The two new friends established themselves in the house during his absence; where I heard Hareton sternly check his cousin, on her offering a revelation of her father-in-law’s conduct to his father. He said he wouldn’t suffer a word to be uttered in his disparagement: if he were the devil, it didn’t signify; he would stand by him; and he’d rather she would abuse himself, as she used to, than begin on Mr. Heathcliff. Catherine was waxing cross at this; but he found means to make her hold her tongue, by asking how she would like _him_ to speak ill of her father? Then she comprehended that Earnshaw took the master’s reputation home to himself; and was attached by ties stronger than reason could break—chains, forged by habit, which it would be cruel to attempt to loosen. She showed a good heart, thenceforth, in avoiding both complaints and expressions of antipathy concerning Heathcliff; and confessed to me her sorrow that she had endeavoured to raise a bad spirit between him and Hareton: indeed, I don’t believe she has ever breathed a syllable, in the latter’s hearing, against her oppressor since.
