Oh, wow! Yes, I'd say there's lots more to mine in the scenario, and that you've barely started on the Spike-deals-with-being-human issues.

I especially love Spike's panic at Buffy's coldness (physical, this time), his oatmeal love, and Xander underplaying the situation ("grocery run") as is the Scooby way.

I know this is too soon, because you’re not really healthy yet and you’re human now and maybe that’ll change, you know, everything.

Boy, is she right that it's too early! But there's not exactly time to waste, is there? This is about as far from "happily ever after" as you can get, but who's to say that "happy when we can manage to fit it in" isn't a worthy goal?
