    APPEAL FROM THE UNITED STATES DISTRICT COURT

    Before
    Torruella, Thompson, and Barron,
    Circuit Judges.

    appellant.

    February 14, 2020
    BARRON, Circuit Judge.     This appeal concerns a suit by
    Kevin C. Robinson that arises from the events that led to his
    retirement from his position as Fire Chief for the Fire Department
    ("Department") of the Town of Marshfield, Massachusetts ("the
    Town").    The District Court granted summary judgment against
    Robinson on each of his claims, which alleged violations of both
    federal and state law, and Robinson now appeals from that ruling.
    We affirm the grant of summary judgment on Robinson's federal-law
    claims, which he brings under the Age Discrimination and Employment
    Act ("ADEA"), 
    29 U.S.C. §§ 621-634.1
           With respect to the state-
    law claims, which the District Court had jurisdiction over pursuant
    to 
    28 U.S.C. § 1367
    , we affirm the District Court's grant of
    summary   judgment   against   Robinson   as    to   his   claims   for   age
    discrimination, retaliation based on his 2015 complaint of age
    discrimination, and failure to investigate.           We vacate, however,
    the District Court's grant of summary judgment against Robinson as
    to his state-law claims for retaliation based on his 2014 complaint
    of   gender   discrimination,    breach    of    contract,     intentional
    interference with contractual relations, and defamation, and we
    direct the dismissal of these claims without prejudice.
    1On appeal, Robinson challenges the grant of summary judgment
    against him as to these claims only insofar as they named the Town
    as the defendant.

    I.
    Robinson retired from his position as Fire Chief in March
    of 2015 when he was sixty years old after having worked with the
    Department since 1978.2           He did so following a dispute with the
    Town that concerned, at least in part, the Town's allegations that
    Robinson    had    engaged   in    conduct       that   violated    Massachusetts'
    conflict of interest laws while serving as Fire Chief, due to his
    interactions with various members of his family whom he had either
    worked with or managed at the Department.                See Mass. Gen. Laws ch.
    268A, §§ 1-29.
    In the course of the dispute of Robinson's failure to
    comply with those laws, the Town retained a law firm to investigate
    the matter.       The law firm's investigation led it to issue a report
    that concluded that the evidence could support a finding that
    Robinson had committed numerous violations of those laws.                        The
    report     recommended    that     the    Town     refer   the     matter   to   the
    Massachusetts State Ethics Commission.
    Robinson announced his retirement in the wake of the
    issuance of the law firm's report.               He then filed a timely charge
    of   "discrimination      based     on    age     and   retaliation"    with     the
    Massachusetts Commission Against Discrimination and the United
    2We recite the relevant facts in the light most favorable to
    Robinson, the nonmoving party. See Santangelo v. N.Y. Life Ins.

    States    Equal     Employment      Opportunity    Commission     ("EEOC")      and
    received a Right to Sue Letter from the EEOC.
    In December of 2016, Robinson filed a complaint in the
    United States District Court for the District of Massachusetts
    against the Town and other defendants that alleged various federal-
    law and state-law claims, including the ones that are before us on
    appeal.    The defendants moved for summary judgment as to all of
    Robinson's claims, and the District Court granted that motion.
    Robinson now appeals from the judgment dismissing his claims.

    "We   review    the    District     Court's     grant    of    summary
    judgment de novo."      Santangelo v. N.Y. Life Ins. Co., 
    785 F.3d 65
    ,
    68 (1st Cir. 2015).      We may affirm a grant of summary judgment "on
    any ground revealed by the record."

    Coal v. Town of Houlton,

    Summary judgment is appropriate if the record, viewed in
    the   light     most   favorable      to    the   nonmoving    party    --    here,
    Robinson -- discloses "no genuine issue of material fact" and thus
    "demonstrates that 'the moving party is entitled to a judgment as
    a matter of law.'"           Iverson v. City of Boston, 
    452 F.3d 94
    , 98
    (1st Cir. 2006) (quoting Fed. R. Civ. P. 56(c)).                  The nonmoving
    party may "defeat a summary judgment motion by demonstrating,
    through submissions of evidentiary quality, that a trialworthy
    issue persists."       
    Id.

    III.
