Dean stood frozen in front of the door. He'd heard something squeaking inside.
"This one's clear."
"What? How can you possibly…" Sam frowned as he stepped forward, reaching for the doorknob.
"There's nothing in there, Sammy. Don't open it." There was an edge of panic in Dean's voice.
Sam snickered. "Oh, that's right. I've got this one. Rats don't bother me."
Sam gently pushed Dean back and opened the door, then stepped inside. Rats coated the floor and ran over the furniture, their eyes shining in the dark.
"You're right. Room's clear!" Sam shouted to Dean as he passed, flying.
