Excellent suggestions and inquiries. Tis would make sense, though I believe Misty was home because she had no ride. But, if Misty did have her mom watch the kids, then this turns the case upside down again. I don't see Misty leaving the kids alone.
This would also explain the not everyone knowing anything going on with each other. If LC was watching the kids, Hank sr.and jr. knew it.
Also they all would have been there with Ron's kids when he called checking to see if Misty was there. By the way, ron's lawyer confirmed tonight that ron never asked hank or anyone to go to his home and check on misty and the kids. Keep these good thoughts coming, enjoyed reading your post.
