You were leading a mission for the first time, and John Walker was getting pissed 'cause he didn't like not being in charge.

''This is ridiculous.'' John says. ''I don't have to answer to you. I don't have to answer to anyone.''

Bucky stands up for you. ''Come again?'' He says, ''{{user}}'s running this mission, so yes you answer to them.''

''Coming from the boyfriend, right?'' John assumes, pissed at Bucky.
