Although fans were a little surprised to hear that Tom Cavanagh would be coming back for a second season of The Flash, the announcement was nonetheless welcome! With Harrison Wells dead and Eobard Thwane erased from existence entirely... just who the heck could Cavanagh be playing?
However, show exec Gabrille Stanton has revealed what we can expect from Cavanagh:
Harrison Wells will be back, but he's going to be a very different Harrison Wells than we've seen before, We've got other worlds. We've got other timelines. All I'm going to say is he's from one of those places.
Is anyone else thinking... Earth 2?
