Light vs dark Lucie Dr.Manette relationship

     Charles Dickens uses light and dark to set the tone of the relationship between Lucie and Mr.Manette in multiple ways. Dickens states," Darkness had fallen on him in its place. He looked at the two, less and less attentively, and his eyes in gloomy abstraction sought the ground and looked about him in the old way." This quote shows how he uses dark because that since he had never met his daughter due to his imprisonment, he didn't know who she was. He also says," He opened this, carefully, on his knee, and it contained a very little quantity of hair; not more than one or two long golden hairs, which he had, in some old day, wound off upon his finger." This quote shows light because  Dr. Manette compares the hair from his lock to Lucie's hair and he then realizes that she is his daughter. Lastly, Dickens states," Hailing his softened tone and manner, his daughter fell upon her knees before him, with her appealing hands upon his breast." This quote shows light, because when Dr. Manette finally realizes that Lucie is his daughter, they both get swept with emotions. Dr. Manette and Lucie's relationship is light and dark.
