Charles Dickens uses lightness and darkness to show change between the relationship of Lucie and Dr. Manette. “ ‘I want’... ‘ to let a little more light here. You can bear a little more light?’” (Dickens, 30). After this is said Lucie walks into the room, do you realize that Lucie is the light because she is hope. She is the only thing that can bring Dr. Manette back to his normal state or close to the way that he used to be. “... on her fairy young face, that it looked as though it had passed like a moving light,…” (Dickens, 32). This also ties back to me stating that Lucie was the light because Dickens makes a direct reference to her using a simile. These two quotes show how Lucie can help to change Dr. Manette and how she is some sign of hope, change, and a better future. Although dickens also shows darkness when talking about Dr. Manette going back to how he was in prison for 18 years. “… Like it once beautiful color faded away into a poor weeks stain” (Dickens, 30). These quotes from the book show us that Dr. Manette used to be this beautiful full of life person and now they use darkness and weakness to show what prison made him. “ darkness had fallen on him in its place” ( Dickens,32). In this quote the darkness falls upon him because he looks away from Lucie, it shows that he needs Lucie to help him get back to his normal state if he ever wants a chance of being better and that Lucie is the light for him and she is going to save him from this. Charles Dickens does a very great job of using lightness and darkness to explain the change that shall come in the future between Dr. Manette and Lucie.
