Obi-Wan TV Show!

It has been confirmed that Ewan McGregor is back as Obi-Wan Kenobi in a Disney+ show. I realize the show will be set on Tatooine, but I hope they find an excuse to have him go to a few other locations. Is there anything in the original trilogy where he says that he never left the planet? 

I would love if they found a way to explain to us why he never goes after Vader (once he learns that Anakin survived). Also, we need the falling out between Uncle Owen and Obi-Wan. I realize this stuff could have been in the cartoons, comics, and books. Unfortunately, I am not as versed in Star Wars as I was back in the olden days.
