CA is a total control freak and everytime NG replays that tape showing her on the telephone in her kitchen what I see is a woman who has always been able to manipulate and successfully control the outcome of every situation, especially any situation(s) involving KC, and that IMO is what will break her, not her acceptance of the death of her grandbaby or the realization that her own daughter is responsible for her death, not even the stress of all of the press coverage or a million protester's outside of her home - she will break when she realizes that she can't control the outcome of "this one". I saw her behavior not as a grandparent who was in denial, but as someone who was baffled and completely stunned that she, CA wasn't being believed - nobody but nobody questions or challanges CA, and when you do she goes all out on a "seek & destroy" mission, as we have seen time and time again. Her break down won't be the result of overwhelming grief for the loss of that precious baby girl, it will be because she finally realizes "I can't fix this one KC" and IMHO she isn't a "fixer" out of love for her family, its all about appearance to CA, how others view her family is not only a reflection on CA, its all about CA!
