ITA with everything you said, Janine. Especially about George fearing Casey. I think he knew very well what his daughter was capable of, from his comment about hoping the smell wasn't his daughter and/or granddaughter, to his telling one of the detectives (was it YM or the other guy?) that if something has happened to his granddaughter, he has lost his daughter. To me, that was the closest someone can get to saying if Caylee is hurt KC did it without coming out and saying it.
I am hoping at some point CA looked around at her life and said, what am I doing? KC has tormented me and my family, terrorized our home, and stolen and lied, and all this was before Caylee. They stood by her even as she lied and tricked them, teasing them with "clues" about Caylee, led them on and then finally distanced herself from them completely all the while they remained available to her. At what point do you ask yourself - what are we fighting for?
