 Studying Dr. Jekyll, Mr. Hyde? Let's look at key quotations to remember for the character of Dr. Jekyll. He's described as a large, well-made, smooth-faced man of 50. These adjectives emphasise his upper-class position as a Victorian gentleman. The word large also contrasts how small Hyde is, tying in to how Hyde is presented as an ape-like. Secondly, when Otterson speaks to him, there came a blackness about his eyes. The word blackness conveys dark imagery, and this links to the theme of duality, the dual nature of man. Otterson is talking about something he wants to keep secret, and hence we can now see his real nature emerge. When Hyde kills Sir Denver's crew, Dr. Jekyll says, I swear to God I will never set eyes on him again. I swear to God is religious language, and this ties into the theme of science and religion. Dr. Jekyll's punishment came as a result of him misusing science to create Hyde, and now he's promising that he will never set eyes on him. Never set eyes as hyperbole, showing his extreme shock at Hyde's actions.
