Karen started to walk away to help an other table. Jon/Shelly didn't know what he could say to her to amke her believe. he had and idea and started to dig through the purse franticly.
"Karen wait!" Jon pulled the stone out of the purse. "I have this. See. I'm..."
"Jon???" Karen filled in the blank.
Jon nodded in agreement. "Thanks to the last wish, I don't seem able to say my name. Well, I can say it's Shelly, cause well...look at me?"
Karen kinda give an sideways look at Jon, "and you wished for that?!"
"No no no no, well not exactly," Jon tried to explain, "Let's just say it was the result of several poorly worded wishes"
Karen sat down at the table across from Jon no longer worring about her other customers, "So, what are you going to do?"
"I'm not sure," Jon started, "I don't think I can wish my self back since I can't say my name."
