They don't go to the car immediately. Dean sits down on the picnic bench, and opens up one of the pie boxes, ready to start stuffing himself, when they're interrupted by a girl's voice.
"Hey, you're the Winchesters, right?" Sam and Dean both look up sharply, Sam's hand flying to the demon knife, Dean…protectively hovering over his pie? Sam gives his brother a bitch face, and Dean looks a little sheepish.
"Who's asking," Sam says. The girl grins—she's a ginger, green-eyed, about sixteen. Her clothes are those you'd see on a street kid.
"I'm Annie," she says, "and I'm a demon." Her eyes flick black, then, and Sam's hand closes around the handle of the knife and Dean has long put down his pie. Why did every moment of peace have to be ruined by something like this?
"Whoa," she raises her hands. "I'm not here to like, kill you or anything. I'm on your side."
Dean snorts, and Sam's eyes narrow. "Like Ruby was on our side?" Dean sneers.
"Uh, Hell no." She giggles. "Ooh, punny. But seriously, no. She was such a skank. I would never try to seduce Sam Winchester."
Sam and Dean just stare at her. What kind of demon is this?
"Every girl you sleep with dies," she says after that, and Sam can't help but wince, just a little.
"Not all of them," he protests, and Dean just glares.
"Look, this is fun and all, but the hell do you want with us?" He growls. The demon sighs.
"You really forgot me, Dean—I mean, Dad? Hello, I'd've thought you'd remember your kids—you remembered Alastair, after all."
Sam's confused, but Dean's face goes through an interesting series of expressions—first confusion, then pale horror and ashen comprehension, and finally settles on bone white.
"Dean?" Sam asks tentatively.
"Lily-Anne James," Dean chokes out.
The girl smiles like a Cheshire cat. "Bingo!" She claps.
