The TARDIS materializes, rescuing the Doctor as Skagra drives off with the sphere. Romana helps the Doctor, but he's furious to learn Chronotis is dead. In his study, Chronotis’s body vanishes as the Doctor and Chris discuss losing both the book and the Professor. Romana and Chris recall Chronotis’s warnings about Skagra and Shada. Clare, attempting to warn Chris about the book, decides to visit Chronotis herself. The Doctor’s group traces the sphere to a field and encounters Skagra’s invisible ship. Inside, Skagra forces the Doctor to read the book, using the sphere to extract his mind. Romana, Chris, and K9 are trapped, but K9 detects the Doctor’s voice among the sphere’s signals. Skagra captures Romana and uses the Doctor’s key to access the TARDIS, leaving the Doctor, who pretends to be dead, to manipulate Skagra’s Ship into releasing his companions before it shuts off his air supply, causing him to suffocate.
