Jesse says that the claims of molestation attempts were all he needed to hear, that he wanted nothing to do with Lee. So, had he ever had anything to do with him previously or even met Lee yet? Maybe Casey didn't want Jesse to hear about the check stolen from Lee or other things about herself. Hopefully, if the jury hears this they will also force Jesse to tell what brought this all up, that she wanted him to move in with her before marriage and also how she lied about paternity and not having a job while his parents babysat. Oh, and how she broke up because he loved Caylee more than her, and was also out partying.
