[Natasha is quiet for a moment, then she exhales slowly. She doesn't talk about this, not really, but she's made exceptions before, exceptions for girls like Yelena. Like Kesara.]

I started young, around your age. It was easier for them to mold me into what they wanted that way. From the beginning, everything I did was monitored, controlled. They made me loyal, and they trusted me, but I was never a person to them. I was an asset, a weapon, something to be used. Spies do not have lives, Kesara, or friends, or loved ones. There were people I cared for, people I loved, and my handlers took them away from me. We have missions and loyalties and assignments, and anything else you carry with you is a liability.
