The rest of the section includes more examples of Hasan attempting to do the right thing for other people but is thwarted by some other force. His efforts to warn Cairo of an impending invasion by a Turkish sultan go largely unheeded and the city is toppled anyways. As we have seen before, any moment of joy for Hasan is closely linked to that of sorrow or conflict. He finds a new wife and adopts her son as his own just as the situation of the sultan's invasion unfolds. After a stint in Mecca he ends up in Rome where he is baptized, given a new name(Leo Africanus) and taught of a new religion.
I found it interesting that one man can cover so much area through his travels. Hasan is everywhere. Whether he likes it or not, his experiences are forcing him to become a man of the world. What I did not fully understand was why Hasan was exiled so easily but sent out of town with a group of guards. In my mind, if you exiled someone in this time you would simply boot him out of your territory and not care what happens to him next.
