Jay as Zoom.....perhaps being possessed by Zoom....hmmm.
I never said I wanted Flash/arrow to crossover to Gotham but that doesn't mean Hamil couldn't appear on Gotham.
Have Jay and Zoom ever been shown together? Meh, that wouldn't matter; if Reverse Flash was fast enough to show both him and Wells in the same room, Zoom could definitely do the same trick.
I was hoping that Wally would be a ginger too. Either they would hire a person of color with natural red hair; or the actor would have dyed his hair red.
