In this transitional chapter, Oliver is taken to an environment that is appropriate to the brightened aspect of his situation. Although the dismal events of his London experiences took place against a background of gloom, damp cold, and filth, he experiences this period of "true felicity" in a setting under brilliant sunlight and clear skies. Instead of the noisy tumult and oppressive crowding of the city, there is quiet calm and spaciousness. Harsh discords and foul odors have been replaced by gentle music and sweet fragrance of flowers.
Mr. Losberne's thoughtless barging into the house by the Chertsey Bridge illustrates that the tendency to act on impulse is one of the doctor's fundamental traits. Not content to let his character's nature be brought out by deeds and his own reflections, Dickens injects with more explanation.
The London journey is another example of how circumstances conspire to deprive Oliver of a chance to be completely vindicated in the eyes of his benefactors. A visit to the bookseller's stall would probably have yielded corroboration of a critical portion of his history.
