In Frankenstein, Walton appears as a similar character to Victor. Walton is ambitious. He rejected his family to become famous in the scientific field. Although his ambitions led him to loneliness, Walton can become a better person. That is why he met Victor, and that is why Victor shared his story.
Detailed answer:
Walton’s story appears in his letters to his sister Margaret. He describes his longing to make the world a better place. Walton desires scientific fame more than anything in the world. It foreshadows Victor’s story, showing profound likenesses between them. They are both ambitious at the beginning, which turns horrible for Victor.
When Walton’s people find Victor, the captain is surprised. The hungry and ill-looking person asks about the direction Walton’s ship is heading! When the stranger finds out that Walton’s ship is going toward discoveries, the initial surprise turns to interest. In the beginning, Victor is silent. It worries Walton, but soon he gets fond of the person he rescued and becomes rather protective of him.
His protectiveness turns into an intense attachment. On a subconscious level, Victor reminds Walton of himself. Walton forms a brotherly connection with Victor. The captain believes that this stranger is the only person in the world who understands him. It was even before Walton got to know Victor’s full life story. Later Walton recognized his ambitions in Victor’s narrative.
