Okay but huuge spoiler alert!
Basically horuseth are having lovey dovey time in the bath and that fuckass mirror shows up, lot of talking, I was too lazy to translate that, but in the end, Seth believes that the real Nepthys (not only her feelings) is locked in the mirror. He also found out that the mirror can swap your romantic feelings, and that Horus have looked into the mirror. So he now thinks that Horus's love for him is fake, and tbh, how can Horus defend himself in this situation? The fight then escalates and Horus destroys the mirror, and Seth sees that as killing Nepthys, (because again, he thought that her entire person is in that mirror, which is not true)
and so he goes of and gouges Horus's eyes out. And yes you read that right. Both of his eyes. And then he storms out, being followed by Fg. In the next chapter tho, Horus gets one eye from Thot and Seth seems just distorted.
Yeaa that kinda summarized the last few chapters. And I love ur username bbg, it's so fr (=・ω・=)

Horuseth nation enjoy these moments while they last we are about to shattered
WE HAVE TO STICK TOGETHER THROUGH THIS (╥﹏╥)
