Wanda calls Brent a "quisling", a traitor. In 1933, as the Nazi party was taking over Germany, the Norwegian politician Vidkun Quisling established a fascist party in Norway. After the Nazis invaded Norway in 1940 Quisling headed the puppet government that collaborated with the Nazis. This 'Quisling Regime" assisted in the genocidal 'Final Solution'. After the war Quisling was convicted on charges of treason and genocide and then executed. For decades afterward "quisling" was the worst insult you could use against a politician.
Ironically, The guest star, Hockey team Ducks, Travis Moen, was featured in an episode where one story-line followed a series of plumbing problems (Moen is a very large plumbing fixture manufacturer).
