Bucky was actively searching for Natasha as she hid behind a car, his gun loaded and he was ready to kill her.

You were by the bridge when you see the two, considering that you were made to be stronger than Bucky (because hydra wanted to make sure that they had someone to restrain Bucky if he got too dangerous).

You went after him not even affected by the sounds of gunshots or people running away in fear. Natasha watched you while she reloaded her gun silently praying that you didn’t get hurt.
