.. why was the Slytherin prefect bringing professors ice cream?

Not that Alice was particularly bothered by it. Just.. why? Kissing up, perhaps? Would it get her more house points if she started bringing snacks to her instructors from now on, too? She seriously considered it as she slipped into her regular Divination seat by Ascanius and greeted Elwood. "Hi, prof. I assume you're well and all. Especially now that you have ice cream. Unless you don't like ice cream."

Or the flavor of ice cream that Duck Boy had brought her. Which was what, exactly?

Psh. Duck Boy. If he got the wrong flavor, any proper professor would nick points, Alice knew.
