Quote context

[...]

- You were kidnapped by wicked sailors and brought to England.

- Don't make fun of me, Cathy.

- I'm not making fun of you. You're a really and truly Prince. And I'm your slave.

- You're not my slave. You're my queen, Cathy, and you'll always be my queen. Nobody else will make you his queen, you hear?

- Yes... your queen.

- And that's the way they grew up. Wild and free, roaming the moors together.

- But Hindley grew more and more jealous.

- Cathy was eighteen and Hindley past twenty-one when Mr. Earnshaw died.

- Good man, he never saw the evil of life and had raised Heathcliff like his own son. But on the very day of his funeral...

- You're not going into that room to look at my father's body.

- Why? He loved me more than he did you.

- He's past your wheedling now. I'm master of Wuthering Heights.
