So they're more or less from the same time. That's a relief. Clarisse doesn't have long to think about it, though, because—

"The graveyard?" Times she's thought about the Deerington cemetery before this moment: approximately zero. "It's probably just some creepy ambiance thing. I don't even know why Deerington has a graveyard. It's not like anybody stays dead here."

Maybe it's for the townspeople. Although who knows what happens to them when they die, because Clarisse doesn't think the townspeople are really human at all. She can't put a finger on what that would make them, exactly, but all she knows for sure is that having to interact with them manages to both skeeve her out and piss her off, and she does it a little as she can get away with.
