Clarence (a.k.a. "Man Mountain") makes an appearance as the driver of the escort service. Clarence was one of the three gunmen that Pryce hired for a protection job in "Pimento". He was the hired gun who ran away in fear after being intimidated by Mike Ehrmantraut. Clarence was also one of Jimmy McGill's batboys hired to intimidate the gang of teenage thugs that mugged Jimmy in "Piñata".
At 38 minutes and 38 seconds into the episode Charles McGill is whistling a tune while Ironing his shirt. This is in reference to the episode 'Buyout' from Breaking Bad Season 5-A in which Walter White was whistling the same tune while finishing off a batch of meth.
