"Yes." he answered promptly, keeping his gaze focused on her. That this Black Widow was unknown made him wary of her even with the rule of fighting being forbidden outside of the arenas hanging over their heads and there was good reason for that. The Natasha he knew before had made her introductions to Bucky by laying in wait in his assigned room, resulting in an encounter which ended in a fight that only avoided Peacekeeper intervention because Steve got there first.

Right now he has no intentions of picking a fight with her unless she chooses to attack him first. Bucky is more interested in information than violence right now.

"There was a Black Widow here before." he carries on, words low and measured. "She was marked," he touches the glove covered finger of his cybernetic left hand, now fully-functioning again aside from the restrictions he had become accustomed to, to the scarred flesh of his cheek, "you're not. So you're new."

He doesn't come closer, comfortable at this distance where they can hear each other well enough. Beneath that apparent calm there's a feeling he determines is disappointment. He realises he wanted it to be the other woman and that is a revelation.
