Georgie & Mandy’s First Marriage co-creator Steve Holland addresses a key piece of continuity between the Young Sheldon spin-off and its predecessor. Spinning out of the events of the Big Bang Theory prequel, the sitcom follows Montana Jordan and Emily Osment’s eponymous young couple as they raise a family together. Set a year after Young Sheldon‘s finale, several main cast members of the original show have reprised their characters in guest roles throughout Georgie & Mandy’s First Marriage‘s first season.
