Georgie and Mandy are getting their own spinoff series, impacting Young Sheldon season 7. Despite Young Sheldon's high ratings, the show is ending to make way for the spinoff. The spinoff will stay true to The Big Bang Theory canon and focus on Georgie and Mandy's journey as parents. 

Their storyline in Young Sheldon was well-executed, and the spinoff will allow for more creative freedom. In Young Sheldon's final season, Georgie and Mandy's engagement sets the stage for their future as new parents and possibly a wedding.

With the spinoff continuing their story, Young Sheldon season 7 can focus on resolving other characters' futures.

 Georgie's future with Mandy may not be bright based on previous hints, but the spinoff could potentially change that. Young Sheldon season 7 premieres on February 15, continuing to explore Sheldon Cooper's childhood and family life in Texas.
