Murder for hire plot -- Kaine says there was never any indication that anything major was wrong in their marriage, and certainly not anything as drastic as a MFH plot. He isn't sure now whether she might be capable of hurting a child and he now fears for his daughter.
He doesn't understand why his wife would want to have him killed, and that was a big factor in making him believe she's involved in Kyron's disappearance. His message to her now, "Fully cooperate with LE -- tell the truth."
Tony says the MFH plot moved them from being suspicious to feeling certain she was involved in Kyron's disappearance. Terri feels tremendous guilt that she was so far away when Kyron needed her protection. Feels really guilty that she had to work instead of going to the science fair, too.
Desiree says on several occasions Kyron asked to come live with them and sobbed because he wanted to stay with her. She worries that her gut feeling that things weren't right for Kyron should have been heeded. Poor thing, she is beating herself up...I'm sure any of us would.
