Young Sheldon Is Ruining Sheldon & Penny’s Best Big Bang Theory Moment! Here's Why!

Young Sheldon season 6 has revived George's cheating storyline, revealing that Missy knows about her dad's secret meet-ups with their neighbor. This revelation cheapens the emotional moment between Sheldon and Penny in The Big Bang Theory season 10, where Sheldon confided in Penny about catching his dad cheating. It also hints at a possible breakdown of the Cooper parents' marriage in the future.

With the plot being too dark for a lighthearted family sitcom, incorporating it into Young Sheldon's storytelling poses a challenge. Nonetheless, unless the prequel wants to break The Big Bang Theory's established canon, it will need to address this narrative.
