Certainly, the reunion scene between Dr. Manette and Lucie has a sentimental quality to it; Dickens plays up the emotional side of the scene in Lucie's reaction to seeing her long-lost father:
"With the tears streaming down her face, she put her two hands to her lips, and kissed them to him; then clasped them on her breast, as if she laid his ruined head there" (Book 1, ch. 6).
Lucie's tender reaction to her father's ruined state brings a decidedly sentimental and emotional quality to the scene; when Mr. Lorry is more than a little perturbed at Dr. Manette's struggle to recall his past life, Lucie uses a gentle approach and kindness to help her father understand her connection to him. She speaks to him softly and gathers him in her arms. Dickens characterizes Manette's reaction to her comfort as being extremely childlike. Dr. Manette's weakened and confused mental state has resulted in their reunion being bittersweet, but it is Lucie's adept handling of the situation that helps the doctor slowly begin the process of being "recalled to life."
