Quickly Sarah came up with a plan, "I wish that Jon would only make wishes that I want and when I want and that he won't let anyone else use the stone" she said and quickly returned the stone to Jon's hiding place.
The stone flashed and a ring appeared on her finger. There was no time to worry about it as Jon walked in with the drinks.
Sarah put up with Jon for a bit before making an excuse to leave, tomorrow would be fun she decided.
