Harry’s (Tom Cavanagh) love for adventure has put him in a very dangerous position.

At the end of Season 3, episode 12 of “The Flash,” Jesse (Violett Beane) arrives on Earth-1 with the news that Grodd (voiced by David Sobolov) has abducted her father in Earth-2 Gorilla City. But what was Harry doing in Gorilla City in the first place?

In a recent interview with TVLine, Violett Beane revealed that Harry was actually invited by some of the sentient apes to visit Gorilla City for a meet-up, and because Harry was looking for a thrill, he decided to go to the forest with some men as companions.

“Jesse’s dad got a message from some of the sentient gorillas, who asked to meet him — as gorillas do — and you know Harry, he loves an adventure. So he mounted an expedition and took 10 people into the forest with him,” Beane shared.

And because Jesse hasn’t heard from her dad for a long time since he started their journey to the forest, she comes to Earth-1 to ask assistance from Team Flash. “She is very scared for her father, so the team starts to help her find him,” the 20-year-old actress said.

When asked what fans can expect from the first installment of the Gorilla Grodd two-parter, Beane said: “It’s going to be pretty massive. There’s a battle between Grodd and his own gorilla friends. … There’s a stampede, and there’s a huge gorilla fight towards the end of the first episode.”

Those action-heavy moments pretty confirmed what executive producer Aaron Helbing told Entertainment Weekly about the two-parter last month. “There are some sequences in the two episodes that are unbelievable. They’re epic and unbelievable in scale and scope. I’ve never seen anything like it on television,” Helbing said of the multiverse arc at the time.

“The Flash” Season 3, episode 13, titled “Attack on Gorilla City,” airs on Tuesday, Feb. 21 at 8 p.m. EST on The CW.
