Aria doesn't know how to react. With Prince's assurance about receiving the cookies and eating them made her feel alive that doesn't have a sense at all. Aria has known that Prince wanted to avoid her after the kiss, and that their interactions wouldn't be as cold as it may seem. She doesn't have enough time to consider her next actions were after that moment.
Now that their wall has broken off once again, Aria must have the time to take care of the things she needed to do the most. Her smile gotten a bit off and Prince was munching off the chocolate chips for a while.
Aria sighed, saying, "If I would do that favor, would you do the same thing to me?"
She rubbed her hands, letting the crumbs fall off from her fingers, and anticipated Prince's words more than the favor he had asked for. Aria waited, letting Prince have a moment to think of his honest answer.
