* 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]].

* 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.]]

* 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.]]

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.

** 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 [[spoiler: she has every reason to hate Nixon's administration for approving the Sentinel programme]].

* 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.
