Re: Who is the "key historical figure"?
I change my mind.
If Sentinel program is released and Sentinels destroys everything in future, does that mean Mystique killed someone in 1973?
Or someone stopped her? Maybe it's not Nixon, he didn't die in 1973 in reality.
If someone stopped her in old timeline, now Magneto stops Mystique, does that mean it's just a loop, nothing gonna change in future? I think she killed someone, so it can't be Nixon.
Past has to be changed to create new timeline, if now Mystique is stopped, then in old timeline she killed this mystery character.
