In the words of Kreisberg, "It’s about to go doppelganger-a-go-go on the show. With time travel last year, we kind of tried to ease everybody into it and we kind of tried to do the same thing here where the first episode was how the two guys look exactly alike and then Jay comes over and we establish the idea of Earth 2." He added they didn’t want to change the feel of the show overall and take over but, that said, the doppelgangers are coming in a big way very soon.
Hello, Harrison Wells
Kreisberg didn't give up too much intel on what we’ll see when we pick up next, but he did say the following: "The next episode opens in a slightly surprising way." As a huge fan of Doctor Who, he cited that show regularly wouldn’t pick up where viewers would expect. "Obviously, this scene will play out," he promised. "I think the beginning of [episode] five is really exciting. You’re going to get a lot of answers to questions you have." As to whether the Wells we saw is a Doppelganger or Eobard Thawne? Keep watching, he advised.
The big Arrow/Flash crossover for this year will start to unfold in the next episodes, but Kreisberg did say "conceptually speaking, one of the ways we thought about these episodes in a macro sense was The Flash episode this year plays more like an episode of Arrow, and the Arrow episode plays more like an episode of Flash." Panabaker added: "It’s exponentially bigger this year too because we factored in all the characters from Legends [of Tomorrow], too.'
Forget Jay Garrick. Caitlin has a much different connection with Grodd, as Kreisberg revealed: "We have another [episode] in which Caitlin plays Fay Wray to Grodd’s Kong." Panabaker teased: "In season one you got to see just a tiny bit of her relationship with Grodd and you’ll get to see a little bit more of that and understand their connection from before. He has some unfinished business with her, I’d say."