    We   begin   with   Robinson's     challenge   to   the   District
    Court's grant of summary judgment to the Town as to the ADEA claim
    that he brings under 
    29 U.S.C. § 623
    (a)(1).           That provision makes
    it "unlawful for an employer . . . to discharge any individual or
    otherwise discriminate against any individual with respect to his
    compensation, terms, conditions, or privileges of employment,
    because   of    such   individual's   age."      
    29 U.S.C. § 623
    (a)(1).
    Robinson alleges in this claim that the Town took actions against
    him based on his age that, by creating a hostile work environment,
    caused his constructive discharge, notwithstanding that he, at
    least formally, left the Department by retiring.
    We follow the parties and the District Court in analyzing
    the District Court's grant of summary judgment to the Town on this
    claim pursuant to the burden-shifting framework that the Supreme
    Court set forth in McDonnell Douglas Corp. v. Green, 
    411 U.S. 792
    (1973).   See Santangelo, 785 F.3d at 69-71 (assessing whether the
    plaintiff's ADEA claim for discrimination in employment survives
    summary judgment under the McDonnell Douglas framework).3                That
    3 Although the Supreme Court "has not definitively decided
    whether the evidentiary framework of [McDonnell Douglas] utilized
    in Title VII cases is appropriate in the ADEA context,"
    Soto-Feliciano v. Villa Cofresí Hotels, Inc., 
    779 F.3d 19
    , 23 (1st
    Cir. 2015) (citing Gross v. FBL Fin. Servs., Inc., 
    557 U.S. 167
    ,
    175 n.2 (2009)), this Circuit "has long applied the McDonnell
    Douglas framework to ADEA cases," 
    id.
     (quoting Vélez v. Thermo
    King de P.R., Inc., 
    585 F.3d 441
    , 447 n.2 (1st Cir. 2009)).
    - 5 -
    framework requires the plaintiff, to survive summary judgment,
    first to provide evidence sufficient to permit a reasonable juror
    to find that a prima facie case of age discrimination under the
    ADEA has been established.       See Del Valle-Santana v. Servicios
    Legales de P.R., Inc., 
    804 F.3d 127
    , 129-30 (1st Cir. 2015).            To
    meet that burden, the plaintiff must provide evidence from which
    a reasonable juror could find that:        (1) he was at least forty
    years old; (2) his work was sufficient to meet his employer's
    legitimate expectations; (3) his employer took adverse action
    against him; and, depending on the alleged adverse action, (4) the
    employer refilled the position, thus demonstrating a continuing
    need for the plaintiff's services and skill.           See id.; see also
    Vélez    v. Thermo King de Puerto Rico, Inc., 
    585 F.3d 441
    , 447 (1st
    Cir. 2009).
    In the event that the plaintiff provides evidence that
    would permit a reasonable juror to find that he has made out the
    requisite prima facie case, "[t]he burden of production then shifts
    to the employer 'to articulate a legitimate, non-discriminatory
    reason for its decisions.'"        Vélez, 
    585 F.3d at 447
     (quoting
    Arroyo-Audifred v. Verizon Wireless, Inc., 
    527 F.3d 215
    , 219 (1st
    Cir.    2008)).   If   the   employer   meets   that   burden,   then   the
    plaintiff, to survive summary judgment, must provide evidence from
    which a reasonable juror could find that "the employer's proffered
    - 6 -
    reason is actually a pretext for discrimination."             Mesnick v. Gen.
    Elec. Co., 
    950 F.2d 816
    , 823 (1st Cir. 1991).
    To satisfy this burden with respect to pretext, the
    plaintiff must "elucidate specific facts which would enable a jury
    to find that the reason given" by the defendant for the adverse
    employment action "is not only a sham, but a sham intended to cover
    up the employer's real motive:               age discrimination."          Soto-
    Feliciano, 779 F.3d at 25 (quoting Mesnick, 
    950 F.2d at 824
    ).                At
    this stage of the analysis, the "'focus must be on the perception
    of the decisionmaker,' that is, whether the employer believed its
    stated reason to be credible."         Mesnick, 
    950 F.2d at 824
     (quoting
    Gray v. New Eng. Tel. & Tel. Co., 
    792 F.2d 251
    , 256 (1st Cir.
    1986)).
    We may assume that -- despite the District Court's
    contrary ruling -- the record would permit a reasonable juror to
    find   that   Robinson   made    out     a    prima   facie    case   of     age
    discrimination in employment, including that he demonstrated that
    there is a genuine issue of triable fact as to whether he was
    constructively discharged.      The reason we may do so is that, as we
    will explain, Robinson has failed to identify evidence in the
    record from which a reasonable juror could find that the Town's
    asserted legitimate, nondiscriminatory reason for acting toward
    him as it did was a pretext for age discrimination.
