Although the show won't come for a while, I predict Mandy and Georgie will get a divorce as Mandy isn't shown in TBBT (although georgie is only shown twice), also, I swear I remember Sheldon saying "Fun Fact, Georgie married his 1st wife at 15" which implies he had more than 1. Lastly I think Mandy took baby Cece as she isn't mentioned either.
