You consider not going with Gordon, but he convinces you. It doesn't take much effort. The train ride is slow and uncomfortable. Gordon asks about a joke you made earlier, and you tell him that it wasn't actually a joke. Not in the traditional sense, anyway. It's only a joke to you because it happened to you, so you get to find it funny. Everyone else just gets uncomfortable, but that's part of the humor. Gordon asks more questions, but you don't want to answer. There's pressure for a bit, ending only when the train comes to a halt.
