Re: Bruce & Yelena
"And here I thought I was unable to be covert here what with Natasha and all." She paused. "Maybe I shouldn't have scared a bunch of people when I first arrived too - probably that was worse." Probably. She would definitely give Valentina a talking to the next time she saw her.
"My name is Yelena. Natasha's little sister." She even held out her hand. See? She could people sometimes. It might be that Yelena wanted to see if Bruce Banner had any strength in him, but it was still peopling.