    - 7 -
    The Town asserts that it acted as it did in part due to
    its concerns about Robinson's performance as Fire Chief, which
    included concerns about his management style and morale issues
    within the Department.   Robinson refers in his recitation of the
    facts in his brief to us that he received a positive performance
    review in 2012 -- and thus years before his retirement -- from the
    Town Administrator, Rocco Longo.    He also refers in that portion
    of his brief to the fact that he had received no other reviews in
    the years since.   But, Robinson fails to develop an argument as to
    why the evidence in the record that supports those particular
    assertions regarding his past performance reviews -- or any other
    evidence in the record -- suffices to permit him to meet his burden
    at this stage of the litigation to show that the Town's asserted
    concerns about his performance as Fire Chief were pretextual.
    Instead, Robinson focuses his attention on the other reason that
    the Town asserted for having acted toward him as it did, which is
    that the Town was concerned that he had violated the state's
    conflict of interest laws while serving as Fire Chief.
    We assume that Robinson's choice to focus only on that
    latter asserted reason by the Town does not doom his challenge to
    the grant of summary judgment, and, we note, the Town does not
    argue that it does.    But, even on that assumption, he still, to
    survive summary judgment, must satisfy his burden to show that the
    evidence creates a genuine issue of disputed fact as to pretext
    - 8 -
    with respect to the Town's asserted concerns about his violation
    of those conflict of interest laws.          And, we will explain, he has
    not done so.
    In challenging as pretextual this asserted reason for
    the Town's actions toward him, Robinson argues that the record
    suffices to permit a reasonable juror to find that he had complied
    with the state's conflict of interest laws that the law firm's
    report addresses.     But, with respect to pretext, the question is
    "whether the employer believed its stated reason to be credible,"
    
    id.
     (citing Gray, 
    792 F.2d at 256
    ), not whether Robinson in fact
    violated the state's conflict of interest laws.            See Ronda-Perez
    v. Banco Bilbao Vizcaya Argentaria-P.R., 
    404 F.3d 42
    , 45 (1st Cir.
    2005) (explaining that the plaintiff must show that his termination
    was something more than an "unusual act" or a "business error,"
    and that "'pretext' means deceit used to cover one's tracks").
    Thus, this aspect of Robinson's challenge to the grant of summary
    judgment against him on this ADEA claim is not persuasive.
    We   move   on,   then,    to     consider   Robinson's   apparent
    contention -- though cursorily made -- that there is a genuine
    issue of triable fact as to pretext due to the way that the law
    firm conducted its investigation into his possible violation of
    the state's conflict of interest laws, on which its report finding
    evidence of such violations was based.          Robinson is right that an
    employer may be deemed to have acted pretextually if it relies for
    - 9 -
    its     actions    toward     an     employee    on    the     conclusions      of   an
    investigation that the employer knows to have been a sham.                           See
    Vélez, 
    585 F.3d at
    450 n.4 (analyzing record evidence to determine
    whether an investigation was a sham).                 But, we are not persuaded
    by Robinson's arguments (to the extent that he develops them) that
    the record, considered as a whole, provides a supportable basis
    from which a reasonable juror could find that the law firm's
    investigation lacked integrity, let alone that the Town knew that
    it did.
    Robinson first focuses on the fact that the record
    supportably       shows      that    the   law    firm       that    conducted       the
    investigation did not interview him.              The undisputed record shows,
    however, that the law firm did not interview Robinson due to a
    combination       of     factors    that   included      the    unavailability        of
    Robinson's        attorney     for     a   month-long        period       during     the
    investigation into his conduct and Robinson's departure from a
    scheduled interview after the law firm had declined to authorize
    him to record the interview.           Thus, there is no basis in the record
    from which a reasonable juror could find that the law firm was not
    interested in obtaining Robinson's side of the story, let alone
    that the Town knew that it was not.              See Riggs v. AirTran Airways,
    Inc., 
    497 F.3d 1108
    , 1119 (10th Cir. 2007).
