I was a skeptic when the Beast brought them to the present, kinda drifted in and out of the X-titles. I loved the Battle of the Atom's crazy confusion and just hopped in there...but always had it in the back of my mind that even if the O5 do go back to the exact moment they were extracted from time and try to live out their lives as predetermined by their future (our present) selves ....even unintentional glitches could dramatically alter the course of history. Like so many books and movies...I just don't think they have a clear vision of how to end any of this poetically. Maybe I have unrealistic expectations. The O5 are out in space encountering all manner of fantastic and inexplicable technology and interstellar life forms and they're supposed to reassimilate into 60s society without making a ripple. Maybe that in itself is the story they should tell post GotG. Or maybe they could somehow be merged with their present selves. In the MU, merging doesn't sound terribly far fetched. Would the fused consciousness of past and present Cyclops turn himself in for his Phoenix-induced murder of Professor X? Would Iceman be more or less likely to become one of the most powerful mutants on the planet? Would Archangel salvage at least a portion of the man he once was? Would Beast still be incredibly charming and brainy? (the answer to that one is yes.) Would there at least be some semblance of a 616 Jean Grey alive and powerful and an integral catalyst for the Jean Grey school's success? And Wolverine and Jean finally get together ...I'm conceding on this one. Hate the idea, but after all the friggin' googly eyes...might as well just go there for Odin's sake. Not an alternate universe Jean or an illusion or a shapeshifter. Jean and Logan together...with a defeated Cyclops. You know you wanna see it.
Or....y'know, something like that.
