They all looked at each other and decided to call themselves by the names of the people they occupied as they made there plans.
The two that were Dana and Ricky(Cindy Rhodes) were all ready clear with the police so they did not have to go to clear things up.
Where as Jack still had to get clear about his new appearance and Sharon had to be cleared about not being with Rick any more.
So it was decided that while Jack and Sharon went to the police station to tell the story that would clear them from having the police looking for them the two left behind would start the look for the car that Ricky said the medallion was in.
Meanwhile Jack and Sharon would blame everything on Rick which they know no longer existed and say he had kidnapped Jacob who no longer existed as well so the four of them would be free to look for the medallion.
