The show already features two alumni of That '70s Show, so why not a third?
- Confirmed, sort of. After Rooster is offered a job at a corporate ranch, Valderaama plays an employee who works for Ed. He also worked for Beau for ten years, but is named "Berto" or Umberto, not Pedro.
- Why not add Mila Kunis as another love interest for Colt while they're at it?
It's a common sitcom plot, Beau is being set up with high blood pressure, and Sam Elliott is also on Grace and Frankie. If the boys take over the ranch, Beau's role will be reduced, or they could kill him off.
- Sort of confirmed as of Part 4. Beau has a "cardiac episode."
He is heavily resistant to change, has trouble communicating, is fixated on one particular thing (ranching), freezes up when hugged and is a picky eater.
- You seem to be describing the Grumpy Old Southerner stereotype
