Apparently the vampire slayer has been attacking some large rocky-looking white thing that is not a vampire, and it flung her through a window into what fortunately turned out to be a mattress store. She's regrouping, but the thing is advancing on the broken window now. The state of the sidewalk suggests that crossbow bolts just bounce off.
That has an effect.
The thing's featureless white surface begins to disintegrate at the point of impact, releasing wisps of white smoke and an unearthly wail. Cracks spread across the creature's body, and it falls apart into multiple pieces, and the pieces into smaller pieces, and the smaller pieces into smoke, and when there's nothing left of it but a fading cloud the scream finally stops.
"Well," remarks Miles. "That was more dramatic than I expected."
"I'm trying not to add to the list of things I'm going to be disappointed in myself about forever, and letting you get killed would definitely belong there."
"Do you happen to have a few hundred dollars I can borrow for a plane ticket to South Africa?"
"I spend a lot of money on crossbow bolts and for some reason Slaying is volunteer work, sorry."
He shrugs. "Don't worry about it. Well, unless you find the prospect of petty theft worrying."
"A little, but it's not my job to police and you're not going to blow it on cocaine. Can I interest you in a mattress shop that looks like somebody may have broken into it?" She hops out the gap in the window.
Bella ignores Zeke in favor of the glass in her arm. "I don't suppose I can borrow that ray gun."
"If I had two, I might give you one, but this is my only nerve disruptor and anyway I really don't think we have a sufficient foundation of mutual trust for me to successfully teach you its safe and proper use."
"Point and shoot will probably get you as far as successfully killing things you wanted to kill. It won't get you as far as not killing things you didn't want to kill. Plasma arc training accidents are more memorable but I've always hated the nerve disruptor ones more."
"There might be more of these and my stupid powerset does not seem to give me anything with which to kill them."
"I don't yet have the funds to fly to South Africa anyway. I can stick around long enough to help you out," he offers.
"Okay, where do I find you if I learn these come in swarms?"
"I've been coming by that butcher's shop back there pretty reliably just after sundown. If it's urgent - Zeke, can I tell her where you live?"
"Look, I don't kill vampires because I'm racist, I kill vampires because they eat people. You seem to be not eating people, good job, me knowing where you self-entomb will not affect matters."
