I think Jose Baez might have taken some wise advice from his new attorney and decided to try to plea. He might say now, well, given her increasingly eratic behavior that we as counsel have come to see in her, there does seem to be mental illness, and her family is willing to come forward now to back that up. Remember, IIRC, GA said, "We noticed a real change in her behavior after the baby was born." This could help them lay the foundation for it. It wouldn't be a strech for Baez to get experts to refute the state's recent findings of sanity, or Casey's ongoing claims of sanity.
Frankly, I think there might be something to it all. I thought that there was some kind of black out episodes when her brother asked her in jail, "was this like the time before that you told me about," and she answered, "yes." I just got a feeling it was something like that, and now she can use Lee to back it up, to say she has lapses or blackouts or something like that. They can also point to the friend who claimed that Casey told her she thought she was crazy and would like to check herself in. Anyway, goodnight, friend.
