Obviously, Georgie's new business partner (as established in <em>Georgie & Mandy's First Marriage</em>'s season 1 finale), Ruben, wouldn't have been mentioned in <em>The Big Bang Theory,</em> as at the time, <em>Young Sheldon</em> hadn't started, let alone the Georgie-centric spinoff. However, in <em>The Big Bang Theory</em>, Georgie is running the Dr. Tire franchise. Note, it's Dr. Tire, singular, not plural. Of course, it could just be something as simple as Ruben eventually retired, as he's older than Georgie, but I wonder if something happens between them later on.
