Jon realized he had to do something but what. Maybe body swap them. Buthe'd have to do it smart. After all wishes cannot be reversed and if they don't hear it they will not rememberand he doesn't want them to know he has a stone. He also knew that if they easilly adapted to their new life of was accepted as how they act post switch it wouldn't really be a life lesson.
Jon held the stone and said "I wish my parents will swap bodies until i wish otherwise and both would remember their old life and everyone who knew them would remember how they were pre swap. I also wish they would have trouble acting any different from their old selves when in their new bodies."
