I would really love to know what Cindy's mindset is at the moment. Realistically, there are only a couple scenarios that exist:
1. Casey killed Caylee and covered it up.
2. Caylee died accidentally and Casey covered it up.
3. Caylee died accidentally and Casey and George covered it up.
4. Zanny the Nanny really does exist and Cindy is determined to find her so she can get the real story.
I can't think of any other options. One would assume that if Cindy believed Casey killed Caylee on purpose, she wouldn't want anything to do with her.
One would also assume that if Cindy felt George was involved, she would have personally killed him by now for dragging this whole thing out for so long and potentially sending Casey to death row.
That leaves option 2. Cindy really believes it was an accident that snowballed. Even if that truly happened, how can she welcome back a daughter that made up horrible stories about her own father; stories that were told in front of the entire world? Stories that will likely make it impossible for the man to ever work again or ever have true friends anymore because there is the tiniest little doubt that might linger. Cindy can't possibly believe the sex abuse allegations or she wouldn't still be with George. Yet, she is willing to be in her daughter's life after everything that has taken place??
