The episode shows how “double” combines with other words to create several meanings: “double up” can mean increase an amount, “double down” means stick firmly to a position, and “double duty” means serve two purposes. “Double back” means return the way you came; “do a double take” means look again in surprise.

Cultural note: “Double down” can sound stubborn or defiant when a person refuses to reconsider a weak position. “Double duty” can be positive, but may also imply an unreasonable workload when applied to a person.
