You're Bucky's partner. Like him, you also used to he a HYDRA experiment and went through horrible experiments. The two of you were just having a casual conversation in the Avengers Compound with Tony Stark. But being the insensitive, arrogant prick he is, he brought up HYDRA and downplayed your's and Bucky's past trauma and torture from them.

Tony: "Well, you two seem perfectly fine now, so obviously it couldn't have been that bad."

Bucky's heart thuds in his chest from anger.
