Had the same upbringing - nice to begin with, but treated as a servant once people die
"[Hareton] lives in his own house as a servant" - Nelly
When Nelly leaves WH to go to TG, Hareton turns from a polite young man to a little savage, much like younger Catherine and Heathcliff
Hareton - abuse
Heathcliff intends, and even tells us that he will turn Hareton into his servant
"Now my bonny lad, you are mine!"
But ultimately, Hareton doesn't grow as crooked as Heathcliff - he marries Cathy and at the end of the novel, is on the verge of having a very nice life - he's able to break the cycle of revenge, not become bitter, and have a happy ending
Hareton - happy ending?
Heathcliff is capable of showing love and affections, and fails to do to Hareton what's been done to him
"Mr Heathcliff, I believe, has not treated him physically ill" - Nelly
Heathcliff himself says that he strugglestohate Hareton the same way Hindley hated himself
"I'd have loved the lad has he been someone else" - Heathcliff
Hareton's reaction to Heathcliff's death indicates some level of care and affected between the two
"[Hareton] sat by the corpse all night, weeping in witter earnest"
Hareton sees Heathcliff as somewhat of a father figure to him
Hareton - connection with Catherine
Heathcliff sees Catherine in Hareton more than in Cathy:
In the world of Wuthering Heights, biologydoesn't really matter, people's spiritsmattermore - Hareton reminds H of C because he has the same ruggedroughness that C had when she was a child
Cathy, however, is the product of TG, and so H sees her just as Edgar as civilisation - the things that Heathcliff and what he represents is against.
In a way, Hareton is almost like a replacement of C for H - unlike C, Hareton stays with H at WH
Hareton is what H and C could have been
Cathy - comparison to her mother
Doesn't resemble C much
"That capacity for intense attachment reminded me of her mother: still she did not resemble her; for she could be soft and mild as a dove" - Nelly
Cathy is more a product of the civilised world of TG
She's also unlike C in the way in which she was her fathers favourite - which accountsforhersoftness that her mother didn't have.
Cathy - sheltered upbringing

"till she reached the age of thirteen, she has not once been beyond the range of the park herself"
Edgar tries to remove the connection of her mother's upbringing, therefore she's naive at times - she mirrors the developmentofIandE.
Cathy enters the world of WH and has to try and survive
But unlike I, who runs from the world of WH, and E who simply presents that it doesn't exist, Cathy is able to confront it.
Naivety
Cathy is unable to see the dark side of Linton
She is manipulated by Heathcliff and marries him
This marriage ultimately breaks down her naivety
Cathy - deception from appearance
Cathy's deception from appearance is an improvement from her father
He was initially deceived by Hareton's rough appearance, thinking that he is the same as Heathcliff
She eventually sees under his appearance
Cathy is an example of civilisationembracingnature
Cathy is also an example of what Edgar and Isabella could've been, had they been more compassionate and understanding.
