Amber and Nina find a black cat which has escaped from the cellar. Amber pretends that she is sick and takes the day off school to look after it, but it disappears while she is asleep. Patricia persuades Nina to go and meet Rufus to show him the pendant but when they get to the meeting place they witness Victor kidnapping an apparently unconscious Rufus, which makes them suspicious. Sibuna lets Patricia in on the secret, and debates the possibility that Victor might be drinking an elixir that gives him eternal life. They decide to use the school play to try and expose Victor. After finding evidence of sinister experiments in the cellar, they turn to Trudy for help; she forces Victor to open the cellar only to reveal that he has moved everything. To the house's horror, Victor fires Trudy.
