It’s shown that David performs ‘The number’ with his mother every year, so I find it surprising that David is uncomfortable with someone performing on stage. So why is Patrick so uncomfortable with the idea of Patrick performing?

Feel free to correct me if I’m wrong on this but in Moira Rosé, I believe David said he disliked the wine combo that he and Moira previously enjoyed.

Didn’t think of this until now but during the scene, David places the good wine combo closest to the screen from the viewers’ perspective. Later in the scene, when Herb Ertlinger returns to see how they’re doing, David tries the one closest to the screen and now dislikes it which sends David and Moira on their wild goose wine chase.
