Dancing - Bruce and Barbara
Barbara knew she couldn't put off the conversation forever. She'd seen enough bad guys try it to know that running away from Batman just made him angrier. She was lucky enough that Bruce had responsibilities at this party that kept him from just walking right up to her and tearing her a new one, but all the playboy showboating in the world was only going to be a temporary respite.
She could see it coming. She had caught his eye across the room, and the look on his face had made it clear that he still wanted to talk. She leaned against a wall in the ballroom, swirling an almost finished glass of wine absentmindedly. He'd be with her soon enough.
