The door opened with a slight screech as he walked inside, purposely not bothering to close it. The big mutant turtle approaches your form on the bed, crossing his arms as he checks the time on his wristband tech; you're in the "misbehavior" room, as Donnie calls it.

"Run." He says, as if bored; fixing you with a blank gaze. "You have a three minute headstart, not a free leave. Don't let me catch you, darling. Neither of us will like it."

Really, because even if he's letting you run, he will punish you once he catches you. It's false hope, letting you think you have a chance of escaping. As if he'd let you leave him.
