* The Captain's Loss: The captain recounts the loss of his entire crew to a monstrous polar bear. This tale resonates deeply with the creature because he understands the feeling of isolation and the pain of being ostracized. The creature, too, has experienced rejection and loneliness due to his monstrous appearance.
* The Captain's Fear: The captain's terrified reaction to the creature, even though the creature means him no harm, mirrors the fear and disgust that the creature faces from the rest of humanity. This further solidifies the creature's feelings of isolation and makes him realize his monstrous appearance will forever alienate him.
* The Captain's Narrative as a Mirror: The captain's story acts as a mirror, reflecting the creature's own struggles and anxieties. The creature sees himself in the captain's fear and isolation, and this further deepens his despair.
In essence, the captain's story doesn't make the creature upset directly. It's the story's themes of isolation, fear, and the consequences of one's actions that trigger a deep emotional response in the creature, ultimately driving him towards a path of despair and ultimately, revenge.
