Aladdin uses his heat magic to give Alibaba some flames to power up Amon Sword. Alibaba runs and stab Kassim in the abdomen only to be swallowed up the black Djinn. Aladdin uses Solomon's Wisdom to ask Judal, and a flash of memories stream through Judal who collapses. Inside the black Djinn, Alibaba finds Kassim who states that he hated Alibaba ever since. Kassim wonders why they are so different and why he was destined to rot in darkness. At the same time, Aladdin holds off Judal's attacks on the outside. Kassim yells out that he will fight back fate, and Alibaba punches Kassim to snap him out. Alibaba states that he has done some wrong things, too. The two men starts attacking each other with their respective Rukh. With Alibaba down, he sees Kassim's memories of Mariam succumbing to illness and the slums burning down. Isnan approaches Kassim's group and tells them that he will assist them to fight their accursed fate. Kassim stabs Alibaba in the chest, and Alibaba's Rukh flows inside Kassim. He hears Alibaba's words, and he is touched by those words. Once Kassim sheds tears, the black Djinn begins to crack.
