i think Kathryn was never a good girl she was smoking weed, even said she did other questionable things in college. i honestly think she calmed down in her relationship with Luke. But is now getting back to her old self because of Luke's actions, the only thing holding her back is that she thinks luke isn't open to her wild self, but she slowly realizes that he is.
but it's all just my opinion![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
