Tomorrow's Legends

This week, we join the Legends in 1942, the year in which they were doomed to die as they team-up with the Justice Society of America. But before they join forces, the JSA captures the Legends in a battle where they show off their coordination and super powers. Our "team" just cannot keep up! The JSA deliberate how to best deal with the Legends, who at best belong in a mental institution according to their assessment, and refuse to believe their time travel story. Dr. Heywood reveals intimate details about Commander Steel, details only a very close family member would know, and we learn Dr. Heywood has met his own grandfather who died before he was born. The JSA release the Legends from their prison and they explain how and when they have met Rex Tyler. In flashback, Rex Tyler informs the team they will all die in 1942 and proceeds to vanish right before their eyes. Tyler has no recollection of this encounter because for him, in 1942, it hasn't happened yet.  We cut to Paris 1942 and see Eobard Thawne meeting
