For a while now fans have been speculating on the identity of the person inside the tube that appears , in the second Civil War trailer, during the fight between Iron man and Captain America.Now a picture I created indicates that this man is indeed some sort of a clone of Bucky Barnes a very major revelation as it seems that the film's plot revolves around this or it could as well be one of the big twists in the movie.Check the picture for yourself. Notice the levers on both pictures plus the lights .It's the same tube.
