The most important part of the story is when Fox betrays Magpie and leaves her alone in the desert. This is important because it shows how Fox is a selfish and cruel character who only cares about his own needs and desires. He does not value the friendship and trust that Magpie and Dog have built together. He also does not respect the differences and disabilities of others. He manipulates Magpie by making her feel insecure about her burnt wing and tempting her with the promise of flying again. He also tries to make Dog feel jealous and lonely by telling him that Magpie does not need him anymore. He uses his words and his appearance to deceive and hurt others. This part of the story reveals that Fox is a symbol of evil and destruction in the burnt forest.
