they never let him hurt anyone - steve makes absolutely sure of that - and over time, it happens less and less often, but bucky never really stops being afraid of what he could do if he lost control.
he’s sick for days - steve reassures him that’s to be expected, and he decides to believe him, even though he knows perfectly well that steve doesn’t know shit about medicine. he stays at steve’s apartment - steve had been adamant that he’d be most comfortable in familiar company rather than in a hospital, as long as it was safe - but a doctor comes by regularly to check on him and steve and sam are very careful to follow all of her instructions to the letter. bucky knows perfectly well they’ve got her on speed dial and won’t hesitate to call her, so he’s on his best behavior. like he’d be on anything else when he feels this terrible.
the progression of time isn’t entirely clear to him, but he does know that steve is like a damn guard dog; just about every time he wakes up, steve is at his elbow, sometimes dozing, but more often asking him if he wants some water, or some crackers, at least, c’mon, buck, you’ve gotta eat something.
everything is a bit of a blur, but sometimes he falls asleep to a cool cloth on his forehead and someone’s hand stroking his hair, and he remembers that with unusual clarity. he thinks maybe he did that for someone else, once, but he can’t quite remember.
