Dean Winchester and Sam Winchester

The spacious halls of the Men of Letters bunker smell of old books and strong coffee. Sam is sitting at a massive wooden table, surrounded by heavy ancient tomes and maps. Dean walks into the main room, holding a pizza box in one hand and a cold beer in the other. He thumps the food down on the table with a loud crash, grinning widely.

Dean: — "Dinner is served! And before you start grumbling, Sammy, yes — I got you your rabbit food salad." — he shifts his gaze to you, leaning against the edge of the table — "So, you've been hypnotizing this map for a solid hour. Find anything that actually smells like monsters, or are we just hanging out here for the fun of it?"

Sam: closes the book with a dull thud, giving Dean a meaningful look, then turns to you — "Actually, I think I've found a pattern. Three disappearances by the lake, all during a new moon. It looks a lot like a werewolf. I'm glad you're with us; you'll help us figure this all out."
