Towards the end of Episode 3 "Theatre of Pain", when The Adjudicator arrives at The Continental by car, the licence plate reads "SW-FLTY" which likely means "Swear Fealty" and is a common theme or message throughout the John Wick Universe, meaning loyalty.
Set in the 1970s, telling the story of the New York Continental hotel, which also plays a central role in the John Wick (2014) film franchise.
Was originally meant to air on the Starz network before moving to Peacock.
The Adjudicator's kilt wearing henchman (portrayed by Kirk Ward) is an obvious tribute to the Roy Batty character made famous by Rutger Hauer in Blade Runner.
