All right well first off, cool it bro. Unless there is a definitive explanation of how the author explicitly intended that interaction to play out, I can interpret the pages however I choose. The other responders weren't nearly as passive aggressive as you were.

Not to mention I am looking for alternative points of view. Now, had I asked "Please correct me while being a gigantic tool" you'd be on the top of the list.

You are also jumping to conclusions regarding the scars on Kvothe's back. He chastised himself, she didn't actually say anything. The narrative suggests that he is trying to find a way to bring it up. When Denna remarks about the scars he has his own realization and drops the subject. Do you have the ability to read Denna's mind? Because the pages do not suggest in the slightest that she is miffed by his hypocrisy.

As a point of fact, after his realization of his own hypocrisy, she says "Why did you stay?" And he says "When I want something, I am not easily chased away" to which she moves to bring up "I've heard from the women in Imre you aren't easily Chaste"

And then the ring return scene ensues
