Alan accompanies Chrissie to Andrea's birthday party. Remembering Maria's suspicions, he questions Andrea, who takes him to the attic and sorrowfully reveals the truth. When Andrea fell off the pier and Sarah Jane was unable to save her, a voice offered to switch the girls' places and Andrea, terrified, accepted. The figure appeared and gave Andrea the puzzle box, then removed himself from her memory; Maria's questions made Andrea remember the deal she made with the figure. Alan is now chased into the street by the Graske but he knocks it down, then uses its device to bring back Maria.
