Zoe didn't remember, but when she took Jon's stone, she made a wish to give Jon another stone (that's the stone that Sarah found later and then used to turn Karyn into Ethel and Jon into Bambi). She didn't know that her wish would be granted. She just muttered it, thinking out loud that she wished that Jon had another stone so that he didn't notice that the original one was missing. The new stone was a wishing stone, but it didn't work exactly like the original. For one thing, wishes could be reversed and contradicted. With the original stone, wishes were permanent and could only be reinterpreted.
Athena handed the stone over to her friend.
Zoe looked closely at it, then sighed. "I wish ..."
