Was that an invitation to send in more headcanons? :3 So! Sam is born with “On your left!” over his heart, but the thing is– it looks kind of weird. Like if a typewriter stuttered, giving the words a drop shadow. It’s definitely unusual, but Sam has seen weirder (there are more than a few people these days getting marks in languages no one can *recognize*, let alone read) and everyone just chalks it up to his future soulmate having a stutter and thinks no more of it. (1/?)

suzukiblu:

That is, not until the day Captain Fucking America runs past and definitely does NOT stutter “On your left”. Nor does he stutter the next 2+ times (now you’re just rubbing it in, man!). Maybe that’s the reason why Sam’s got his worlds doubled up? Man like Rogers, he really wants to make his mark, Sam guesses. Flash forward past CATWS, flash forward to the conclusion of The Great Bucky Hunt, and they’re bringing their boy home now– well, /Steve’s/ boy, Sam has to keep reminding himself. (2/?)

The thing is tho, even if Bucky doesn’t talk much (read: at all), the 3 of them have still managed to build up a nice rapport. They took on those last Hydra bases together, working well as a unit even if it was only Steve & Sam providing the background chatter. They don’t push Bucky to talk if he doesn’t want to (he can clearly still vocalize– the nightmares prove that well enough), they can work well enough off of facial cues and military hand signals. He’ll talk when he’s ready. (3/?)

But for now their Hydra-hunting days are paused– they’ve done everything they can at the moment, checked off every one of Bucky’s stops on his revenge tour. Now it’s time to go home and recuperate before the next thing (there’s always a Next Thing). Steve and Sam immediately jump back into the habit of a morning jog, Bucky trailing behind them uncertainly (a predictable path? out in the open? with all these people?). Bucky sticks to Sam like he’s there for protection detail, not exercise. (4/?)

Steve ofc is a little shit doing his normal routine of running past them with cheerful “On your lefts!” every time. After a while of this, Sam turns a sly eye to Bucky “So… think you can match him?” Bucky nods hesitantly. “Think you can… beat him?” Bucky nods decisively. The next time Steve laps them, Bucky is in pursuit. Once Steve realizes he’s got a shadow, he laughs and speeds up EVEN MORE. (5/?)

Maybe Sam miscalculated. In no time at all, Steve (with Bucky on his heels) is coming up behind Sam again, “On your left” already on the tip of his tongue, Sam can tell. But! Then Bucky puts on a burst of speed and manages to make it to Sam first. Surprising everyone present, he calls out “On your left!” triumphantly. And– and it clicks, then, for Sam, because then there’s Steve, saying the damn thing one beat behind, two voices in stereo just slightly off. That’s what it meant all along. (6/6)

This one I’m just posting without comment, WHAT CAN I POSSIBLY SAY TO IMPROVE THIS ONE?? WHAT. WHAT COULD I POSSIBLY SAY.
