Alcuin for his part was surprised, but slightly less horrified, in part because he could tell that - whatever the reason - Kersen's intrusion was an accident. And also he wasn't particularly embarrassed by sex. He allowed Aaron most of the blanket, settling into a sitting position with a small amount of it in his lap. (He did think that Aaron's covering himself was pretty funny, as it wasn't as if Kersen hadn't seen him naked before.)

Kersen kept his back to them though, so it didn't really matter. "I - I heard two vampires in the bar talking about how their hive had captured a priest. I thought he fit your description and you weren't answering your phone, so I - the door was unlocked."