    Robinson also calls attention to the fact that the record
    shows    that     Town    officials     were    involved       in   the   law   firm's
    - 10 -
    investigation.     The record reveals, in this regard, that, prior to
    reviewing a draft of the law firm's report, Town officials provided
    copies of Robinson's contract and the Town's Charter provisions
    referenced in the contract's section on termination for good cause
    to the law firm.    The record further reveals that, after reviewing
    a draft of the law firm's report, Town officials corrected a
    reference in that draft to who had served as Captain in the
    Department at a particular time, requested that the conclusions in
    the report be framed as opinions, and instructed that the report
    could include "may" or "appear" if the investigators were "not
    sure" about any conclusions.
    But, we are aware of no authority that indicates that
    limited involvement by Town officials of that sort -- none of which
    even arguably took the form of directing the law firm to reach
    conclusions that its findings could not support -- would suffice
    to permit a reasonable juror to find that the investigation was
    rigged and that the Town knew it.        Nor does Robinson purport to
    identify any such precedent or point to any evidence in the record
    to show that such involvement by Town officials -- or any of their
    other actions related to the law firm's investigation -- violated
    any written or unwritten policies or regulations for conducting
    such an investigation.       See, e.g., Kendrick v. Penske Transp.
    Servs., Inc., 
    220 F.3d 1220
    , 1230 (10th Cir. 2000) (noting the
    relevance in the pretext analysis of evidence that the "defendant
    - 11 -
    acted contrary to an unwritten policy or contrary to company
    practice when making the adverse employment decision").
    We   recognize   that,   as   Robinson   points   out,    the
    undisputed record shows that the defendants offered to help the
    law firm "wade through" documents in preparing its report.         But,
    the record does not provide support for a reasonable juror to find,
    based on the evidence in the record of that offer or based on any
    other evidence in the record, that the law firm's conclusions in
    the report were based on records that the defendants cherry-picked.
    Finally, Robinson asserts that the record shows that the
    law firm did not ask questions about whether he favored one family
    member who worked in the Department, his niece, even though the
    law firm's report concluded that the evidence could support a
    finding that he had used his position to secure unwarranted
    privileges or exemptions for her that were not available to
    similarly situated individuals.     Robinson notes, too, that the
    lawyer who oversaw the investigation for the law firm stated in
    his deposition that he could not make a determination of favoritism
    without knowing how the Fire Chief treated individuals outside of
    his family.
    But, even if a reasonable juror could find that the law
    firm erred by not asking the right questions to support one of its
    numerous findings that Robinson had committed conflict of interest
    violations, Robinson points to no evidence that indicates that the
    - 12 -
    Town knew that the law firm may have erred in this way.                      Nor does
    he point to any evidence that the law firm lacked sufficient
    evidence to support the other findings in the report, which
    concluded     that    Robinson's      involvement       in    employment      matters
    related to his family in and of itself could have constituted a
    violation of the state's conflict of interest laws.                      Nor, finally,
    is it so clear that the conflict of interest laws permitted such
    involvement     by    him     in   personnel    matters      that    a    juror   could
    reasonably find that the Town could not have relied on the report's
    findings in that regard other than as a pretext for discrimination.
    Robinson does also suggest at one point in his brief
    that there is evidence from which a reasonable juror could find
    that   the    Town    acted    with   age-based    discriminatory           animus   in
    consequence of evidence in the record that could support a finding
    that Town officials had made repeated suggestions that he retire.
    The evidence reveals that two of those suggestions were made prior
    to   the     Town    having    retained   the     law     firm      to   conduct     the
    investigation into his potential violation of the conflict of
    interest laws and that the third suggestion was made while that
    investigation was ongoing and thus before the law firm issued the
    report with its findings.
    There is no evidence in the record to suggest, however,
    that the law firm was aware that the suggestions for him to retire
    were made prior to the initiation of the investigation or issuance
    - 13 -
    of the report.   Thus, we do not see how the evidence that those
    suggestions were made to Robinson creates a genuine issue of
    material fact as to whether the Town's asserted concerns about his
    violation of the state's conflict of interest laws were merely a
    pretext for discrimination.   By Robinson's own account, the Town
    had not taken actions sufficient to result in his constructive
    discharge until after the law firm's report had issued.   There is,
    accordingly, no basis in the record for a juror reasonably to
    conclude that the Town responded as it did to the findings by the
    law firm -- which, as we have explained, Robinson fails to show
    were the product of a sham investigation -- out of age-based animus
    rather than, as the Town asserts, a concern about what they showed
    about Robinson's conduct in office.4
    Thus, even considering the record as a whole, we do not
    see how it suffices to permit a reasonable juror to find that the
    investigation into Robinson's compliance with the state's conflict
    of interest laws was a sham or that the Town relied on a report by
    4  Robinson separately asserts, apparently pursuant to
    Massachusetts General Laws Chapter 151B, that he was impermissibly
    retaliated against by the defendants for having reported in 2014
    -- and thus before the initiation of the law firm's investigation
    into his violation of the state's conflict of interest laws --
    that his niece had been subjected to gender-based discrimination
    while an employee of the Department.      But, Robinson does not
    develop any argument that the fact that the law firm's
    investigation into his possible violation of those laws commenced
    thereafter itself calls into question the integrity of the
    investigation or of the report that the law firm issued based on
    that investigation.
