Isaiah saw the three people entering the room where that older woman had been killed by Melanie. He may have adopted her, but he wasn't going to call her his daughter. Not that monstrosity. He turned his head to warn them. The girl saw him turn his head and screamed. The other two rushed her out. Why was everyone always afraid of him? He was only trying to warn them about Melanie. Why wouldn't they listen? He heard Melanie laughing. She always laughed after a kill and when anyone ignored him. She was truly evil.
