History Heartwarming / XMenDaysOfFuturePast

* Charles [[spoiler: convincing Raven not to shoot Trask by appealing to her better nature and then letting her make her own choices. And it works.]]

* 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.''

* 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. Now the roles have reversed, and Logan is guiding the bitter Xavier into becoming a better man.

** Watch Erik carefully in the scene where Peter is rescuing him. You can see that the man really wants to be annoyed with the younger boy because of his attitude, but is restraining himself because A) Said boy is rescuing him, and B) Said boy is also a mutant, therefore a brother in arms.
*** And C) depending on how you interperet Peter's MythologyGag, he may or may not be his son.
* The ending, where Wolverine wakes up [[spoiler: in the changed future. Especially when he realizes that Scott and Jean are alive again.]]
** Particularly Wolverine's heartfelt, [[spoiler: "It's good to see you, Scott," considering their adversity in the first two films.]]

* Magneto goes [[spoiler:to retrieve his helmet]] before he even knows that [[spoiler:Charles has regained his powers]]. Just goes to show how much faith he has that [[spoiler:Charles will recover from his psychological wounds]] and attempt to stop Magneto.

* 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.

* Magneto goes [[spoiler:to retrieve his helmet]] before he even knows that [[spoiler:Charles has regained his powers]]. Just goes to show how much faith he has that [[spoiler:Charles will recover from his psychological wounds]] and attempt to stop Magneto.

* A slightly meta example, but hearing John Ottman's X-Men theme for the first time in ten years brought a smile to the faces of several fans.

* 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 adopted 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.

** 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 Good!Future we see that same little boy walk past his door in the Xavier school, healthy, seemingly happy, and alive.

* With the film's explanation that the blue furry form for Beast is him hulking out when he loses control of himself, him being that way all the time in the future could be interpreted as Beast no longer feeling like he needs to hide that he is a mutant.
* Mystique saving [[spoiler: four mutants, including Havok and Toad from the horrible fate of being lab rats]] shows she's the only one fighting for Mutant rights.

* Magneto goes [[spoiler:to get his helmet]] before he even knows that [[spoiler:Charles has regained his powers]]. Just goes to show how much he believes [[spoiler:in Charles finding his way,regaining his powers ]]coming after Magneto again.

* 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.

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 if 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.

* Mystique saving [[spoiler: four mutants, including Havok and Toad from the horrible fate of being lab rats]] shows she's the only one fighting for Mutant rights.

* For certain shippers, seeing Bobby and Rogue together again at the end.

** 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 leaves,]] you can tell that Havok misses his old friend.

*** Also the fact that Wolverine is subtly admitting that his time with the X-Men has been the best times of his life

* [[spoiler: Future!Professor X holding 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.]]
