Human Nature
Paul Cornell
 Bernice Summerfield is grieving since the death of Guy de Carnac (as seen in the previous novel, Sanctuary). The Doctor takes her to a market on a planet called Crex in the Augon system. He quickly sets off, telling her he'll be back in an hour, and Benny finds a pub where she orders a beer and finds a group of female human drinking partners. After Benny's had several drinks with them, the Doctor arrives and places a patch on her cheek — a pad that disperses the alcohol in her system. He tells her that they need to leave immediately, and leads her back to the TARDIS. He hands her a scroll, tells her he'll see her in three months, and collapses. Meanwhile, the genesmith Laylock meets with his associates. They plan to follow the Doctor. In a long, dark room, a teenager named Tim awakens from a dream, having had a premonition that everyone will die. Unable to understand Benny's grief on a human level, the Doctor has purchased a device which alters his biodata, transforming him into a human named Dr John Smith. Smith lives as a history teacher at a public school in 1914 England, and falls in love with a fellow teacher named Joan. However, when alien Aubertides, hoping to acquire Time Lord abilities, attack the school, Smith sacrifices himself and becomes the Doctor once more; as the Time Lord, he is unable to love Joan in the way the human John Smith did.
