Why Did the Students Have to Die
A living ship that is closely related to a shrimp? Check.
A group of students from around the galaxy that are exceptional at Math, Science, etc.? Check.
the inclusion of the Meduse attack serves a purpose in the story. The attack is necessary because it represents the reality of the world. The interactions between the students were truly pure, and the students were creating bonds with people who society would normally separate them from. The environment that is fostered on the Third ship would not work in society, so it seems that Okorafor is showing how the innocent interactions can easily be burnt out by external influences. Everyone had to die to show the harsh reality of society, and the problem that begins to emerge when people begin to learn and understand about one another. Society needs people to rely on stereotypes because it helps them create categories that keep cultures separated from one another. The students on the Third Fish are causing a disruption to this norm, so they cannot be allowed to survive in the world.
