Switching Families

Meanwhile at the mall, Jon and Karyn were eating in the food court, talking about all the things they could do with the wishing stone. But a few minutes into their meal, Jon turned into a freckled redhead and no one noticed. Jon can't have a mother that is younger than him, so as part of his mom's wish, the stone reassigned her children to different families. Jon looked like a younger male version of his new Irish mother. He had no memory of his original mother, Zoe, or Mikey. What happened to his former siblings? Whose children were they now?
