"Stay there, I'll be right back." Jon got up and went to the next room as Karyn had before.
Karyn casually glanced around Jon's room, wondering how long it would take. To her surprise, he returned only a minute or so later. "Well?" he asked.
"Well what?" she replied.
"Notice anything different?" he asked, smiling slyly.
"Let's see," she replied. She walked over to the same mirror, and looked herself over critically. As far as she could tell, she looked the same as she always had. "I don't see anything different at all," she confessed. "What'd you do?"
"Okay, one more question. Tell me if you know what this means." And with that, Jon spouted a couple of lines of what soundd like utter gibberish.
"What in the world was that? It sounded so - so weird!"
"It was the opening lines from 'Star Trek' - you know, 'Space, the final frontier,' and all that."
"What language was it?"
"English."
"Oh, don't be ridiculous! If that was English, then what are we speaking now?"
"Well, Karyn," he said, his grin widening, "Since we're now both Korean, what do you think it might be?"
"Huh? What do you mean - wait, did you..."
"Yep," Jon said with a laugh. "When I left the room, you were white - I used the stone to make you Korean."
Karyn looked at herself again. The Korean girl staring back at her certainly seemed like the one she saw every morning in the mirror - except for the blonde hair and bigger bust she'd accidentally given herself, at least. But she had made Jon think he was white for a while, so it was certainly possible. "But if that was English, why did it sound so strange?"
"Part of the wish was that we could both speak and understand Korean fluently, but that you could no longer speak or understand English for the next half hour."
"So I'm going to look like this for a half an hour?"
"No, you'll get your language skills back in a half hour, but you'll stay like this until tomorrow morning."
"Why?"
"No particular reason - I just thought it'd be cool, y'know?"
