[Prefect is usually pretty good at throwing the towel in, in fact he has a tendency towards being fairly accommodating, but if there's one thing that he hates more than anything in the world? It's change. He didn't like having Sam assigned to him, and he really, really doesn't like that he might be losing him, so impossible is a pretty good word for him right now. He tilts his head, then turns slightly.]

Fine. You can stay here as long as you want.

[This said, Prefect makes for the door.]
