Now that Lee lost his key to a council member, Lee and Biffy attempt to go to the casino called, The Hydra, after school to confront him but are caught by Barrage. Cam, Biffy and Holger go to The Hydra in Lee's stead. The council member, referring to himself as "The Serpent", is the owner of The Hydra. They are tricked into a series of games for the key; if they lose they die. Tina finds out about the bugs. Lee, Tina and Jenny find that the council is trying to look for the book, but they manage to hide it. The three of them follow the three present of the five council members to the pyramid, realising that Barrage is being controlled. After losing, the Serpent offers to let Biffy, Cam and Holger live if they answer questions about Lee's age, birthplace and tattoo None of them know of the tattoo's origins. Ultimately they find that the Serpent has already given the keys to the council. The council's attempt to unlock the pyramid fails and the pyramid zaps a female council member, the Woman Dressed in Black, who falls into a coma and a deep sleep, like the teacher in the detention room, and they decide the book has the key to unlocking it properly. Lee intends to wake up the detention teacher and find out what happened.
