He was completely isolated from the outside world for eighteen full years in the Bastille dungeon in 'One Hundred and Five, North Tower,' and during this time, he lost his memory, consciousness, and entire personality. During his prison years, to occupy his mind and not go completely insane, he took refuge in simple shoemaking, and his identity became trapped within this act. Years later, when he stepped out again on the roof of his former servant Defarge, his daughter Lucie and the banker Mr. Lorry found him. Under the intense love, compassion, and protective atmosphere of Lucie, he was brought back to London; he began to practice his brilliant intellect and doctoring profession again. Although he transformed into a normal gentleman, the 18 years of darkness and helplessness in his subconscious never faded; at the threshold of emotional trauma or very serious stress, he immediately slips into his old mechanical state, retreats to a corner, and starts tapping away at those shoes again. He is the purest indicator of how secrets and oppression can ruin human nature. In the final periods of his life, he is an honorable father and a disaster survivor, determined to erase all those black clouds in his mind with his daughter's compassionate hands.
