12 hour twins?

Jack held the plastic bag and perused the medallion. Her pursed his lips and shook his head.
"Looks like a cheap novelty to me." He said tossing the bag back to Lisa in Jame's body.
"I assume you're not pregnant. So show me. Change." He said with an annoyed and unamused demeanor.
Lisa looked at the Medallion, then James, and then Jack.
"I guess I could switch bodies with you Jack." She said.
"Uh no. If you are my wife. Prove that you can be my wife. I'm not interested in playing these games. If what you are saying is true you asked for trouble. I did not."
James in Kim's body undressed slightly, handing Kim in James' body her blouse. James retained a silk undershirt.
"Maybe we should...." Kim started.
"Just get your game over with." barked Jack. "I've been very patient I think."
Kim held the blouse in her left hand and the bag with the medallion in her left.
She closed her eyes and began opening the bag.
