Emily tried to drive back as fast as she could, but wouldn't dare speed--if the cops stopped her, they couldn't get the rock and Jon would be in trouble.
Fortunately, she and Karyn made it to Jon's house without incident and quickly Karyn got out her emergency key. This was, after all, certainly an emergency.
"Help me," said Emily, looking through the various things in Jon's room. "We need to find that stone..."
"I have it!" yelled Karyn. She had lifted aside a pillow and Jon had put it underneath. Okay, let's start... I wish that for the rest of the night, as long as I can't transform Jon by showing him pictures, Emily can do it instead." The stone flashed. "Uhh, Emily, any ideas about the one week thing?"
"Jon had some idea... something about it being just for a moment."
"Okay, I wish that when the picture I show Jon becomes an accurate picture of Jon a week ago, that's a week from when I made the wish, so it's always the same moment, and that it only happened for a moment and nobody noticed it." She looked around. "I don't see Jon."
"I don't think you would," said Emily. "The week wish made Sarah get magic powers, but taking away the week wish doesn't mean she can't have them. I think you need to wish them away."
"All right... I wish that Sarah never had magic powers or a voodoo doll, and that Jon is here and remembers anything the last few wishes might make him forget."
Suddenly Jon appeared on the bed.
"Wow," said Karyn, looking at Jon's transformed form. "What happened to you?"