    - 14 -
    that law firm that it knew to be a sham.   Accordingly, Robinson's
    attempt to satisfy his burden with respect to pretext by casting
    doubt on the integrity of the law firm's investigation and report
    fails.
    Robinson also tries to make the case for meeting his
    burden as to pretext in another way. He argues that the undisputed
    record shows that the Town replaced him, following his retirement,
    with a younger, less-qualified employee, who received higher pay,
    and that the circumstances of his replacement show that the Town's
    claimed reliance on his misconduct for the various adverse actions
    that Robinson alleges that it took against him was a pretext for
    age discrimination.
    Robinson points out that the undisputed record shows
    that he had a Bachelor of Science in Fire Administration; thirteen
    years of experience at the Department, during which time he had
    served as the Fire Chief, a fire officer, and an inspector; and
    Emergency Medical Technician certifications.     By contrast, he
    rightly asserts, the undisputed record shows that the person who
    replaced him as the Fire Chief following his retirement was about
    ten years younger, was licensed only as an Emergency Medical
    Technician, did not have a fire officer or inspector license, and
    became credentialed as a fire chief only once he had obtained the
    - 15 -
    position for the Town.5      In addition, Robinson asserts that the
    evidence, when viewed in the light most favorable to him, indicates
    that the Town changed the job qualifications for Fire Chief from
    having a master's degree when Robinson was hired to requiring only
    a high school diploma when his replacement was hired.
    But, "[q]ualifications are notoriously hard to judge"
    and proving pretext through relative qualifications is an "uphill
    struggle" for the plaintiff.      Rathbun v. Autozone, Inc., 
    361 F.3d 62
    , 74 (1st Cir. 2004).    Thus, "in the absence of strong objective
    evidence (e.g., test scores), proof of competing qualifications
    will seldom, in and of itself, be sufficient to create a triable
    issue    of   pretext."   
    Id.
       (requiring   a   "stark"   difference   in
    qualifications, 
    id. at 75
    ).       Given that the record provides no
    basis for a reasonable juror to find that the law firm's report
    identifying his possible violations of the state's conflict of
    interest laws was a sham, we fail to see how the evidence in the
    record that would permit a reasonable juror to find that the person
    who replaced Robinson as Fire Chief had fewer qualifications for
    that post when he assumed the position than Robinson had at the
    time that he left it would also permit a reasonable juror to find
    5 Robinson also asserts in his Rule 56.1 motion and on appeal
    that his replacement's highest degree was a high school diploma,
    but he does not point to evidence in the record to support this
    contention.
    - 16 -
    that the Town's asserted legitimate, nondiscriminatory reason for
    its alleged constructive discharge of him was pretextual.
    We note, too, that even if Robinson were right that the
    record suffices to support a finding that the Town changed the
    qualifications after he retired to no longer require the Fire Chief
    to have a master's degree, the undisputed record shows that
    Robinson himself did not have such a degree when he was named the
    Fire Chief.      Thus, this aspect of the record cannot support
    Robinson's    contention   that   the   Town's   alleged   change   in   the
    qualifications supports an inference of pretext.
    Robinson's last ground for challenging the grant of
    summary judgment against him on this ADEA claim appears to be that
    the record shows that the Town had decided to terminate his
    employment by the time that he retired.           We may assume that the
    record would permit a reasonable juror to find that Robinson was
    constructively discharged and thus that he did not terminate his
    employment voluntarily when he retired.          But, the evidence in the
    record that would suffice to support that finding does not suffice
    to create a genuine issue of triable fact as to whether the Town's
    asserted reason for acting toward him as it did was a pretext for
    discriminating against him based on his age.          Thus, the evidence
    that Robinson highlights to show that the Town wanted to terminate
    him at the time that he retired -- evidence that includes earlier
    suggestions by Town officials that he retire -- fails to support
    - 17 -
    his challenge to this aspect of the grant of summary judgment
    against him.     For this reason, too, therefore, his challenge to
    the grant of summary judgment to the Town on this claim fails.
