Andrew eats with Isobel and tries to find out if Gulliver told her anything about the Riemann hypothesis. Isobel tells him that all Gulliver said about the night he disappeared was that he had come home late. Meanwhile, Andrew notices subtle differences between Isobel and the other humans he’s met so far. He sees how deeply she looks at things and notes how she dresses. Andrew helps Isobel load the dishwasher, which shocks Isobel, who has always carried the domestic responsibilities. Then they receive a phone call from Daniel Russell. Thus begins the end of his mission. Daniel asks about his health, then references the email he received. The two men agree to meet up in person to discuss the email further. 

Isobel tries to drive Andrew to Daniel’s house, but he insists on going alone. He finds the address in their address book and goes to Daniel’s house, which is exceedingly large. His wife, Tabitha, answers the door. She asks Andrew how he’s doing, and Andrew tries to find out if Tabitha knows about the reason for his meeting with Daniel. She says she doesn’t, then gives Andrew a glass of water and discusses Daniel’s health.
