Magi - Season 1 Episode 8 A Broken Promise

Alibaba pass through Aladdin, claiming that unfortunately he can't keep the promise he made to him and invokes the flames of Amon's sword to escape with the rest of the Fog Troupe. Back to his room, Alibaba is kidnapped by Morgiana who brings him before Aladdin so he can explain himself properly. Meanwhile, Sinbad discovers that Balbadd is being pressured by the Kou Empire to adopt their currency. Alibaba reveals to Aladdin and Morgiana the story of how he was raised in the slums along Kassim, the de facto leader of the Fog Troupe and after his mother's death, he was taken in by his father, the King of Balbadd. On his deathbed, the King recognized Alibaba's capacity and asked him to assume Balbadd's throne, but while considering his offer, Alibaba sneaked out of the castle and met Cassim who made use of the tunnels used by Alibaba to infiltrate it with his fellow bandits, much to his regret.
