I'm morbidly pleased by the subliminal jousting that these two are doing. It was simpler in the novel, Sharne being deceived by the Devil in a tutor's attire. But here, Ayrin is actively trying to navigate through their conversations perhaps to chip away at his facade...
It felt that way, at least. Ayrin is 100% aware that death & malice incarnate is sitting right next to her and I love it
