Inspired by (surprise!) Surprise and Innocence. Buffy is feeling kind of empty since the change, like there’s a void inside of her that isn’t filled. She’s longing after what used to fill the void, and is wondering why it isn’t there (and all in 5 short lines....now THAT’S talent!)

Filled with need,
Filled with longing,
Filled with lust.
Yet an empty shell without Trust.
Why did you betray me?
