Fascinating thing about Chuck is that Jimmy is still waiting for a comeuppance even if it's at the cost of alienating his relationship to his brother. Yeah, Chuck was more right in this episode than he's been before but the fact is he's still taking a somewhat sadistic glee at the idea of proving Jimmy wrong due to how amazingly self-centered he is. Really the one thing I learned about him in this episode is how it's not even really just about his pride as a lawyer but his pride in being put on a pedestal. I don't think Chuck sitting with Howard in reviewing Kim was a coincidence. He has the potential to step in at any time to influence reason in Howard's choice but he doesn't call out the rashness of it, primarily because he still wants to see Jimmy crumble.
The fact that "Chuck is right" is something that has gone without saying ever since the penultimate episode of last season, and Jimmy admitted in the first episode of this season how he wouldn't be happy with his job at D&M because his interest in the law is somewhat fleeting. He's also shown in this episode that he probably wouldn't lose much sleep if he actually did get removed from the bar. Chuck being right isn't really a big issue, the issue is that he's so proud of himself that he's starting to show shades of abandon just because he can't admit that even in the most superficial of terms, he won't ever admit to Jimmy being right.
Which is why I'm reminded of probably the most profound sticking line from last season when, again, he had to stick his neck on the line to salvage a problem that was completely out of his control (and which quite frankly he was lucky about accepting the bribe as it meant he had a smoking gun in terms of reverting damage done). "The thing you guys should know about me, I've got nothing to lose".
It's a bit of a shame that Saul's character "leaves" Breaking Bad under some of the most cheap circumstances. Even though it's inferred paranoia due to the cops baiting Huell / Kuby out of the game and fear that Todd's gang might get to him, he gets out of dodge under circumstances that wouldn't leave him in much of a bind, which means that while the development of this show up until Saul establishes his brand is going to mostly be a fairly uphill one (since he's content with where he is at by the time we meet him in Breaking Bad), the actual "downfall" passed that seems like it's going to be a bit underwhelming.
