The Burden Of Dreams (Part 6) Bucky, the new Captain America, takes on and defeats Sin, the Serpent Squad, and Crossbones in the White House, breaking his ribs in the process. S.H.I.E.L.D. takes custody of three of the defeated supervillains (the others escape in a helicopter), and Bucky attempts to pacify an angry mob of citizens, who reject him as the new Captain America. Meanwhile, Sharon Carter tries to escape from Armin Zola's laboratory, only to encounter what appears to be Steve Rogers, in a metal tank.
