The line "We are fighting with the Harkkonen's" is a bit muddled. They are fighting along side the Harkkonen's? Against them? They aren't escaping with Shawshank or blowing up with the death star.

Although in the original work, the ruling Harkkonen's over indulged in food, wine, and super creepy, gay rape and because of this were disease ridden and fat because of it, so maybe they are admitting more than they care to....
