Late One night, years later, Alibaba snuck out of the palace to have a look at the slums. What he found there was nothing, no trace of junkyard street or people. As he was about to go back to the palace, he ran into Kassim. Alibaba was happy and felt nostalgic talking to Kassim after all those years. He went out to drink with Kassim and talk. While drinking, he noticed the level of respect Kassim had with all the adults, and how each were bowing to him. During the talk, Alibaba got drunk and told Kassim how he was able to escape from the castle. He ended up giving away a very important weakness of the palace. On the way back to the palace, Alibaba was trailed by someone Kassim had paid. After that, Alibaba went back to living in the palace.
