Jon gestured to the boobs and blonde hair she'd accidentally given herself, "Oh really, because you've been so good at it so far!"
"Jesus Jon, you always think you know best," Karyn complained. "Like you've ever had to make an important decision!"
"I make important decisions all the time," Jon yelled. Even if that wasn't really true, he was getting angry at this point, "My life's pretty complicated!"
"Well guess what, it's not always that easy being me either. God, I wish you'd lived my life and could see what I was talking about!" Karyn had one moment for eyes to widen in shock before the flash of white light overtook the pair.
When it cleared, Jon's room looked completely different looked about the same. But the boy and girl in it did not. The girl looked a bit like Karyn, but she was wearing a skirt.
The boy, who looked like, but not like Jon, grabbed the stone away from her. "What did you just do, Jenny? I feel weird, all of the sudden..."
Jenny looked at him. "There was a wish, but...everything looks the same, I think...it feels different, but..."
Ken frowned. "Maybe we'd better put it away before anything else happens."
