The narrator ruminates on his grandfather's advice, deciding that overcoming people by being the yes-man didn't seem to work—unless his grandfather meant the principle and not the people.
The narrator realizes that the "world is possibility," just like the vet told him, and that's why people like Rinehart can exist in multiple roles.
He recalls seeing Mr. Norton at a subway stop. Older but dapper, Mr. Norton was lost and didn't seem to know who to turn to for help.

The narrator explains that writing his story down is helpful. He claims that hating must come with loving, and that he sees the importance of humanity as his grandfather had. The narrator decides that his hibernation has gone on for too long and says he will shed his skin and leave his hole.
The narrator concludes by suggesting that he not only wrote the book to let people see past his invisibility, but also to hopefully speak for people with a similar plight. His last line is: "Who knows but that, on the lower frequencies, I speak for you?"
