Revenge of the Cycle Killers Detentionaire : Season 4 Episode 5

The episode begins with the Serpent's exposition to the audience instead of Lee's, during which he states he is one of the greatest warriors, has his own mission apart from working with Cassandra and now has all the facts. Lee and Biffy are told by Barrage to burn all the lice-infested furniture in a fire on the field. Lee and Biffy notice that two teachers look a lot like Benjamin Franklin and Mark Twain, making them revisit Cam's clone theory. They ask some jocks to dispose of the furniture and proceed to investigate. Meanwhile, Jenny and Tina meet the Serpent again and they hang out as Tina gracefully leaves them alone, thoughs he is alrmed when Jenny leaves on his motorbike again. He takes her to the woods and leaves her as a storm hits to investigate something in the bushes. Cam is dealing with suspension/being grounded as his little sister bugs him. During the day, Cam has flashbacks of himself being bullied in the past. After being forced by his sister to watch a horror movie with her, Holger arrives to take care of them. Lee and Biffy find files stating that the teachers were born on the same date, February 29th, a leap year, just like Lee's mum. As Biffy finds that the teachers all live in the same condo as Brandy, Lee finds his mum's file but the Tazelwurm arrives, steals it and throws it in the fire. As a surprise, the Serpent arrives and gives Jenny her bike back after it was lost and they go on a ride together to make up for him leaving her afraid. Grayson arrives at Cam's place to apologize for blackmailing him and the others for bullying him when they were younger. Though Cam never actively partook, he seemed to accidentally contribute as every prank on Cam was reflected onto Grayson even worse. At home, Lee video chats with Tina about what happened that day, neither realising it was the Serpent who met Jenny. The episode ends with Tina, upset that she can't further her relationship with Lee due to the pact.
