On the one hand, Blai seems to have some sort of weird issue with making the kids strong enough not to be worthless. On the other hand, he did seem to realize that bringing a bunch of weaklings up to the surface was a bad idea. And she's sure he's stronger than Hosilla, so even if she did help Hosilla out, it wouldn't actually do anything. On the third hand, he said he'd accept surrenders, but it sounds like he wouldn't even be taking her as a slave, he'd just be... trying to make it so she doesn't go to the Abyss? For some reason? Maybe as some sort of surfacer punishment?

"I no longer serve you, you bitch! Not you, and not your flying monkey! Blai is stronger than a worm like you could ever be."

And she looses an arrow at Hosilla.

Why is he on first name terms with some sort of triple-crossing not important right now. Fighting now. Burst of Radiance in case she needs her eyeballs.

She did need those!!! Why does this guy have so much annoying light magic!!! (Also, in case there was somehow any doubt, she is in fact Evil.)

In the absence of her eyeballs, she will summon a dretch instead.

Archers are happy to shoot at her! (Lann's aim is worse than normal; he keeps shooting glances at Wenduag. His face is screaming at her VERY LOUDLY.)

Non-archers will run in after him.

The dretch is annoying but Hosilla is the priority and he's flanking with the boar for the remainder of its existence.

Then he will eventually manage to kill her. She gets off one good blow with her glaive, mostly by luck, but she's kind of flailing.

The dretch focuses its Stinking Cloud on the archers in the balcony; it goes down a couple moments after she does.

Are the mongrel kids standing down?

They are huddling near the aasimar's corpse. One of them is retching. The crying one is still crying. 

That is adequately like standing down. He motions everyone into the radius - even, he supposes, Wenduag - for a channel.

The party will cooperate with this. 

Lann is still glaring at Wenduag.

Channel: done.

"Do we need to attempt amateur mediation of whatever that was," Blai says with a significant look at Wenduag and a glance toward Lann, "or can we proceed to the surface."

"What I want to know," Lann says icily, "is whether she's been luring our people to do... this."

"I was trying to make them stronger. I kept the real weaklings away, the ones who wouldn't have survived it."

"Make them stronger by luring them to a demon and forcing them to eat an aasimar."

"I never forced them to do anything. Every last one of them had a choice." She points at the dead mongrel. "If they wanted to go to their precious crusader gods instead of becoming strong enough to defend the tribe, none of us ever stopped them."

He briefly considers "do you have anything less profoundly idiotic to say" but that's really more of a thing to say when you are a) in actual command of the situation and b) also maybe Asmodean, he's not sure if it's orthodox to talk like that.

Instead he'll go with: "If people made choices just as well under threat of death then it wouldn't be such a popular method of coercion."

"I'm glad they gave me the chance to be strong."

"You—"

"What, Lann, do you think I should have just died? You think it's better to just lie down and accept your fate?" Snort. "There's a reason I never brought you here."

Presumably collaboration with demons is a crime in Kenabres and he will simply have two people to turn over to the inquisitor. "Your behavior is appalling, weakens the collaboration which has at enormous cost kept the entirety of Golarion from falling prey to the demons, and will almost certainly cost you access to a tolerable afterlife. I recommend you spend what time remains to you coming to a state of mind that will be at all defensible at trial, which description I believe does not correspond to anything you just said."

Wow, she knew he was probably going to be kind of pathetic about this but she didn't realize just how bad it would be. 

"If the demons are strong enough to win, then they deserve to."

And she makes a run for the stairs.

"Qualm."

—Huh, he said it in a really stupid way but maybe he kind of had a point? If everyone turned out like her it would've been a great plan, but a lot of them turned out to be weaklings who couldn't control themselves and basically just attacked anyone they saw. Maybe she should talk it out with him, see if she can explain things better this time?

She slows down.

Sounds like it'll be a lot easier to shoot her, then.
