What would the world be like if Reed and his team succeed in erasing their past "mistakes"? We already caught a glimpse of what the UU looks like had Doomsday, Ragnarok or Reed's invasion of Europe not happened (assuming I'm correct about what was shown in the preview for next weeks issue). But lets expand on that; We know Pietro and Banner have a bit to atone for so they, too, will probably try to erase part of their past using the infinity gems. How will that reshape the UU? What series of events would change and how would they now have played out?
Keep in mind I think Fialkov isn't allowed to touch Ulrimatum or Death of Spider-Man.
