Gus!

Why was Jimmy so nervous, hopeless and obvious about watching the guy in the diner? It seemed totally at odds with his character.

Because the switch in his old office was left on Nervous Surveillance mode.

I understood ultimately what he was trying to achieve by turning the tracker on themselves, but I don't understand how he did it. How did he do it? I might have been distracted at the time/an idiot.

Shoes and sniper rifle was awesome.

Saul Goodman appears for the first time.

We're now seeing a real transitional phase for Jimmy, fascinating to watch (him putting him the boot into Chuck at the end via the insurance company was genuinely nasty), and also the first cracks in his situation with Kim. Lovely scenes with Mike too and the grief-stricken widow.

Really well done how they've shown Jimmy trying his best to keep things ticking over but getting squeezed into taking the inevitable dodgy path.

Chuck dead though!

Shame to see chuck loose it and die after he had secured a payoff in the millions and appeared to be ok.

Have to wonder if Jimmy will get his class action money, I would say not, as surely he would not be doing the cheap arsed lawyer work he was in BB if he had picked up a million dollars?

Well that's the point with Chuck, he'd basically lost everything, as HHM was everything to him. He didn't need more money as he was already fairly wealthy, he wanted back in at the firm but Howard outmanoeuvred him by coming up with the cash, which Chuck knew the firm didn't have so wasn't expecting, but Howard bought him out with his own cash and loans. Chuck's final show of power was to belittle Jimmy, 'You were never that important to me', and with Jimmy gone, Chuck had nothing.

As for Jimmy's Sandpiper settlement, he gave it up because he could see what he'd done to Irene at the home, he thought he'd be able to get the other ladies back on-side after he'd secured Irene going for the settlement, but they wouldn't budge. As such he sacrificed the settlement to save Irene.

I thought that Jimmy was just trying to push the Sandpiper settlement early rather than wait for the money? I figured that he will still get paid out at some point in the future when the case gets settled?

I can imagine that there will be drama linked to what happens to Chuck's money, I wonder whether his will would say Jimmy can get his money if he does [x]. Or maybe HHM interferes and gets the bulk of his money, and maybe offers Jimmy some of it if he agrees to [y].

I'm not aware that Jimmy and Chuck have any other family so you would think Jimmy would get the money.

But last night before he told Jimmy 'You were never that important to me' he was doing paper work at his desk so I wonder if he was cutting Jimmy out of his will.

Right. I doubt he would cut him out entirely. It'll be "you have to do something that means I get the last laugh in order to get the money", Jimmy will just refuse because he doesn't need the money, but then circumstances will develop that he needs the money (to help Kim with something), and have to do whatever Chuck wanted in the end. Somehow his relationship with Kim will become fractured and he'll begin his full on descent into Saul Goodman.