    IV.
    Robinson separately claims that, in violation of the
    ADEA, the Town fired him in retaliation for his efforts to address
    the age discrimination to which he contends that he was subject.
    See 
    29 U.S.C. §§ 623
    (a),(d).         Like the District Court, we follow
    the McDonnell Douglas framework in analyzing whether this claim
    survives summary judgment, "albeit with slight modifications to
    account   for   the    retaliation    claim's       distinct    focus."   Soto-
    Feliciano, 779 F.3d at 30 (quoting Mesnick, 
    950 F.2d at 827
    ).
    Under      that   framework,     the    first   stage   requires   the
    plaintiff to "make a prima facie showing that (i) he engaged in
    ADEA-protected conduct, (ii) he was thereafter subjected to an
    adverse employment action, and (iii) a causal connection existed
    between the protected conduct and the adverse action."                        
    Id.
    (quoting Mesnick, 
    950 F.2d at 827
    ).               If the plaintiff makes this
    prima facie showing, the burden shifts to the defendant to, as in
    the discrimination context, "offer a legitimate, non-retaliatory
    reason for the adverse employment action."             
    Id.
         Finally, to rebut
    this showing, "the plaintiff must assume the further burden of
    showing that the proffered reason is a pretext calculated to mask
    retaliation."      Id. at 30-31 (quoting Harrington v. Aggregate
    - 18 -
    Indus.-Ne. Region, Inc., 
    668 F.3d 25
    , 31 (1st Cir. 2012)).            The
    plaintiff then must show, in order to fend off a grant of summary
    judgment against him, "more than that the defendants' asserted
    reason for taking adverse action against him was not the real
    reason.   He must show that the reason given was a cover for
    retaliation."    
    Id. at 32
    .
    Robinson predicates this retaliation claim on the formal
    complaint of age discrimination that he filed with the Town's Board
    of Selectmen in January of 2015.           He alleges that, due to this
    complaint, he suffered an array of retaliatory actions between
    January and March of 2015, which together created the hostile work
    environment that he alleges caused his constructive discharge.
    Under the applicable burden-shifting framework, to get
    past summary judgment on this claim, Robinson must show that there
    is a genuine issue of disputed fact as to the causal connection
    between his protected conduct and the Town's alleged retaliation.
    To make that causal connection, Robinson relies on the fact that
    the record shows that, after his filing of the January 2015
    complaint, the Board met and voted to terminate him, he was placed
    on paid leave, and he was called to a show cause hearing.
    A very close temporal proximity between an employer's
    knowledge of a protected activity and an adverse action can suffice
    to   support    an    inference   of   a   causal   connection   in   some
    circumstances.       See, e.g., Calero-Cerezo v. U.S. Dep't of Justice,
    - 19 -
    
    355 F.3d 6
    , 25 (1st Cir. 2004); Mesnick, 
    950 F.2d at 828
    .                         But, a
    reasonable juror could not, on this record, find based on timing
    alone that there was a causal connection between Robinson's January
    2015 complaint and any adverse actions that followed.
