Jimmy and Chuck remind me of the legend of the two fighters tied together by the length of a turban, they hack away at eachother, but one cannot wound the other without being wounded himself.
Also, Gus is baiting the hook, he is so good at figuring out what makes people tick. The draw will be revenge on Salamanca.

And maybe just a little bit of sibling rivalry thrown in the mix. Chucks identity is so tied up in being a good attorney. Jimmy must never, ever be given the opportunity to surpass Chuck. That's the one possibility that can bring him out of hiding.

Yep, in the ER they had the efficient condescendtion by the medical staff down pretty well. Yep you're hurting and terrified, but you're broken and we need to fix you. So stop babbling about what you want.

Except that Chuck tries to sabotage every effort on Jimmys part to rise. Jimmy must be kept down, just like the dishonest part of Chuck must be kept down.
