[After so long without any word from Buffy, Angel's taken it upon himself to check her room a second time for anything he might have missed before that could help clue him and the rest of her friends in to what's happened to her--or what kind of loss she's on, if his and Willow's assumption is correct.
Being a vampire, the whole stalking into people's bedrooms when they're not around, or when they're sleeping and watching them like a creeper is pretty much second nature. This time around he notices something that slipped past him before. What looks to be a small box is partially hidden beneath the bed. Considering it would be sort of hard to believe that it rolled under there from the desk or nightstand, it strikes him as more than a little out of place.
When he lifts it up, the bottom drops open and out pours
this happy little melody. What strikes Angel most when he rights it in his hands is the resemblance that the slowly spinning ballerina has to Buffy. It's not hard to put two and two together from there. Setting the music box onto the desk, he flips open his journal to relay the news to anyone who still might be worried and wondering about Buffy's disappearance]
I think I know what's happened to Buffy. It looks like the castle turned her into ... a music box.

For anyone who knew Kahlan Amnell, she's been sent back home.
