So obviously the clothes Bucky’s wearing in Civil War definitely aren’t his Winter Soldier “uniform” and I doubt he waited till he got to Romania to buy those, which means that shortly after the end of Winter Soldier, unlessHYDRA somehow kept civilian clothes in his size on hand and he knew where they were (ya know, the boring option), either:
1) some poor body builder got mugged in an alley by the actual Winter Soldier
2) the world’s most wanted assassin walked into a clothing store in his full leather getup, a wad of “stolen” HYDRA cash clutched in his metal hand, and bought himself a pair of jeans and a couple of t-shirts
Some of us… Well, most of us… we’ve all done terrible things on behalf of the Rebellion. Spies, saboteurs, assassins. Everything I did, I did for the Rebellion. And every time I walked away from something I wanted to forget, I told myself it was for a cause that I believed in. A cause that was worth it. Without that, we’re lost. Everything we’ve done would have been for nothing… I couldn’t face myself if I gave up now. None of us could.
