"I wished to have the ability to swap body parts," said Jon. "It works like the wand, everyone else thinks it's normal... only I accidentally swapped with my Mom."
"Hey, you're finally calling her Mom," said Karyn.
"What do you mean?"
"Your stepmother."
"What? She's my Mom. My real one. Gave birth to me and Mikey, you know."
"Come on, Jon," said Karyn. "You told me months ago that your Dad married a she-male. I don't think she could have given birth to you."
"HUH?"
"Jon? Is something wrong?" wondered Karyn.
Then Jon realized. If he had swapped genitals with his mother, and if things had been like that all along... then his mother would have had his parts and couldn't really be his mother. "Karyn! I think I messed something up. Please... tell me what you know about my family..."
