* Initial Denial: Jekyll initially denies any knowledge of Hyde, claiming he's never heard of the man. This is a clear lie, as we know he's intimately connected to Hyde.
* Defensive and Evasive: He becomes defensive, accusing Utterson of trying to pry into his personal life. He even goes so far as to say, "This is the end of it. I beg you to let me be."
* Shifting the Focus: Jekyll tries to deflect Utterson's concern by focusing on his own reputation and asking Utterson to trust his judgment. He insists he's capable of taking care of himself.
* Uneasy Promise: He makes a vague promise to reveal the truth about Hyde, but only if Utterson will let him live his life in peace.
In short, Jekyll's response is characterized by:
* Deception: He clearly lies about his relationship to Hyde.
* Anxiety: He appears incredibly uneasy when confronted about Hyde.
* Control: He tries to regain control of the situation by silencing Utterson and directing the conversation.
It's important to note: This is a crucial moment in the story, as it foreshadows the eventual unraveling of Jekyll's secret and the true nature of his relationship with Hyde.
