Yeah. A bunch of bodies wearing Hydra uniforms in front of a museum was not subtle. It wouldn't have been subtle, even by Steve's standard (he was only vaguely familiar with the definition of the word, and only in theory), even if Steve hadn't literally been able to smell Bucky.

He wasn't in disguise and he wasn't in uniform. He was wearing jeans and a jacket, and he didn't have the first problem entering what Bucky had already broken into. It was dim, eerily lit because of the exhibit spotlights, but it was good enough for his purposes.

"What are you," he asked what looked like empty air, "a cat?"

Dropping prey on the doorstep?
