Re: So what will be this Preventable Event?
If the past of DOFP Is still In 1960's Cyclops,Jean,and Storm will not Be In that part of film.
Storm may be In future scenes.
As I keep saying you can't have Cyclops,Jean,and Storm In 1960's.
Wolverine won't be joining the team.Wolverine from post X-Men trilogy may travel back
or exchange minds with younger self.
