[Hey, he heard her laugh when she was mocking his failure of a pranking suit. This is...not that same sort of laughter. She's crazy. Possibly crazier than he gets when he's Joker; then he's nothing but a wild animal, but she's still got some shred of reason, possibly.

He's tempted to show her just what the belt can do but frankly, he doesn't know how survivable this encounter is. He'd be starting flat-footed and has no real weapons of his own. Still warily holding the card, he's going to be inching back towards the door to the house, glaring as he does so. The belt's staying put.

He slips inside. You can probably hear the click of the door locking behind him. If you listen closely, you can possibly hear a strange electronic voice saying "Change." He's transformed in there, just in case.]
