"Cool School" is the fortieth episode of Season 2 of Teen Titans Go! and the ninety-second episode overall. It first aired on 23 April 2015 on Cartoon Network, marking the two year anniversary of the series.
Rose Wilson escapes from prison, defeating the Titans with cool one liners. Only Raven is immune to Rose's insults, and the two decide to hang out and do cool stuff together. Cyborg, Starfire and Beast Boy feel lame by comparison, so they go to Cool School.
At the Jump City Juvenile Correction Facility, an inmate has escaped her cell and retrieves her weapons. She comes across the prison guards, who order her to return to her cell. The inmate defeats the guards and throws one against the wall, which crumbles away to reveal the Teen Titans. Robin identifies the prisoner as Rose Wilson, also known as Ravager and calls the Titans into action. When he says "Go," Ravager adds on "away," stopping the Titans in their tracks. Beast Boy is shocked that Robin's catchphrase is being used against him and Robin retorts that Ravager should go away. She tells him that was the plan and tries to leave through the hole in the wall until Robin stops her. He calls the Titans into action again (but adds that anyone who says or tries to say something after his catchphrase is a dummy), but Ravager uses insults to hurt the Titans' feelings and defeat them. Raven finds Ravager's one-liners enjoyable and shoots several back at her. They both think that the other is cool when Beast Boy asks why Raven isn't taking her down. She says she thinks Ravager seems cool and Cyborg and Starfire say that they're cool and begin to cry once Raven says that they're not. Ravager and Raven decide to go hang out and Raven lies to Robin, saying they're taking the long way back to Ravager's cell.
At Titans Tower, Ravager and Raven are hanging out in Raven's room. Ravager is admiring Raven's prisoners and compliments the darkness of her bedroom while Raven compliments Ravager's swords. She reveals that her father gifted them to her, but calls him lame. Raven shares about her dad problems, calling them the worst. Ravager notes that Raven hates things and she responds that she likes to hate things. Ravager says that she likes that she hates things when Robin enters. He sees Ravager and tells her that she's supposed to be in jail. Ravager claims that she is, but Robin yells that she isn't as they're in Raven's bedroom. He calls for Raven to tell her and Raven backs up Ravager, saying she's in jail. Robin says that saying she's in jail doesn't mean she's in jail and Ravager counters that saying she's not in jail doesn't mean she's not in jail. Raven backs up Ravager again and once the villainess says that visiting hours are over, Robin runs off in frustration.
On the couch, Starfire is petting Silkie and wondering if Raven was correct when she said they weren't cool. Cyborg says that they shouldn't care what Raven thinks, but Beast Boy says that he cares and Cyborg admits that he cares as well. The three Titans begin to cry until Cyborg resolves to go to Cool School. There, the professor sings a song where he teaches them how to be cool. Meanwhile, Raven and Ravager are walking down the streets of Jump City when they come across a music shop. Ravager asks Raven if she wants to jam, but Raven notes that the store is closed. Ravager slices the door in half and says that it's open. Throughout the night, the two play instruments, ride on a motorcycle, play games at a booth, carve a tree to mock Robin, dance, and post pictures on DCUbook. While Raven and Ravager relax on a bench, Robin jumps out of a trash can, determined on proving that Ravager is not in prison but in the city. However, Ravager simply says that it's a big prison and he can't see the walls, frustrating him further.
Back at Titans Tower, Starfire, Cyborg, and Beast Boy celebrate their newfound coolness. While getting tacos, Ravager asks Raven if she wants to see something cool. She throws a knife at Sticky Joe, who happens to be eating tacos. Raven remarks that she almost hit him, and Ravager decides to throw another knife with her eyes closed, retorting that she doesn't care if he gets hurt. Raven manages to catch the knife with her soul-self, saying she isn't gonna let her hurt Sticky Joe and the two begin to fight. Ravager easily gains the upper hand and their battle escalates to the rooftops where Raven is thrown against the wall. Ravager prepares to kill Raven, but Robin and the other Titans appear on the rooftop. Ravager insults their clothes and Cyborg reveals they went to Cool School. She says that Cool School isn't cool, but that dead people are and attacks. She manages to defeat the Titans and throws them against the same wall as Raven before raising her sword and asking if they have any uncool last words.
Starfire tells Raven that while they're not cool, they are true friends and that is what ultimately matters. Her sincerity hurts Ravager and she dubs Starfire's statement corny. Robin theorizes that because Ravager is so cool, earnest emotions will hurt her. Cyborg hugs Raven and tells her that she has always been like a sister to him, hurting Ravager with affection. Beast Boy tells Raven that they think she's the bee's knees and transforms into a bee, hurting Ravager with the cuteness of it. Robin tells Raven that the Titans are simply trying to say they love her and Ravager begins vomiting as they participate in a group hug.
At Jump City Juvenile Correction Facility, Ravager is behind bars once more and she shares her disappointment in Raven. Raven brushes this off while Robin celebrates that Ravager is finally back in jail. Ravager claims that Robin is also in jail, frustrating Robin who claims her wordplay won't work on him. Ravager says that Robin sounds like someone in jail and he tells Raven to tell her that she's in jail. Raven glances between Ravager and Robin and says that Ravager is in jail.
