George and Brenda’s potential affair was the focus of Young Sheldon season 5’s earlier episodes, stemming from their flirtatious evening in the season 4 finale. While the pair hasn’t done anything wrong, technically, The Big Bang Theory spin-off made it clear that there’s a genuine attraction between them; it’s just that neither is acting on it. While Young Sheldon season 5 may have not offered the payoff that viewers were expecting with this arc, it seems like the intention is to play it out longer, perhaps leading to George’s eventual death. With two more seasons of Young Sheldon already guaranteed, CBS has more than enough time to tackle this narrative. This way, George and Mary’s marriage doesn’t get destroyed in an instant, but gradually over time.
Assuming that Mary retains her new job at the bowling alley with Brenda, then it will be interesting to see if she ever finds out about George’s relationship with her. It’s worth noting that after the Cooper patriarch suffered the small heart attack in the Young Sheldon season 4 finale, neither George nor Brenda told anyone what really happened that night. Meemaw had some suspicions, but she never found anything; otherwise, she would have already said something about it. Given this, expect that Young Sheldon season 6 will further delve into Brenda and George’s evolving relationship and how it impacts the Coopers.
