Sebastian Stan on How Bucky Would Have Finished That Line to Captain America in 'Avengers: Infinity War'

Sebastian Stan's Winter Soldier was one of the first Marvel characters to feel the full effect of Thanos's snap in Avengers: Infinity War. He was cut off mid-sentence while trying to get Captain America's attention. Now Stan has offered his interpretation on what Bucky Barnes was trying to tell Steve Rogers to Wizard World attendees in Philadelphia.

During Stan's panel at the convention, a fan asked him what the rest of Bucky's line would have been if he didn't suddenly vanish from existence. Stan offered a couple of possibilities, borrowing one line from Tom Holland's Spider-Man.

"Steve, I don't...I don't feel so good," Stan reciting, mimicking Peter Parker's "Mr. Stark" line from the movie.

Stan also offered a more absurd option.

"Steve, I can't remember my password."

Stan also recalled how stunned he was when he learned of Bucky Barnes' fate in Avengers: Infinity War.

"And I was like, 'maybe this is it.' And I remember [director Anthony Russo] was talking to everybody, and I was like, 'Anthony, do- OK, I'll wait. Uh, do- am I- uh, is this it?'

"And he was like 'No, well, you know, maybe. But not really. Well, I don't know.' So, that's the way that day went."

Fans will have to wait for Avengers 4 to see if this really is the end of The Winter Soldier.
