Jon couldn't be so harsh to his sister, no matter how badly they got along with each other, so he chose her fantasy.
A bright pink light filled the room. After it dissipated, Jon saw that nothing had changed. At least, nothing noticable had changed.
He looked at Karyn and then down at himself. He guessed that he expected that everyone would become Goth or something. But Karyn looked the same as always (except for her new physical attributes, thanks to the wishing stone). And so did himself.
"What is that thing?!" Zoe yelled. "What did you do to me?!"
Zoe said something under her breath and then both Jon and Karyn felt themselves being pushed back into the hall by an invisible force. Zoe's eyes went wide. She had just whispered a spell to force her brother and Karyn out of her room. And it worked! But how was that possible?
Their mom walked by in the hall at that moment. "Zoe! I told you not to use that spell anymore. Next time, just tell your brother to leave."
Zoe, Jon, and Karyn were all astonished. Magic really was commonplace.
