How does the main character change or evolve throughout the course of the story?

           The big change in the story was when Eddie finally let go of all the anger he had built up towards his father. His father was a also a worker at Ruby Pier, and he often came home drunk and very angry from his day job. Eddie's father acted out abusively towards Eddie when he was a boy, which caused Eddie to hate his father for ruining his childhood. While Eddie is in the mountain range and meets Ruby, she tells him a story about his father, which causes Eddie to change his views on his father drastically. Ruby says to Eddie:

"Learn this from me. Holding anger is a poison. It eats you from inside. We think that hating is a weapon that attacks the person who harmed us. But hatred is a curved blade. And the harm we do, we do it ourselves."

Ruby continues telling Eddie that he need to forgive his father, and reminds him of the lightness that he felt when he first arrived in heaven. Eddie questioned her saying asking where his pain is, and she continues by saying:

"That's because on one is born with anger. And when we die, the soul is freed of it. But now, here, in order to move on, you must understand why you felt what you did, and you no longer need to feel it."

This is when Eddie finally let go of his anger and realized, he was finally set free as he forgave his father after years and years of hatred towards him. Forgiving him was hard, but Ruby let Eddie know that forgiveness was needed to be done in order to move onto the next Heaven.
