Thankfully communicating with a train is not the strangest idea to Alice - who has spoken to a lot of much stranger things than a vehicle, honestly - so that part doesn't really stick out to her. Instead she thinks more about everything Aziraphale is saying as a whole.

"Hmm, I understand." Or she thinks so, at least, with that explanation. "It does seem like there isn't much progress in our situation."

Though she's used to that. It's kind of Wonderland's whole thing, isn't it.

"Even though some people seem fairly desperate to get off the train."
