Talking about his character Sheldon, Jim Parsons says that he [Sheldon] had left "very distraught," with all the changes in his life. He adds that the "train trip did not go as planned ... I don't know if there was a plan. It didn't go well." Mayim Bialik (Amy) says that Amy's feelings get hurt, but it is typical Sheldon, Amy relationship. "There is a lot of misdirection."

Parsons jokes that Amy and Sheldon's relationship is the healthiest relationship in the show and that it has a lot to do with the fact that a contract is involved. Bialik adds, "And, no sex, as that complicates everything." Parsons agrees to that.

Simon Helberg (Howard) talks about Stuart's presence in Mrs Wolowitz's house. Helbeg says that Stuart is playing too many roles for Howard to feel comfortable about it.
