Grant Gustin instagram page is flowing with set photos from The Flash, Supergirl episode, “Worlds Finest” airing on March 28.
Given that Supergirl airs on CBS and The Flash airing on The CW it will be interesting to see how this episode takes whole. The last episode of The Flash showed Cisco, Barry and Dr. Wells entering Earth 2 and their were quick clips of different DC Universes (You can watch the clip below). It’s safe to assume that Barry some way, somehow enters her universe.
