"Castiel?" Anna says quietly, after a long period of silence.

Castiel looks up from his book. "Hmm?"

"How did he know what you looked like?"

Castiel doesn't have to ask what she's talking about. Michael and co. left hours ago, but Castiel suspected this would be coming soon.

"He saw me," Castiel says. "I almost caught him once, and he saw me."

"But you didn't catch him?"

Castiel shakes his head. "I didn't even realize we were close until he told me."

"How did he tell you?" Anna asks, confused. "How do you chat with a serial killer?"

"I don't think I'm allowed to tell you any of this," Castiel says.

Anna frowns. "The guy almost killed me, and I can't know anything about it?"

Castiel hesitates, then sighs. There she goes, making him guilty. That's what a good little sister does.

"He wrote my name on a wall," he says, purposely omitting the part about it being in blood. "And he kept leaving phone numbers and asking to talk to me. So I did."

"You listened to a serial killer?"

"There were extenuating circumstances," Castiel says vaguely. "He never tried to hurt me or anything. He said he liked me." The closest thing to a friend he's got.

"That's actually just as creepy as him not liking you," she says. "I guess it makes sense, though."

"What?"

"He tried to save me so you'd be happy," she says.

"Yeah, that didn't really work," Castiel says.

"But it's better than me being dead," Anna says. "I mean, I'd hope you'd rather I be in the hospital than in a grave."

"Well, yeah, obviously, but still," Castiel says. "I'm definitely not thrilled with him."

"But he tried," Anna says. "He saved me."

Castiel shakes his head at her. *I don't know what type of weird Stockholm syndrome thing you've got going on, but he tried to kill you. He doesn't get brownie points for anything." And, if all goes well, Castiel won't ever see him to give him any, anyway.
