Bolded is mine. This is exactly why Casey would have involved her father in trying to cover up what she did, thus potentially incriminating him, instead of her brother. I think Casey really believed her dad would, for the sake of maybe for the first time in a long time being really IMPORTANT to Casey, cover for her all the way to his grave. This is why I think he told the Grand Jury what he knows, starting at least as early as what happened on June 24 through to the present, which I believe is a lot more than we know, and which is why the state has not taken the DP off the table (nor should they.)
How many times have folks done things for those around them in order to please them and be held in their higher graces? Perhaps at the time George was happy to finally be thought of not so much as a "joke", as you put it, by his child but as someone who could actually help her, and so he did, and never told Cindy about it, but finally told the GJ.
He's probably hoping just as much as Casey that she'll somehow get some good plea deal, and that she'll take it, so he never has to fess up to Cindy re: what he told that Grand Jury about their precious Casey. This is why I think he has, after that GJ day, gone on with the "Caylee is alive" charade - if a plea happens, and he never has to testify, maybe his family will never know he finally told the truth...
