Damn.
I had a strong sense Chuck might die (and who knows, he may still live...), but I thought he was going to accidentally electrocute himself while tearing up his walls in a fruitless search for the electrical source, not by deliberately starting a fire in his own home. In between those moments, I thought his further downfall would follow from the ardent destruction of the electricity meter depending on who owns it, although in retrospect I wouldn't be surprised if Chuck managed to arrange ownership of it. Either way, Chuck has fulfilled Jimmy's prophecy: He has pushed away everyone in his life (Rebecca, Howard, Jimmy, Ernesto) and now he's going to die alone, shuttered away in his torn-apart home. On a side note, nice bookending with the lantern.
Jimmy, upon realizing he's only good at destruction and not creation, fell on his own sword in order to restore Irene's reputation and friendships. He simultaneously showed how much he does care about the people he's helping by showing how much destruction he already created. It was the only way to help Irene, but he has ruined his own reputation even though he still cares about them. And I have to wonder how much Kim knows about the whole situation. She seems to know what he did during chair yoga with Erin, but does she what he did in the first place?
The office is closed. Although for a moment, Kim was about to jump right back into the insanity she created, she pulled herself back, realizing she absolutely must have a breather now. She nearly died because she overworked herself. Now she has lost her second client, although apparently not her reputation. Despite Francesca's assurances that a lot of people die on that road, I can't help but wonder if there's some question from the outside about the nature of Kim's accident. Not only were there no other cars involved, no other cars were even around, as evidenced when Kim stepped out out of her car and no one was around. I wonder if that will become an issue next season or if I'm just overthinking the situation.
And at long last, Hector has suffered his fated stroke. Nacho seemed to have lucked out, especially since he was about to go with cold blood murder. But he may have another problem: Gus clearly suspects there was malfeasance involved. Speaking of Gus, I was slightly surprised how quickly he leapt into action to save Hector. All a cover for Juan Bolsa, and by extension, Don Eladio, I'm sure, but I was still slightly taken aback.
