"I wish that whever Jon touches the wishing stone she becomes mute, unable to make any sound at all!" The stone flared for a moment, and Jon's heart sank. Now how could she use the stone to set things right? But at least Karyn was still alive, somewhere. Maybe she would be able to find some way out of this.
"Let's test it, just to make sure. I wish that when I hand the stone to Jon, she will try to make a wish for, hmm, larger breasts, and if she's unable to, she will drop the stone." The rock glowed, and Sarah climbed off of Jon, helped her back to her feet, and then handed her the rock warily.
As soon as her long-fingered hand grabbed the rock, Jon felt her mouth form the words "I wish I had larger breasts," but no sound came from her mouth. She tried again, and again, then dropped the stone, and covered her mouth with her hands. On the one hand she was glad she didn't have even larger breasts... the ones she had now were at least a D cup and more than enough for her, but that also confirmed she couldn't use the stone at all!
Sarah bent over and picked up the rock, smiling. "I wish Jon would be unable to tell anyone else about the stone, and could never ask anyone to make a wish while holding the stone!" With these final wishes, Jon grew even more depressed. "Now, get your clothes on so we can get out of here," Sarah ordered, grabbing his pants off the floor.
Meanwhile, down in Mexico, a young Hispanic girl woke up in a hospital as a nurse checked her over.
"Wh, where am I," she whispered hoarsely.
"You are in a hospital, you barely survived an attack on your bus," the nurse replied in Spanish, which the girl understood without a problem. "You have a few cuts and scrapes, a bump on the head, but you are not badly hurt. What is your name?"
"Karyn, I think... or is it Rosaria? No, it might be... Maria Perez? My head is a jumbled mess, I, I can't recall for sure..."
"It'll be ok, maybe you'll feel better in the morning, you just rest for now," the nurse said, trying to comfort the confused girl.
