"Admitting that only makes you question your taste," he mutters, though there is quiet amusement there. He stills as sharp teeth graze his lip. It's impossible not to notice them, especially since he's had Astarion's mouth all over him by now. But those teeth had never been a threat and so he'd looked past them. Wondered, but not enough to bring it up. He can't decide now if he's glad that he didn't, or if it would have given Astarion the opportunity to share all this sooner and thus relieve him of the burden he's been carrying.

"How have you been feeding yourself?" he asks, almost absently - a matter of curiosity (for now) rather than deep concern. Obviously Astarion is finding a way. "Animals?"

Fenris assumes Astarion hunts for the same reason he does, only the parts of an animal they need to survive are a bit different.
