With a lot of us thinking that the defense is going to use 'prior bad acts' so to speak, to blame George and/or Cindy for KC's behavior, I went back and found the video where she tells them "I haven't said anything, don't worry". Watch the first 90 seconds of this visit and see if you agree with my thoughts.

Watch Cindy's expression when KC says she has been talking to one of the doctors. Cindy then says "we forgive anything that you've said". KC replies with 'I haven't said anything, don't worry' in a very light and breezy manner. There are one or two awkward pauses during this exchange. Knowing that JB spent his own money to have the jail visits transcribed, I am willing to bet that this video and the transcript are going to be one of the first things the defense enters as evidence when/if they start their case in chief.
