Derek watched Stiles until the boy was safely in the bathroom. He quietly stepped over to it and locked the door from the outside, making sure Stiles couldn't run anywhere. He slipped the key for the bathroom into his pocket and went downstairs to make Stiles a sandwich and cut up some strawberries for him to him to eat. He didn't want his pet malnourished.

But when Derek came back up and Stiles was still in the water, he sighed, checking his watch. 13 minutes. He paused for a moment, contemplating what Stiles' punishment would be, before setting the plate on top of the cage and unlocking the bathroom door. He wasn't going to give Stiles a warning. He opened the shower door and reached for the collar, dragging Stiles naked and wet out of the shower and onto the floor.

"What did I say to you before you went in here," he snarls at the boy.
