Re: 3 Reasons "Days Of Future Past" Is Actually X4
Imagine if they follow the last animated series/the comic and use Xavier instead of Kitty? Have him "send his mind" back to his 70's self. That could also give Charles and Erik in the past a reason to rebuild cerebro. Charles keeps getting flashes of things (from the future) and needs cerebro to amplify it.
But anyway, after everything gets resolved, present Xavier's mind returns to his future self, and when he wakes up Scott, Jean and Storm can be by his bedside. Roll credits.
