"Your name. I'd like to know your name." She doesn't bother with 'please', because Setsuna has given her no reason to believe that he's warranted niceties.

She even chills her fidgeting down to an occasional roll of her wrist, so as not to look intimidated. She's aware of what she's capable of doing to a person, and as such has no need to be frightened of a creepy kid unless he gives her a reason. Even when caged.
