Team Flash is back home safe on Earth-1 but the fight for Central City is far from over. At the end of this week’s episode, we saw that Grodd (David Sobolov) had taken control of Gypsy (Jessica Camacho) and is going to use her to get back to his world. Barry (Grant Gustin) is going to need all the help he can get in order to defeat an army of super-strong, telepathic gorillas.

Next week’s episode of The Flash looks like it has the potential to be the best of the season. This photo gallery has something for everyone: WestAllen, QuickWest, Vipsy, the Wells family, a speedster team-up, a viber team-up… Oh, and did we mentioned The Flash of Earth-19, aka Accelerated Man (Sean Poague)?!?!?

The trailer for the episode shows Barry, Wally (Keiynan Lonsdale), Jesse (Violett Beane), Harry (Tom Cavanagh), and Joe (Jesse L. Martin) gearing up to take on Grodd and his army. King Kong has nothing on this ape.
