Nine nights worth of visions. Well, eight, really. After which... anyone in the vicinity of the Forbidden Forest, or on the way to Hufflepuff, might run into a pale, exhausted, faintly traumatised-looking man carrying camping equipment. Feel free to try to engage him in conversation, or ask what the hell happened. If you're feeling helpful you might try to make sure he gets a drink of water or something to eat, since he obviously needs those, not to mention a shower.
That's what he's going back to Hufflepuff for, of course. And, then, he's going to bring his cat home.
