Simon, a Robohuman, has asked the Doctor and Mel for help. Simon thinks he can dream, but the Doctor doesn't think it's possible. Mel tries to convince the Doctor that it's possible, and convinces the Doctor to investigate. The Doctor asks Simon to go offline for ten minutes while the Doctor looks at his CPU. The Doctor and Mel report to Detective Inspector Naylar, who informs them that Simon will be memory-wiped. He also tells them that Zang was actually a convicted serial killer.
