Summary
With one secret cameo at George Sr.’s funeral,Young Sheldonpoked fun at the show’s biggest unsolved plot hole fromThe Big Bang Theory. ByYoung Sheldon’s series finale, the show still had not managed to explain every inconsistency between itself and its predecessor,The Big Bang Theory. The change in Meemaw’s personality between shows remained a mystery, as did the cause of Georgie and Mandy’s eventual divorce. This might be explained in the upcoming spinoffGeorgie & Mandy’s First Marriage, but other lingering questions remained open by the show’s final outing.
One of these unanswered mysteries was the question of why Sheldon talked so poorly of his father despite what a good man George Sr. was throughout the series. Another was whether Sheldon ever discovered that his father didn’t really have an affair, or if he was unaware of the mistake he made when he walked in on his parents engaging in some role-play. TheseunresolvedYoung Sheldonplot holeswere annoying, but the series did manage to fix the biggest inconsistency between the two shows. Not only that, but the penultimate episode also had time to joke about this issue.

For years, viewers wondered how Lance Barber could play both Leonard’s high school bully inThe Big Bang Theoryand Sheldon’s father inYoung Sheldon. Barber appeared as Jimmy Speckerman inThe Big Bang Theoryseason 5, episode 11, “The Speckerman Recurrence,” years before winning the role of George Sr. inYoung Sheldon. The question of why Sheldon didn’t recognize Jimmy as his father was explained whenYoung Sheldoncontinued to recast actors fromThe Big Bang Theorythroughout the spinoff’s seven seasons, proving that a lot of people simply had doppelgängers in the show’s fictional universe.
This wasn’t the first time a George Sr doppelgänger showed up in the show’s universe and the gag allowed Young Sheldon to admit that the spinoff tends to recycle actors.

The series acknowledged this with a meta gag whenLance Barber played a female mourner at George Sr.’s own funeral in a blink-and-you’ll-miss-it cameo. This wasn’t the first time a George Sr doppelgänger showed up in the show’s universe and the gag allowedYoung Sheldonto admit that the spinoff tends to recycle actors. It is not yet clear ifYoung Sheldon’s spinoffGeorgie & Mandy’s First Marriagewill also utilize the same actors seen inThe Big Bang Theoryin new roles again, but Barber’s cameo proves that the shows don’t take their shared universe too seriously.

SinceYoung SheldonandThe Big Bang Theoryare set multiple decades and states apart, a handful of similar-looking people isn’t a big deal in their shared universe.

As a result,not all ofYoung Sheldon’s storylines workedas they clashed with the original show’s existing canon. In contrast, the same actors playing various characters in both shows wasn’t an issue. Instead, this affordedYoung Sheldona chance to offer viewers ofThe Big Bang Theorysubtle Easter eggs like Barber’s hidden cameo at his own character’s funeral.
