Jon, trapped in Sarah's 14 year-old body ran to the phone and started to dial Karyn. She was his only hope. Just at the other line started ring, though, he heard the front door open. Sarah was back and already racing up the stairs.
Tears in her eyes, Jon panicked. She couldn't let Sarah get the stone. Sarah had way too much power over her. She couldn't hide it, because Sarah could just demand that she give it up. So she took the only course of action -- Opening Sarah's bedroom window, Jon mustered all her reduced strength and hurled the stone as far as she could, closing her eyes so that even she couldn't be made to track it down.
The door burst open and Jon spun around.
"Alright you little bitch," Sarah sneered, "Where's the rock?!"
"It's gone," Jon pleaded.
"Gone where?"
"I threw it out the window. I couldn't find it if I wanted to."
Sarah knew that Jon wasn't lying, but it didn't make her any less angry.
"Do you have any idea," Sarah glared, "How badly I'm going to punish you for this?"
