OPINION AND ORDER
SHIRA A. SCHEINDLIN, District Judge:1. INTRODUCTION
This is a section 1983 action for five constitutional violations allegedly suffered by Damon Vincent while he was incarcerated Green Haven Correctional Facility (“Green Haven”).1 The first four claims are for retaliation under the First Amendment. The fifth claim is for failure to protect under the Eighth Amendment. On February 11, 2013, Defendants moved for judgment on the pleadings, which the Court denied on September 20, 2013, holding that Vincent’s claims were too fact-bound to be resolved as a matter of law.2 Since then, the record has ripened. Defendants now move for summary judgment on all five claims. For the reasons set *333forth below, defendants’ motion is GRANTED in part and DENIED in part.3
II. BACKGROUND4
Vincent asserts constitutional violations in connection with five incidents, all of which allegedly occurred during the Spring and Summer of 2009. Incidents one, three, four, and five are based on retaliation. Incident two is based on the failure to protect. For clarity’s sake, they will be presented in chronological order.
A. Claim One
Vincent alleges that on March 11, 2009, Corrections Officer (“CO”) Sitnewski sexually assaulted him because of his pending lawsuits. Specifically, Vincent alleges that Sitnewski conducted a pat and frisk search, groping Vincent’s genital area, and remarking: “Isn’t one of your lawsuits about this, can’t nobody see if I fuck you in the ass.”5 On March 16, 2009, Vincent filed an internal complaint outlining this allegation.
B. Claim Two
Vincent alleges that on May 8, 2009, a fight occurred in the prison courtyard, at which time Vincent, a non-participant, was assailed from behind by an unidentified inmate in the prison yard. Vincent alleges that defendants watched the fight proceed for nearly five minutes before intervening, and that in the interim, Vincent suffered severe facial lacerations. Accordingly, Vincent argues that C.O. Kovacs — who was 'stationed in the courtyard observation tower — and C.O. Frederick and C.O. Relf — -who were among the officers called to break up the fight — did not take sufficient steps to protect him from injury, thereby violating his Eighth Amendment rights. On May 20, 2009, Vincent filed an internal grievance outlining this allegation.
Prison records make clear that C.O. Ko-vacs, upon witnessing the fight, called for a response team, and that C.O. Frederick and C.O. Relf (among other officers) responded in a timely manner.6 Vincent offers no evidence to rebut the version of *334events memorialized in the records. Instead, he relies on his own view that the officers did not proceed as quickly as they could have.7
C. Claim Three
Vincent alleges that on May 28, 2009, he was retaliated against for filing grievances in connection with Claims One and Two. Specifically, Vincent alleges that at approximately 2 PM, C.O. Carter, with the cooperation of. C.O. Stetson, handcuffed Vincent to his bedpost, telling him “[t]hat will keep you from complaining,. you will learn asshole.”8
Vincent was allegedly left in this position for almost eighteen hours, unable to move around his cell and deprived of access to the toilet. Vincent further alleges that another officer — whose name he did not know — witnessed him handcuffed to the bed and did nothing. Neither officer on duty in Vincent's housing block the evening and night of May 28 — C.O. La-londe and C.O. Coccitti — testified to seeing him (or any other inmate) handcuffed in the manner described by Vincent.9 ,
D. Claim Four
Vincent alleges that on June 8, 2009, C.O. Depo and Lt. Schmidt intruded on him while showering, and left him in the shower room nude, removing both his clothes and the shower curtain. ,Lt. Schmidt explained that the point was to see what “kind of man” Vincent was “without his pen” — allegedly a reference to Vincent’s complaints in connectiqn with Claims One and Two. Vincent was allegedly left in the shower for approximately an hour, during which time various other officers — including at least one female officer — passed by and ■ viewed his naked body. On June 10, 2009, Vincent filed an internal grievance outlining this allegation.
E. Claim Five
Finally, Vincent alleges that on June 25, 2009, C.O. Relf entered his cell and verbally harassed him. Relf allegedly admonished- Vincent not to file any more grievances, and warned him that if Relf caught Vincent doing “any of that Muslim stuff around here,” he was going to return to Vincent’s cell .and “jump” him.10 On July 1, 2009, Vincent filed an internal grievance outlining this allegation.
