After choir tonight, when there is time for prayer and sharing prayer concerns, Daughter asked for prayers to help her stop lying so she wouldn't get in trouble so much. (I wasn't there, it was reported to me later.) She has acknowledged that making contact with Birth Brother wasn't a very good idea.
Daughter and I both just spoke with BB. He's an army recruiter. He's on wife number 3, who is expecting his second child. He talked a good line. The box is open, and we can't shut it again. I shared my concerns with him. He has friended me on facebook, and wants to know if the contact with Daughter is causing problems. I think the situation is about as good as it could be right now. I'm relieved.
