Sheldon's time in Texas is done but arguably Young Sheldon's biggest mystery remains unresolved and it has narrative implications for The Big Bang Theory. Five years after The Big Bang Theory ended in 2019, its prequel series also wraps its run. The decision to pull the plug on Young Sheldon remains divisive, with star Annie Potts voicing out her criticism of it. That said, Young Sheldon's end is due to the established timeline by its parent series. Interestingly, however, the prequel isn't exactly great in terms of preserving continuity, making this reasoning more controversial.

Nevertheless, the writers insist that both shows are tied together, hence why Sheldon's story is prioritized in Young Sheldon's final hour. Before that, George's dreaded death finally happened, despite being one of the best characters in the series — yet another detail established in The Big Bang Theory. Georgie and Mandy's upcoming sequel series titled Georgie And Mandy's First Marriage can reveal more details about what happens to the remaining Texas-based Cooper family members on the heels of the Young Sheldon ending. However, there's one particular plot line from the prequel that will likely never be resolved after it wraps up.

Due to Young Sheldon ending in a shortened year, the writers had to discern which plots were going to be prioritized. Understandably, the focus of season 7 was mostly on the Coopers, and setting up Georgie and Mandy's spinoff. However, while she isn't part of the clan, Paige's arc is one of the best original stories from the prequel. Since Sheldon is no longer in Texas and Missy isn't going to be a series regular in Georgie and Mandy's First Marriage, the chances of Paige's narrative getting a proper closure in the offshoot are very little to none.
