Instantly, Jon understood what had happened. When he'd drawn the Switch card from Lydia's party bowl, he'd been in contact with two magical items at once: the card and the stone. And because he wanted to follow the instructions on the card, no matter what they were, the stone had multiplied the card's effect.
Unfortunately, neither the Switch card's effects nor the stone's effects were reversible. Everyone was stuck in the body they now possessed. Jon, however, could still use the stone to with for anything else he wanted.
At that moment, what Jon wanted most was to go home, but to his own home, not Sandra's. That would only be possible, however, if Jon's mom, dad, brother, sister and everyone he knew thought that Sandra's body -- not Jon's -- had grown up in their family and in their house. That body, after all, was the one Jon now possessed.
But in that case, where would his original body have come from? In the simplest case, Jon would have to be born to Sandra Swanson's mother, grow up in the Swanson family, and live in the Swanson house.
But if Jon and Sandra grew up in each other's families, would they still develop the same personalities? Would Jon still have grown up as a mild-mannered person, or would he develop a dominating personality such as a bully or a sadist?. No doubt something in Sandra's background had made her grow up as a dominatrix.
Growing up in Jon's family, would Sandra still become a dominatrix? Or would she have a milder personality?
And if Jon and Sandra both grew up with different personalities, would the Switch card still affect them the same way?
And what about the stone? If Jon was born to Sandra Swanson's mother and grew up in the Swanson family -- presumably as Jon Swanson -- why would Jon's original grandfather leave the stone to him? Wouldn't Jon's grandfather leave the stone to someone within his own family?
Most likely, Jon's original grandfather would leave the stone to his daughter Linda Madison, Jon's original mother, or to one of her children -- Zoe, Mikey, and now Sandra -- or to someone else in his extended family. The new Jon Swanson wouldn't even know the stone existed.
Then again, Jon hadn't actually been Jon Swanson before the Switch card had done its work, and he wasn't after. He was Jon Madison in Sandra Swanson's body. And even if he changed other people's memories so they thought of him as Jon Swanson, that didn't change him. He'd still be Jon Madison, living in Sandra Swanson's body, but in his own home as Sandra Madison.
In the end, Jon didn't care about the details. He only wanted to live in his own home and sleep in his own bed. And so, while touching the stone, he whispered, "I wish everyone, especially my original parents, would think Sandra's body (which I have now) belonged to Jon's original family, and that this would have as little effect on everyone else as possible, and that I would retain knowledge and possession of the wishing stone."
The instant Jon finished uttering his wish, he felt a wave of power pass through him, then he looked around the room and the group for obvious changes. He was still in Sandra Swanson's body, and he was still wearing her black corset, black miniskirt, scarlet fishnet stockings, chrome spike heels, and riding crop, and he still had the stone and knew what it was. However...
