Turns out they'd been hiding all throughout SHIELD for decades, and we didn't know. Well, we knew there was a problem, we just didn't know how bad it was. I wish we'd figured it out sooner. We could have prevented so much, or done something else...
Anyway. Then Director Fury was assassinated in my apartment. Secretary Alexander Pierce summoned me to DC, and I guess he wasn't happy with my answers to his questions, because a STRIKE team came after me on my way out, and SHIELD labeled me a traitor. Natasha and I were almost killed when they bombed Camp Lehigh, but by then, we'd already learned how far back the infiltration had gone. And we learned what HYDRA really wanted to do with the three new helicarriers they'd made: pick off threats a million at a time. So we brought it all down. Helicarriers, headquarters in DC. We published SHIELD secrets so HYDRA couldn't hide anymore. We forced them into the light. I'm lucky to be here right now, to tell you the truth.
