History Heartwarming / XMenDaysOfFuturePast

* After Future!Erik[[spoiler: is hit by shrapnel and is dying]], he does not fight the Sentinels but rather strengthens the Barricade.[[spoiler: He uses the last of his strength not to fight his enemy like he's been doing his whole life, but to protect his friend.]]

--> '''Logan:''' I don't know how long I've got here, but I do know that a long time, actually, a long time from now, ''I'' was your most helpless student, and ''you'' unlocked my mind. ''You'' showed me what I was, you showed me what I can be.

[[caption-width-right:350:''"All those years wasted fighting each other, Charles. To have back but a precious few..."'']]

* And beforehand, somehow even Cerebro's standard greeting is heartwarming: "Welcome Professor. . ."

** Before that, Mystique [[spoiler: disguised as President Nixon offering herself to be killed by Magneto, in place of Nixon and his entire Cabinet. Then saving them all]]. Even though she has every reason to hate Nixon's administration for [[spoiler: approving the Sentinel programme]].

** [[spoiler: Nixon cancelling the Sentinel program, and potentially pardoning Mystique]].

* When Logan talks to Past!Magneto on the plane and the latter tauntingly asks him how being his enemy worked out for him, Logan simply replies "You're like me. You're a survivor." The fact that, out of all the other things Logan could have called him (murderer, terrorist etc.), he actually chooses to [[WorthyOpponent identify with his old enemy is rather touching]]. It also suggests that Future!Magneto may have further redeemed himself in Logan's eyes by genuinely fighting only for the survival of himself and his people, since in previous films Logan has always been quick to call Magneto out on any hypocrisy ([[Film/XMen like sacrificing Rogue rather than himself]]). Finally, it shows what a good influence the X-Men have been on him over the years; it's hard to imagine a younger Wolverine choosing to stand down from that sort of provocation instead of rising to it.

* The younger Charles' paternal side (which he has suppressed for a decade) surfaces for a moment when he tells Peter to "take it slow." Quicksilver's grin expresses more than simple amusement at the little joke; he comes from a fatherless household, and he generally disregards any form of authority, but you can sense in that moment that the teen thinks Xavier is a pretty cool guy.

* One example that is mixed with {{Tearjerker}} is the part of the narration that explained the fact that when the Sentinels started their genocide of mutants, many humans stood up for mutantkind. While it did not change the outcome, when it came down to the wire, a chunk of humanity tried to do the right thing and did not simply abandon the mutants to their fate. ''Charles was right all along.''

** [[spoiler: One major thing that sticks out in their conversation is that future!Charles ''still'' hasn't given up on humanity. This is a man who has seen the near complete genocide of his species, the deaths of countless numbers of his friends and students, all at the hands of homo sapiens. And he still has faith.

* For certain shippers, seeing [[spoiler:Bobby and Rogue together again at the end]].

* [[spoiler:Future!Professor X briefly shaking Future!Magneto's hand while the latter is dying. Plus Erik lamenting that they spent so many years fighting each other when they should have been working together.]]

* It's established that Quicksilver hates being still, because of his accelerated sense of time. Despite this, he sits down to hold his little sister and watch TV with her.

* The ending, where Wolverine wakes up [[spoiler: in the changed future.]]
** [[spoiler: He's walking around like he can't believe he's in such a cheerful and familiar place. Think about it; he spent decades in the Bad Future and now he's back in the closest thing he has to home.]]
** [[spoiler: He's overjoyed to see Jean alive again and even Scott too. "It's good to see you, Scott," is heartfelt considering their adversity in the first two films.]]
** [[spoiler: Just seeing the school bright and whole and full of children again.]]
--->'''[[spoiler:Jean]]''': Logan, is everything alright?\\
'''Logan''': ...yeah. Yeah, I think it is.
** Early in the film Wolverine tells Beast "You don't know this, but you and I are gonna be really good friends." [[spoiler: Even in the changed future this is completely true.]]
** Logan in the righted timeline is a faculty member at the Xavier school; the history instructor. He truly found a place to belong.
** Wolverine [[spoiler:returning from the past to the peaceful, happier timeline of the present and greeting the Professor after seeing Scott and Jean. The way the Professor's face lights up when he realizes that this is the Logan that helped him in the past without any recollection of the last fifty years is full of relief and comfort for both Logan and the audience and a confirmation that Logan's hard work to fix things in the past paid off]].
* A slightly meta example, but hearing John Ottman's X-Men theme for the first time in 11 years brought a smile to the faces of several fans.
* [[spoiler: Future!Professor X briefly shaking Future!Magneto's hand while the latter is dying. Plus Erik lamenting that they spent so many years fighting each other when they should have been working together.]]
** [[spoiler: This simple gesture, while brief due to the Sentinels about to barge in, shows that whatever difference these two had, they were still friends. And now they have finally buried the hatchet after all these long years. It's sad too, because they know there's nothing else for them since they'll both die soon, but at least they have finally made peace.]]
-->'''Magneto''': All those years we wasted fighting each other, Charles. To have a precious few of them back...

