Which alternate reality character stays and/or which sole and only character remembers the events of this yet another time-travel/alternate reality event?
I think it was Frenzy after Age of X, and Bishop and Jean after the last alternate reality story from a couple years ago. Or was that the alternate reality story before last? The one about X-Man? They do this trope so very often that it all blends together. At least this one is doing the mash-the-characters-together thing. That's a fun wrinkle. The event with the Wolverine/Emma Frost mash-up was like 3 years ago so we are very very long overdue to see that kind of thing again.
Oh wait Rasputin VIXXIIIIIX is likely staying because they made the mistake of not having her stay in 616 needlessly after Powers of X.
