[Stiles wonders how his dad would react to the idea of vampires being a real thing when he's only recently started accepting the idea of things like werewolves and kitsunes. He chews his thumbnail, shrugging a little at Dean's skeptical look. Mythology and theories surrounding it are weird sometimes. But it's not like asking Jerry will pan out to be very helpful.

He's not even sure the mirror thing matters that much except it bugs him and he wants to know why the vampire doesn't have a reflection.] There's also a theory about most mirrors containing some kind of silver in them but I kinda doubt that applies here either.

[The question that Dean asks next makes his face pale a little, especially when he adds the explanation for the question. Though he wonders if it's really all that different from what Derek had done once upon a time back home with Erica and Isaac and Boyd.]

Yeah. They're fine. They didn't turn and they're not dead.
