The Winter Soldier doesn’t speak more than he needs to.
While his programming is still strong enough that his face doesn’t tell a thing, the way he talks is a total tell-tale.
In a line just preceding this, he is efficiently curt-Она моя, найди его. ‘She’s mine,find him.’ Only the basics one needs to understand the order; it’s completely emotionless and sparse.
It is interesting, compared to the downright chilling calmness with which he carries himself during battle. Everyone else might be scurrying and running, but he never rushes. He isn’t non-verbose because he’s pressed for time, he is curt because he was designed to be brutally efficient in every aspect, including talking.
So why on Earth, when facing his mission and having him on gunpoint, he says what is probably his longest line in the whole film?
Why would he even bother to speak? Many other objectives have talked to him, probably pleaded,promised,accused. Why should he care what the man on the bridge is saying, when he is supposed to be dead in a moment?
Perhaps, “Who is Bucky?" could be acceptable, given it’s information his superiors might find useful. He doesn’t know or care, it’s just another sentence he’ll add when he is told "Mission report,now”.
But “Who the hell is Bucky?" is just unnatural for the Winter Soldier. A completely inefficient curse thrown in. Inefficient, that is, for a less-than-talkative assassin.
Cursing relieves emotion, though. We curse when we’re scared,angry,hurt,frustrated,elated,amazed. When there is an overpowering emotion we need to express in every way possible.
That little ‘the hell' is the human inside the weapon. What could be strong enough to overpower the sterile straightforward programming, though?
For the first time in 70 years someone gives him a name. There is recognition and emotion all over his mission’s face. Emotion that isn’t horror, but disbelief,relief,hope.
Someone names him and goes beyond that-shows him he has much more to tell.
It fucks him up. The name stirs up shards of memories, not enough for them to surface, but enough to disbalance the Soldier’s inner order. For the first time during a mission something is interrupting his flow of action and it’s something he can’t overcome.
In that moment he is frustrated, both at the turmoil the target caused in him and the uprising need to know more. His programming doesn’t function well when there are emotions present. He knows he has to shut them down in order to finish his business, but for the first time, he doesn’t want to.
It all results in the most sincere and emotional thing he has ever said since he became the Winter Soldier.
"Who the hell is Bucky?...Is this me?”
