The Great Pretender (from The Bitter Tears of Petra von Kant)

The very brilliant ending of "The Bitter Tears of Petra von Kant" (Fassbinder, 1972)
Petra (in bed here) has just, for the first time, asked her long-time masochistic faithful servant
Marlene to "Tell me about yourself." This is Marlene's reaction. (Note the pistol.)
