Soo... the main, future Wolverine (that we've been seeing in the films) has his consciousness transported to the body of a Wolverine in the nice new timeline at the end, right? He wakes up and he's all like 'WTF. Why is everyone alive?'
Does this mean that there was a Wolverine in this nice new timeline who lived years up to that point, only to get his mind effectively erased and replaced with the mind of the old timeline wolverine who we spent the film with? I mean, they're both Wolverine but one was used to that nice new life at the school while the other was from the war torn future who suddenly wakes up in the body and has no idea what's going on...
Also, how does Professor X even know about the new timeline?
