The Flash will be appearing in Supergirl on March 28th. Should be interesting...

And Supergirl was glimpsed in this week's Flash during an interdimensional journey. There's some speculation that Flash will end up jumping to her universe in March, rather than them being in the same universe.

This looks promising

Who's the guy in the middle? And more important, why do I find him more interesting than the two in tights? :P


(Additional fundamental questions: is that in the background Lois' home? Are we alone in the universe? Do gravitational waves exist? Wait, that has been answered...)

Greg Berlanti, one of the writers/producers of Flash, Arrow and Legends of Tomorrow, executive producer of Supergirl.
