From chapter 40 of The Long Road Begins at Home by Owlet
"You were sad," Barnes says.
"Well, yeah, I guess so."
He guesses so.
"Rogers."
"What? Okay! I guess I was pretty off-kilter at first."
AT FIRST
Mission. How the hell did we get so attached to this dumbass.
ROGERS
"I don't know what I'd do without you, Buck," the briefing supplies in child-Rogers voice.
Yeah, okay, you two. I know, I'm not planning on going anywhere.
In the story, Bucky just recently went on a mission to protect Pepper Potts at a function, cause he’s the scariest guy she knows. In order to not be recognized by any possible HYDRA agents there, Bucky went in disguise, which involved getting a haircut and a shave.
Tony was not happy about Terminator being on Pepper-protection duty, so he told the hairstylist to give him Steve Roger’s haircut and his (Tony’s) goatee. XD
Poor Bucky looked like a TOOL. (Which worked perfectly, but still.) So his hair hasn’t grown back out yet, but he’s at least going for the scruffy look today.
He’s become friends with Pepper, Natasha and Maria Hill and the three of them bought him a closet full of clothes when they found out he only had TWO t-shirts and as many pants. (Steve thought he had multiples of the same thing, and that’s why he wore the same outfits all the time) They also got him bright green sneakers, because they’re “fun”. He wears them all the time because fun was not a hallmark of the Winter Soldier, but he’d like it to be part of Barnes.
