He doesn't expect that to get a reaction. Forever isn't such an unusual turn of phrase. He's never had to avoid it to keep away suspicion. The only people who might pick up on it... he's looking a little more carefully now, scrutinizing her, a little more aware of her pale skin.

"Forever," he confirms, straight faced. Maybe he should try and pass it off as a joke. Instead he remains serious, a hand drifting up to the faded scars on his neck only half subconsciously. Though the movement's instinctive there's a curiosity in his eyes as he runs his thumb over old bite marks. Is she? Would she recognize them for what they are? Part of him would like to hope, but out of all the supernatural creatures he's encountered it's vampires he's most wary of.
