence").          That makes sense:     people "entice" and
    "induce" each other to have sex all the time without spelling it
    out.
    That's just what Montijo did here — so the jury could've
    found.     Remember, when he texted DPP on KIK, they'd already gone
    on one "ride."    And it wasn't to a McDonald's:          He drove to a motel
    that (it could be inferred without much effort) was designed for
    scope.

     The House Judiciary Committee explained that the 1998
    Act responded to "highly publicized news accounts in which
    pedophiles" used the web to "seduce or persuade children to meet
    them to engage in sexual activities," and confirmed its intent to
    enact "a comprehensive response to the horrifying menace of sex
    crimes against children, particularly assaults facilitated by
    computers . . . by providing law enforcement with the tools it
    needs to investigate and bring to justice those individuals who
    prey on our nation's children." H.R. Rep. 105-557, 10, 21, 1998
    U.S.C.C.A.N. 678, 678–79, 690 (June 3, 1998); see also id. at 21
    (explaining that the bill expanded § 2422(a) to "enable law
    enforcement to charge a defendant who attempts to lure individuals
    into illegal sexual activity" even where "the travel did not take
    place"); United States v. Nestor, 
    574 F.3d 159
    , 162 (3d Cir. 2009)

    aggressively   combat   computer-related    sex   crimes   against
    children").

    discrete sex, where the men each paid $20 for a few hours and
    coupled off with one of the girls.             Once alone in the bedroom,
    Montijo wooed DPP — told her she had "beautiful eyes and hair" —
    and assured her she "didn't have to do anything [she] didn't want
    to,"    a   ploy   (the   jury   could've   thought)   to   gain   her   trust.
    Meanwhile, CAP and Meléndez actually had sex in the other room
    (something Meléndez and CAP likely told their companions about,
    the jury could reason).          And before all this went down, Meléndez
    had told Montijo he was "horny like a dog."            Jurors don't have to
    check "common sense" or "mature experiences" at the courthouse
    door.       United States v. Hernandez, 
    995 F.2d 307
    , 314 (1st Cir.
    1993) (quoting United States v. Ortiz, 
    966 F.2d 707
    , 712 (1st Cir.
    1992)).      With that context in mind, the jury could have used those
    attributes to find that by telling DPP he wanted to get another
    room together at the motel where her friend had had sex with
    Meléndez the first go-round, and by making a plan to do so, Montijo
    meant to "entice" and "induce" her to meet up for sex.                   And it
    could have inferred he succeeded.             After all, when the two met
    again (the jury could've found), Montijo got exactly what he
    wanted.      See United States v. Montijo-Maysonet, 
    318 F. Supp. 3d 522
    , 530 (D.P.R. 2018) (rightfully pointing out that DPP "traveled
    to the Jackeline Motel [the second time] only because she and
    Montijo planned the . . . 'ride' on KIK," and observing that the
    fact that DPP had sex with Montijo "only after exchanging text
    - 15 -
    messages     on   KIK    supports     the   inference    that    [   ]   Montijo's
    communications persuaded" her to do so).
    Which      brings   us   to    Montijo's    last    attack    on    the
    enticement count.         Montijo argues that to prove he "knowingly"
    enticed or induced DPP to have sex "for which [he could] be
    charged" under Puerto Rico law, the government had to prove he
    knew DPP was under sixteen years old (the Puerto Rico age of
    consent, 
    P.R. Laws Ann. tit. 33, § 5191
    (a)) when he sent the KIK
    messages.8        The   government    counters    that   at     least    two   other
    circuits have held that § 2422(b) does not permit a mistake-of-
    age defense.       See United States v. Banker, 
    876 F.3d 530
    , 539–40
    (4th Cir. 2017); United States v. Daniels, 
    685 F.3d 1237
    , 1246–50
    (11th Cir. 2012); but see United States v. Cote, 
    504 F.3d 682
    , 686
    (7th Cir. 2007) (reading the statute to require knowledge the
    victim was under eighteen to avoid a First Amendment problem);
    United States v. Meek, 
    366 F.3d 705
    , 718 (9th Cir. 2004) (holding
    "that the term 'knowingly' refers both to the verbs — 'persuades,
    8 Montijo also argues that § 5191(a) — the Puerto Rico offense
    at issue — requires the defendant to know the victim was under
    sixteen when they had sex. But he does not explain why this would
    matter, since § 2422(b) does not demand the defendant commit — or
    even intend to commit — the local offense itself, see Dwinells,
    
    508 F.3d at 71
     (holding, again, that § 2422(b) "criminalizes an
    intentional attempt to achieve a mental state — a minor's assent
    — regardless of the accused's intentions vis-à-vis the actual
    consummation of sexual activities with the minor"); Saldaña-
    Rivera, 914 F.3d at 724 ("Nothing in the language of section
    2422(b) requires the government to show that Saldaña himself could
    have been charged under Article 130.").
    - 16 -
    induces, entices, or coerces' — as well as to the object — 'a
    person who has not achieved the age of 18 years'").      The trial
    judge held that our decision in Dwinells puts us on the Seventh
    and Ninth Circuits' side of the split; and as a result, he held
    that the government had to prove Montijo knew DPP was under
    eighteen.   See United States v. Montijo-Maysonet, 
    292 F. Supp. 3d 568
    , 569 (D.P.R. 2018) (citing Dwinells, 
    508 F.3d at 68, 71
    (concluding that § 2422(b) did not raise First Amendment issues
    because it "requires that a defendant possess the specific intent
    to persuade, induce, entice, or coerce a minor into committing
    some illegal sexual activity," and "[s]peech intended deliberately
    to encourage minors' participation in criminal sexual conduct" can
    constitutionally be outlawed)(emphasis the trial judge's)).     In
    essence, Montijo goes one step further, arguing that the word
    "knowingly" in § 2422(b) requires the defendant to know not only
    that the victim was under eighteen, but that someone could be
    "charged with a criminal offense" for having sex with her — and
    since the relevant Puerto Rico offense requires the victim be under
    sixteen, the government had to show Montijo knew that, too, when
    he did the enticing.
