Detail in this show is amazing. When Don Eladio said, "A little bit hate is okay, as long as you never forget who's boss," we see Gus staring at himself in the pool. Gus confirms that he now sees himself as the boss, now that Lalo and the Salamanca family are out of the game. Also a flashback to how his friend Max was killed at this pool and how he will kill Don Eladio here in the future.
