4. Reconciliation?

Wasted Years

The younger versions of Professor X and Magneto will obviously need to spend some time forgiving each other for past mistakes, but it appears as if their older selves may finally reconcile based on this scene. Bearing in mind just what great friends they were in X-Men: First Class, this could be an extremely emotional moment as the two say goodbye to each other before the Sentinels overpower them (that last bit is purely speculation on our part, but you have to admit that it would be pretty darn cool!). The only still confusing thing about this is that Charles was disintegrated in X-Men: The Last Stand and Magneto was left powerless. Of course, there were hints to the contrary in the final few minutes of that film, but we still need some sort of explanation!
