“Him,” by Drew Z. Greenberg
Xander is showing his apartment to a potential roommate... one who turns out, a moment later, to be Spike. This may be the single most self-sacrificing thing he’s ever done for Buffy or the world, and I’m talking about a guy who offered to let Willow kill him.
Spike knows he’s not wanted and tries several times to volunteer himself out of the homesharing gig. But Buffy is determined to get William out of the school basement. His proximity to the Bidet of Evil is clearly one of the reasons he spends so much time jabbering. She is okay enough with having feelings for him that she wants him to get better.
(Or, maybe, she’s that tired of having to parse useful clues out of the babble.)
As they process this, Dawn asks a fabulous question: What does it mean exactly, that Spike is all soul-having?
