It was only last week that we got confirmation that The CW’s “The Flash” and CBS’ “Supergirl” would be crossing over, and now it’s finally happening. Grant Gustin, who plays The Flash, has posted a photo of himself today alongside current Supergirl Melissa Benoist on the set of the latter’s show.
Gustin will appear on the “Supergirl” episode which is set to air on Monday, March 28th. At present he’s the only confirmed member of “The Flash” cast set to appear in the episode. Benoist’s Supergirl along with a first look as Jonathan Schaech as Jonah Hex in “DC’s Legends of Tomorrow” appeared briefly in a montage of images seen inside a transdimensional wormhole in this week’s episode of “The Flash”.
