I was away for a few days, so I just saw the latest episode last night. I was surprised with the abrupt departure of Kim from the storyline. Definitely a "rip the bandage right off" moment. Then a jump ahead in time to show that any semblance of Jimmy is gone and Saul has completely taken over.
Regarding the wine scene and Gus. I at first thought it was intended as a sad scene because we realize Gus can not allow friendships or relationships to distract him from his goals.
But, after seeing how cold blooded and sinister he was in BB, I wonder if he doesn't enjoy toying with people making them think he is a kind, gentle, generous man. He has moments as the Chicken Man supporting charities in the community or with the police where everyone says what a great guy he is. Those people and the ones at the restaurant would be shocked to learn the truth about him.
I think he enjoys leading a "double life" and fooling so many people. He was talking about wine with the guy and when he walked away to get the bottle, Gus' eyes went black and he was back to being Gus the drug lord and left.
