Psychic gorilla Grodd is coming back to Central City to menace "The Flash" and the team at S.T.A.R. Labs in Season 2, it was revealed Thursday.
With his return, he'll look to settle some "unfinished business" with Dr. Caitlin Snow in particular, according to star Danielle Panabaker and showrunner Andrew Kreisberg, who dished details at a press event in Los Angeles.
"Caitlin plays Fay Wray to Grodd's Kong," Kreisberg teased of the non-human meta-human gorilla's upcoming return, referencing the 1933 classic "King Kong" film.
In Season 1, it was revealed that Grodd was a test subject at S.T.A.R. Labs, where he was experimented on and formed an early bond with Panabaker's scientist character. After the particle accelerator explosion made Grodd's psychic powers manifest themselves, he escaped the lab and sought shelter in the sewers of Central City. Ultimately, Caitlin, Cisco (Carlos Valdes) and Wells (Tom Cavanagh) had to turn on their former subject in order to save Barry (Grant Gustin).
"I think in Season 1 you got to see just a tiny bit of her relationship with Grodd," Panabaker added. "You'll get to see a little bit more of that and understand their connection from before. He's got some unfinished business with her, I'd say."
"The Flash" airs Tuesdays at 8 p.m. ET on The CW.