F. Defendants’ Response
' Defendants have moved for summary judgment on ■ the grounds that all of Vincent’s allegations either (1) are factually baseless or (2) fail to satisfy the elements of the relevant constitutional claim. Alternatively, defendants argue that they are entitled to qualified immunity in connection with every incident alleged by Vincent.
III. STANDARD OF REVIEW
Summary judgment is appropriate “only where, construing all the evidence in the light most favorable to the non-movant and drawing all reasonable inferences in that party’s favor, there is ‘no genuine issue as to any material fact and .,. the movant is entitled to judgment as a matter of *335law.’”11 “A fact is material if it might affect the outcome of the suit under the governing law, and an issue of fact is genuine if the evidence.is such that a reasonable jury could return a verdict for the nonmoving party.”12
In deciding a motion for summary judgment, “[t]he role of the court is not to resolve disputed issues of fact but to assess whether there are any factual issues to be tried.”13 ‘“Credibility determinations, the weighing of the evidence, and the drawing of legitimate inferences from the facts are jury functions, not those of a judge.’ ”14
IV. APPLICABLE LAW15
A. Retaliation
“ ‘To prevail on a First Amendment retaliation claim brought under 42 U.S.C. § 1983, a prisoner must demonstrate (1) that the speech or conduct at issue was protected, (2) that the defendant took adverse action against the plaintiff, and (3) that there was a causal connection between the protected speech and the ad-verse action.’ ”16 “[Cjourts must approach prisoner claims of retaliation with skepticism and particular care.”,17 “Only retaliatory conduct that would deter a similarly situated individual of ordinary firmness from exercising his or her constitutional rights constitutes an adverse action for a claim of retaliation.”18
’ In other words, the fact that adverse action was taken against an inmate is not enough.’ to sustain a retaliation claim. Rather, the inmate must demonstrate that the adverse action was of a sufficiently serious nature to deter a reasonable inmate from exercising his or her constitutional rights.19 This question, like “the question of causation, [ ] is factual in nature.”20 In determining whether an individual of ordinary firmness would be deterred from exercising his or her constitutional rights, “the court’s inquiry must be ‘tailored to the different circumstances in *336which retaliation claims arise,’ bearing in mind that ‘[prisoners may be required to tolerate more .., than average citizens, before a [retaliatory] action taken against them is considered adverse.’ ”21
Furthermore, the fact that an inmate has filed a lawsuit should not be taken to imply that the retaliatory conduct was not sufficient to deter a person of ordinary firmness from exercising his or her rights. As the Second Circuit has explained, “that a particular plaintiff ... responded to retaliation with greater than ‘ordinary firmness’ does not deprive him of a cause of action.”22 And this is especially so in cases — like this one — where the plaintiff “is no stranger either to the grievance system or to the federal courts.”23
B. Failure to Protect
To establish an Eighth. Amendment violation based on an official’s failure to protect, an inmate must satisfy a two-pronged test. First, an inmate “must show that he is incarcerated under conditions posing a substantial risk of serious harm.”24 Second, an inmate must show that prison officials acted with “deliberate indifference” to the inmate’s “health or safety.”25 A prison official can' only be said to act with deliberate indifference insofar as he or she “has knowledge that an inmate faces a substantial risk of serious harm and he disregards that risk by failing to take reasonable measures to abate the harm.”26 To satisfy this standard in the context of an altercation, an inmate must show that “(1) the officer had a realistic opportunity to intervene and prevent the harm; (2) a reasonable person in the officer’s position would know that the victim’s constitutional rights were being violated; and (3) the officer [did] not take reasonable steps to intervene.”27
C. Qualified Immunity
“The doctrine of qualified immunity protects government officials ‘from civil damages insofar as their conduct does not violate clearly established statutory or constitutional rights of which a reasonable person would have known.’”28 A court must consider “both the clarity of the law establishing the right allegedly violated as well as whether a reasonable person, acting under the circumstances then confronting a defendant, would have understood that his actions were unlawful.”29 Qualified immunity is not properly granted where the facts alleged show that the official’s conduct violated a constitutional right and the right was clearly established.30 “A *337right is clearly established if (1) the law is defined with reasonable clarity, (2) the Supreme Court or the Second Circuit has recognized the right, and (3) ‘a reasonable defendant [would] have understood from the existing law that [his] conduct was unlawful.’ ”31
V. DISCUSSION
A. Failure to Protect
Vincent’s failure to protect claim fails as a matter of law. Beyond mere speculation, Vincent has not offered a single piece of evidence to support his contention that C.O. Kovacs was dilatory in calling a response team to the prison yard. Nor has he offered evidence that C.O. Frederick or C.O. Wolf, once they arrived in the yard, faded to discharge their responsibilities. What is more, Vincent has also failed to show that C.O. Kovacs, C.O. Frederick, or C.O. Wolf had actual or constructive knowledge that Vincent, in particular, faced harm in the prison yard.32 No reasonable finder of fact could hold C.O. Kovacs, C.O. Frederick, or C.O. Wolf liable for failure to protect.
