Re: Steve & Yelena
Yelena had only half considered the possibility of Captain America agreeing to fight her. She had wondered if he had some weird moral honour about fighting women or something, so when he agreed she looked pleasantly surprised. "I'm younger so I'm technically faster." Which wasn't entirely true and there was humour evident in her eyes. The truth was that between her and Natasha, it was usually a draw, but Natasha had an edge on things like space travel.
"At least this time I asked permission. I accidentally tried to kill Barton when I first showed up."
