SPOILER WARNING: This article contains major spoilers for "Welcome to Earth-2,"tonight's episode of "The Flash," which has not yet aired on the west coast at the time of publication.
Barry (Grant Gustin), Wells (Tom Cavanagh) and Cisco (Carlos Valdes) took a trip to Earth-2 in tonight's episode of "The Flash," and as these things tend to happen, it did not go according to plan. The major developments from "Welcome to Earth-2" included meeting Cisco's Earth-2 counterpart, Reverb -- possessing powers advanced far beyond "our" Cisco's current levels. Which could be good news for the Earth-1 version.
"I feel like once you're exposed to something that's possible -- it's like the first time Tony Hawk did a 720 on a skateboard, everyone could then do it -- and so once Cisco saw the magnitude of the power he's capable of, anything's possible now in his mind, and we may explore that," "Flash" executive producer Aaron Helbing told reporters at a press event this week at The CW's Burbank headquarters.
Yet Reverb won't exactly be able to tutor Cisco -- he's killed in the episode by Zoom. Though anything is possible in the world of "The Flash," it doesn't sound like a return is likely.
"I think for the purpose of where we want to take Cisco, having [Reverb] die there was the best way to get what we want out of the character," fellow "Flash" EP Todd Helbing said.
Reverb wasn't the only Earth-2 doppelgänger introduced in the episode, which also included the debut of Killer Frost (Danielle Panabanker as the evil version of Caitlin Snow familiar to comics readers) and Robbie Amell as Deathstorm, a dark take on Firestorm. On top of that, Zoom imprisons Barry, leaving the hero of the show in peril as the first half of the two-part episode -- which concludes next week with "Escape from Earth-2" -- ends.