B. Retaliation Claims
Vincent’s retaliation claims are another story. All four claims — Claims One, Three, Four, and Five — raise issues of fact sufficient to render summary judgment inappropriate.33
1. Claim One
Defendants do not deny the core allegation of Vincent’s first claim — that C.O. Sitnewski groped Vincent’s ■ genitals while making a threatening reference to his past complaints. Instead, they focus on the legal sufficiency of Vincent’s retaliation claim. First, defendants argue that genital groping, as described in Vincent’s complaint, is insufficiently serious to “constitute an adverse action” as a matter of law.34 Second, they point to the fact that Vincent’s lawsuits were filed years before the alleged retaliation, and they addressed incidents that happened elsewhere. Accordingly, defendants argue that Vincent has not shown the necessary “indicia of a causal connection” between his protected expression (the filing of lawsuits) and the allegedly retaliatory act.
Both of these arguments fail. With respect to the first, defendants rely heavily on Boddie v. Schnieder;35 a Second Circuit case holding that plaintiffs allegation of being verbally harassed and sexually touched without consent “did not involve a harm of federal constitutional, proportions *338as. defined by the Supreme Court.”-36 Likewise here, argue defendants — because Vincent has failed to allege anything more severe than what occurred in Boddie, there is no “adverse action” to support his retaliation claim..
What the Government fails to mention is that Boddie concerned an Eighth Amendment claim, which — for good reason — carries a more stringent burden than First Amendment retaliation. For an officer to. be liable under the Eighth Amendment, not .only must he have a “culpable” mental state; he must subject an inmate to an “unnecessary and wanton infliction of pain.”37 By holding that verbal harassment and non-consensual'sexual touching did not rise to that level, the Second Circuit had. no occasion to address whether it constituted an “adverse action” for First Amendment purposes.
If anything, the reasoning in Boddie cuts against defendants’ position. In the same breath that it dismissed Boddie’s claim, the Second Circuit also called the alleged groping “despicable,” and took care tó emphasize that even if “the episodes of harassment and touching alleged by Boddie” did 'riot support an Eighth Ariiendment claim, they could nevertheless support other causes of action — including “state tort actions.” 38 Here, the question is whether Vincent’s allegations, which are strikingly similar to the “episodes” in Bod-die, suffice to sustain a retaliation claim. Is sexual groping- by an officer who is simultaneously issuing verbal threats the kind of action that would deter a person of “ordinary firmness” from exercising his or her constitutional rights? This is plainly a question of fact. Defendants can certainly raise their - “person of ordinary firmness” argument at trial — and if the argument succeeds, Vincent’s retaliation claim will fail. But it would be inappropriate for the Court to resolve the issue at this stage.
Defendants’ second argument fares no better. “Even assuming arguendo that the alleged groping constitutes an adverse action,” defendants argue that Vincent has failed to “proffer any facts to support the requisite causal connection between the alleged groping and a previously filed lawsuit.” For support, defendants point to the fact that Vincent’s previous lawsuits— the lawsuits for which C.O; Sitnewski was supposedly retaliating — concerned incidents that occurred'at different correctional facilities, and that C.O. Sitnewski was not a named defendant in any of them.
This argument is' puzzling. Although defendants are certainly correct that. “[a]s a general matter, it is difficult to establish - ... retaliation [by one officer] for complaints against another [officer],”39 generalities do not resolve particular cases. According to Vincent, C.O. Sitnewski, in the midst of-groping his genitals, said, “Isn’t one of your lawsuits about this, can’t nobody see if I fuck you in the ass.” This might not be-true, of course.. But if it is true, a trier of fact could certainly infer *339that C.O. Sitnewski was motivated by a retaliatory purpose — i.e., that the groping was meant to penalize Vincent for bringing past grievances, and to dissuade future grievances. The claim cannot be dismissed as a matter of law.
