The appearance of the woman and whatever was floating behind her startled Vanya, especially when she asked her a question. "Uh, no, I haven't," she said. She didn't even know what this building was. "Where am I? Who are you?" Maybe she should have tried to play it cool to obtain information without admitting how clueless she was, but she didn't have the patience for that.
Vanya eyed the other woman who was nearly as slight as she was and yet had the most unusual appearance she had ever seen.
