"No, wait," said Karyn. "I have a better idea. Stop and come back, then sit down. And remember the stone again, but don't ever use it."
Sarah obediently sat down, but tried to yell out "What are you planning?" But she still couldn't exceed a normal voice.
"You wish Jon would become a sperm and fertilize me, so I'll give birth to him. You also wished my next child would be a girl. You forgot something."
"What did I forget?" said Sarah.
"Think about it."
Sarah was looking at Karyn suspiciously. "Tell me!" The tone in her voice was angry, but she couldn't yell.
"Fine, I'll tell you. You never wished Jon would be my next child. What if I have twins and Jon is the second one, and the first is a girl?"
"You're not going to..."
"Yes, I am, Sarah. I wish that Sarah would become a sperm, and be transported into me where she would fertilize one of my eggs, and be my biological child. I wish that she'd keep all her memories, but have to act like a child her age. I wish that I would give birth to her right before Jon, and that Jon would be born as a boy."
And Sarah McMillan disappeared.
