In case you're interested,I read a news item on Facebook about a possible crossover of Supergirl and the Flash(airing on the CW network) at the end of March....!
Stay tuned!!!! :)
Black Rose--Yeah, I read about that too. Supergirl did appear (very briefly) in The Flash this past week, so her existence has already been acknowledged. Now if they'd just include a glimpse of the cinematic universe . . .
