GREETINGS, BOY.
Who are you? thought Jon (in Karyn's body).
I AM THE POWER THAT LIVES IN THE STONE. YOU HAVE DISPLEASED ME BY WISHING AWAY THE TRUE GUARDIAN. SO I MUST PUNISH YOU.
Punish me? How?
I WILL MAKE EVERYONE THINK THAT WHAT HAS HAPPENED NOW HAS ALWAYS BEEN THIS WAY. AND THEN I WILL LEAVE.
What? thought Jon for a second, and then it hit him. It's going to make me stuck as Karyn! That's its punishment!
The stone flew out of Jon/Karyn's chest. She made a grab for it but it vanished.
"Great." said the new Karyn. "Well, I guess I'll have to live like this from now on..."
THE END (I think...)
