'Good people are self-torturing' is the kind of thing you believe if you're not particularly good at torturing Good people. You can hurt them way more than by making them realize they harmed the world, actually. 

Okay at this point you should leave, the point has been made and you're upsetting Alexeara.

Alex is a big boy, he can handle it. "Like our wise Count Cerdenya, I do not want Valia Wain to be tormented with the knowledge of her failure and her determination to set it right. I want her to be tormented with the severing of her tendons and the gouging-out of her eyeballs."

"Please, and the futility of her determination to set it right. She'd hardly be tortured at all without that!"

"As for the eyeball-gouging, that lacks elegance. It lacks panache. Anyone with eyeballs can have them gouged out. What's the point of a punishment that isn't specific to the victim? It's hardly poetic at all."

Lisandro will grab his delegate and his familiar and Teleport out, the only thing to do when one finds out Lilia Ramona de Montero is paying personal attention. Especially if she is already talking about gouging out eyeballs. He does it even as the baby anarchic adventurers are facing the consequences of their doomed charge. He'll regret leaving them behind for the rest of his life, but the other option is regretting it for the rest of his life and the rest of his afterlife. He hates the fact that he fled when Andoran had their revolution for the same reasons as why he's doing it today, but does not actually hate himself enough to face malediction.

If she flaps her arms like a fucking bird can she fly down — apparently not — why isn't anyone doing anything—

Because she just tried to commit murder on the floor of the convention.

If she actually does anything he can smite her. But not for - minimally violent self-defense -

"Poetry? You misunderstand me, Esquerra. I am not a poet. I am a busy woman, who spends all her time in the diligent service of her country, and has a few scarce hours for enjoyable hobbies like torturing Iomedaen priests to death, and I wished to commend the Count Cerdenya on his diligent work to enable this hobby of mine; the discussion of what forms of torture are most artful I have had a thousand times, with better artisans than you, and such matters of taste are in any event not the remit of this convention."

"Thanks to the fine work of the armies of Rahadoum, Paraduchess, there are no better artisans than me."

There's someone who wants her to drop Victoria. She's spent the last several moments wrapping spells around herself - heroism, invisibility, alter self - before her dart flies out. She's not the best at throwing weapons in the world, but she's got pretty good aim normally and with all her magic and song up she can reliably hit a person in half plate through the gaps in their armor.

It doesn't hit Montero, and she doesn't even have the decency to dodge or let it skitter off magical protections. Displacement? 

"Now, now, girls. Iomedae considers bravery a very important virtue but you will notice she did not at your age run to Gallowspire to throw sticks at Tar-Baphon."

Go sit down before my fiance murders you. 

He's too principled. ...and I have a contingency.

She's a Calistrian, not an Iomedaean, and if Iomedae thinks people shouldn't try to kill Evil Asmodeans who tortured hundreds of innocent people and are planning to torture your best friend then Iomedae is wrong.

...She casts the spell that makes it harder for Lawful people to hurt her. Unfortunately this does not actually stop her from being in the air.

He doesn't usually attend the floor sessions anymore, but the Archmage's day off is a good day to have an invisible eighth-circle wizard with permanent arcane sight and glasses of true seeing watching the proceedings. The Lilia Ramona de Montero who just spoke is, as several people have already guessed, an illusion. The surprising part is that she's a sixth-circle illusion cast by an allegedly third-circle wizard.

He's only seen the face of the true Lilia Ramona de Montero in sketches and by reading the minds of others. (The illusion's face is different, but that's unsurprising.) He didn't know it well enough to immediately recognize a younger, presumably Reincarnated, version of her. Given another reason to contemplate a connection between Montero and the Duchess of Chelam, however, he absolutely does.

Message to Cansellarion: It will take time to confirm it, but I have strong reason to believe that's the actual Montero, and that Carlota de Chelam is and has always been a false identity.

(He starts casting Discern Location. Under normal circumstances he would expect her to be long gone and/or Mind Blanked by the time it finishes, but Chelam can't do either of those things without arousing a fatal level of suspicion.)

("Out, Mateu," she says when Lisandro vanishes, and the archduchess and six people disappear from the line and arrive in Kintargo, leaving three more staff to back away slowly and flee.)

We're saving that plot beat for mainline threads and so, somehow, Third Alex doesn't get the message.
