Jade felt a sense of pride and satisfaction in herself when she saw the surprise which briefly flickered on Harry's face before it was replaced by something else. Primeval male appreciation.
Although she had felt very insulted by all he had said earlier, she had also admitted to herself that she looked a mess, and needed to clean up. Hence, she had taken her time to wash her hair and thoroughly look through her closet for something nice to wear before having her bath. After dressing up she had taken her time to apply make-up on her face, covering up all the blemish, and giving her face the color she had lacked earlier. Seeing his reaction now, she felt like gloating.
How dare he look at her like she was undesirable and ask her not to worry about him touching her? How dare he try to hurt her feminine pride? Well, seeing the way he was staring now, she felt triumphant.
