Charlotte continues her investigation, discussing time travel theories with Robert Mercier, a professor from her alma mater. Armed with his input, she invites Jack for their second interview at her favorite Italian restaurant. There they have lighthearted discussions about pizza and cheesecake, and Charlotte begins to quiz him about how his time traveling really works. Jack has an answer for everything, explaining his jumps through time with technology analogies like blockchain and big data. He is unrelenting, and to prove his point, makes a wildish claim about how he and Charlotte came to meet.
