Ari patrols most nights. He frequently whistles as he does so. He's on friendly terms with many of the people of the town, though some of them think he's a dangerous weirdo. (They're not wrong, but it's not very polite to say it outright like that.)
Vampires still come to Sunnydale. Because it's Sunnydale, and because vampires are idiots. The ones who live here already, though, have picked up a habit of either visiting the kosher butcher's or the bite shop, or moving to LA. Or having their heads ripped off by an excessively cheerful blonde half-Kal'shekk witch.
Speaking of the kosher butcher's, he pops his head into that alleyway. Maybe he'll see Mr. Ray, that nice vampire chap who comes by for some fresh cow's blood every Thursday. (Ari acts cheerfully oblivious to the fact that every vampire he knows is blind terrified of him. Some of them are alright when he keeps them from eating people; being unrepentantly amoral doesn't have to mean you're not a nice person.)
That's good, because short of involving crowbars or putting a stadium airhorn up to his ear, no force on Earth is going to remove this man.
Mark can think of some other options. (He rather wishes he couldn't.) But he likes Ari, so: snuggles.
Snuggle, snuggle. Hey, he doesn't even have to make excuses for not having slept when Ari wakes up: he's a vampire, he sleeps during the day. Which this isn't.
Ari smiles in his sleep, it may be noted. He's as happy when he's dreaming as he is the rest of the time, but with less interference from the varied unpleasantnesses of the world. He dreams himself adventures and battles and fair maidens and/or princes, the last of which is probably fairly obvious at the moment.
Ari would probably object to Mark's choice of words, were he awake and aware of them. As it is, he continues being adorable.
Ari sleeps until about noon. When he wakes up, he is (as always) a bit fuzzy around the brainpan.
"...Maaark? Mark. 'morn'n."
"Dreamed 'bout saving you from... dragon," he mumbles conversationally.
"Mark, can I please fix your misery hole? Crypts should be cheerful, homey places. This looks like somewhere you'd put dead people."
"It is somewhere you'd put dead people. There are in fact dead people in it, even if you don't count me." He gestures to the coffins in their alcoves. "What exactly do you want to do to my misery hole?"
"Make it pretty and less miserable, and possibly give you a spacious basement in which to put depressing corpses. Corpses are a secondary function of crypts at best."
"Suit yourself. I'm not attached to the current architecture. I might rather put me in the basement and leave the corpses where they are, though. They've been here longer than I have."
He touches the wall and hums, drawing power from the earth. This is going to be pretty big; making the bird was a fiddly little job, but this is going to be broad strokes and heavy lifting. Earth power's cooperative, though. Probably won't be any trouble.
The wall shivers as the cramped ceiling of the crypt warps and begins to glow. After a few minutes, it's gone from gloomy, claustrophobic eaves to a nice spacious dome that sends a gentle natural light through the (still mostly horrible, but now a bit cheerier) crypt.
Ari looks contemplatively at the corners of the room. "Can I just do the vacuum tornado trick, or do you object to spider-killing? Should I relocate them to the woods instead?"
He shrugs. "Well, spiders are useful for getting rid of other bugs, but I'm not moved to defend them for their own sake."
Ari then peeks under the lid of a suspiciously generic coffin. It turns out to be empty. "Do you want the entrance inside this coffin? Hides it a bit. Plus it's cool."
Ari grins, puts his hands on the coffin, and pushes with his stoneshaping. There will be stairs, leading down, the earth will compress into stone and the stone will compress into itself because he is of earth and stone, he is strength and solid form and stability. Slowly, but speeding up as he goes, the rock and dirt cooperate.
It'll take him something like fifteen minutes to get the basement dug out.
