[The fun to be had when worldstate circumstances leave the initial possession happening close enough to Vigil's Keep for the right people to see the immediate aftermath soon enough to figure A: it was him and B: it seemed very likely he was possessed. Katherine doesn't know by what, exactly. After all, it was a battleground, which means death. And lots of death meant, well...a spirit healer working his magic in an area with a weakened Veil would have been a prime target. (Not that the truth would come entirely out of the blue; she'd heard Nathaniel suggest that very idea to Justice once.)

But this, this is new. Katherine stares at the screen, taken aback. For a moment, her mind stumbles over itself for an answer. Possession shouldn't interfere with memory, should it? Connor had no memory of his possessed moments, but he knew what had happened before them, and this can't be Anders's possessor she's speaking to because that's...not the reaction of a demon meeting its host's friends for the first time. A demon trying to blend in would try to play along. ...Right?

In the meantime, while her brain is scrambling, her mouth isn't faring much better:]

Um...Anders? I know you can't be from before we met- in Amaranthine anyway. I mean, even then you recognized me from the Circle!

[Though, now that she's brought that to her already-rushing mind, how had he recognized her? With the torment the Circle was to him, her relative privilege within it had to have been frustrating to see.]