    But even if Montijo is right on the law — an issue we
    don't decide — the jurors had ample evidence that Montijo knew DPP
    was younger than sixteen when he texted her.     For starters, he
    picked her up outside a middle school.   And Montijo knew DPP went
    - 17 -
    to school there:   Meléndez texted him that morning that they had
    to drop the girls off at "Marchand" (the name of the school).   The
    jurors' "collective experience" would have told them that middle
    schoolers are rarely over fifteen years old.   See United States v.
    Hamie, 
    165 F.3d 80
    , 84 (1st Cir. 1999) (explaining that jurors can
    "take full advantage of their collective experience and common
    sense" (quoting United States v. O'Brien, 
    14 F.3d 703
    , 708 (1st
    Cir. 1994))); Tr. of Trial Day 2 at 103 (where the judge noted
    that "16-year-olds are usually in eleventh grade").   The evidence
    also suggested Montijo knew they'd be in trouble if someone caught
    them with the girls.     Before the first drive, Meléndez texted
    Montijo that they "had to leave" DPP and CAP before "others from
    Marchand" realized they were gone, so no one would "catch" the
    men.   And when they did drop the girls off, Montijo and Meléndez
    insisted they get out a few blocks away from the building, so
    school staff wouldn't see them.   To top it off, photos of DPP and
    her friends showed the jurors how the children looked in 2015 —
    well under sixteen, the jury could have found.
    In his defense, Montijo stresses his reaction when DPP
    told him she was thirteen:    he exclaimed that Meléndez had told
    him she was older, and that he "wouldn't have done it" if he'd
    known her real age.    But given the swell of other proof washing
    over them, the jurors could have reasonably found that Montijo's
    protestations just confirmed he knew DPP was underage.   Conscious
    - 18 -
    he broke the law (they could have inferred), he feigned shock to
    cover his own hide, hoping DPP would buy it and vouch for him if
    the cops found out.    In short, the jurors didn't have to believe
    the excuse Montijo gave DPP.    Such credibility determinations are
    "uniquely" theirs (not ours) to make. See United States v. Rivera-
    Ruiz, 
    244 F.3d 263
    , 268 (1st Cir. 2001).
    The Transportation Counts
    Undeterred, Montijo moves to the four § 2423(a) counts,
    which charged that he "knowingly transported" CAP, DPP, and KVM in
    a "commonwealth, territory, or possession of the United States"
    with the intent that each engage in sexual activity for which
    someone (either he or Meléndez) could be charged with a crime —
    again, sexual assault under Puerto Rico law.      
    18 U.S.C. § 2423
    (a);
    see also 
    P.R. Laws Ann. tit. 33, § 5191
    (a).
    On that score, he first claims that that statute requires
    travel "in interstate or foreign commerce with respect to [Puerto
    Rico]," and doesn't cover rides from schools to motels within the
    island's borders.   But we recently rejected that argument, holding
    Puerto Rico is a "commonwealth" within the meaning of the Act.
    See Cotto-Flores, 
    2020 WL 4582283
    , at *7–9; 
    18 U.S.C. § 2423
    (a)
    (covering transportation "in any commonwealth . . . of the United
    States").    If that's true, Montijo claps back, then the statute
    violates the equal protection component of the Fifth Amendment,
    because it treats defendants who transport minors within Puerto
    - 19 -
    Rico differently from those who do the same thing within a state,
    with no justification for the disparity.
    Ordinarily, a law survives an equal protection challenge
    if the distinction it draws is "rationally related to a legitimate
    government interest."     United States v. Vaello-Madero, 
    956 F.3d 12
    , 18 (1st Cir. 2020) (quoting U.S. Dep't of Agric. v. Moreno,
    
    413 U.S. 528
    , 533 (1973)).    Montijo urges that in this case, our
    review should have more bite.       Laws that single out certain
    "discrete and insular minorities" who lack political power for
    disfavored treatment, Bruns v. Mayhew, 
    750 F.3d 61
    , 66 (1st Cir.
    2014) (quoting Graham v. Richardson, 
    403 U.S. 365
    , 372 (1971)), or
    intentionally classify people "based on national origin, ancestry,
    and race" must "withstand the strictest constitutional scrutiny,"
    DiMarco-Zappa v. Cabanillas, 
    238 F.3d 25
    , 36 (1st Cir. 2001).    In
    Montijo's view, that's the deal here.    People in Puerto Rico (he
    urges) are a protected class — so by targeting them, § 2423(a)
    triggers strict scrutiny.     And even if not, Congress lacked a
    rational basis to regulate conduct in Puerto Rico that it does not
    regulate in the states.
    As Montijo concedes, he did not raise this claim below,
    so we review it for plain error — a "demanding" uphill climb.
    United States v. Ríos-Rivera, 
    913 F.3d 38
    , 43 (1st Cir. 2019).   To
    scale its heights, Montijo had to identify "controlling precedent"
    that made it "indisputable" that § 2423(a) violates the Fifth
    - 20 -
    Amendment.   Id. (quoting United States v. Morosco, 
    822 F.3d 1
    , 21
    (1st Cir. 2016)).     He hasn't done so.   To be sure, it's crystal
    clear a law targeting people of Puerto Rican origin would draw the
    strictest scrutiny.     See DiMarco-Zappa, 
    238 F.3d at 36
    .      But
    § 2423(a) has a broader sweep:     it applies to anyone (tourists,
    transplants, and travelers) who transports a minor for criminal
    sex on the island.     No controlling case holds that folks join a
    protected class once they set foot in Puerto Rico.    Indeed, under
    existing precedent, even the millions of U.S. citizens who live
    there — who can't influence by vote the federal laws that regulate
    them (unless they leave their homes for the mainland) — have not
    been recognized as a protected class, even though they're "the
    very essence of a politically powerless group."    United States v.
    Vaello Madero, 
    356 F. Supp. 3d 208
    , 214 (D.P.R. 2019).   Rather, in
    Harris v. Rosario, the Court held that, without violating the
    Constitution's Equal Protection mandate, Congress could "treat
    Puerto Rico differently from States so long as there [was] a
    rational basis for its actions."   
