Steve Holland, co-creator of Young Sheldon, revealed why Paige Swanson was missing from the final season. Mckenna Grace played Paige, a child genius, since Season 2. Holland explained that Paige's storyline didn't have closure due to the shorter final season and Grace's busy movie career. Fans loved Grace's performance, making Paige a popular character. Holland mentioned that it was challenging to bring Paige back, given Grace's movie star status. The show's finale was emotional, and a spinoff featuring Georgie and Mandy was announced.
