We saw Charles Xavier getting completely annihilated by Jean in the movie "X Men: The Last Stand". But, in the last movie in the series, "X Men: The Days of Future Past", we see Xavier alive. While there's a possible explanation of his existence in the changed parallel reality we see in the last, I cannot understand how he was alive in the first reality. If anyone can shed light on this matter, it'll be greatly appreciated. Thanks. 😊