    446 U.S. 651
    , 651–52 (1980); see
    also Vaello-Madero, 956 F.3d at 21–23 (holding it was "beyond
    question" that "precedent require[d] us to apply rational basis
    review to the question before us" — whether a federal benefit
    program that discriminated against Puerto Rico residents violated
    - 21 -
    Equal    Protection    —     while   noting     that    Harris    was   a   summary
    disposition that should be read narrowly).
    Therefore, in Ríos-Rivera, we rejected the same argument
    Montijo raises — that § 2423(a) warrants "heightened scrutiny"
    even on plain error review — because Harris foreclosed it.                     913
    F.3d at 44.   Like Montijo, "Ríos d[id] not seriously challenge the
    notion that Congress may have limited [§ 2423(a)]'s applicability
    within the fifty states because it implicitly recognized potential
    constitutional limits on its power."                 Id.; see United States v.
    Morrison, 
    529 U.S. 598
    , 618 (2000) (blocking a Congressional
    attempt to regulate intrastate violence "not directed at the
    instrumentalities,         channels,    or   goods     involved    in   interstate
    commerce," whose regulation "has always been the province of the
    States").     We     held,    therefore,      that    § 2423(a)'s   differential
    treatment of states and territories did not clearly lack a rational
    basis.    See Ríos-Rivera, 913 F.3d at 44.             And so we must here.
    Having    struck     out    swinging      at   the   statute    itself,
    Montijo turns back to the facts. As the judge instructed, to prove
    the four § 2423(a) counts, the government had to show:                       first,
    that Montijo transported DPP, CAP, and KVM within Puerto Rico;
    second, that each girl was then under eighteen; and third, that
    when Montijo transported each girl, he intended she engage in
    "sexual activity" for which someone could be charged with a
    criminal offense under Puerto Rico law.                Montijo doesn't dispute
    - 22 -
    the first two elements.       Instead, he argues the evidence was
    insufficient to prove he intended CAP, DPP, or KVM to have unlawful
    sex when he took them to the motel.
    This claim has two parts.   First, Montijo raises another
    mistake-of-age argument: that he did not know the girls were under
    sixteen (Puerto Rico's age of consent, remember) when he drove
    them to the motel.       We've already held that to convict under
    § 2423(a), the jury need not find the defendant knew the person he
    carted off had "not attained the age of 18 years" such that the
    statute covered them.     
    18 U.S.C. § 2423
    (a); see United States v.
    Tavares, 
    705 F.3d 4
    , 20 (1st Cir. 2013).       Undaunted, Montijo (as
    in his § 2422(b) argument above) urges that a defendant can't
    "inten[d]" that a minor "engage" in sex "for which any person can
    be charged with a criminal offense" unless he knows that the sex
    would be criminal under local law; so when the alleged local
    offense is statutory rape of a minor, he must know the victim was
    under the local-law age of consent to have the "intent" § 2423(a)
    requires.9
    Second, Montijo urges that even if he can't raise a
    mistake-of-age defense — or even if the evidence showed he knew
    9 Montijo also argues, as he did with § 2422(b), that when
    the intended local offense permits a mistake-of-age defense,
    § 2423(a) should too. But as above, we need not reach this claim.
    - 23 -
    the girls were too young — the jury could not have concluded he
    intended all three to have sex once they got to the motel.
    Once again, however — even if Montijo is right on the
    law (an issue we need not decide) — the jury had ample proof that
    he knew the victims were each under sixteen, and that he intended
    they'd have sex with one of the men when he took them to El
    Jackeline.    In case you forgot:   as to their age, the girls' child-
    like looks and the school they emerged from were dead giveaways,
    the   jury   could've   found.   If   that   didn't   tip   off   Montijo,
    Meléndez's instructions — to drop them off at the school before
    noon so staff wouldn't "catch us" — would have raised some red
    flags.   So did the school uniforms DPP and KVM wore on the second
    trip.    Rounding things off, Montijo's evasive behavior — dropping
    the girls off down the street from the school so staff wouldn't
    see them — would have shown he got the picture.             See Pueblo v.
    Alicea Hernández, 
    2014 WL 7500964
    , at *19 (P.R. App. Ct. 2014)
    (finding sufficient evidence to reject mistake-of-age defense
    under § 5191(a) where defendant met a 15-year-old at school and
    took her to a motel, where she hid in the back of the car to avoid
    being seen).    And as for intent, between Meléndez's texts (calling
    Montijo "horny"), Montijo's flirting (telling DPP she had pretty
    hair and eyes), the offers to give the girls smokes and drinks,
    and, oh right — the two drives to a sex motel — the jury had what
    it needed to convict.     See United States v. Ray, 
    831 F.3d 431
    , 434
    - 24 -
    (7th Cir. 2016) (holding that defendant's actions in offering minor
    alcohol and marijuana, checking into a motel room for a four-hour
    stay, and having sex with the minor sufficed to show his intent to
    have sex with her); see also United States v. Morales–de-Jesús,
    
    372 F.3d 6
    , 21 (1st Cir. 2004) (explaining that "[w]hen a plausible
    read of the record supports the verdict, we will not overturn the
    jury's determination on appeal").
    Officer Pérez's Testimony
    Having lost his sufficiency challenges, Montijo launches
    a procedural attack.        He argues that the trial judge should not
    have let Officer Pérez testify about the text messages taken off
    Montijo's cell phone, and about the KIK application itself, without
    being qualified as an expert in "cell phone extractions or forensic
    analysis."    Appellant's Br. at 27; see Fed. R. Evid. 701, 702.             We
    test such claims for abuse of discretion.             See United States v.
    Spencer, 
    873 F.3d 1
    , 14 (1st Cir. 2017).
    In   the   world   of   evidence,   there   are   two   kinds   of
    witnesses:    lay witnesses and experts.         To give an expert opinion,
    a witness must be "qualified" by "knowledge, skill, experience,
    training, or education" to do so, and the judge must vet the
    opinion to ensure it's "reliable."            Fed. R. Evid. 702; see Lawes
    v. CSA Architects & Eng'rs LLP, 
    963 F.3d 72
    , 97 (1st Cir. 2020)
    - 25 -
    (citing Daubert v. Merrell Dow Pharm., 
    509 U.S. 579
    , 589 (1993)).
