"Well," Zoe said. "Then you'll have to watch your sister die. I don't need this body. I can take over anyone else, as I please." Zoe, then, dropped to her knees, obviously in great pain.
Jon couldn't believe this was happening. What was he going to do? The stone was very powerful. He couldn't just hand it over to them.
"I know where it is," Karyn said.
Jon was shocked. "Karyn, how could you tell ..." Whe he looked around at her, he stopped talking. She was wearing the same latex body suit that his mom and Zoe were wearing. She had been taken over. Zoe's torment was obviously a diversion so they could take over Karyn without Jon knowing.
She left the room and went to Jon's bedroom. They followed her there. She was looking for something under Jon's bed. She stood up when she had found it. It was the box that held the stone.
She opened the box.
