The most recent update on Young Sheldon seems to confirm the death of George, Sheldon's father, in season 7. George is an intriguing character in The Big Bang Theory universe, although he never physically appears in the show because he had already passed away before the events of the series. However, thanks to Sheldon and Mary regularly sharing stories about him when he was alive in Texas, George was already a well-established character. This has resulted in some inconsistencies between the two shows.

Iain Armitage, the actor who plays Sheldon, is already 15 years old, while Sheldon is turning 14 in the spin-off.

This age difference between the actor and the character poses a challenge in terms of storytelling. To address this, the show may choose to do a time jump, but this could complicate things due to the eventful year that Sheldon and the Coopers had when he was 14. 

To provide a satisfying conclusion to the series, Young Sheldon must cover all the important moments in the Cooper family's history that were established in The Big Bang Theory. Additionally, the show needs to address lingering plot points, such as Georgie and Mandy's upcoming wedding and Missy's redemption arc.

Tackling such a tragic event like George's death is a risky move for a comedy series.

It may be considered too dark for a lighthearted show, especially given the contradictory depictions of George in The Big Bang Theory and Young Sheldon. While his death will undoubtedly be sad, it is crucial for the continuity of The Big Bang Theory canon and the Cooper family's story. George's death sets up many future events, and deviating from this established continuity would fundamentally alter Young Sheldon's characters and their futures.
