She is, in fact, going to be okay, right? Alter-Pilar would definitely be okay, so that's who Keltham saw, confident in her faith. But real-Pilar should also be okay. She's already been through her trial in Elysium. If there was any flaw in her faith, for all this art and technique to find and crack her through, the Elysians would have used that against her already, right...
...unless they didn't pick it out on purpose. Because they were not, in fact, actually trying to convert her away from Asmodeanism, just then.
Pilar will find her way to somewhere near Subirachs's office, just in case she is less invincible in her faith than she thought, and requires either sudden spiritual guidance, or a Sleep spell to put her out long enough for Aspexia Rugatonn to get there and correct her in a matter of faith.