2. Claim Four
Claim Four is amenable to essentially the same analysis as Claim One. Vincent alleges that C.O. Depo and Lt. Schmidt intruded on his shower, removing the shower curtain and his clothes, leaving Vincent naked in the shower room for approximately an hour. Furthermore, Lt. Schmidt allegedly told Vincent that he wanted to see “what kind of man” Vincent was “without his pen” — a thinly-veiled reference, Vincent argues, to his previous complaints.
As with Claim One, defendants’ strategy here is to argue that Vincent’s allegations, even if true, fail to satisfy the elements of retaliation. First, the Government argues that whatever psychological harm Vincent suffered as a result of the shower incident, it was only de minimus — and therefore insufficient to ground a First Amendment claim.40 Once again, however, defendants have confused the injury required in the retaliation context — adverse action — with the more exacting standard of harm required under the Eighth Amendment.41 Vincent’s allegations do not rise to the level of the latter. But do they describe action that would make a person of “ordinary firmness” disinclined to exercise his rights? Defendants find this proposition “[im]plausibl[e].”42 Vincent clearly thinks otherwise. Which side is right is a question of fact.
Second, defendants dispute Vincent’s theory of causation. Citing to the same case law invoked as to Claim One,43 defendants argue that “[tjhere is nothing in the record to indicate which .grievance or grievances” Lt. Schmidt was referring to when he made reference to Vincent’s “pen,” or whether he was “talking about [Vincent’s] grievances at all, if in fact [Lt, Schmidt] said what he is alleged to have said.”44 But both questions — whether Lt. Schmidt made the remark about the pen, and, assuming he did, what the remark meant — are issues of fact.' Defendants are correct that “nothing in the record” supports Vincent’s allegation. But given the nature of that allegation, what evidence (apart from Vincent’s own testimony) plausibly could support it? Greenhaven likely does not keep records about the humiliation tactics employed by officers against inmates, and Vincent had no opportunity to perform an investigation to secure physical evidence. Ultimately, the viability of Vincent’s claim comes down to the credibility of his account. That is for the jury to decide.
3. Claim Five
The same basic analysis applies to Claim Five. Vincent alleges that C.O. Relf entered his cell and warned Vincent that if he filed any more grievances, or if Relf caught him doing “any of that Muslim stuff around here,” Relf was' going to “jump" him. Defendants do,not argue— nor could they argue — that Relfs threat was not causally connected to Vincent’s past. grievances.' Relf drew the connection explicitly.. Instead, defendants focus on the severity of the retaliatory conduct. According to defendants, Vincent’s “alle*340gation that C.O. Relf threatened to jump him, without anything more, does not constitute [] an adverse action,” because under Second Circuit law, “[i]t is well-established that insulting or disrespectful comments directed at an inmate generally do not rise to the level of conduct that would deter [the exercise of] constitutional rights.”45
Defendants are right on the law, but they misrepresent the facts of this case. The Second Circuit has explained that “insulting or disrespectful comments directed at an inmate,”46 as well as “verbal responses of resentment or even ridicule [in response to inmate complaints],”47 do not give rise to retaliation claims. Here, however, Vincent does not allege that C.O. Relf insulted or ridiculed him—he alleges that Relf threatened him with physical harm. As to that kind of comment, the Second Circuit has not definitively spoken, and courts in this District are split.48 In the absence of further guidance, I decline to grant summary judgment on Claim Five. A reasonable juror could find that the prospect of being “jumped” by an officer, even if no physical altercation actually occurred,49 would deter an inmate of “ordinary firmness” from asserting his or her constitutional rights.
