The challenge word is copy and I got carried away so it's a double (200 word) drabble. The boys have some explaining to do!
"So, I can't even...trust you to accurately copy a...simple warding sigil now, huh?"
Sam gasped breathlessly as he lunged across the bed but even with his long reach he missed his fleet-of-foot quarry by centimeters.
"Just shut...up and grab...the damn demon, Sam. It's gonna t...trash the entire room."
Dean crashed noisily into the bedside table knocking the lamp to the floor as the animale demon's sharp hoof tore a deep groove into his shin.
"Oww!" The elder Winchester sank to the floor gripping his leg as the motel clerk began hammering at the door.
"What's going on in there? Sir? Either open the door now or I'm using the pass key."
Dean looked round at the scene of carnage. This was going to be difficult to explain.
The leg on the bed had broken the first time Sam had thrown himself, long legs tangled in the sheet, at the creature. Most of the furniture was trashed. It wouldn't have been so bad perhaps if the demon hadn't found them as they slept but Dean really wondered how they would explain the considerable damage, their state of undress and the very agitated, baby goat!
Silly. I know!
