A defeated Schön resigns himself to marrying Lulu. While the wedding reception is underway, he is disgusted to find Lulu playfully cavorting with Schigolch and Quast in the bedchamber. He gets his pistol and threatens to shoot the interlopers, but Lulu cries out not to, that Schigolch is her father. Schigolch and Quast thus escape. Once they are alone, Schön insists his new wife take the gun and shoot herself. When Lulu refuses, the gun goes off in the ensuing struggle, and Schön is killed.
