Noooo dont buy osirishit's word. He himself isnt making any sense rn. One moment he says he n seth go back and next moment he said "u said u weren't into men and rejected me" which is completely contradicting his earlier statements. The amount of brainwashing and extreme psychological manipulation this bitchass is capable of is immeasurable. Also the taboo he broke by chasing their past memories is bound to come back with insanity whiplash. Whatevr he's ranting rn might very well be a case of false narrative.
Im also taking into consideration the infinite void cave chapter where the hieroglyphics in feathers translate to cryptic clues abt their past lives. There were mentions abt an elder brother who didn't like wars n preferred studies. An elder brother who was always followed around by his younger brother and who taught this younger brother snd started finding him adorable and stopped finding him irritating. U could interpret this as osiseth but we also cannot rule out the possibility of osiris falling one sidedly in love with seth in their past lives. Some interpret this mural as horuseth but it kinda feels more osiris n seth situation to me. For now we can only theorise n hold on( ̄∇ ̄")
Yup n who's to say that wasn't one of the main driving points for him to orchestra HTE's murder. I also believe there are more taboos existing apart from the dont chase past life memory taboo and dont make big future prediction taboo. In the hte death mentioning mural its said "they should not break taboo until they become gods" i wonder what is this referring to.....

So he rejected him before he lost his memories? Or after? Was Seth ever in love with him? I dont buy it.
Is it the same thing happening again? But Horus didnt forget him??!!!!
