Incomplete wish

When Jon and Karyn made that wish, it was so long that they had to breath in the middle of the wish. But since the stone only counted a wish up until a change of breath, only the first part of their wish was granted. They could enter a story by saying "yawa", leave a story by saying "emoh", they could be any character they wanted to be, and they could change the story. But they could not bring things out with them from the story, their lives were not safe withing the story and whatever changes they made to a story became permanent changes. Jon and Karyn didn't know that the last part of their wish had not been fulfilled.
