This is the scene people don’t pay attention to in the first movie. This scene gets me. First off because Steve even looks startled at the end, and it’s a sort of concerned startled. The way that Hydra soldier snaps back implies this was a head shot. You see Steve take out people, but never with a cold efficiency like this. Steve is grateful, but his expression is sort bothered at the end. Like he can’t really fault what Bucky just did, but DAMN. Second is the look on Bucky’s face. He’s in a place where he can shoot a man in the head and his facial expression doesn’t even change. If anything he looks almost satisfied at the efficiency of what he just did. If you want to see Bucky look like the Winter Soldier in the first movie, this is the moment. This is the only time they imply Bucky was a sniper and everything that entails, the patience and sheer detachedness it takes to be that.
This scene surprised me even when I was watching the first movie back when it came out, because DAMN Marvel, you just had a major character shoot someone in the head and not blink. Because Bucky’s not Steve. Bucky can go to a place Steve can’t and when people use that in him to make him a weapon that’s terrifying. But when he uses that to protect people it’s incredibly efficient.
