In 2012 We Have Texting, in 1790's, There Were Milkmen: Wuthering Heights Journal: Part Seven

So Heathcliff plays matchmaker, and it's kind of creepy.

So a few years have passed, and Catherine II sneaks up to Wuthering Heights yet again... and this time she runs into Heathcliff. He invites her in, and there Heathcliff tells Ellen of his master plan. The plan is this: have Catherine II marry Linton (who, if you remember, he stole...) and when Edgar dies and Linton eventually dies (He's kind of sickly) Heathcliff inherits the Grange.

Ellen realizes how bizarre this whole thing is, but by this point, Catherine II is already infatuated with Linton and the other companion, Hareton. Ellen attempts to explain to Catherine II that this is a horrific mistake, and Heathcliff is, quite plainly, evil.

Heathcliff is prompted to explain that he and Edgar (her father) had fought that Heathcliff was not good enough for "Aunt Isabella". He conveniently leaves out the part that he was the last to see Catherine I alive and conscious, and very well could have been the reason she passed away.

So they part, and Catherine II wants to go back (eventually). She tells her father about this (and Ellen kind of gives her side) and Edgar forbade her from ever going to Wuthering Heights and ever seeing Linton again. She throws a hissy fit, but being it her father forbidding her, she quickly recovers and runs away.

She keeps in contact with Linton through various love letters. This process is worthy of explaining how exactly it goes on:

So there's a milkman who appears every morning who usually wears a coat. She'll meet him when he drops off the milk. She swaps a piece of paper in his pocket for one of her own. The paper contains a letter responding to Linton's, whose letter she just received.

Ellen being the made-of-awesome servant she is, picks up on this rather quickly, and discovers her stash of these letters, and threatens to go to her father with this. She says that Ellen should burn them instead, and that satisfies her on the promise that the letters will stop.

There is a lot of drama there, but all that becomes of it is a much gloomier Catherine II.

Okay: Reality Check time! Say she marries him... She's marrying HER OWN COUSIN. Do either of them realize this? Is there not some moral issue here? Where's Joseph when you need him?

Anyway, I predict that Catherine II and Linton end up together despite this whole mellow-drama. Heathcliff, I think is getting his payback for being evil through having to live such a long miserable life... I gather. And again, I am waiting for Mr. Lockwood to act as something---anything---more that just a narrator/vessel by which this story is told.