    As we have noted, the Town asserts that it acted as it
    did toward Robinson, in significant part, due to concerns about
    his compliance with the state's conflict of interest laws for which
    the law firm's investigation provided support.                         The undisputed
    record shows, however, that the Town had hired the law firm to
    conduct its investigation into Robinson's compliance with those
    laws       before    he    had   filed   his    January    2015    complaint.        The
    undisputed record further shows that the law firm issued the report
    that concluded that the evidence sufficed to support a finding
    that       Robinson       had    violated    the     conflict     of   interest     laws
    immediately before the Town took the alleged adverse actions that
    ground his retaliation claim. In addition, Robinson fails to point
    to any evidence that the law firm that conducted the investigation
    knew       about    his    January   2015     complaint,    either     while   it   was
    conducting its investigation or while it was preparing the report.6
    6
    As we have noted, see supra text accompanying note 4,
    Robinson does also allege a claim of retaliation under
    Massachusetts General Laws Chapter 151B based on his 2014 report
    that his niece had been subjected to gender-based discrimination
    while working at the Department.     But, as we have also noted,
    Robinson does not contend that the law firm's investigation of his
    possible violation of the conflict of interest laws was a sham
    - 20 -
    Thus, given the intervening event of the report's issuance, we
    reject Robinson's attempt to meet his burden as to pretext based
    on timing alone.         See Twigg v. Hawker Beechcraft Corp., 
    659 F.3d 987
    , 1001-02 (10th Cir. 2011) (finding, in analyzing a 
    42 U.S.C. § 1981
     retaliation claim under the McDonnell Douglas framework,
    that       intervening   events   undermined   the   plaintiff's   temporal
    proximity argument); see also Clark Cty. Sch. Dist. v. Breeden,
    
    532 U.S. 268
    , 272 (2001) (per curiam) (noting that an employer
    "need not suspend previously planned [actions] upon discovering
    that a [discrimination] suit has been filed, and their proceeding
    along lines previously contemplated, though not yet definitively
    determined, is no evidence whatever of causality").7
    because it followed his having made that report of gender-based
    discrimination.
    7
    Robinson also claims that the Town violated the ADEA by
    failing to investigate and remedy the discrimination against him.
    Robinson first raised arguments on appeal about his failure to
    investigate claim under the ADEA in his reply brief, after stating
    in his opening brief, "Plaintiff is not appealing the dismissal"
    of his failure to investigate claim.      Thus, he has waived his
    challenge to the District Court's ruling that there is no
    affirmative duty to investigate under the ADEA unless Robinson
    proves his discrimination claim or the Secretary of Labor brings
    the suit on behalf of the employee. See Moffat v. U.S. Dep't of
    Justice, 
    716 F.3d 244
    , 255 (1st Cir. 2013) (citing N. Am. Specialty
    Ins. Co. v. Lapalme, 
    258 F.3d 35
    , 45 (1st Cir. 2001) ("There are
    few principles more securely settled in this court than the
    principle which holds that, absent exceptional circumstances, an
    appellant cannot raise an argument for the first time in a reply
    brief.")).
    - 21 -
    V.
    We turn, then, to the District Court's grant of summary
    judgment to the defendants on Robinson's state-law claims.    As we
    mentioned at the outset, the District Court had jurisdiction over
    these claims solely pursuant to its supplemental jurisdiction.
    See 
    28 U.S.C. § 1367
    .      That raises the question of whether we
    should address their merits or direct their dismissal without
    prejudice in the interests of comity.     See Wilber v. Curtis, 
    872 F.3d 15
    , 22-23 (1st Cir. 2017). We review for abuse of discretion.
    
    Id. at 23
    .
    Notwithstanding that the federal-law claims have been
    dismissed, we may affirm the portions of a grant of summary
    judgment on remaining state-law claims "that are so plainly correct
    that no substantial question of state law is presented," 
    id.,
     as
    this course best serves "the interests of fairness, judicial
    economy, convenience, and comity," 
    id.
     (quoting Desjardins v.
    Willard, 
    777 F.3d 43
    , 45-46 (1st Cir. 2015)).    Thus, we affirm the
    District Court's grant of summary judgment to the defendants on
    Robinson's state-law claim for age discrimination in employment
    under Massachusetts General Laws Chapter 151B     ("Chapter 151B"),
    given our conclusion with respect to Robinson's ADEA claim for age
    discrimination in employment that he has not provided evidence
    that would permit a reasonable juror to find that the defendants'
    legitimate, nondiscriminatory reason was pretextual.     See Bulwer
    - 22 -
    v.   Mount   Auburn   Hosp.,   
    46 N.E.3d 24
    ,    32-33    (Mass.    2016).
    Similarly, we affirm the District Court's grant of summary judgment
    to the defendants on Robinson's state-law claim for retaliation
    based on his attempt to redress the alleged age discrimination
    under   Chapter   151B,   given   our   conclusion    in     connection   with
    Robinson's ADEA claim for retaliation that timing alone does not
    support a finding of a causal connection between his January 2015
    complaint for age discrimination and the actions taken against him
    that he contends resulted in his constructive discharge.               See Psy-
    Ed Corp. v. Klein, 
    947 N.E.2d 520
    , 530 (Mass. 2011) (citing federal
    case law that analyzes retaliation claims brought under the ADEA
    and explaining that a causal connection may be inferred based on
    temporal proximity, but that the plaintiff must still show that
    "the employer's desire to retaliate against the employee" was "a
    determinative factor in its decision to take adverse action"); see
    also Mole v. Univ. of Mass., 
    814 N.E.2d 329
    , 341 (Mass. 2004).              We
    affirm, too, the District Court's grant of summary judgment to the
    Town on his state-law claim under Chapter 151B for failure to
    investigate, as the same reasons that lead us conclude that
    Robinson has waived any challenge to the District Court's grant of
    summary judgment to the Town on his federal-law claim under the
    ADEA for failure to investigate lead us to conclude that he has
    - 23 -
    waived any challenge to the grant of summary judgment on the state-
    law variant of it that he brings.
