Without hesitation, Bucky takes off after him, tempering his speed to match so he can keep an eye on the other man. There's no point in learning these skills if he doesn't practice them the way he'd want to use them in the real world. This isn't just about his own survival.

His form is a little rough on the snow, but it doesn't slow him down. He can hear the quiet echoes starting to grow behind them and he thinks this survival is just like any other. It's about staying alert and avoiding the danger entirely.

Bucky's only ever been good at the first half of that.

He glances back quickly, but the snow is still gaining momentum and it's still unpredictable where it will go.
