Spoilers for 'Captain America 2' ahead!

If you saw 'Captain America 2' in theaters this weekend (and, judging by the box-office, you probably did), you likely had a lot of questions afterward. Like, what's going to happen to Marvel's 'Agents of S.H.I.E.L.D.' now? And, who are Scarlet Witch and Quicksilver. We've focused on those, and now it's time to focus on the other 'Captain America 2' post-credits scene.

We spoke to The Winter Soldier himself, Sebastian Stan before the film opened about that scene and what it means for the future of the character and the franchise. Stan says he knew it was coming. "My job is to know! I knew everything I needed to know before we even shot the first movie. It all makes sense that something like that was implemented."

The "something like that" was The Winter Soldier slowly regaining his memory and remembering who he is: Bucky Barnes. That second post-credits scene shows Barnes arriving at the Captain America exhibit at the Smithsonian and looking at a memorial of himself. Stan says that scene was "part of the original script...everything was shot at the same time." (With the exception, obviously, of the Quicksilver and Scarlet Witch scene, which was later written and directed by Joss Whedon.)

So, what happens next for Winter Soldier?

In the comics, Bucky finds an ally in Nick Fury, another former S.H.I.E.L.D. agent who has gone underground. Fury helps rebuild his bionic arm and he works alongside them until Captain America is killed by Crossbones and a brainwashed Agent 13. Bucky then becomes the new Captain America at the behest of the dying Steve Rogers. It's not 100% that's how 'Captain America 3' will go down, but if they need to reboot the franchise with a new actor, that's certainly one way to do it.

We asked Stan about those possibilities and while he seemed excited, he was non-committal. "There haven't been any conversations about that. You'd be imagining where it would go, but we need to get this movie out first.
