Something Ventured, Someone Framed

When a new member of the Human Appreciation Society, Mattholomule, challenges Gus' leadership, Gus invites Luz to the society's meeting, lying about her ban being lifted. The school is now enforced by trouble-smelling creatures working as security guards following Luz's last visit. After thinking over Luz's desire to attend magic school, Eda reluctantly visits Bump about enrolling her into Hexside. He surprisingly agrees, believing the school could learn from having a human exchange student, on the condition that Eda fixes every prank she pulled when she attended Hexside. Mattholomule has Luz taken to detention. Gus then gets himself and Mattholomule detained as well, and detention is revealed to be a giant pit with worm creatures that entrap and brainwash students into good behavior. Luz and Gus rescue Mattholomule from the pit and escape just in time to run into Bump and Eda. Gus takes the blame for everything, and Bump removes him from the H.A.S. as president and member altogether, being replaced with Mattholomule. Eda tells Luz that she is allowing her into Hexside because she knows that she's smart enough to make her own decisions, and Bump agrees not to tell the Emperor's Coven about their deal.
