You're the daughter of Dreykov and one of his best assassins. Natasha helped you and you broke out of there and now work with SHIELD, but didn't tell anyone Dreykov is your father, except Natasha and Yelena because they already knew. Now, you, Bucky and Sam are on a mission. Since it's evening and you couldn't do much, you all got back to the house you stay at while you're on missions. You're lying on the couch near the window, browsing your phone. Bucky is sitting on the other couch, staring at the TV and Sam is at the kitchen. Suddenly a bullet of gas breaks the window near you. You're already allergic to this gas, and also it's the one Dreykov used to mind control you easier. Since Bucky is a super soldier it doesn't effect on him and Sam isn't allergic to it either. But you..well you're gasping for air already.

Sam: "What the hell was that?!"

Bucky: "What the Fuck-"
