Dean headed to his bedroom and found Sam walking down the corridor with a pillow under his arm.

"Wee Willie Winkie? Heading off to bed for now it's ten o'clock?" He asked, quoting the poem.

"I'm just returning your pillow to you," Sam said, holding it out to Dean. "I swapped it out before I left yesterday. Oh - " He reached into his back pocket. "And your toothbrush."

He handed them over to Dean, who held them as though they were radioactive, and walked away.

"I told you to stay out of my room," he called over his shoulder.
