Victor grows frustrated with Sibuna and concocts a scheme to put a stop to their quest. He secretly releases mice in the house to give him a reason to search the bedrooms. He searches and finds the elixir and some of the students’ proof. He also finds the panel in the attic that conceals the picture of Sarah. While this goes on, the students must spend the night at the school. Under the guise of needing to place the order for a take-away dinner, NIna and Fabian lure Trudy and Mr. Sweet into his office and lock the door. Victor is forced to abandon his search of the house in order to go and let Trudy and Mr. Sweet out. Nina and Fabian sneak back to the house to take the other puzzle pieces before Victor gets to them. When Victor arrives at the school, he informs Mr. Sweet that his door was locked from the outside and wonders if Nina and Fabian had anything to do with it. Nina and Fabian make it out of the house just in time to escape being caught by VIctor and run into the delivery boy outside the school, providing the perfect explanation for their disappearance. Nina then tells the other members of Sibuna that the remaining puzzle pieces must be carried with them at all times and to protect them with their life. Jerome catches Alfie with his puzzle piece and steals it to give to Rufus. Amber convinces Mara to petition the teachers into allowing an end of term prom.
