yeh, imo cathy wouldnt have time for kids trying to kill her other selves(she cant mirror hop nor does she has the lust for revenge) so linton heathcliff would be made the same way hareton would. both still born out of nefarious reasons/treated poorly
i do think about that one part in c6 where hareton and catherine look over the graves but. i choose to make that unrelated to whatever the fuck erlking is doing