    Lay witnesses not so qualified may only give testimony that is
    (a) rationally based on the witness's perception;
    (b) helpful to clearly understanding the witness's
    testimony or to determining a fact in issue; and (c) not
    based on scientific, technical, or other specialized
    knowledge within the scope of Rule 702.
    Fed. R. Evid. 701.     That last (c) prong was added to "eliminate
    the risk that the reliability requirements set forth in Rule 702
    will be evaded through the simple expedient of proffering an expert
    in lay witness clothing."     Fed. R. Evid. 701, Advisory Committee's
    note to the 2000 amendments.         In short, a lay opinion must
    "result[ ] from a process of reasoning familiar in everyday life."
    Id.; see United States v. Vega, 
    813 F.3d 386
    , 394 (1st Cir. 2016).
    As best we can tell, Montijo urges that two opinions
    Pérez gave relied on expert knowledge.10     First, Pérez identified
    words on a spreadsheet (a/k/a, an "extraction report") as the text
    messages Montijo exchanged with Meléndez, which agents extracted
    from    Montijo's   cell   phone.   The   government   argues   Pérez's
    "testimony was limited to the fact that . . . she had seen the
    data extraction report from Montijo's cell phone and recognized it
    in court."    In fact she went further than that:      she identified
    certain texts (e.g., "what are you wearing") as messages sent from
    10
    Since Montijo doesn't develop any claim for why any other
    statements Pérez made required expert knowledge, we deem other
    such arguments waived. See United States v. Zannino, 
    895 F.2d 1
    ,
    17 (1st Cir. 1990).

    Montijo to "Puky" (Meléndez's nickname, remember) and other texts
    (e.g., "you are horny like a dog") as sent from "Puky" to Montijo.
    She also testified to the date and time the texts were sent.          To
    do so, however, all she did was to read from the report, which
    labeled each string of text as an "SMS message" "to Puky" or "from
    Puky," with the date and time.    Montijo does not explain why this
    testimony     required   "scientific,    technical,    or    specialized
    knowledge."    And we conclude it didn't.
    These days, most anyone with a cellphone knows they store
    information about text messages, including the sender, recipient,
    and content.    You don't need to be a software engineer to pick up
    a cellphone, open a messaging application, and interpret the words
    in the bubbles as messages sent and received.               In doing so,
    ordinary people rely on a "process of reasoning familiar in
    everyday life," not any expert knowledge about software coding or
    cellphone circuitry.     If Officer Pérez had opened Montijo's phone
    and taken screenshots of his conversations with Meléndez, no one
    suggests she'd need any "scientific, technical, or specialized
    knowledge" to identify them as text messages.         See United States
    v. Ganier, 
    468 F.3d 920
    , 926 (6th Cir. 2006) (noting that certain
    "[s]oftware programs . . . may be as commonly used as home medical
    thermometers," such that "[t]he average layperson today may be
    - 27 -
    able to interpret the[ir] outputs . . . as easily as he or she
    interprets everyday vernacular").
    In this case, investigators used forensic software to
    copy that same info from Montijo's phone and display it on paper.
    To be sure, most of us don't see "extraction reports" every day.
    But as we've held time and again, Rule 701 lets in "particularized
    knowledge" that police officers gain on the job, so long as it's
    "well founded on [their] personal knowledge and susceptible to
    cross examination."     Vega, 813 F.3d at 394 (explaining that in
    this circuit, a "police officer noticing patterns of behavior
    across criminal operations" — like code words or what a "drug
    point" looks like — "uses straightforward logic to conclude a
    defendant's behavior fits within that pattern and thus, does not
    need to be qualified as an expert") (quoting United States v.
    Ayala-Pizarro, 
    407 F.3d 25
    , 28 (1st Cir. 2005))); see also United
    States v. Belanger, 
    890 F.3d 13
    , 25 (1st Cir. 2018) ("[T]ime and
    again we have stated that Rule 701 lets in 'testimony based on the
    lay expertise a witness personally acquires through experience,
    often on the job.'" (quoting United States v. George, 
    761 F.3d 42
    ,
    59 (1st Cir. 2014))).
    No less than an experienced drug agent decoding drug
    deals, or an investigator construing a plain-language billing
    chart he found in a suspect's home, see Vega, 813 F.3d at 395
    (holding that a lay case agent properly "interpreted a chart
    - 28 -
    listing medical equipment and containing a column reading 'Rep.
    payment' as evidence that" the defendant's medical-device company
    paid sales reps illegal kickbacks "based on the equipment they
    sold"), Pérez simply interpreted the plain language (like "SMS
    message" and, well, "to" and "from") on the spreadsheet, which was
    labeled with the case number and "which phone it was extracted
    from" (Montijo's) — statements that Montijo does not now challenge
    on hearsay grounds.         None of that testimony "turn[ed] on or
    require[d]   a   technical    understanding    of   the   programming   or
    internal   mechanics   of    the   [forensic   extraction]   technology."
    United States v. Marsh, 
    568 F. App'x 15
    , 17 (2d Cir. 2014) (holding
    agent's testimony that he used software to "retrieve text messages
    and other data from a cellular phone" and explaining "the contents
    of the messages retrieved from the phone" was lay testimony for
    that reason); see also United States v. McLeod, 
    755 F. App'x 670
    ,
    673 (9th Cir. 2019) (same).11         She relied on simple "logic and
    11Under Rule 701(b), "where the witness is no better suited
    than the jury to make the judgment at issue," the opinion must be
    excluded to "provid[e] assurance against the admission of opinions
    which would merely tell the jury what result to reach." United
    States v. Vázquez–Rivera, 
    665 F.3d 351
    , 363 (1st Cir. 2011)).
