"Give me a description of them."

Judging by the context, one might almost assume that Alice is making a joke.

But her voice is too straightlaced for it. She sounds entirely serious about this.

"I'll give them an earful, the moment they appear on the train." Is she totally ready to go yell at someone she doesn't even know? Oh, absolutely. Gladly. The more outlets she has for her temper, the better, in fact.
