Pretty harsh but probably closer to the truth than most claim.
If you look at some of the transcripts, Cindy had started threatening Casey with taking the plum Caylee from her. After all, the family was getting tired of Casey’s antics.
The pressure was on Cindy. She used Caylee. Not good, because that brought out the unconrtollable rage. Oh no you are not Mom, you aren’t keeping Caylee and rejecting me. In otherwards, Mom was threatening to take away that which Casey used to control everyone.
It wasn’t going to happen. Casey made sure of it. Forgot about it for 31 days and had a good time.
