So right now I am feeling pulled in two directions, but perhaps they are possible to merge.
1. The TV; we now know that HD just started sleeping in her own room the week before she went missing. I can't help but think there is a connection there. Perhaps SA was finally able to sneak into a secluded place at night with her. And maybe she threatened to tell someone, especially if they were now engaged.
2. The 7 yr old boy:
This is still bothering me. Cz tried to steer us in this direction. I resisted because I saw no motive for CD's girlfriend. But the father of the 7 yr old is a whole different question. Was he angry at Clint? Could he have been at the house that day to pick up his son? Did he get the chance to take off with HD?
Did SA and the boys Dad know each other and help each other out?
