Clay and Nicole are up next, with Nicole asking questions about Clay's wife. Nicole gets through the questions really quickly and then goes through and repeats all the questions and answers back to Clay. I guess that's how she got through medical school. We don't see Nicole's answers to Jon's questions, but the train pulls up and the doors open, so she must have got them right.

Now Mark is asking questions about Nicole's mother, but he's asking them really slowly and Nicole is kind of freaking out. Jon asks Mark the questions, and then the train pulls up. Nicole is giggling because her mom is talking to herself and they can't hear her. The doors open and her mom runs out. Aw. This is sweet.

Clay asks Mark questions about his wife. Mark interviews that this is the longest he's gone without seeing his wife since they've been together. Jon asks Clay the questions, and Clay draws a blank on at least one. As the train pulls up, Jon says that one of the questions he asked was one that Mark couldn't answer, so Clay had to get three out of four. The train stops, and Mark's wife runs out. Aw, and she's pregnant and has to take care of their three kids alone. I hope Mark is having fun.

Paul is the last one to play, and Mark asks the questions. Paul skips a lot of questions, and Mark is kind of nervous that he'll be asked the questions that were skipped. I wonder if the quiz is to give the answers that Paul gave, or to give the answers that his wife gave? The train pulls up with Paul's wife and adorable little girl inside and I will actually be sad if the doors don't open. Not because I like Paul, because I don't, but because I feel bad for his little girl, who can see her daddy but can't understand why she can't go hug him. Aw. I just bummed myself out. Oh, thank God. The doors open. The cutest part is that Paul's daughter points at the door and goes "Open sesame" and the doors open at that moment. Everyone gathers and Jon tells them that they added $50,000 to the pot with his mission. Mark interviews that he doesn't think that even The Mole would sabotage that mission.
