General Huo is just trying to conveniently shift blame rather than recognize the wrong itself. You know he doesn't feel an ounce of guilt, he just blames her because he got in trouble trying to deal with the problem so as to get her attention. Perfect narcissist behavior.
Our girl did an excellent job of predicting how her enemies would try to challenge her and now she gets a title, relief funds for the victims, and full say on her marriage. You go girl!
That said, I worry Huo is going to get cleared one way or another and he's going to demand Nan Yun as his reward.
