The relationship between Scrooge and Marley is the only relationship of Marley's that the reader is made aware of. Dickens writes that "Scrooge was his sole executor, his sole administrator, his sole assign, his sole residuary legatee, his sole friend, and sole mourner". The repetition of "sole" highlights Marley's isolation and dependence on Scrooge, while the possessive pronoun "his" illustrates how Marley was equally as important to Scrooge. This emphasises how vital their companionship was to each other. Dickens may be trying to portray the idea that even miserly old men like Scrooge need companionship in life. Despite the fact that their relationships may be perceived as dysfunctional, Scrooge was never completely alone until after Marley's death. It is possible that Dickens intended to show the reader that relationships are crucial. The lack of companionship in lives of Scrooge and Marley caused their bitter attitudes.
