One day, Harry had the strange urge to try something...

"Morstorquem!" He cast, and looked down in shock at the collar and remote that appeared. "What does this do?" Harry wondered aloud, and inspected the remote in his hand. It was black and had two buttons and a dial on it. One button said 'pain' in white letters, and one said 'heat'. One end of the dial was green and said 'mild' and the other end was red and said 'severe', slowly fading from the green to a yellow to the red. "Shit." Harry swore and tried to resist the urge to put it on. After all, this was a collar, for Merlin's sake, and Harry Potter did not wear collars. This shouldn't be this hard. Harry had gone his whole life without wearing one, and he wasn't about to begin now. Harry's traitorous hand started to move upwards, towards his neck, where the collar would look so good on him- No! Harry. Potter. Did. Not. Wear. Collars! Did. Not! Didnotdidnotdidnotdidnotdidnot- He finished fastening the collar around his neck. Dammit. And he'd been having such a streak of not having any unwanted changes, too.