    Montijo does not argue that Pérez's testimony was inadmissible
    under that prong, so we do not address that issue. See Zannino,
    
    895 F.2d at 17
     (explaining that arguments undeveloped on appeal
    are waived).

    life."    Vega, 813 F.3d at 394–95.12
    Second, Pérez testified that KIK is "different from
    other instant text messaging services" because "once the messages
    have been deleted they can't be recovered from the phone," "even
    with . . . law enforcement forensic tools."   She knew this, Pérez
    said, because she'd become "familiar" with KIK through her "duties
    investigating child exploitation crimes."     Montijo objects that
    this was an expert conclusion that required technical knowledge
    about the KIK application.      In the government's eyes, though,
    Pérez's two cents about the app relied on nothing more than "lay
    expertise" she'd gained "through experience . . . on the job" —
    which made it admissible.    United States v. Habibi, 
    783 F.3d 1
    , 5
    (1st Cir. 2015) (quoting George, 761 F.3d at 59).
    This one is a closer call, but Habibi is a helpful
    guidepost. In that case — a prosecution for illegal gun possession
    12 By the way, Pérez "offered no assurances about how well
    [the extraction software] performed." United States v. Chavez-
    Lopez, 
    767 F. App'x 431
    , 434 (4th Cir. 2019) (finding no plain
    error in admitting agent's testimony identifying text messages
    he'd extracted from cell phone). Had Montijo wanted to challenge
    the reliability of the extraction process or suggest the software
    may have malfunctioned, he could have called his own expert or the
    forensic analyst(s) who conducted the extraction. As it stands
    however, aside from his Rule 701 argument, he does not contend
    that the jury lacked a sufficient basis to conclude that the data
    on the extraction report was just what Pérez "purported [it] to
    be." United States v. Appolon, 
    715 F.3d 362
    , 371 (1st Cir. 2013)
    (discussing the requirements for authenticating evidence).

    — eyewitnesses had testified they saw the defendant pick up the
    gun with his bare hands and stash it in his basement.              
    Id. at 3
    .
    Yet, test results found no DNA on the gun that belonged to the
    defendant.     
    Id. at 4
    .    To show the negative tests didn't doom its
    case, the government called an FBI agent to testify that he'd
    worked on cases "in which [his] investigation revealed that an
    individual touched or handled a[n] object with a bare hand, but
    when tested, no detectable DNA was found on that object."             
    Id. at 5
    .   Over the defendant's objection, we held that the challenged
    testimony relied "only on [the agent's] investigative experience"
    and so fell "'comfortably within the boundaries of lay opinion
    testimony.'"      
    Id.
     at 5–6 (quoting United States v. Valdivia, 
    680 F.3d 33
    , 50 (1st Cir. 2012)).
    Officer Pérez's testimony skirted closer to the line.
    Instead of just saying she'd worked on cases in which suspects
    sent messages on KIK that weren't recovered, she went a step
    further   —    testifying   that   the   government's   forensic    software
    "can't" recover KIK messages once they've been deleted.                 That
    conclusion arguably "require[d] a technical understanding" of the
    government's forensic tools and their capabilities.         Marsh, 568 F.
    App'x at 17.      But even if it was error to admit that testimony,
    the mistake was harmless.          See Kotteakos v. United States, 
    328 U.S. 750
    , 765 (1946) (explaining that, even if the trial judge
    erred, we should affirm if the record minus the improper testimony
    - 31 -
    gives us "fair assurance . . . that the [jurors'] judgment was not
    substantially swayed by the error").     On direct, Pérez made clear
    that, like the agent in Habibi, she was testifying based only on
    her lay experience in past investigations with the task force.
    And on cross-examination, she made it pellucid that she had no
    "training in forensic tools."     Those clarifications dampened the
    risk that the jury gave determinative weight to her description of
    the government's forensic capabilities.     See Torres-Galindo, 
    206 F.3d at 141
     (holding agent's arguably improper expert testimony to
    be harmless based on his "extensive[ ] cross-examin[ation] by
    defense counsel" and the weight of the evidence against the
    defendant).
    This and the other evidence that Montijo used KIK to
    entice DPP makes it "highly probable" that Pérez's testimony about
    the app "did not contribute to the verdict."      Vega, 813 F.3d at
    395 (quoting United States v. Amador-Huggins, 
    799 F.3d 124
    , 129
    (1st Cir. 2015)).    Remember, DPP testified that Montijo used the
    app to get her to go on the second "vuelta" — and CAP confirmed he
    and DPP texted each other.   Montijo never seriously disputed DPP's
    testimony — indeed, just the opposite: he asked the jury to credit
    her account of his "shock" in the motel room (when he "learned"
    she was thirteen).     And the motel records, KVM's father, and
    Montijo's text messages backed up the main thrust of her story.
    On the other hand, Montijo never argued that the KIK messages were
    - 32 -
    recoverable, or that the government's failure to introduce them
    meant DPP lied when she described them.             Given DPP's otherwise
    corroborated and unrebutted testimony, which Montijo has never
    seriously disputed, it is "highly [im]probable" Pérez's one-liner
    on KIK was the gamechanger. Vega, 813 F.3d at 395 (quoting Amador-
    Huggins, 799 F.3d at 129).13
    Sentence
    His convictions secure, Montijo claims the judge botched
    his sentencing.     In reviewing federal sentences, we take a two-
    step approach: we ensure the judge (first) followed the prescribed
    procedures and (second) imposed a sentence within the range of
    reason.    See Gall v. United States, 
    552 U.S. 38
    , 51 (2007). In
    other     words,   we     review   "for      procedural   and   substantive
    reasonableness."        United States v. Hernandez-Maldonado, 
    793 F.3d 13
     To the extent that Montijo argues that Pérez gave expert
    testimony when she said that KIK used the Internet, that, too, was
    harmless.    As a cell phone application, KIK qualifies as "a
    facility or means of interstate commerce" under § 2422(b) whether
    it used the Internet or a cellular network to send messages. See
    United States v. Evans, 
    476 F.3d 1176
    , 1180 (11th Cir. 2007)
    (explaining that defendant's use of a landline and cell phone was
    enough to establish the "facility or means" element of § 2422(b)
    because     "[t]elephones    and     cellular    telephones     are
    instrumentalities of interstate commerce"); see also United States
    v. Gilbert, 
    181 F.3d 152
    , 158 (1st Cir. 1999) (explaining that "a
    telephone is an instrumentality of interstate commerce" regulable
    under the Commerce Clause); United States v. Giordano, 
    442 F.3d 30
    , 41 (2d Cir. 2006) (holding that a phone is a "facility or means
    of interstate . . . commerce" under a similar statute, 
    18 U.S.C. § 2425
    ).
