In the episode, Snakeskin's real identity is revealed to be Ms. Scott, the school's guidance councilor who one of the heroes has a crush on. Snakeskin hates popular kids because of her past experiences of being bullied. She therefore plans to detonate a bomb at a party filled with poisonous snake venom.
