SamSteveBucky

SamSteveBucky is the polyship between Sam Wilson, Steve Rogers, and Bucky Barnes from the Marvel Cinematic Universe fandom.

Captain America: The Winter Soldier
Steve fights the Winter Soldier, and in the process takes off his mask and reveals him to be Bucky Barnes. As he's about to shoot Steve, Sam flies down and kicks him in the face.

Steve stands at the top of the abandoned dam, Sam coming up to him and tells him that Bucky will be there when they execute their plan. Steve knows. Sam tells Steve that whoever Bucky was, the guy he is now is the kind you stop, not save. Steve says that he doesn't know if he can do that, and Sam says that he might not have a choice, since he doesn't know him.

After taking down HYDRA, Sam, Steve and Natasha meet up, and Natasha gives Steve the Winter Soldier file. Sam asks if he's going after Bucky and Steve says that he doesn't have to come with. Sam says he knows, and asks when they start.

Captain America: Civil War
As the power goes out, Steve realizes that the man who framed Bucky is the one interrogating him, and he and Sam run down to the room finding all the guards unconscious. Steve enters the room and confronts the intergator. Sam walks in and a brainwashed Bucky takes a swing at him, Sam ducking just in time. Bucky is able to punch him in the gut and throw him across the room, knocking him out.

Bucky wakes up, his arm locked in a machine, with Sam watching him. Sam calls over Steve and the three start to talk. Steve believes that they're talking to Bucky without mind control, but Sam asks if that makes everything automatically okay. Bucky tells them that Zemo was looking for the other Winter Soldiers. Sam asks if they all turned out like him, and Bucky says that they were worse. Sam tells Steve that this would have been easier a week ago, and they don't know if the accords will allow Tony to help.

The three steel a car and meet up with Sharon Carter for their equipment. While Steve gets their stuff, Sam and Bucky sit in the car, Sam in front, Bucky in back. Bucky asks Sam to move his seat up, but Sam just deadpans "no". Bucky scoots to the side, Sam glancing back at him. They watch Steve kiss Sharon, and when he turns around they both nod their heads and smile, embarrassing him.
