"See!" Barbara held out a hand in Peter's direction as if his assessment of capes made her right, and well as far as she was concerned it did. "You just never learned to appreciate them for all they can do." She said primly. "I wouldn't know about that, Batgirl has always been enough for me."
Barbara grinned wide when Dick confessed that his version of Robin hadn't worn pants, "Please tell me you had those little hot pants that I've seen Tim in." She said smiling hugely. "You had pants, sure they were skin tight, but pants none the less where I'm from." She teased him, but you know Dick was always trying to show off his ass even when they had been teens together. So she'd never been too shocked by his costumes.
Maybe this was a little weird, Dick and his small boyfriend, but Barbara was enjoying herself and she liked being able to just laugh and joke and tease for a little while, to stop stressing out quite so much. It was still there of course, in the back of her mind, the knowledge that there were things she was missing back home but she was here right now and she wanted to focus on this.
