Joyce Summers agrees: I love it when you agree. Haha. And I can definitely see the Spike-Smirk thing. Most likely followed by Buffy blushing and ordering him to stop looking at her that way.
Here's how it could go, then:
Spike: "Slayer.
🙂:Slight head nod. :
🙂 Slayer Junior."
:: Spike tilts his head and does the funny little smirk/raised eyebrow thing. ::
Spike: "Interesting company you keep there, pet."
Buffy (blushing): "Do NOT look at me like that. I'm serious, Mr. I'm-Back-From-the-Dead-but-Forgot-to-Call!"
Spike: "Yeah, well, I was a little busy, what with being in Hell and all. Monsters to slay. Neighborhoods to co-Lord. You know how it goes. Seems you were a bit on the busy side yourself."
:: Angel's eyes widen as understanding finally dawns. ::
Angel (gasps): "But what about the cookies?!"
:: Everyone turns to look at Angel. ::
:: Angel folds his arms across his chest and mopes (I mean "broods). ::
Angel: "I meant metaphor cookies. It's a thing."
Spike: "I told you we should have locked her in a box."
Buffy: "You *what?*"
Spike and Angel (quickly): "Nothing!"
