Harry, Cisco, Joe and Barry talk about Grodd in the cortex. Barry is still down on himself in the wheelchair as he doesn't have his speed. Joe tells him that his brain wasn't affected.

Caitlin wakes up and has no idea where she is. She then hears Grodd and is surprised when he mentions her name. He then approaches her and says that she was always kind. He tells her that he needs help and asks about how he became who he is. She then says that it was due to the dark matter explosion. He then tells her that she needs to repeat Grodd and that she must learn.

Barry is on the treadmill at Star Labs trying to get his speed. He powers it down when his dad shows up. Iris had brought him.

Harry comes up with an algorithm to find Grodd.

Henry and Barry are discussing how he must slow down to get where he wants to be. Cisco interrupts and they head to discuss what the plan is. Harry is to dress as the reverse flash and head to find Grodd. Barry is stuck behind with his dad and they discuss how his body is healed. Barry however is worried that the city didn't believe in him, to which Henry said he could relate.

He approaches Grodd and talks like the other Wells before drugging him. Caitlin and Cisco rush out.

Harry is patched up by a thankful Caitlin. They talk about how to get rid of Grodd. Harry mentions how they should get Grodd to enter one of the breaches. Henry says that Flash will do it.

The flash then shows up and Grodd pounces down at Flash. Barry has flashbacks to Zoom before Caitlin tells Grodd that he needs to trust her to give him a home. Getting Grodd into the circle, Barry speeds Caitlin out of the way so the breach could suck Grodd up. Henry tells Barry to conquer his fear to stop Grodd from getting free. He then speeds off and pushes Grodd into the breach. They then close it behind the gorilla.

Afterwards, Barry and the others try to destroy the reverse flash suit but not before figuring out how to shrink his suit into the ring. Harry offers to help.

Kendra is closing up at Jitters when she spots Cisco outside with a picnic basket as an apology. She likes it and he tells her about being a liaison to the CCPD and that was why he had rushed out on their last date. She ends up kissing him and he gets another vibe of her. This time it was because he saw her in a hawkgirl costume. When asked, he claims it was due to the kiss.

Grodd lands in a forest like area. He sniffs and walks and in the distance spots many gorilla statues.
