well the story behind the winter soldier is, pretty much american patriot hero sidekick, thought dead, reprogrammed by russia to do wet work behind the scenes, with no memory. Think weaponized Manchurian candidate.
plus with that peter connection now, which has a mole story line i think that is where people are making the connection. Plus just think of how he short circuited last night. These people need the constant flow of instruction to function, meat robots.
