Wait, so the Old5 remember everything from their past selves and every drama that befell mutantkind isn't instantly erased?
Confusing spoiler.
What happened to Rachel?
This issue looks like very eventful and lots of action that could have gone for a few more issues.
I'm just glad that the O5 are finally gone, it should have happened years ago but at least is over and now we can move on.
I do wonder what was the point of giving the current/real 05 the memories of the ones that went back in time. Will any of that actually matter to any of them?
It should. What's matter is that it's there and we can bash writers for not using.
Bobby has memories of a happy relationship where he wouldn't have to pretend to be someone else. Beast got some cool knowledge, kissed his teen crush and also a cute ninja girl. Warren banged a Wolverine, because that's all he had for development. Scott learned that he can have friends outside of the X-Men and had more time than he could ever wish for with his dad. Jean got a new understanding of her powers and has now canon relationships outside of Scott. It's actually reasonable.
After Heroes Reborn, Iron Man came back with some kind of nonsense wonky explanation that the new Tony was a combination of the old Tony who died and teen Tony. It made no sense and was never brought up again except for a gag two years ago. Even though it was a mess of a way to fix things, they got away with it because teen Tony didn't do anything of note, and was immediately cancelled for being unpopular.
The O5, who held titles for five years and 100 issues, got teen Tony'd.
