In the novel 'Wuthering Heights' by Emily Bronte, the main trait of the character called Lockwood is curiosity. Of course, being the speaker or narrator, he represents us - the readers - with this trait. The reason for the author's presenting of him as being curious, is that she wants us to be curious enough to finish reading the story to see what happens/happened. Emily Bronte succeeds in this ambition with very many readers - Lockwood's curiosity is our curiosity and we find the novel compelling and gripping. He questions Nellie Dean on our behalf, and finds out the things we all want to know and would probably ask if we were there. However, 'curiosity killed the cat, and information made him fat' - and what he hears is a not very pleasant stroy!
Heathcliff's dominant trait was his drive for vengeance. He used this drive to ruin Hindley's life, his wife's life, Edgar's life, and his own son's life. Yet, in contradiction was his devotion and desperate need to have his beloved Catherine.
Lockwood is the tenant. I think he is somewhat timid. He gets stuck at Wuthering Heights fattier the storm and has to stay over night. He has to face Catherine's spirit and becomes embroiled in the mystery.
Hareton is Hindley's son whom has anger and is uneducated. Heathcliff has raised him to be somewhat like him. He is moody and distant. However, he contradicts this trait when he begins to feel affection for the daughter of Catherine and Edgar.
Mrs. Heathcliff was once madly in love with Heathcliff. She was elegant and well-bred. She has been reduced to nothing more than a servant in her home with Heathcliff and is bitter.