    - 33 -
    223, 227 (1st Cir. 2015).      Montijo claims the judge flunked both
    tests here.    In his telling, the judge botched the guideline math
    — a "significant procedural error," Gall, 
    552 U.S. at
    51 — and
    imposed an unreasonable sixteen-and-a-half-year sentence.      To test
    these theories, we review the judge's "interpretation of the
    Guidelines de novo, [his] findings of fact for clear error, and
    [his] judgment calls for abuse of discretion."        United States v.
    Houston, 
    857 F.3d 427
    , 432 (1st Cir. 2017).
    Procedural Reasonableness
    Before we flesh out Montijo's claims, here's what you
    need to know.      At each federal sentencing, the judge "must begin
    [his or her] analysis" by calculating the defendant's advisory
    guideline range.     Peugh v. United States, 
    569 U.S. 530
    , 541 (2013)
    (quoting Gall, 
    552 U.S. at
    50 n.6).         The range turns on two
    variables.     First, the U.S. Sentencing Guidelines assign each
    defendant a "total offense level" — a point score based on the
    "specified offense or group of offenses" plus "adjustments for any
    aggravating or mitigating factors."       United States v. Martínez-
    Benítez, 
    914 F.3d 1
    , 2 n.2 (1st Cir. 2019).     Next, they place the
    defendant in a category (I through VI) based on his criminal
    history.     
    Id.
       The judge then plots those two numbers on a chart
    (a/k/a the "sentencing table") and "ends up with an advisory prison
    range," 
    id.
     — the "starting point and the initial benchmark" for
    determining the sentence.     Gall, 
    552 U.S. at 49
    .   "From there, the
    - 34 -
    judge sees if any departures are called for, considers various
    sentencing factors, and determines what sentence (whether within,
    above, or below the suggested range)," Martínez-Benítez, 914 F.3d
    at 2 n.2, is "sufficient" and no more than "necessary" to serve
    the goals of sentencing, 
    18 U.S.C. § 3553
    (a).
    When   a    defendant   is   convicted   of   multiple   counts,
    computing the first factor — the "total offense level" — is "no
    picnic."        United States v. Ponzo, 
    853 F.3d 558
    , 586 (1st Cir.
    2017).     "The guidelines tell courts to 'group' the counts that
    'involv[e] substantially the same harm,' U.S.S.G. § 3D1.2, and
    then      do     'group-by-group,       not     count-by-count,    sentencing
    calculations.'"           Id. (last quoting United States v. Bivens, 
    811 F.3d 840
    , 842 (6th Cir. 2016), and citing U.S.S.G. §§ 3D1.3,
    3D1.4).        "The court then calculates the offense level for each
    count within each group, attributes to each group the highest
    offense level of any count within it, compares the groups to
    ascertain which has the highest offense level, [and] considers
    certain further adjustments[.]"             United States v. Florence, 
    143 F.3d 11
    , 14 (1st Cir. 1998).           Those "further adjustments" include
    an up-to-five level enhancement — also called a "multiple count
    adjustment" — based on the number of groups and their relative
    severity.        See U.S.S.G. § 3D1.4.          Once the judge makes those
    - 35 -
    tweaks, he winds up with the total (or "combined") offense level,
    which he plugs into the chart.       See Florence, 
    143 F.3d at 14
    .14
    The judge worked through that maze here and pegged the
    guideline range at 235–293 months in prison.       He started with the
    base offense level for each of the six counts of conviction, then
    notched them up with a series of enhancements.            Montijo disputes
    three on appeal:    first, the judge added a two-level enhancement
    to each count involving DPP15 because he found Montijo "unduly
    influenced [her] to engage in prohibited sexual conduct." U.S.S.G.
    § 2G1.3(b)(2)(B).    Second, he tacked on two levels to the triplet
    of   counts   derived   from   the   second   daytrip16     because   those
    "offense[s] involved the use a computer or an interactive computer
    service to [ ] persuade, induce, entice, coerce, or facilitate the
    travel of" each minor victim (DPP and KVM) "to engage in prohibited
    sexual conduct."    U.S.S.G. § 2G1.3(b)(3)(A).     Third, after adding
    those plus-factors, the judge found that each offense had inflicted
    14 The grouping rules aim to limit "the significance of the
    formal charging decision and to prevent multiple punishment for
    substantially identical offense conduct" when a defendant is
    charged with "closely intertwined" offenses. USSG Ch.3, pt. D,
    intro. comment. "In essence, counts that are grouped together are
    treated as constituting a single offense for purposes of the
    guidelines." Id.
    15Counts one, three, and five — which charged Montijo enticed
    DPP and transported her twice to engage in unlawful sex acts.
    16 Counts one, five, and six — which charged Montijo enticed
    DPP and transported her and KVM to engaged in unlawful sex acts on
    the second outing.
    - 36 -
    "substantially" separate "harm," U.S.S.G. § 3D1.2, so he didn't
    group them together.       Then, as the Guidelines direct, he took the
    offense with the highest offense level (34) and added a four-point
    multiple-count adjustment.            Id. § 3D1.3, 3D1.4.     The judge made
    all those adjustments over Montijo's objections — which he repeats
    on appeal.    We address his grievances in the order he argues them.
    Montijo    first    complains      that   he   did    not   "unduly
    influence[ ]"    a     minor,    to   trigger   the    two-point    bump   under
    § 2G1.3(b)(2)(B).       To apply that enhancement, the judge had to
    "closely consider the facts of the case to determine whether
    [Montijo's] influence over" DPP "compromised the voluntariness of
    [her] behavior."        Houston, 857 F.3d at 435 (quoting U.S.S.G.
