Vision & Tony
Kaylee was at the wiggly age that made dressing a slightly more vigorous activity that it had previously been, and made the choices for her costume slightly more difficult. Until he had gleefully come up with an idea that would probably make Bruce kill him.
A stretchy black onesie for her, a stuffed black tail pinned in place, a pair of black cat ears, a chunky necklace of fake sparkles for her to play with, and she made a more than respectable Catwoman. For himself, it was all black, a cape that had an appearance of stiff wings, and a dramatic mask with sharply pointed ears - Bruce was seriously going to kill him for going as a Batman that deliberately looked nothing like the actual Batsuit, with the argument that Batman was a rogue as far as the law was concerned.
Kaylee might be at the wiggly stage, but she wasn't quite at the "escape from confines" stage yet; that was all on him. He was just taking her back upstairs after a circuit to deliberately show off to some of the social set he always saw at these things, just in time to witness Vision and Eira and the shocked audience. "Y'know, I always like seeing about two years into my future," he remarked as he wandered up to Vision's side, flicking the cape out of Kaylee's curious fingers. "It makes me so much more grateful for her not yet having the walking thing quite down." It would all speed up after that.