    That still leaves for us to address the District Court's
    grant of summary judgment against Robinson as to the various state
    common-law claims that he brings, which are for breach of contract,
    intentional     interference      with    contractual     relations,      and
    defamation, as well as his Chapter 151B claim for retaliation based
    on his reporting of gender discrimination.             Robinson challenges
    those portions of the summary judgment ruling on various grounds
    that the defendants vigorously contest.          But, because "[n]eedless
    decisions of state law should be avoided both as a matter of comity
    and to promote justice between the parties, by procuring for them
    a surer-footed reading of applicable law," United Mine Workers of
    Am. v. Gibbs, 
    383 U.S. 715
    , 726 (1966), we follow a different
    course with respect to these claims than we have taken with respect
    to the other state-law claims that are before us.
    There is no analogue to any of these three state common-
    law claims in the federal-law claims that we have addressed.              Nor
    does our analysis of Robinson's ADEA retaliation claim, which is
    predicated on protected conduct by him that occurred in January of
    2015 (and thus once the law firm's investigation into his potential
    violation of the state's conflict of interest laws was already
    underway) necessarily bear on the issues presented by his Chapter
    151B   claim   of   retaliation   based    on   his   reporting   of   gender
    - 24 -
    discrimination in January of 2014 (which preceded the law firm's
    investigation).   Thus, rather than attempt to resolve the state-
    law issues that are in dispute between the parties as to these
    claims, we direct their dismissal without prejudice.
    VI.
    We affirm the District Court's grant of summary judgment
    on Robinson's federal-law claims under the ADEA, and on the state-
    law claims for discrimination, retaliation based on the 2015
    complaint of age discrimination, and failure to investigate.8   We
    8 We note that, after Robinson filed this appeal, one of the
    defendants named in some of the state-law claims that he
    brings -- Rocco Longo -- passed away.     Because Robinson brings
    each of the state-law claims before us against at least one
    defendant other than Longo, his appeal of the grant of summary
    judgment on these claims is not moot.       Moreover, pursuant to
    Federal Rule of Appellate Procedure 43, this Court granted
    Robinson's motion to substitute Michael A. Maresco, the Town
    Administrator, as a defendant in place of Longo for all claims
    asserted against Longo in his official capacity.
    Robinson also moved to substitute Longo's estate as the
    defendant in place of Longo for all claims asserted against Longo
    in his personal capacity, and, in response, we ordered the
    defendants to file a status report advising the Court of their
    efforts to find a personal representative of Longo who could be
    substituted as a party on appeal under Federal Rule of Appellate
    Procedure 43(a). The defendants filed a status report in which
    they explained that no one had been appointed as the personal
    representative of Longo's estate, and, as of the time of this
    opinion's publication, neither party has identified a personal
    representative to be substituted for Longo as the defendant for
    any claims that Robinson brings against Longo in his personal
    capacity. The defendants now argue to us that, to the extent a
    defamation claim was brought against Longo in his personal
    capacity, it does not survive his death. Robinson does not address
    this contention in his briefing to us, and we thus treat as moot
    Robinson's appeal of the grant of summary judgment of that state-
    - 25 -
    vacate the District Court's grant of summary judgment on the state-
    law claims for retaliation based on Robinson's 2014 report of
    gender   discrimination,    breach     of   contract,   intentional
    interference with contractual relations, and defamation, and we
    direct the dismissal of these claims without prejudice.   No costs
    are awarded.
    law claim, to the extent that Robinson brings it against Longo in
    his personal capacity, just as we treat as moot Robinson's appeal
    of the grant of summary judgment of any other of Robinson's state-
    law claims that are before us on appeal to the extent that they,
    too, are brought against Longo in his personal capacity.
