Heathcliff - use of pronouns, the personal pronoun 'I' shows the raw emotion of Heathcliff as he confesses how he sought self betterment in order to make himself worthy for Catherine, so it would not 'degrade' her to marry him. Additionally, the direct address, 'you' creates a sense of personal explicitness, meaning Cathy cannot escape Heathcliff and her feelings for him. From this point guilt perhaps succumbs Cathy, resulting in her feelings of entrapment within the Grange and her marriage with Edgar. For the reader this is a moment of intense tragedy, as Heathcliff's efforts have ultimately been in vain, as Cathy has already married Edgar.
