On the drive home Shirley had a thought. "How about we play a trick on Max. Let's pretend we didn't find any clues and also pretend it was only Shirley that magically changed. I'll pretend I'm you"
"He'll know straight away that you're not me"
"You think?"
"Yeah"
"Want to bet?"
"Not really"
"I bet you he won't find out till morning who I really are. If he does I'll give you ownership of this car"
"Oh!" Krista perked up "You've finally decided to upgrade? But what do I lose if he doesn't find out?"
"The medallion. You give me the medallion. Mind you no car if you let on that you are not Shirley magically changed into Max"
"But I don't own the medallion. Max found it"
"Don't worry about that. I'm sure I can covince Max to gift it to his girlfriend"
"Okay. If you can convince Max to gift you the medallion and he doesn't recognise that you're a phoney Krista then it's a deal. What car are you thinking of?"
