“Gorilla Warfare” is episode seven of season two of The Flash.
In the previous episode, “Enter Zoom”, Wells finally admitted, after Cisco saw her, that Zoom had his daughter, Jesse. Wells isn’t being manipulated by Zoom but that is why he wants to stop him. The trap set for Zoom doesn’t work and instead Zoom afterwards set his own trap. Barry attempted to throw lightning at Zoom, but the latter caught it and threw it back, and Wells attempted to hit Zoom with the serum he developed, but Zoom caught that as well. Zoom also broke Barry’s back and, if he hadn’t decided to parade the Flash around Central City first, probably would have killed him. Zoom’s grandstanding and return to S.T.A.R. Labs enabled Cisco to hit him with a dart, and Zoom fled leaving Barry behind. Barry, when he came around again, realised he couldn’t feel his legs.
Barry is now walking a bit with the help of a cane and Joe. Barry’s told that he has made progress, and he has. For in a week he has, according to Caitlin, almost completely healed from an injury that would have permanently crippled almost anyone else. When it’s suggested that Zoom may not be coming back, Wells says he highly doubts that. So he’s going to do something about it by going home to take care of Zoom once and for all so that no-one else gets killed. Caitlin tells Wells that if he can figure out how to stop Zoom on his world, he can do that here. She’s the only one who seems to want Wells to stay at the moment. Caitlin tells the others after Wells leaves the room that with Jay gone Wells knows Zoom better than anyone else.
Then there’s an alarm and Cisco says that it’s a meta-human attack. Then checks and says that it isn’t. It’s an alert for him that says ‘Date Night Tonight.’ Cisco announces that he’s going on a date with Kendra Saunders; dinner, a movie and maybe breakfast. Barry makes out he doesn’t know why Cisco suggests breakfast. Cisco may also be being overconfident. Barry also gets a call from Patty; he’s been telling her he’s sick. She offers to come around with her homemade chicken noodle soup, but Barry says not to and that he links the tinned – probably because he doesn’t want to have to explain that his ‘sick’ is actually ‘he’s the Flash and got his back broken fighting Zoom’ – which causes a bit of a problem when later when Joe tells Patty that Barry hates the tinned. Patty tells Barry to keep off his feet – not a great problem at the moment.
Caitlin goes in search of Dr Wells. He says that his plan was to get the Flash’s help to stop Zoom, but that plan failed and he has no other plan than to go home and fight Zoom himself. Even though that might be suicidal. Wells is trying to figure out which breach he needs to use. Caitlin tells Wells that he’s lucky Cisco and Professor Stein never figured out how to close the breaches, or he’d be stuck here. That gives Wells an idea; he says they need to close all the breaches bar one, giving Zoom only one way of getting through, and have that breach be the one at S.T.A.R. Labs. And set a trap.
Cisco is on his date night but, when he touches Kendra, he gets a vibe of a winged woman and rushes off, apologising a lot.
At Vaughan Pharmaceutical, a Dr Shaw comments to a tech about finishing for the night then suddenly gets a vision – a familiar one as it happens – and starts acting oddly. He breaks some glass and steals a canister from behind it before leaving the building. Outside, Shaw wonders what happens, then turns around and sees something. The something is Grodd, who hits Shaw pretty hard. Joe meets Patty at the crime scene the next day. She says she’s found some weird-looking hair and that this is the second lab tech to die in the last two weeks, so Joe asks her to see if they are connected. The canister stolen was a serum used to treat blood disease in the brain.
Barry, despite being fully healed, is still not running. This looks to be because his confidence has been broken by Zoom, along with his back. So Iris tells Joe they need to call someone to help and that someone is Barry’s father, Henry, who left town after being cleared of his wife’s murder in “The Man Who Saved Central City”. Henry turns up later to help.
Cisco is talking to Caitlin to see if she’s heard anything about the birdman he saw – he’s not observant; it really looked like a birdwoman – and Caitlin tells him that there is no such things as a birdman. Cisco believes a birdman isn’t really a stretch these days. Then Caitlin starts acting oddly and slugs Cisco before leaving.
Patty contacts Joe and tells him that the two lab tech deaths are connected. The first serum stolen was one used to treat patients with vertigo. Both are nootropic drugs used to enhance intelligence. There were hairs at both scenes too and Patty has had them analysed. She says they aren’t human and Joe says they were gorilla before she can. Joe rushes into the control room shouting that Grodd is back – Joe does not like normal gorillas; he really doesn’t like Grodd. Grodd has also abducted Caitlin,.
Cisco wonders why Grodd abducted Caitlin because she was always nice to him. That might be why. Grodd wants Caitlin’s help. He wants to know how he became intelligent – because he wants to make more like him. Looks like the giant gorilla is lonely.
So, they need to locate Grodd and then get Caitlin free. Then Barry turns and sees the Reverse-Flash – it isn’t, it’s Harrison Wells in a spare suit that Cisco found. Grodd considered Thawne/Wells to be his father, so the plan is, once Grodd is located, to try and convince that Harrison Wells is the dead Reverse-Flash.