4. Claim Three
Finally, Vincent alleges that C.O. Stetson and C.O. Carter handcuffed him to a bedpost for eighteen hours, as payback, they explained, for his grievances. Here, defendants change their tack. Although they make a faint-hearted attempt to suggest that being handcuffed to a bedpost does not qualify as an adverse action,50 and to dispute Vincent’s theory of causation,51 *341these arguments are only briefly presented. Instead, defendants spend considerable time and energy arguing that Vincent’s allegation “strains credulity,”52 and should be dismissed as ‘“wholly incredible.’”53 For support, defendants point to the fact that other officers — such as C.O. Coccitti, who was assigned to patrol Vincent’s cell block the night of the alleged incident — did not “not[e]” any “unusual activity” during their rounds.54
That no officer has come forward to inculpate C.O. Stetson and C.O. Carter is hardly a surprise. Even if other Greenha,-ven officers had witnessed something out of the ordinary, the likelihood of their, saying so is slight — “[t]he notion of a corrections officer trying to protect [his or her] own is hardly fantastical.”55 Furthermore, the cases cited by defendants deal with contradictory allegations, not allegations that seem unlikely as a matter of fact. For example, in Jeffreys v. Rossi56— a case presided over by this Court, and ultimately affirmed by the Second Circuit57 — plaintiffs theory of the case required him to deviate from, and at times blatantly contradict, the story that he originally relayed to law enforcement. After admitting numerous times (to multiple officials) that he had jumped out of a third-story window, and that his injuries stemmed from the resulting fall, plaintiff changed his version of events nine months later, weaving an intricate tale of excessive force, which included, inter alia, forcible defenestration by the police.58 This revisionist account of events was “so replete with inconsistencies,” and so plainly grated against the rest of the record, that “[no] reasonable jury could [have found] that excessive force was used against [plaintiff].” 59
Here, by contrast, Vincent has not contradicted himself, or otherwise given the Court reason to doubt the coherence of his allegations. Defendants have made clear that they find those allegations improbable. But improbability is not the same as inconsistency. Where the latter concerns the relationship between allegations (or different versions of the’ same allegation), the former ultimately requires a detérmination of credibility — and “it is axiomatic,” of course, “that courts should not assess credibility on summary judgment.” 60 As the' Supreme Court has ex*342plained, :claims should only be dismissed as “factually frivolous” at- the summary judgment stage if they are “fanciful,” “fantastic,” .or “delusional,” not because “the court finds [a] plaintiffs allegations unlikely.”61
The allegations here are quite serious. If Vincent’s version of events is true, two officers used their position of power to threaten and dehumanize an inmate they were supposed to protect. According to defendants, Vincent’s story is “incredible, if not absurd.”62 But that is not a judgment I can make—particularly given the state of correctional facilities right here in New York. Just this' month, the City agreed to a far-reaching settlement with inmates from Rikers Island, after the U.S. Attorney’s Office of Manhattan “issued a blistering report that found rampant use of unnecessary and excessive force by correction officers against adolescent inmates and the widespread violation of their civil rights.”63 What if one these inmates had filed a 1983 claim and—as here—offered no evidence beyond his own version of events? Presumably—as here—defendants would have waved off the allegation as “frivolous.” But that just underscores why credibility determinations are best left to finders of fact. What seems “fanciful” or “delusional” to one person may seem perfectly reasonable to another. Vincent should have an opportunity to relay his story to a jury.
C. Qualified Immunity
Finally, the officers aré not entitled to qualified immunity on any of the three surviving claims. Defendants argue that their conduct, regardless of its constitutionality, “[did] not violate [a] clearly established ... right[ ].”64 But if Vincent succeeds in demonstrating that retaliation occurred, the right imperiled by officers at Greenhaven—the right to speak out without fear of reprimand—was well-ingrained at the time of the disputed 'conduct. Retaliation claims have long been a fixture of First Amendment law. Only a “plainly incompetent” officer—or one who was intentionally violating the Constitution— would think it permissible to single out an inmate for adverse action because he spoke out against something that happened (to him or someone else) in the prison.65
Defendants’ secondary argument also fails. Even. assuming that the law grounding Vincent’s claims “could be deemed to have been clearly established,” defendants nevertheless contend that “it was reasonable for an official in [their] position to have believed that no such law existed.”66 Whether or not that is true, it is irrelevant. Qualified immunity does not permit an “ignorance of the law” defense. For good reason—allowing officials to escape liability because they do not know what the law requires of them would set exactly the wrong' incentives. And it *343would undermine the key virtue of qualified immunity doctrine — that if nothing else, the “clearly established” test is objective. The defendants in this case either violated Vincent’s well-established rights, or they did not. Either way, qualified immunity affords them no shield.
VI. CONCLUSION
For. the foregoing reasons, the Government’s motion for summary judgment is GRANTED in part and DENIED in part. The Clerk of the Court is directed to close this motion (Dkt. No. 78). Furthermore, because this case is proceeding to trial, and because Vincent’s claims satisfy the standard set forth in Hodge v. Police Officers,67 the Clerk of the Court is also directed to find pro bono counsel to represent Vincent. A status conference is set for July 21, 2015 at 4:30 PM.
