The "Upscale Patron" in a later episode might be a pivotal flashback or something like that.
I had never considered that being her stunt double. Could be.
Now that Peacock has released The Paper, I'm expecting we're not too far away from a trailer. According to Peacock's Wikipedia page, there isn't much of their upcoming programming that has advanced to post-production (only The Copenhagen Test). It says The Miniature Wife is still filming, but we know that's true, and it probably just hasn't been updated yet.
Peacock chose to release all 10 episodes of The Paper at once, but I'm hoping they don't do that with The Miniature Wife. I believe it will be more fun for us to discuss each episode individually than for us all to be at different places. Some of us don't have the ability to binge 13 hours of television as soon as the series drops, and I'd rather we be in sync and draw this out as long as we can.
