Heart of Darkness: Chapter 3 end

Marlow returns to Brussels sick, and his aunt brings him back to better health.  He also brings back a book about savages and with that he brings back a whole new perspective that probably no one around him will ever experience.  He sees everyone and there over privileged lives and thinks of them as snub and not understanding of the other "world".  As Marlow returns and stays with his aunt, she praises Kurtz and even though Marlow doesn't want to hear it, he understands that he is one of her only people around her and like that ironically the story ends, into The Heart of Darkness.