SO ORDERED.
. Vincent also raised a sixth claim — under state law — which was dismissed on September 20, 2011. See Vincent v. Sitnewski, No. 10 Civ. 3340, 2011 WL 4552386 (S.D.N.Y. Sept. 10, 2011).

. This case was originally assigned to another judge of this District, who — in an abundance of caution — appears to have construed Vincent’s allegations of retaliatory conduct as giving rise both to traditional First Amendment claims and to freestanding Eighth Amendment claims. See id. at *1 ("[Vincent’s] complaint alleges that defendants took adverse action against Sitnewski in retaliation for certain grievances and lawsuits which Vincent filed, and- also alleges violations of Eighth Amendment rights.’’). Read holistically, however, the claims arising from the adverse actions that Greenhaven officers allegedly took against Vincent are uniformly retaliation claims. Cf. Johnson v. City of Shelby, — U.S. -, 135 S.Ct. 346, 190 L.Ed.2d 309 (2014) (per curiam) (explaining that allegations should be construed for substance, not form). This is how defendants, in their papers, have parsed Vincent’s claims. And it is even how Vincent himself describes those claims, in the preliminary statement of his opposition papers. After tallying a list of ostensibly independent constitutional causes of action, Vincent explains that “all [of the foregoing]” was "in retaliation for [my] filing of lawsuits and grievances.” Memorandum of Law in Opposition to Defendants’ Motion for Summary Judgment (“Opp. Mem.”), at 1 (emphasis added). See also id. (describing the same incidents as "the unlawful acts against [me] of retaliation”). I hold, therefore, that Vincent brings only retaliation claims, not freestanding claims under constitutional provisions other than the First Amendment. The analysis proceeds accordingly.

. Compare Hofelich v. Ercole, No. 06 Civ. 1369, 2010 WL 1459740, at *2 (S.D.N.Y. Apr. 10, 2010) (holding that “verbal threats,” if they are "specific[],” can "constitute adverse action” for retaliation purposes), with Rembert v. Cheverko, No. 12 Civ. 9196, 2014 WL 3384629, at *9 (S.D.N.Y. July 10, 2014) (allegation that officers “intimidated [plaintiff]” after he filed a grievance was "insufficient to allege adverse action”). See also Mateo v. Fischer, 682 F.Supp.2d 423, 434 (S.D.N.Y.2010) (collecting cases in both directions).
. Defendants emphasize that "[Relfs] threats never amounted to anything” to bolster the view that those threats did not rise to the level of adverse action. Def. Mem. at 20. Some judges in this District have agreed with this reasoning. See, e.g., Fischer, 682 F.Supp.2d at 434 (citing the fact that defendant "never followed through on [his] threats” as support for dismissal). But it is difficult to see why the materialization of a threat (or not) bears on its chilling effect. The latter turns on whether a threat is perceived as serious, not on whether it actually turns out to be serious.
. The main support for this argument— which the Government wisely does not press—comes from cases about tightly-applied handcuffs. See Def. Mem. at 16 (collecting cases). Putting aside that these cases uniformly involve Eighth Amendment challenges, not retaliation claims, the bigger problem is that apart from involving handcuffs, they have nothing to do with Vincent's allegations. Even "extremely tight” handcuffing is not the same as—is not even in the same vicinity as—the serious liberty deprivation alleged here. See Bender v. City of New York, No. 09 Civ. 3286, 2011 WL 4344203 (S.D.N.Y. Sept. 14, 2011). In Vincent’s words, "[t]his is not a case of excessively tight handcuffs.... [It] is a case of [an inmate] being handcuffed for seventeen hours to his bed.” Opp. Mem. at 22.
. See Def. Mem. at 15 (describing Vincent's view of causation as mere "guess work”). As with Claims One and Four, however, the trouble with the Government’s position is that Vincent has clearly alleged that C.O. Stetson and C.O. Carter made verbal reference to his *341grievances. To deem this allegation "guess work” — and grant summary judgment on that basis — would, in practice, be nothing more than a determination of Vincent’s credibility. At this stage, that is precisely what this Court is supposed to avoid. See Jeffreys v. Rossi, 275 F.Supp.2d 463, 475 (S.D.N.Y.2003) ("It is axiomatic that courts should not assess credibility on summary judgment.”).
