SPOILER WARNING: This article contains spoilers for "Untouchable," the latest episode of "The Flash."
It looks like "The Flash" is headed on another inter-dimensional journey. In the last scene of "Untouchable," the latest episode of "The Flash," Jesse Quick returned to Earth-1, desperate for help. As it turns out, Earth-2's Harrison Wells is in trouble -- in Gorilla City.
Over the course of the episode, Wally attempted to learn how to phase. Much to his frustration, he couldn't pick up the ability, despite the fact that he's been so quick at learning his other abilities. When push came to shove, however, he managed to pull it off. He needed to use his speedster blood in order to neutralize Clive Yorkin's decaying powers, though he couldn't touch him. Nevertheless, Wally managed to deliver his blood -- and thereby the antidote -- by phasing through Yorkin.
Wally was practicing his new power when Jesse arrived. A portal formed suddenly in STAR Labs, only for Jesse to come speeding out of it. Wally was immediately glad to see her, but Jesse obviously had something else on her mind. As it were, her father Harrison is in trouble -- but what kind of trouble, she didn't say, though she did mention that it had to do with Gorilla City.
If Gorilla City sounds familiar, that's because it was introduced in Season 2. When Grodd attacked Central City (again), Team Flash disposed of him by sending him to Earth-2. That is to say, Cisco vibed him right into Gorilla City, a settlement filled with sentient gorillas.
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.
