Well, his future has already undoubtedly been changed by now. I think it’d be interesting to see him escape back to his future only to find it’s drastically different. He prevented the future that Ahab came back from, where one of the teen O5 died in the present, but now there’s some other threat. Maybe Stryfe? Wouldn’t mind seeing he and Cable mix it up one more time in some epic showdown in the future, then end Stryfe for good. At least the clone of Nathan version. Then have someone else pick up the armor and become a new mysterious threat. Something like that.
