"Fan out," Bella calls to her sister, and they take different directions through the debris. Bella has no supernatural senses to guide her, but she was very close on his trail and she is very fast and nimble. If she's wrong about where she's going Soph still has a shot at setting the guy on fire once they get into more open ground and the line of sight is better.
After a short time it may be obvious to those keeping pace that he's headed towards an exit towards the back of the building. Since the back is on the west side of the building, there's some shelter from the sun still. And, more relevantly, an entrance to the Sunnydale steam tunnels.
Bella makes reasonable progress towards the exit, trying to copy his steps.
"I'm out," she calls to Bella, "go on -"
And then she hops back to where Tamara and Kevin are supposed to be -
There's a Tamara here, at least. She's still on the ground sobbing, and trying to nudge a scattering of dust into a more coherent pile.
"Ta-" Soph stops, leaning on the wall. "-mara," she finishes, almost inaudibly.
And she finds a shortcut - there's a chain strung high across this path, high enough to be awkward to jump and heavy-draped enough to be hard to go under, but she has her shell knife; she cuts, she runs, she intercepts.
Tamara doesn't respond to Soph when she arrives. She's having trouble drawing breath already; it's sneaking up on her, the feeling from crying too hard and too long, and running out of air. She gently smooths the last of the dust into a tiny pile- so tiny- and stares at it helplessly. She reaches for it, and then draws her hand back. She- she's not sure what to do, now. Except cry, and see if she can still inhale, in this world that doesn't have her son.
It won't kill him unless she manages to decapitate him with it, but even a vampire will be distracted and less effective if he loses a hand.
Well, "loses". She doesn't have a lot of live-fire knife practice yet and doesn't make a clean cut through his arm. It's still attached, but pretty uselessly. So when she grabs it and yanks it finishes coming off, but throws off his balance in the process.
And then she clotheslines him and throws him at a different exit. On the sunnier side of the building.
She compromises with a hand on Tamara's shoulder, tentative.
Tamara shudders slightly when Soph puts her hand down, but doesn't object.
And sniffles.
And Bella strides out the door and stands over Charles and watches to make sure he doesn't put himself out.
Right then.
Back through the warehouse.
To the chair and the pile of dust and "Oh fuck -"
Bella flicks her knife out and cuts a furrow into the words until they're illegible.
She waits, a minute, before saying:
"Soph, can you fix your ankle or do you need to go to a doctor?"
At the reminder that they might leave, Tamara visibly tries to pull herself together. It doesn't work very well. But after a few gulps, she at least manages to choke out, "Soph, I- do you- a container?"
Bella goes. Bella comes back with an empty jar.
