I'm just going to warn you right off the bat that there are SPOILERS ahead, so if you don't want to know anything about the post credits scene in Captain America: The Winter Soldier then please don't read ahead.
We've been hearing that the end of this sequel is going to forever change the Marvel cinematic universe, and that the post-credits sequence will lead us into Avengers: Age of Ultron. Thanks to BrainFreeze.be we have the details on what we are going to see. In their review of the film they called it the "most serious and dark Marvel film." They also explain what happens before and after the credits roll:
"After the fall of both S.H.I.E.L.D. & HYDRA we see Baron Von Strucker (Thomas Kretschmann) in his underground lair. Loki’s scepter can be seen here, as well as 2 special prisoners: the “twins”. These are of course Quicksilver (Aaron Taylor-Johnson) and Scarlet Witch (Elizabeth Olsen). Quicksilver is bouncing from one end in his cell to another while Scarlet Witch is stacking some building blocks with her mind. Watching them, Von Strucker announces “The Age of Miracles” is upon us. And with that we learn the new name for mutants in the Marvel movieverse."
As for the post-credits scene here's what they say:
"The Winter Soldier is visiting the Captain America exhibit in the Smithsonian museum. Here he finds the information on James Buchanan “Bucky” Barnes, his real name. It appears the Winter Soldier now knows who he really was and remembers that Captain America spoke the truth about him."
So, what do you all think of how the movie ends?
