For the Spuffy fen...
‘Shadow Puppets’ issue 1 gives us what four issues of s8 haven’t.
Spike is weighing the options for and against going to Japan and taking out the new Smile Time puppets:

See? One line: ‘What if there’s an impromptu reunion with the Slayer while I’m away?’
It doesn’t stop him from going. I doubt she’ll be mentioned *at all* in the story to come. I *expect* Spike to hit on every hot-looking girl he comes across (and sleep with them if he can). But - we know that he thinks about Buffy. He might not imagine that he can actually ever have a future with her, and he might not ever try to look her up, but he does dream. She’s a part of his world, of his hopes for the future, whether those hopes become reality or not.
And none of this in any way compares to Buffy’s threesome fantasy. *That* was about sex - and heck, she had fantasies about sex with Spike before she slept with him. It tells us nothing about what she thinks or feels for either of the vampires in question, beyond the fact that she’d like to sleep with them again (and that she’s horny. That she loves them I’m taken as understood). Does she miss Spike? Mourn him? Does she even know he’s alive? Does she ponder a reunion, even if she’d not actually seek one out? We don’t know.
One line. One line is all it’d take. I don’t need a resolution, I don’t need a meeting or buckets of tears. Actually I'd really dislike buckets of tears. All I want is an acknowledgement that Spike matters(/mattered) to Buffy.
And what have I got? Buffy misses Teh Sex. *sigh* I much, much prefer the Buffy who’s dating The Immortal. At least she's getting some.

no subject
Is she?
"I miss my mom. I miss the gang. And churros. And sex. Great muppety odin, I miss that sex. [...] Outstanding. I can't even feel sorry for myself in a linear fashion. Suck it up, Summers. You're a big girl now."
She's worryingly isolated. She can't even have a one night stand to scratch that itch, since the only male around appears to be Xander. I'm not saying that Buffies *not* stuck in Scottish castles are any happier, but they can at least snuggle down on their sofa with a pizza, a tub of icecream and a bottle of wine and watch telly for a whole night. Does this Buffy even *have* a sofa?
Compare and contrast with Spike (from 'Shadow Puppets'):
"Lately I've been working alone. And to tell you the truth I am bloody loving it. I've played sidekick to far too many people. The girl was fun. She let me be the dominant one now and then. But after years of playing by other people's rules, it's bells and whistles being on my own. The angels over my shoulder are gone, baby, gone."
There's more, but that gives you a good idea. Sure, as we later see he wouldn't mind Buffy turning up at all, but mostly - Spike is in a good place. He's living his life his own way, has set up his own agency and keeps a little flat (with a nicely large TV and much nicer furnishings than his S5 place). If there's anything missing from his life, then it's something he's prepared to live without.
All of which again has something to do with the stories having different focus etc.
