From his introduction to the novella, Fred generates a positive atmosphere which affects both Scrooge and tone of narration. This is first highlighted when he enters Scrooge's counting-house in Stave One. Prior to his arrival Dickens focuses on cold, gloomy imagery. When Fred appears at the door, however, he "heated himself" and looked to be in "a glow", introducing warmth to the stave. This is significant as Dickens previously asserted that even "external heat and cold had little influence on Scrooge" which suggests that Fred's virtue is stronger than the forces of nature. This may perhaps spotlight the power and value of family.
