Several Young Sheldon characters are returning in Georgie and Mandy’s First Marriage. The Young Sheldon spinoff series will focus on the Coopers’ eldest son as he begins married life with his wife and baby. Its title suggests a rocky road for the couple, likely ending in divorce to match the backstory for Georgie set up in The Big Bang Theory. Its events will take place after Sheldon leaves for Caltech, making it unlikely the young genius will appear, despite star Iain Armitage being open to reprising his role.
It was initially unclear whether any of Georgie’s family would appear after the Young Sheldon finale explained that the young couple would be starting their own life. By then, the pair had already moved out of the Coopers house and in with the McAllisters, who lived across Medford. Georgie and Mandy’s First Marriage is supposed to be different from Young Sheldon, so it seemed unlikely that many stars from its predecessor would appear. As more information about the sequel spinoff came out, however, it was revealed that several Young Sheldon characters are coming back, at least as guest stars.
It would have been strange to omit Mary Cooper from Georgie and Mandy’s First Marriage. The Cooper matriarch was a big part of her children’s lives, and that would have been doubly true after the tragic events of the Young Sheldon finale. Mary suffered the double blow of George Sr.’s death and Sheldon going to Caltech, so she needs something to fill her time. Thus, she would likely annoy Georgie and Mandy by showing up all the time to check in on her granddaughter. Mary will likely also butt heads with the McCallisters, particularly if she shows up uninvited.
Initially, it didn’t seem like Mary would be part of the sequel series at all, but it has been announced that Zoe Perry is returning for the premiere episode of Georgie and Mandy’s First Marriage. It remains to be seen whether this is a one-off appearance to help usher in the newest show in the Big Bang Theory franchise or Mary will be a recurring character.
