At first Jon considered just leaving Sarah the way she was as punishment for what she did to him. After all, he thought, she'd deserve it.
But then Jon remembered the stone. Sarah still had it and even though Sarah didn't fully understand how to use it, she could do terrible damage with it, especially if Jon couldn't hear the wishes that she made. If he wasn't careful, he could wind being completely controlled by Sarah.
"Ok," said Jon, "I'll make you your normal size again. But you got to promise that as soon as I do, you give me back my stone."
"Give you the stone!? Like hell --" Sarah paused. "Uh, yea, on second thought, sure. Of course. I mean you're fixing my height and all. It's the least I should do."
"Alright then" said Jon and he aimed the gun at Sarah and focused on her whole body. He pulled the trigger.
Sarah slowly began to grow. 2 feet. 3 feet. 4 feet. 5 feet tall. When Sarah reached 6 feet tall, Jon stopped.
Sarah jumped for joy and rushed to the mirror to check that she really was human sized. "Oh thank God!" she cried out.
Jon cleared his throat loudly. "Uh Sarah, the stone" His hand was outstretched expectantly. Sarah turned to face him. The 25 year old twins stared at each other. They were exactly the same from the golden blond hair to the perfectly manicured toes. The only difference between the two was that one held a stone and the other held a shrink ray gun.
"You know what Jon, screw you." Said Sarah as coldly as she could "You come over to MY house, and watch ME through MY window, like some perverted little peepshow. If it wasn't for you, none of this would have ever happened. So you know what, No. I'm not handing over this stone."
"If it wasn't for ME?!?!" cried Jon in shock, "YOU'RE the one who came over to MY house and stole MY stone! How DARE you pin this all on me. This is all YOU'RE fault! Now GIVE ME MY STONE!"
"You know what Jon, I wish..."
