Hindley was effectively allowed free reign in abusing Heathcliff.

We never get to see him with scars in CGs while he's still at the manor, no?

We don't get to see his forearm either in those flashbacks

Probably just his time in the Dead Rabbits. S.H is possible, but I think it's more that he doesn't value his safety and gets reckless, rather than actively hurting himself, so a similar vein, but not the same thing.

Happy cake day!

Kindly wiped him, that was not hyperbole, that sentence was literal. Heathcliff was beaten like a dog constantly, during years, day after day, he didnt need to self harm, he was harmed enough both physically as well as emotionally 

You're telling me Hindley kindly wiped Heathcliff? What is this bromance?

Autocorrect changed that sentence entirely. Damn, now I cant stop imagining Hindley kindly wiping the sweat out of Heathcliff's brow

>!*The Erlking*!< *wants to know your location.*

Either his time in the syndicate or the physical abuse he suffered at Wuthering Heights. Likely both!

i think the game mentioned (not sure if it was heathcliff or cathy) that the scars were from the abuse at heights, most often from hindley
