*Spoilers if you have not seen Marvel's Ant-Man's post credits scene.
Marvel fans know not to leave their seat before the lights turn on in the theater. Ant-Man stayed to tradition and gave fans a post credits scene that featured Steve Rogers (Chris Evans), Sam Wilson (Anthony Mackie), and Bucky Barnes (Sebastian Stan). In the scene Bucky's arm is trapped in a vice and Steve and Sam have a conversation that leads into Captain America: Civil War.
Actor Sebastian Stan sat down with Buzz Feed and spoke about this scene stating,
"“I think [what Bucky was caught in was] more of a vise. But it would never happen at his own hand, by his own doing. In terms of that scene in Ant-Man, I’ve seen some of the ideas people have about it and I would just say that whatever you’re seeing on the surface, it’s not as obvious as that. There might be a whole lot more to the scene. I would say someone would probably want to put him in a vise.”"The big question now would be who put Bucky into the vise? Black Panther? Baron Zemo? We'll have to wait and see but for now share your thoughts and theories.