* Meta example: both Patrick Stewart and Ian [=McKellen=] were surprised when Bryan Singer approached them directly about the movie (during a theater production of Waiting For Godot that the two were appearing in) as they thought the roles of Xavier and Magneto had been passed to James [=McAvoy=] and Michael Fassbender, and that they themselves would never play the roles again. According to [=McKellen=] himself, when he and Stewart learned otherwise, they were delighted and signed on right away, eager to play the parts again and to work with the younger cast.
* Charles [[spoiler: convincing Raven not to shoot Trask by appealing to her better nature. Despite that he could telepathically force her not to do it, Charles lets her make her own choices, stating that he has faith in her. And it works.]]
** Before that, Mystique [[spoiler: disguised as President Nixon offering herself to be killed by Magneto, in place of Nixon and his entire Cabinet. Then saving them all]]. Even though she has every reason to hate Nixon's administration for [[spoiler: approving the Sentinel programme]].
** [[spoiler: Before she leaves, Raven looks at Charles and Hank and smiles warmly.]]
** [[spoiler: Nixon cancelling the Sentinel program, and potentially pardoning Mystique]].

* Past!Erik asking Charles for a game of chess after they've had a huge argument, and Charles eventually agreeing. Plus, the way they [[spoiler: almost casually say goodbye to each other when Charles lets Erik go after he's tried to ''kill the president'']], starting their strange FriendlyEnemy relationship they'll have most of their lives.

* Although the younger Charles hasn't seen Mystique in 11 years by the time he finds her at the Paris hotel, his first instinct after she is stunned by a Taser is to try to comfort her by caressing her hair and shoulder while telling her that he will keep her safe along with other soothing words. He also stands in between the barrel and his foster sister after [[spoiler:Magneto points a gun in her direction, and Erik later has to use his power to change the bullet's trajectory so that it won't hit Charles in the head]]. Despite their estrangement, Xavier is willing to die for Raven to save her life.
** And to add to this, Mystique seems genuinely happy to see Charles again when they first meet up.
** Later, when Mystique is getting her leg bandaged, the nurse wonders if the mutant girl from the TV footage has a family. Mystique (in disguise) wistfully replies "Yes. She does."
* In a bizarre way, Beast beating the heck out of Magneto and doing his best to drown him [[spoiler: for trying to kill Raven. Hank still cares deeply about her.]]
* Havok attempting to talk down [[spoiler:Mystique from killing Stryker. She may have abandoned the X-Men, but you can tell he's glad to see her and doesn't want her to pull the trigger.]]
** Not to mention that when leaving, he pauses [[spoiler:and asks, with a small amount of audible sadness, if she is going to leave with them. When she declines and goes to continue her plans,]] you can tell that Havok misses his old friend.
* Towards the climatic battle in the past towards the end of the movie, Hank asks Logan whether or not he makes it in the future. Logan truthfully replies that he doesn't to which Hank gives him a startled look, but Logan then kindly reassures him "But we have a chance to change that." It really encompasses the theme of hope in the movie.
** In the very beginning of the film before the title credits, we see a young mutant boy with a streak of white in his hair scavenging among the ruins of the decaying city shortly before a Sentinel catches up. It's a blink-and-you'll miss it sort of moment, but after Logan wakes up in the [[spoiler:Good!Future, we see that same little boy walk past his door in the Xavier school, healthy, seemingly happy, and alive]].
* For certain shippers, seeing Bobby and Rogue together again at the end.

* Mystique saving [[spoiler:four mutants, including Havok and Toad from the horrible fate of being used as lab rats]] shows she's the only one fighting for Mutant rights.
* A human Senator pointing out to Trask that if mutants exist, then they are living among humans peacefully. This guy in the 1970's is more tolerant than most of the humans we meet in the 21st century.
* Logan telling Xavier "I was your most helpless student once." It reminds us that in the first movie, when Logan was bitter and alone, Xavier was the one who guided him into both being a better person, and having a sense of purpose and belonging. Now the roles have reversed, and Logan is guiding the bitter Xavier into becoming a better man.

* When Mystique asks Beast, "So you've been living here [Xavier's mansion] all these years?", his response is a matter-of-factly "Someone has to take care of Charles." He says it without any resentment (it's not easy looking after someone with mental illness) or resignation (so he doesn't feel trapped by his caretaker role). For Hank, there is no question about what he values more: living his own life, or ensuring that his severely depressed, alcoholic, drug-addled friend doesn't end up killing himself (accidentally or otherwise). Being in a codependent relationship certainly isn't a good thing, but [=McCoy=]'s love and devotion is nevertheless very touching.

Despite their estrangement, Xavier is willing to die for Raven to save her life.

* Right before they part ways at the end of the film, Magneto [[spoiler: leaves his helmet behind on the ground. Yes, Mystique may have pulled it off his head in an earlier scene, but Erik looked right at the helmet -- which was directly next to his feet at the time -- and continued on without it.]] Considering Erik's obsessive need of it in most other parts of the series, this speaks volumes about his trust for Charles, even if he only left it behind out of self-preservation.
** On that note, Future!Erik doesn't wear it, either.
