M'gann didn't understand the finer points of human interactions, but she was learning. She had been enjoying her dance with Conner when the song shifted. "I love this song!" she said gleefully. She really did. She knew all the words and a bunch of the parody dance video moves from youtube. She probably shouldn't have learned them, but they were fun so she didn't care.
She'd been completely oblivious to Bart's shenanigans until she saw the look on Conner's face turn from happy to full of horror. She actually had to take a moment to make sure she didn't suddenly turn greenor white. Looking at her bare arms for a moment discreetly, she was sure she hadn't, which was good. It was then that she noticed he was asking her a question.
That's when she saw Bart and Kara and Bart's date. "I think it's happening?" She followed Conner, her arm in his as she stood beside him. "Hey, everyone."
