Know-It-All: [gets up, points to the Hero Boy] He did! The Conductor: You! [He comes to the Hero Boy] The Conductor: In case you didn't know, that cord is for emergency purposes only! [He comes to the window, train whistle blows and closes the window] The Conductor: And in case you weren't aware, tonight is Christmas Eve and in case you hadn't noticed: This train is on a very tight schedule!

Hero Girl: He was just trying to stop the train, so that kid could get on! [Conductor sees that Lonely Boy sitting alone in the next car] The Conductor: I see. [to Hero Boy] The Conductor: Young man, is that what happened? [He nods] The Conductor: Well... Let me remind you: we are on a very tight schedule. [he checks his watch] The Conductor: And I've never been late before and I am certainly not going to be late tonight! Now, everybody, take your seats! Please! [Everyone sits down] The Conductor: Thank you.
