HELLO, I FRICKIN' LOVE VAMPIRES and hoo, boy, Lucas is a not-zombie from the land of not-zombies (and actual zombies) - while he'd present a lot of it flippantly (and, well, think about it flippantly, because nearly every god-damn thing is a game to him), finding out that there's a vampire about wouldn't weird Lucas out, but it would have his curiosity!
On snackin', meanwhile, he wouldn't volunteer to get chomped on, but I can see him at some point... drawing a bit of his own blood (he's got a high pain tolerance and regenerative abilities, so yaaaay) and offer it at some point to "see what would happen" if he thought about the idea enough to get curious for the sake of it, seeing as he's... diseased, suffice to say. (If that did happen, it wouldn't be communicable via him, of course, but it would taste pretty disgusting.)
