Arkady allows Ereuvir to handle his face. He's missed being touched. Ereuvier's hands don't feel like those of a mortal's. They aren't cold like a corpse or a statue, but there is a certain chill to them. It's not really a physical chill, but more the feeling of being touched by someone that embodies death itself.

To anyone else, the touch would be unnerving and creepy. But Arkady doesn't move to pull his head away or give any indication that he wants it to stop.

At Ereuvir's words, Arkady catches that little hint behind the phrasing. "You already piqued my curiosity, and yet you dangle another little bit of bait before me. I'm finding it harder to refuse."
