no no, he was definitely being manipulated lol. he had no inclination to rape seth from the get-go. both of them had sex against their wills.
(spoiler below)
that's why when horus snaps out of it, he's crushed and can't comprehend what he'd just done to seth. sekhmet successfully messed with both of their minds.
(i think @Syxx should be able to give you a more in depth response about this).
Ohhh omg ok that makes more sense, coz i though it was so out of character for horus to do that sort of thing man. Thanks for the info :)
Don't worry you'll see soon in a few chapters
wait I really like horus but why did he go all the way with seth? I was willing to forgive him coz I thought he was being manipulated or something but from what little I understood he was not, so like he willingly raped seth??? Dude that scene is so hard to read and osiris triggers me so fucking much :/
