[Captain America faces the Winter Soldier aboard the third Project Insight Helicarrier]

You know me.

[Attacks him]

No, I don't!

Bucky, you’ve known me your whole life. [Receives fresh blow from Bucky without fighting back] Your name is James Buchanan Barnes.

[Hits him again]

SHUT UP!

[Takes off his mask and drops his shield out of the Helicarrier]

I’m not gonna fight you. You’re my friend.

[Pushes him to the ground]

You’re my mission! [Mercilessly punches him repeatedly across the face] YOU'RE... MY... MISSION!

Then finish it. [The Winter Soldier gets ready to punch him again, holding his fist up] 'Cause I’m with you to the end of the line. [The Winter Soldier looks stunned and hesitates]
