I am really concerned. I sincerely believe Julia has done something to/with Sky. I honestly don't think this adorable little man is still alive. I hope that Julia is being monitored closely right now. I have a feeling she is going to try to kill herself and then we may never find this child.
It sounds as if her family is not much of a support system and with her tendency to isolate herself, suicide is real concern I would think.
I too have been concerned about her mental status...and if she is on any type of professional monitoring or suicide watch. It would be tragic if she did something like that...and the truth would never come out.
