The cultist easily restrains Oswald.

Yeah he's going to get between Oswald and Anemone because she's already hurt and very frail and right now this is very salient and he's blatantly compartmentalizing but that's okay he can deal with all of the everything later.

Lacie smiles and claps her hands. "I am sure my brother will calm down soon. It was a shock to me too, the first time I saw our God."

Oswald struggles ineffectually against the cultist. 

"It's all right," Lacie says, her eyes shining. "Everything's all right. I know so many things now."

IT'S REALLY VERY MUCH NOT

"Our God is so beautiful."

Mostly trying to think about how the fuck she is supposed to get Lacie out of here since she's not dead so Anemone can't leave her but she's also not going to cooperate and augh maybe she should leave her?? Oswald's not going to go for that and they're not going to be able to get in like this again after Trammel gets back and ugh ugh ugh

He breaks free from the cultist and then collapses on the ground.

"Lacie--" He's averting his eyes from the Thing on the wall. He sounds exhausted. "Lacie, are you okay--"

"I'm better than okay. I'm chosen." Her face looks like she is staring at the Divine itself. "My Lord won’t rest until the whole of the human species drinks of his Nectar… sinks to his debased depths… mile-wide mouths swallowing human beings by the dozens… drowning whole cities in Nectar. And I will be His Queen. His Child. His Beloved."

Gotta play it cool. Gotta play it cool. "I'm so happy for you, Lacie."

"The Daughter of Nyarlathotep."

He crawls over to her, reaches out as though to touch her. He doesn't seem to be registering anything except her presence.

She lifts Oswald to his feet. "Join me, brother. You can serve Him too, just like Samson and I. He will teach you so many things... so many secrets..."

ahahahahaahah FUCK

Mordred, on the other side of the scale, is 100% onboard plan "leave Lacie since she's clearly not on team 'save the world from this thing' anymore and book it." Convincing Oswald of this will be a challenge, but. (He's not thinking about whether he'll need to convince Anemone. Obviously Anemone will agree that leaving as soon as humanly possible is the sensible thing to do, because she is very sensible.)

He leans into her, holding her tight, his head on her shoulder. "I thought you were dead," he whispers.

"I'm alive. It's like I've never been alive before."

There are five cultists and one Lacie and someone has opened the trapdoor to the library, but it's on the other side of the cellar from the investigators.

"I'm so glad." He is registering the tone but not the content, particularly. "Come back with us. I was so lonely. I missed you so much."

"No, brother, stay with me. So we can be a family. You and me and Samson, together at last... the heralds of the heralds of Azathoth..."

Mordred is painfully aware that if he tries to argue for not bringing Lacie with them on the grounds that bringing cultists around is hazardous to their health he will be the world's biggest hypocrite. Fortunately Lacie does not seem especially interested.

She's mostly thinking about how fucked they are right now. Maybe they can talk their way out still. She can't really fight her way out. And she doesn't think she can convince Lacie to leave although she doesn't know what's up with Lacie.

"I don't want to just leave you here-- please, Lacie, come with us and you can tell me all about it-- I just want you there with me--" He's crying a little. On some level he knows this isn't going to work.

"I want you there with me too, Oswald. We can have that. Samson can show us so many things..."

Having SUDDENLY REMEMBERED that Carrie was taken after having forgotten in all of this horribleness, she is going to... look around and see if she can spot any other areas of the cellar where someone might be hiding Carrie, since apparently she's not with the Mouth?

...man she sure hopes it didn't eat her.

They do kill people in other ways, they carry bodies out sometimes...
