In this episode, Gon becomes very sad.
And then the situation gets very serious.
I write a fair amount about depression, which is a topic many people have first-hand experience with.
(How many people in the developed world are taking anti-depressants? Lots.)
Normally, people with deep, persistent depression don’t snap into manic action. Many cases of depression involve a sense that there is not enough energy to do anything.
In some cases, however, people who become depressed suddenly might behave as energetically as Gon does in this episode.
I won’t spoil it. It’s worth your time to watch the whole thing.
