Back upstairs!  More waiting around!  She passes time in mostly the same ways but now she can also think at her leftover magic, which is kind of like having someone to talk to except for how it isn't really.  It's a better conversationalist than like, Cleverbot, though.  And doing that lets her notice pretty immediately when the relevant thing stops being aversive.

What happens if Alassëo swears to swear that a particular thing is true and then that particular thing becomes false; she'll try a couple different scenarios in that vein.  And obviously he should still be far away and have no reason to expect that she'll ever learn about his reaction.

He will... collapse in agony until Cam figures out what's going on and stuffs his mouth full of caramel, apparently.

Disturbing!  She ends the vision pretty immediately on a flinch reaction and then has to wait most of a day to look at the rest of it because apparently starting these up is more costly than keeping one going, at least for the first while.  She checks variations intermittently until it's time to go downstairs and then she does that.

Cam is actually not in the main bar at this time, though his stuff still is. He walks in through the back door presently.

"Hi.  I think I believe oaths exist now."

"Oh, good. Should I call Alassëo over?"

"Yeah, if you don't mind."

Cam opens the door again, summons Alassëo, holds the door for him.

"Hi.  If you want to swear to things now I'll probably believe them."

"I'm not sure what in particular you stand in doubt of. I have not lied to you, I so swear."

"If you could go over everything that happened to the best of your knowledge and then swear you haven't lied, or attempted to mislead me, or left anything out that you'd expect I'd want to know.  And then - a character reference for Cam.  If you would."

"Everything that happened in - the war?"

"Yup."

"...I have some of the songs about it memorized but the songs sometimes bend the facts to suit the scansion. I can try to put it in my own words for you." He collects his thoughts a bit, and then explains the leadup to the war, with where he learned anything he didn't witness himself (most of it) included. He pauses after using the word "evil" and then operationalizes that (mass murder, forcible uploading, horrific torture, compelled reproduction) before going on to use the word without elaboration after all.

And he'll swear to that?

After he has explained the whole war with an emphasis on Cam's part in it (specifically noting that Prince Nelyafinwë trusts him and the King is understood to have consulted on the text of the oath) he will swear that's his sincere understanding of the situation!

"Okay.  Thank you and - I'm sorry."

"- what for?"

". . . All?  Of that?"

"Oh. Thank you."

She nods.

"I think that will be all, thank you, Alassëo."

Alassëo nods to him and goes back outside.

She stares down at her lap for a few moments.

"Do you mind if I still check some stuff about you."

"Like what?"

"I'm kind of worried you could like, steer, somehow, if you knew specifically what it would be."
