This was recorded a day or so after the children were removed. I saw a picture of him with the family at one of the visits shortly after this started. Of all the faces, his seemed to be the most solemn and distressed. I suspect he had no idea what would really happen. He probably didn't know his siblings would be in foster care for over a year. I suspect he is disillusioned with all of this. Time will tell.
Nobody has been in foster care for over a year. Nor do we know how long it might be.
I would suggest that Hal and Michelle, and their supporters, have lately appeared to dig in their heels in opposition to the authority of DHS and/or the courts. Continuing to claim that they are the only and highest authority in their children's' lives, and that they are Biblically mandated to chastise their children with a rod to drive out evil (not to mention some other possible issues like medical and educational neglect that may still be lurking in the background) is certainly not likely to shorten the possible time-span.
