BBM: This is MOHO!
I brought this over because it got me to thinking. HD told grandma this on Christmas and grandma didn't tell BD or CD right then, she never would have had the chance. HD went missing just 2 days later. I am NOT saying it was ok not to nip it in the butt right then. Since HD was staying with CD, maybe Grandma felt she would be safe until she could talk to BD in the next few days. Little did she know, that Christmas was likely her one and only chance to alert HD's parents. I believe she never should have left grandma's until it was looked into.
