Dylan's eyebrows raise and lower at the mention of one of them potentially becoming a vampire, not sure he would have even considered that if this were his problem, and not because he wouldn't have thought about it, period. Living forever isn't really something he's interested in, whatever the reason. He can understand, though, why that might be a choice, even if it wouldn't be his, which is why he doesn't comment.

Instead, he rakes his tongue over his teeth, before, "You know, the Eye's got an archive."

The magical equivalent of the Library of Alexandria. Hell, some of it was probably salvaged from, all things considered.
