MacCauley's discussion with the conductor was so deep and meaningful (Spoiler)

I don't know who you are. I don't know what you want. If you are looking for a ticket, I can tell you I don't have any money. But what I do have are a very particular set of skills, skills I have acquired over a very long career. Skills that make me a nightmare for people like you. If you let the train go now, that'll be the end of it. I will not look for you, I will not pursue you. But if you don't, I will look for you, I will find you, and I will sue you.

Really let me know how much he wanted to go home, that did.
