I'm confused ok.... the girl katie on part one is kathy's sister on part 2? (Hunter's mom.) Ok i thought Micah kathy's sister on part two was her sister. So is Micah katie's sister also? Because on part two i thought micah that was kathy's sister. Can someone help me figure this one out. Because at the end of part two katie kills husband and kills kathy it looks exactly like the sister. micah.
