Due to changes to his personal timeline, Martin Stein and his wife had a daughter, Lily (Christina Brucato), who apparently lives in Central City and loves her parents very much. Oops?
Legends of Tomorrow fans have been watching Martin Stein struggling with the fact that he seems to be gaining new memories from a timeline that he and the Legends inadvertently changed.
He has been seeing images and feeling love for a girl he had no knowledge of, and the big question has been of her identity.
