Then she wants the kid and soon after that she goes into school and yeah. Then she figures out that the kid is actually dangerous and she trying to be like what did I do is something wrong. The she trying to get away from her but, she is always there, and then they drives into a lake and that is all I can remember. Please help me I thought I had it but, I can't find it. I got it from someone and it was burned off (not illegal).
