An upcoming episode of Arrow will preview more of The Flash’s new cast. Danielle Panabaker as Caitlin Snow and Carlos Valdes as Cisco Ramon will appear in Arrow’s episode 19, “The Man Under the Hood.”
In an interview with The Hollywood Reporter, Arrow executive producer Mark Guggenheim commented on the decision to introduce the characters prior to the premiere of the spinoff. “It allows us to further flush out The Flash universe in Arrow. We get to see their dynamic.”
While the circumstances of Caitlin and Cisco’s visit to Starling City remain unknown, we do have a few details about the characters themselves. Both work for S.T.A.R. labs, she as a bioengineering expert and he as a mechanical engineering genius. In the comics, Caitlin eventually becomes the villain Killer Frost but Cisco becomes Vibe, a hero who joins the Justice League of America.
Geoff Johns, Greg Berlanti and Andrew Kreisberg, who head up The Flash’s writing team, will pen the Arrow episode in which Panabaker and Valdes appear. The full pilot for the series about the Scarlett Speedster will air in October. “The Man Under the Hood” will air in April.
