The puppet show is a success, Itse's sister gets her new dress and Itse is accepted the newest knight of the Karmen roundtable.

Itse has second thoughts and tries to get the drum back, but the Pilots mock him for being concerned about a Roma girl. 'Why does he care what happens to her? Plus everyone knows that Roma's steal, so it will be her who is accused of the left not Itse.' Atije can't understand why her friend Itse is doing something to hurt her and decides that Itse is a thief at heart. Karmen threshes Atije to observe that Itse has the same need for acceptance as she does. Atije confronts Itse with a question: Does he prefer to stay in the gang or to remain her friend?

Jeylan claims it's a Turkish song so she has the right to perform it, and Violeta insists it's Macedonian and that she should sing it.

Jeylan understands that no one "owns" a song, and that she and Violeta can each sing the song their own way.
