In this episode:
Bishop and his sister Shard travel back in time in order to stop an alternate and unacceptable future --- a future without Professor Xavier, and where humans battle violently against 'The Leader' Magneto, and his followers who include husband and wife Wolverine and Storm. Can Bishop and Shard convince Wolverine and Storm that someone whom they have never met, Charles Xavier, holds the fate of mutant-human relations in his hands? Can Bishop and Shard convince them to choose to create a future which holds the promise of Xavier and the X-Men but which denies them the love they have found in this life?

X-TRA NOTE:
It was because of the idea of what could have happened if Xavier didn't exist, that X-Men comic book writers decided to later create "The Age of Apocalypse" storyline.

X-TRIVIA QUESTION:
NOTE: You'll need to be very observative when watching this episode.
One of the characters in the alternate present (see short cameos) has only one arm (probably lost during the war), who is that character?
