SPOILER WARNING: This article contains major spoilers for "Attack on Gorilla City," the latest episode of "The Flash."

In "Attack on Gorilla City," the latest episode of "The Flash," Barry took Cisco, Caitlin and Julian to Earth-2 to rescue Jesse Quick's father Harrison Wells. However, it didn't exactly go as planned; Team Flash was captured, and it was all due to the machinations of Gorilla Grodd. After all, there's only one way Grodd could get back to Earth-1's Central City: with Cisco's vibe powers.

Grodd developed an elaborate plan in order to draw the Flash and his friends to Earth-2. He captured Harrison Wells so that Flash would return to rescue his friend. Naturally, Grodd was waiting and used tranquilizer darts to sedate his otherworldly prisoners.

Because he and his friends trespassed on the gorillas' home, the Flash was forced into battle with Solovar, Gorilla City's leader. The Flash won the battle, which opened the doorway for Grodd to take over as leader. Since Barry's role in Grodd's plan was over, Grodd shifted his focus to Cisco, who has the power to open breaches between world. Fortunately, though, Team Flash was able to orchestrate an escape by pretending Barry had died.

Cisco may have slipped through Grodd's grasp, but he isn't the only metahuman in the multiverse with vibe powers. At the end of the episode, Gypsy makes a grand reentry. She appeared with Grodd on the dias of the Gorilla City Colosseum. However, it's unclear at this time if Gypsy is working with Grodd of her own volition or if she is being controlled by Grodd's telepathic powers, as she didn't speak.

Though Gorilla City is new to “The Flash,” it certainly isn’t new in the comics. Introduced in 1959’s “The Flash” #160, Gorilla City has long been a staple of Barry Allen’s world. In fact, Barry — and later Wally — have managed to find friends in Gorilla City, including Solovar. Since Gorilla City is so new on the TV series, it’s doubtful that Barry will find any friends if and when he shows up there in the next episode. However, he could develop a rapport with someone over course of the next two episodes.

Airing Tuesdays at 8 p.m. ET/PT on The CW, “The Flash” stars Grant Gustin, Candice Patton, Danielle Panabaker, Carlos Valdes, Tom Cavanagh, Jesse L. Martin and Keiynan Lonsdale.
