Stephon is writing an essay that compares and contrasts the way in which characters from two different texts face obstacles in their lives. The two characters he is comparing and contrasting are Manjiro from Heart of a Samurai and William, the narrator of The Boy Who Harnessed the Wind. One similarity he notes is that Manjiro and William are both courageous.
