Georgie And Mandy's First Marriage Episode 9 Debunks A Long-Standing Sheldon Cooper Theory

Contains Spoilers for "Georgie and Mandy's First Marriage" Season 1, Episode 9 — "A Tire Convention and the Moral High Ground"

It looks like we were all wrong about the relationship between Georgie Cooper (Montana Jordan) and his brother, Sheldon (Iain Armitage) – at least in so far as when the connection between them fractured. Per the latest episode of "Georgie and Mandy's First Marriage," while they're destined to be completely estranged as adults, it seems that just after Sheldon's departure for CalTech, the brothers are still on speaking terms. At least, that's what some dialogue in "A Tire Convention and the Moral High Ground" indicates.

In the episode, Georgie is sent to a tire convention in New Orleans with his father-in-law, Jim (Will Sasso). Georgie, nervous about making a good impression on the tire manufacturers, tells Jim that he called his younger brother for advice before they left. Apparently, Sheldon gave Georgie some key Korean phrases that might help open some conversational alleys with a stranger. As for how Sheldon knows Korean, Georgie feels it best not to ask.

While "The Big Bang Theory" tells us that Georgie's resentment toward Sheldon over leaving him alone to cope with their family — which will eventually lead to a full-on no-contact estrangement between them — the split was not immediate, as many fans and theories have suggested. But another kind of familial rift — the sort the show has been teasing since Episode 2 — may threaten the Coopers' peace sooner than later.

During the course of "A Tire Convention and the Moral High Ground," Georgie discovers that the tire convention is basically a lie Jim tells Audrey (Rachel Bay Jones) every year so he can gamble in Mexico without her nagging him. That means Georgie's left Mandy (Emily Osment) alone to care for Ceecee while working her own job without a single by-your-leave. But Audrey already knows the score and tells Mandy. While Mandy's reaction is to believe that Georgie will be honest with her when he arrives home, unfortunately, he lies to her on the phone about the situation, leaving her fuming. Her mom's own feelings about the situation also come out in the form of a drunken binge.

Georgie, meanwhile, proves to be a natural at blackjack. He tries to confess to Mandy one more time, but fails to because he can't reach her on the phone, instead reaching Conner (Dougie Baldwin) (a character series fans have a big problem with), who's watching CeeCee. They all maintain plausible deniability regarding the convention lie once they get home — but Georgie uses some of his gambling winnings to buy Mandy diamond earrings.

Once again, the foundation of the Cooper marriage looks a little shaky. Things do work out well in the end (for now), allowing the couple to pass yet another milestone and rule out one more reason for their eventual, inevitable divorce. Time will tell what the final straw proves to be.
