Last night’s episode of Supergirl really didn’t show that much as far as the crossover was concerned and honestly we weren’t expecting much to be shown. It was a solid episode, but we’re ready for some major crossover action.
We have the promo for tonight’s episode of The Flash and we also have a nice little behind the scenes featurette of this major t.v. event.
