What evidence is there that Dr. Manette is greatly disturbed by the prospect of Darnay's and Lucie's marriage?
When Charles Darnay confesses his love for Lucie to Doctor Alexandre Manette, he tries to disclose the secrets about his identity. But Dr. Manette stops him at that time and insists he tell him that on their wedding day if things proceed successfully. As promised, Darnay reveals his true identity and real name to Dr. Manette in the morning of his wedding with his daughter Lucie Manette. He discloses that he is actually a French aristocrat, a descendent of Evrémonde. Darnay’s ancestry was known for known for their oppressive behaviour and notoriety. Dr. Manette had been imprisoned in Bastille for several years because of Marquis St. Evrémonde, Charles Darnay’s uncle. He had denounced Darnay’s family “and their descendants, to the last of their race”. We notice that Dr. Manette anyway had some suspicion about Charles Darnay. After the discussion with Darnay on the wedding morning, however, Dr. Manette grows “deadly pale” as there is no room left for doubt now.
He was so deadly pale—which had not been the case when they went in together—that no vestige of colour was to be seen in his face.
Although Mannette blesses both of them, he is not comfortable about his daughter’s marriage to Darnay. He doesn’t have the strength to bear the truth about Darnay. He loves his daughter very much and does not want Darnay’s ancestry come in between her love and happiness, and this is why he keeps this thing to himself. Although Darnay tells him that he had renounced his French nobility and convinces him of his good intentions, Dr. Manette struggles with the reception of his identity. Darnay’s confessions surface his deeply buried emotions. His inner struggle and conflict make him disturbed and upset at the wedding. Mr. Lorry noticed that something was wrong with his expressions.
But, it was the old scared lost look that troubled Mr. Lorry; and through his absent manner of clasping his head and drearily wandering away into his own room when they got up-stairs
Later, Manette silenty retreats to shoemaking. This serves as another evidence that he was not feeling quite right. During his imprisonment, Manette used to indulge in shoemaking that would keep him away from the torment and tortures of the prison. He was doing that now to distract himself from his inner struggle and suffering.
The bench was turned towards the light, as it had been when he had seen the shoemaker at his work before, and his head was bent down, and he was very busy.
