"Further, I wish that Linda, Karyn, Athena, and Tommy would become one person, just like I did with the Gibson family." That way, it wouldn't be strange for a 20-year old like herself to be best friends with both a 40-year old and a 10-year old (being friends with teens probably wasn't too far-fetched). And it would be easier to just have one best friend, than have four.
The stone glowed, granting her wish.
