Fans already knew that telepathic ape supervillain Gorilla Grodd would return to "The Flash" in its current second season -- and now it's been revealed exactly when. The CW has released details for "Gorilla Warfare," the seventh episode of "The Flash" season two, airing Nov. 17 and featuring the return of Grodd.

GORILLA GRODD RETURNS TO CENTRAL CITY - Grodd returns to Central City and kidnaps Caitlin (Danielle Panabaker). Barry (Grant Gustin) and team race to find her before it's too late. Meanwhile, Cisco (Carlos Valdes) plans his first date with the new barista at Jitters, Kendra Saunders (guest star Ciara Renee) and Patty (guest star Shantel VanSanten) begins to suspect Barry is hiding something from her. Dermott Downs directed the episode written by Aaron Helbing & Todd Helbing (#207).

Both "Flash" executive producer Andrew Kreisberg and main cast member Danielle Panabaker have previously discussed Grodd's imminent return, with Kreisberg saying Panabaker's Caitlin will play "the Fay Wray to Grodd's Kong."

"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," Panabaker said. "He's got some unfinished business with her, I'd say."

Given the character's nature -- a megalomaniacal talking gorilla with telepathic powers -- Grodd was generally considered to be an unlikely character to be seamlessly adapted into live-action, but "The Flash" teased an appearance since its very first episode. The character was featured in full in May's "Grodd Lives," aiding the Reverse-Flash.

"Gorilla Warfare" is scheduled to air 8 p.m. Tuesday, Nov. 17 on The CW.
