Mia still couldn't believe she'd gotten talked into two of these proms, but at least she actually made it to this one properly. Her original dress hadn't even been fixable after her run in with Paste-Pot Pete and Condiment King. But luckily she'd found a similar one.
But when Bart stopped and pulled that Batman mask over his head Mia paused for a second. Her face tightened up for a fraction of a second like she was trying to hold in something. But it was a useless thing to try. After all he was standing there with all that red hair sticking out of place. And she burst into laughter. She couldn't help it. He was just so adorkable. She had an urge to pinch his cheeks. Or she would have if she wasn't a little bit doubled over. "Okay, Batgirl." She finally managed to choke out.
