On a visit to the count's house, the conversation turns to love (as it often does in this show.)
Maximilian is offended that aristocrats marry to preserve their fortunes and not for love.
Albert is so offended by this that they have a swordfight. The Count eggs them on.
The Count sows discord among he aristocracy. They don't really need help, what with the affairs and insider trading and all. A little nudge could bring the whole thing crashing down.
