Its a Bird Section 5

Contrast (writing):

In Section 5, you see Seagle become his own Superman. He realizes that he needs to mend his own relationships and save the day. His dad, however, does not try to mend the relationship between he and his sons. His dad wishes he never had kids because of Huntingtons disease running in his family. Seagle tries to comfort his dad in telling him that he would rather live his life and then be diagnosised with Huntingtons rather than not living at all.

Contrast (Visual):

After Seagle becomes his own Superman and mends his relationships. He becomes a happier person. On page 123, you are shown Lisa and Steven in their home, with walls painted bright Yellow and sun coming through the windows. Unlike the rest of the novel, this page is bright and full of color. Seagle is a happier person because of the mended relationships of his family and his girlfriend. He sees a brighter outcome in his future and is no longer living with a fear of Huntingtons.

Fate VS. Free Will:

At the beginning of the book, you can say that Seagle thinks of himself as fated. He has the constant fear of Huntingtons disease and tells Lisa that he does not want to have kids. He became his dad after overhearing that he wished he never had children. Seagle does want to bring children into the world if it means there is a chance of them being diagnosed. In Section 5, you see Seagle make his own choices  and decided that maybe he will want to have kids. He also decides to take on the Superman job because he realizes that he and Superman are alike.
