I also tried to give TS some benefit of the doubt, I tried very hard but I just can't because she changed her narrative and was so vague in the beginning, "Oh he went to his friend's house, I don't do names, Al does." Um, no. That doesn't fly. He's 11, not 16 with a lot of friends guardians might not know about. She lives with him, every day. She knows who he hangs out with because HE IS 11!
I also think LE knows he got into that truck to leave and never came back. My latest theory is some sort of extreme punishment, dropping him off somewhere and telling him to make his own way home after he had thought about whatever she was punishing for. I think he may have been injured already.