    § 2G1.3, cmt. n.3(B)).          As Montijo agrees, the court could "look
    to a variety of factors, including whether [the offender's conduct]
    displays an abuse of superior knowledge, influence and resources."
    United States v. Root, 
    296 F.3d 1222
    , 1234 (11th Cir. 2002).               When
    the alleged influencer is over ten years older than the victim, as
    here, there is a "rebuttable presumption" the enhancement applies.
    Houston, 857 F.3d at 434 (citing U.S.S.G. § 2G1.3, cmt. n.3(B)).
    In Houston, for example, we held the judge properly applied the
    increase when the defendant drove a 13-year-old girl between two
    states so his accomplice could prostitute her.              Id. at 435.     The
    district court found the defendant drove the minor "across state
    borders away from her family and familiar surroundings" to "various
    - 37 -
    locations to meet with adult" johns, "giving her few options other
    than engaging in prohibited sexual conduct."                Id.   In this case,
    taking cues from Houston, the trial judge applied the two-point
    bump under § 2G1.3 because Montijo drove DPP away from school to
    an unfamiliar motel and was "much older" than her.
    Montijo argues that we must find he rebutted the undue-
    influence presumption by showing that DPP (with CAP and Meléndez)
    planned    the    first    meeting   without    his    input      and   that   DPP
    "willing[ly]" had sex during the second one.            But even assuming he
    proved    those   facts,    the   judge   did   not   err    in    applying    the
    enhancement.      As in Houston, Montijo was well over ten years older
    than DPP, who needed her mom to drive her to middle school.                    He
    had the know-how and "resources," Root, 
    296 F.3d at 1234
    , to pick
    her up, drive the car, pay for the motel room, and drop the girls
    off before they were caught.         No, Montijo wasn't an interstate sex
    trafficker like Houston.          Montijo's few-hour excursions with DPP
    were shorter and arguably less coercive.              But § 2G1.3 turns on
    "undue influence," not coercion, and there was ample proof Montijo
    unduly influenced DPP from the beginning:             offered her "something
    to smoke or drink," brought her to a secluded motel where he
    flattered her "eyes" and "hair," gained her trust, followed up
    over KIK, and lured her again "from her family and familiar
    surroundings" to the same motel room where, alone with Montijo,
    she'd more likely agree to have sex.            Houston, 857 F.3d at 435;
    - 38 -
    see United States v. Lay, 
    583 F.3d 436
    , 445 (6th Cir. 2009)
    (upholding the enhancement when the "facts [were] consistent with
    a manipulative adult's building a relationship with a minor for
    the purpose of eventual sexual activity"). In these circumstances,
    the judge was well within his discretion to find that Montijo's
    influence "compromised the voluntariness of [DPP's] behavior" and
    to apply the increase.17
    As for Montijo's second claim — that he didn't use a
    computer to "entice" or "facilitate the travel of" DPP or KVM to
    have    unlawful     sex,   U.S.S.G.   §   2G1.3(b)(3)(A),   we've   already
    explained why it flops:         there was sufficient trial evidence to
    show that Montijo used KIK to entice DPP to come on the second
    trip.       As the government points out, the guideline goes beyond the
    17
    This case therefore differs from United States v. Calvo,
    
    596 Fed. Appx. 541
    , 543 (9th Cir. 2015), hammered by Montijo. In
    Calvo, there was unrebutted evidence the victim initiated pretty
    much everything — that she "willingly befriended Calvo,
    voluntarily engaged in sexual banter with him, requested that he
    pick her up, and willingly engaged in the sexual acts at issue"
    and "[t]here [was] simply no evidence that Calvo did or said
    anything to procure the victim's consent to conduct that she was
    not already inclined to do." 
    Id.
     In this case, there's no evidence
    DPP was the one who "requested" Montijo pick her up or that she
    was "already inclined" to have sex — if that matters, see 
    id. at 544
     (Christen, J., concurring in part and dissenting in part)
    (citing cases around the circuits holding that the minor's
    "willingness" does not bar an undue-influence finding); there's no
    evidence DPP "requested" that Montijo do anything or was willing
    to have sex with Montijo before he took her to a secluded motel
    and came on to her. Indeed, DPP did not agree to have sex until
    the second trip (if she did at all) — after Montijo spent six more
    days pursuing her on KIK.
    - 39 -
    four verbs in § 2422(b) to cover computer use that "facilitate[s]
    the travel of" minors for unlawful sex.   Id.   Since the evidence
    showed Montijo used KIK to plan the second outing with DPP and
    KVM, the judge appropriately applied the enhancement. See Houston,
    857 F.3d at 436 (affirming the district court's application of the
    enhancement because the defendant's accomplice used her smartphone
    to arrange sexual encounters between the victim and adult men).
    Lastly, Montijo faults the judge for the multiple-count
    adjustment. In his view, the judge should have grouped the three
    counts involving DPP (the enticement under § 2422(b) and the two
    transportation counts).   If he'd done that, there would have been
    fewer groups of offenses, and the multiple-count adjustment would
    have been three instead of four.
    The on-point guideline is § 3D1.2, which explains in the
    relevant snippet that "[c]ounts involve substantially the same
    harm within the meaning of this rule" and should be grouped
    (a) When counts involve the same victim and the
    same act or transaction[;]
    (b) When counts involve the same victim and two or
    more acts or transactions connected by a common
    criminal objective or constituting part of a common
    scheme or plan[; or]
    (c) When one of the counts embodies conduct that is
    treated as a specific offense characteristic in, or
    other adjustment to, the guideline applicable to
    another of the counts.
    U.S.S.G. 3D1.2.
    - 40 -
    Montijo does not dispute that each count involving a
    separate minor inflicted a "substantially" separate "harm" and
    deserved its own group.      U.S.S.G. § 3D1.2; see id. § 2G1.3, cmt.
    n.6.   That said, he argues that "all acts related to [DPP]
    encompassed one victim and one act (the transportation)" under
    prong (a), "or in the alternative, one victim and one common scheme
    (to meet with [DPP] at the motel)" under prong (b).             "[C]ounts
    that are part of a single course of conduct with a single criminal
    objective and represent essentially one composite harm to the same
    victim are to be grouped together, even if they constitute legally
    distinct offenses occurring at different times," he reminds us.
