I have a question, which I could probably answer myself if I went back and re-watched season 3, but I don't really have the time to do that. Mike made the comment before Walt shot him regarding "we had a good thing with Fring, but you had to be 'the Man' and ruin it".
Is that an accurate portrayal of the history, or just something that fits the mindset and the personalities after-the-fact? I can't really remember what it was that made the relationship between Walt and Gus go so bad, so fast. Why didn't the "good thing" last, at least longer than it did? Because rationally, it seems like it should have. It was a good situation for everyone to make a lot of money in a well-run organization.
I have this vague sense that it was because Jessie was a screw-up and Gus wanted him out, but Walt was protecting him? There must have been other reasons, because Jesse eventually gets to be in Gus' inner circle.
Reading the
season's synopsis on wikipedia is not refreshing my memory. It goes from "As for Walt, he realizes that his life was in danger and that it was only Gus' intervention that saved him" to "Gus, invites him to dinner and dispenses sage advice" to just two episodes later Gabe is getting shot to keep Walt from getting whacked by Mike.
