Re: Smallville Season 11, it"s happening...
Both are retainer by Ted Kord as was mentioned in the episode. Also Bryan Q has stated/implied that the Legion stuff will be touching on Geoff Johns/Greg Ruka/James Robinson's "New Krypton" storyline and of course the July solicits teased the return of Doomsday whom I assume has since resumed his path of destruction some point in the future.
Also we don't know if this factors into the Crisis or not. Since the Legion is involved now, no doubt there will be timey wimey things going on and Brainy will no doubt mention the Crisis
Perhaps this is a Crisis of sorts for the Legion?
LONG LIVE THE LEGION!
