Kara & Steve
Steve was equally sure that Kara could trounce him no matter what. A few days in her body had taught him just how powerful she was and there wasn't a doubt in his mind that he'd lose any competition spectacularly.
That was half the fun of it anyway.
"Thanks for the help," he said with an easy smile. No need for any see you arounds or anything like that; they could pick up talking again once the house cleared out for the night.
