those rumors a few days ago which i'm still abit if not very skeptical about said [BLACKOUT]jean would appear in this film[/BLACKOUT], if thats true they would be introducing her very early
I don't see them bringing in a teenage Jean shortly after the events in DoFP. Singer has already said those characters didn't fit in FC timeline wise, and they don't fit in the 70's either. If Apocalypse wakes up in the past in the new timeline, I think it would take a few years before he recruited all his Horsemen. I also don't think they will have one movie covering all that. I think I'd be an Apocalypse origins movie. If it takes place in the 70s, they could have Xavier, Beast, Gambit, Mystique, Magneto, and possibly Wolverine. I think they'd jump the timeline to the 80's however.
