Before Georgie & Mandy’s First Marriage begins, it is worth looking back on what Young Sheldon and The Big Bang Theory told viewers about the series. Young Sheldons spinoff Georgie & Mandy’s First Marriage is in a unique position. The CBS sitcom takes place after Young Sheldons finale, but before the beginning of The Big Bang Theory. By The Big Bang Theorys finale, Sheldon had reconciled with his older brother Georgie. However, the pair were estranged throughout most of the shows original run, meaning not a lot was known about the mysterious older brother Sheldon left behind in Texas.
