Detentionaire

The episode picks up where the previous left off, the pyramid opens revealing symbols.

When Lee escapes after being attacked by Hazmats, the Pyramid once again triggering his martial prowess as his tattoo glows, the Council arrives to take Finnwich after he blows up the pyramid, so they can never know its secrets, killing Cassandra's brother, who refused to run, in the process and hides his book and device for Lee to retrieve. Meanwhile, Biffy escapes the falling aircraft, Holger believes he has superpowers (in this case, enhanced stealth abilities and X-ray vision) after waking up from unconsciousness in the detention room with Jenny, Cam and his group attempt to find out whose fingerprint was on the letter and later Tina is freed by Lee. After they all meet up, Tina and Jenny study the book with the device, and Lee, Biffy and Holger proceed to find Finnwich. The boys find a hideout where they see Finnwich, Lynch and the female council member are carried to a submarine to be taken to Coral Grove, where the Council sends people who "know too much".

After witnessing the submarine exit the hideout, Lee, Biffy and Holger decide to leave.

Lee manages to defeat The Serpent by exposing him to his allergy: fish. Cam shows up to help Biffy and Holger only to find that Lee, Biffy and Holger had just escaped.

The episode ends with The Serpent printing photos of Lee's family, seemingly oblivious to Biffy's phone camera set up in the room.

The episode begins with the Serpent gathering things used by the Ping family as they sleep. In Tina's room, while respectively trying to access the files of the Coral Grove website and decipher the book, Tina and Jenny admit to each other their feelings for Lee, worrying them about its possible effects on their new, close friendship and resulting in them competing to impress Lee with their findings throughout the day. In the early morning, Lee has a nightmare about choosing between Tina or Jenny. Holger calls Lee about a dream in which Lee is crushed by a giant chicken at 9:30am. At school, Cam finds Grayson running away from him, but he is called into the Mr Wurst's office as he pursues. Barrage arrives and gives Lee, Biffy, Tina and Jenny detention for being seconds late to class. When Cam tells Mr Wurst about him cheating, Barrage arrives and expels but Wurst insists he is principal and Cam will only be suspended. Wurst and Barrage literally fighting over who is principal and the appropriate punishment. Cam gets Lee and Brandy to find Grayson and turn him in, causing Tina and Jenny to think they're back together, but Grayson escapes. During this, Brandy confronts Lee about his love triangle with Tina and Jenny. Meanwhile, a man supplying chicken for the staff arrives in a chicken costume, causing Holger to attack him. After Wurst and Barrage call a truce and compromise, they suspend Cam and strip him of his presidency. Brandy chastises Lee for not confessing his feelings to Tina, calling him a 'big chicken', and he enthusiastically runs to tell her. Meanwhile, Tina deduces a way to identify which files on the Coral Grove site are about which inmate. Tired and afraid of their love rivalry, Jenny suggests a pact that neither of them ever date Lee for the sake of their friendship and themselves, as Lee is seemingly with Brandi again. Tina agrees right before Lee arrives and privately confesses to her. A horrified and crying Tina turns him down as he's too late and r

Jenny's bike gets stolen on her way to school and she accepts a ride from the Serpent. The Serpent sets up a lice outbreak at the school by putting a infected helmet lice on Jenny. At school, Biffy tests Holger's claims to superpowers for his own amusement until Kimmie points out his hypocrisy, while Lee struggles to cope with Tina's rejection by obsessively monitoring the feed of the Serpent's office. The phone's charger is dislodged by the Serpent's snake but Lee finds photos of his family in the office when the camera is moved before the battery runs out. Meanwhile, Cam spends his time watching cable TV during suspension but starts to miss school. Beth, a mathlete, is the new school president as she was the only other candidate (other than Lee) in season 1 but starts to annoy students because of her selfish policies, abuse of power and obsession with wizards. The Serpent appears at the school to get a sample of Lee's hair during the outbreak's screening process. Lee, Biffy and Holger pursue him throughout the school but he escapes, giving Jenny, who is now smitten with him, another ride. During their webcam conversation, Cam suggests the Serpent's gathering of things from Lee's family is related to cloning, or perhaps the Serpent is simply a fan. The episode ends with the Serpent scanning Lee's hair, getting a positive DNA test and discarding Biffy's dead phone. As he looks out towards the city, he declares "I finally found you".

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.

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.

Brandy tells Cam the "Glamazon Vote", where they vote for a leader, is today and turns down his offer of help due to his reputation declining after losing his presidency. Biffy figures out a way he and Lee can figure out if cloning teachers is taking place: talking to the the 15th Graders. The 15th Graders build Beth a trebuchet for her, due to Chopper being attracted to her. Biffy pretends to set up a date after school for Chopper in exchange for some information, some photos of a teacher's weight fluctuations further convincing them of the cloning. Lee and Biffy decide to go to Brandy's apartment building to find the teachers. Brandy has trouble with the vote as the other two Glamazons are too dim and afraid of Kimmie to be persuaded to vote against her. Kimmie subtly tells Brandy she's onto her and Cam eventually goes out to Brandy's place to help. When Lee and Biffy get to the building, they are invited into Mr. Langhorne's room but are knocked out by gas when Langhorne goes to lie down. After waking up to find Langhorne gone, they cover their mouths, lie on the bed and find themselves in a chamber with sleeping teachers in pods. After touching one of them and turning him to dust, activating an alarm, they climb back out. Kimmie is voted the leader again, Cam arriving right after voting ends and Brandy is kicked out of the Glamazons for voting for herself and insulting Kimmie afterwards. The episode ends with Biffy hypothesizing all the teachers may be clones. Lee realises what he is implying and denies his mother is a clone. Biffy points out the recent evidence: they saw teachers in the pods, Langhorne's room smelled like the staff room and the Taz stole the file on Sue Ping. Lee jumps on his parents bed to prove that his mother is not a clone, with nothing happening.
