In the London sewers, the Doctor and Leela encounter a giant rat at least 10 feet in length. They make a hasty retreat. In the theater cellar, the doorman Casey and the manager Jayco investigate the ghosts Casey claims to have seen but find nothing. Jayco offers Chiang a new financial arrangement but Chiang clearly has special powers, given to him by his true master, Weng-Chiang. The Doctor explores the theater himself and comes across a projected hologram, which explains the ghosts Casey has been seeing.
