Here, readers learn about one more thing that Darius and Dad have in common: diagnosed depression, which they take medication to manage. But while Darius doesn’t say much about his own thoughts about his diagnosis, note that he’s pretty convinced Dad is ashamed of himself and of Darius. It’s not entirely clear where Darius gets this, as Dad doesn’t seem to be trying to hide his depression from Darius or make Darius feel bad for having depression and taking medication. So, this may reflect Darius’s beliefs about mental illness rather than Dad’s.
