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. (thetvdb.com)
