Explanations

Karyn nodded and boomed, "Of course it's me, now explain yourself." She approached him as she spoke, coming right next to him, it was apparent that she was about 4 feet taller than his 6' height. Jon couldn't help but try to back away from her new scarier body. Jon finally replied, "I, uh, I had wished to be able to see anyone I wanted on my TV, and I watched you as a test... but you were on the phone and it was pretty boring, so I kind of, uh, used the stone." Karyn blinked, and Jon continued, "I uh... wished that you could live out your wildest fantasy until you decided otherwise... kind of stupid now that I think about it, what kind of fantasy is this anyway?"
Karyn replied frankly, "Look Jon, what you did was totally uncalled for, first, you spy on me like a peeping Tom, then you make a wish about me without asking me or considering the consequences... Luckily it didnt turn out too bad, but it was completely immoral and perverted, I cant believe you did that... Ijust...Grrrr...."
Jon looked down in shame and said, "I'm really sorry Karyn, I guess all the power went to my head... and I cant help being a pervert, I'm a teenage boy..." He shook his head then continued, "Karyn, please dont be mad... Just help me find the stone so we can fix this..."
Karyn thought for a minute, then said, "I forgive you Jon... I'm really mad, but you are my best friend... but if I'm right, the stone is gone..."
Jon looked perplexed, and just managed a weak, "Huh?"
Karyn grinned, "Jon, you wished for me to live out my wildest fantasy... Well, I was daydreaming earlier, after you showed me the stone... I imagined myself as the one who received the stone... In my fantasy I had wished myself to be an immortal humanoid dragon with sole and complete power over the stone, which caused the stone to disappear and the very essence of it's magic to enter my body." Jon pondered that for a second, and said, "What made you think of that wish?" Karyn shrugged and said, "I have always been into dragons, and I guess I was a little power hungry myself."
Jon was still running through his head what was going on... he mumbled, "So, you obviously made yourself a really cool house, but where do I fit in to your fantasy?"
Karyn grinned again, showing her long sharp teeth, and spoke, "In my fantasy, I had wished you to be my dragon mate." Jon's eyes went wide and Karyn noticed, she added, "Uhm, you see... We have been friends for a really long time, I have had some boyfriends, but I have always hoped you would ask me out, but I thought you would laugh at me if I told you. John, I think I'm in love with you."
Jon stared at her for a minute, causing her to become a little uneasy, then he said, "I have felt the same way about you, ever since 7th grade I've wanted to go out with you, but I always thought you would just laugh at me if I asked..." Karyn looked into Jon's eyes and saw that he was completely serious, she laughed and grabbed him in a big bearhug, shaking him up and down. She must have hugged him too hard, because his back emitted a loud pop and he cried out in pain. She quickly carried him to the huge bed and set him down. He looked up at her through his tears and said simply, "Ow." She wished for his injury to heal, and he instantly felt better. He said, "Be careful next time, Karyn... and, I was thinking, if you wished me to be your dragon mate, why arent I a dragon like you?" Karyn thought for a second, then said, "Oh yeah, in my daydreaming, you had requested to be able to return to your human form so you could live with your parents. But we also made sure they wouldnt mind if you come to my house for as long a period as you want, whenever you want." Jon nodded, and said, "So what do we do now?"
