He burst out laughing at Batman's insistence that he didn't take bets with villains. "Well, you know what they say right?" He managed to squeeze it out between his laughter. "Don't take the Devil's bargain and you'll find his boot up your ass!" He was shouting, there was no way around it with that damned door. But that was beside the point. With Harley out there Chanah might actually be able to do something.
Wiggling his arms, he heard Harley mention a shield, and his face grew serious for a moment. He had to get out of this damned jacket at the very least. Thankfully, with all of his banging around had loosened the straps to the point where he might just be able to... There! An arm shot free and he broke down into laughter. "Harley, do what you have to, but if you knock him out you wait till I'm out there to pull off that damn cowl!" He struggled for a moment and then suddenly the other arm popped free and he was standing in the middle of his cell with a suit coat that had sleeves twice as long as his arms dangling about him.
As free as he could be at the moment, he contented himself with skipping about singing to himself. "Jingle bells, BATMAN SMELLS! JASON TODD IS DEAD! I'm locked without a nut and Harley'll save the day hey!" He giggled and thought it to be quite the lyrical masterpiece. Besides, Bats never did get over that whelp of a Robin.
