In the first clip, The Flash realizes he's on the wrong Earth when Supergirl doesn't recognize him or his other name-drops: Zoom, Green Arrow, Black Canary, and The Atom. In the follow clip, Barry explains to James and Winn how the multiverse works and gets his new friends ice cream to prove how fast he is. The third clip has Cat Grant trying to come up with a name for the new superhero that has arrived to National City. Lastly, Siobhan Smythe proposes a villainous team-up with Livewire.
