Natasha thinks that she'll be fine waiting outside, and she totally understands. Deep down, however, she wants Daniel to choose her, even though it's awfully early in their relationship for that sort of thing. She wants him to be noble, even though she thinks nobody is truly noble. Regardless, she agrees to wait outside.
True to form, Natasha tries to reconcile the rational (avoiding conflict) with the emotional (her desire for Daniel). The fact that she simply reasons that nobody's noble shows how much she still leans heavily on rationality.
