As the twin doors to the dungeon clanged shut behind the Winchesters, Crowley frowned.
"Wait…" he said slowly, realising that they were going to leave him there for an undisclosed—possibly very long— amount of time. "Can't you leave me something, at least?" he called to the fading footsteps. "Pack of cards? A sandwich? Something? Hey! Boys, listen when I'm talking to you! Hey! Hello?"
As the door to the library slammed shut, Crowley slouched back in the chair as best as he could with the demon-proof shackles restraining him.
"Hello?" He called meekly. "Moose? Squirrel? Could somebody let me out of here? Kevin? Please." He paused. "Abaddon?"
He let out a resigned growl. "Bollocks."