    U.S.S.G. § 3D1.2, cmt. n.4.       For example, a conspiracy to commit
    extortion and the extortion itself (though different offenses) are
    grouped — as are mail and wire fraud counts that were "each in
    furtherance of a single fraudulent scheme," "even if the mailings
    and telephone call occurred on different days."         Id.   But there's
    a flip side:     the guideline "does not" permit "the grouping of
    offenses" that do not reflect "one composite harm," such as
    "robbery   of   the   same   victim   on   different   occasions,"   which
    "involves multiple, separate instances of fear and risk of harm."
    Id. (noting that if "[t]he defendant is convicted of two counts of
    rape for raping the same person on different days" the counts
    should stay separate).

    Unlike an agreement to commit the same crime, or mails
    and wires sent to further the same scam, Montijo's two trips to
    the motel with DPP exposed her to two different sexually-charged
    encounters — away from familiar surroundings — to which she
    couldn't legally consent.         See United States v. Nagel, 
    835 F.3d 1371
    ,   1374   (11th   Cir.    2016)     (concluding   that    district    court
    properly refused to group two § 2422(b) counts because each "one
    of the[ ] sexual encounters with [the victim] — who was unable to
    consent due to her age — caused a separate harm"); United States
    v. Bivens, 
    811 F.3d 840
    , 843 (6th Cir. 2016) (holding that two
    instances of creating child pornography involving the same victims
    were separate because, in cases involving "sex crimes committed by
    the same defendant against the same victim over an extended period
    of time," "each act usually amounts to a fresh harm the victim
    must face anew"); see also United States v. Wise, 
    447 F.3d 440
    ,
    447 (5th Cir. 2006) (holding court rightly refused to group counts
    based on separate explicit photos defendant solicited from child
    on separate days).      And Montijo "had two separate objectives, to
    have sexual relations with [DPP] two separate times," Nagel, 835
    F.3d at 1375 — even if he didn't succeed on the first drive.                 So
    the judge did not err in treating the two transporting-DPP counts
    separately.
    Given   that       outcome,    any   mistake   in    grouping     the
    enticement and day-two transportation count was harmless.                 If the
    - 42 -
    judge had treated those counts as separate offenses, he would have
    only decreased the number of "units" for the multiple-count-
    adjustment by one (to 3.5), meaning the four-point enhancement
    would still have applied.    See U.S.S.G. § 3D1.4 (equating 3.5–5
    units with a four-level increase).        All told, then, the judge
    rightly assessed the disputed enhancements and correctly computed
    the guideline range of 235–293 months in prison. See United States
    v. Hinkley, 
    803 F.3d 85
    , 93 (1st Cir. 2015) (noting that a mistake
    in applying the Guidelines is ordinarily harmless if it does not
    change the guideline range).
    Substantive Reasonableness
    Unable to show nonharmless procedural error, Montijo
    urges that his 198-month sentence — a 37-month downward variance
    — was still unreasonably high.   In doing so, he fights an "uphill"
    battle: we have to affirm so long as the judge gave "'a plausible
    explanation' for the selected sentence and 'reached a defensible
    result.'"    United States v. Dávila-Bonilla, 
    968 F.3d 1
    , 12 (1st
    Cir. 2020) (first quoting United States v. Vixamar, 
    679 F.3d 22
    ,
    29 (1st Cir. 2012), then quoting United States v. Chisholm, 
    940 F.3d 119
    , 132 (1st Cir. 2019)).         We'll overturn a sentence as
    substantively unreasonable only if it goes beyond the "expansive
    universe of reasonable sentences.'"       United States v. King, 
    741 F.3d 305
    , 308 (1st Cir. 2014).   "When, as in this case, a district
    court essays a substantial downward variance from a properly
    - 43 -
    calculated guideline sentencing range, a defendant's claim of
    substantive unreasonableness will generally fail."           United States
    v. Floyd, 
    740 F.3d 22
    , 39–40 (1st Cir. 2014).
    Montijo    argues    that   this   case    is   the   "long-odds
    exception" — the "rare below-the-range sentence" that remains
    unreasonably harsh.    King, 741 F.3d at 310.        He stresses that he'd
    "never had a brush with law enforcement" and had supportive family
    and a "promising future" — factors that warranted no more than a
    120-month sentence.      But the district judge considered those
    positives: he noted in court that Montijo had a university degree,
    was gainfully employed, and "was raised in a pro-social environment
    with the support of his parents who worked tirelessly to provide
    for their children."    And he heard defense counsel's reminder that
    Montijo's family was there at sentencing and "all" the previous
    hearings, and that "having a family to return to after" prison
    bodes "well for positive rehabilitation upon release." See Dávila-
    Bonilla, 968 F.3d at 12 (explaining that "we can infer that the
    district   judge   considered   a    defendant's   sentencing    claims   by
    comparing what the parties argued and what was in the presentence
    report with what the judge did").        That the judge varied downward
    by 37 months confirms that he weighed those points heavily.               But
    he also considered Montijo's "repeat" conduct (on two separate
    days) and the "impact" it had on DPP and her family. And in doing
    so, he found that a 198-month sentence was needed to "reflect[ ]
    - 44 -
    the seriousness of the offense," "promote[ ] respect for the law,"
    and ensure adequate "deterrence and punishment" — factors the law
    directed him to consider.   Though the judge gave less weight to
    the "mitigating factors" than Montijo "thinks they deserved,"
    Dávila-Bonilla, 968 F.3d at 12 (quoting Clogston, 662 F.3d at 593),
    the reasons the judge outlined were "fully sufficient to justify"
    Montijo's substantially-below-guideline sentence.   King, 741 F.3d
    at 310.
    END
    So, our careful review complete, we affirm Montijo's
    convictions and sentence.
