Bucky always calls Steve 'Steve' so when bucky actually says ['Steven'] that's when Steve knows he's literally screwed. A cold shiver runs down his back. HE KNOWS.
Natasha: "at least you didn't die from jumping out of that quinjet without your parachute again"
Bucky: looking at steve "Steven Rogers..."
Steve: instantly shivering from fear. As bucky just stares daggers into his soul.
