he has more than one son? what the fuc

Yeah Anubis

Anubis is also Osiris'. Neph cheated on Seth who's infertile, but Neph was under the control of a mirror gifted to her by Osiris who made her forget she loved Seth. (My understanding of all that we've covered so far)

So Osiris' sons are Horus and Anubis, and all three of them are obsessed with Seth.

oh yeah Anubis, I forgot and panicked there I thought he had another son (not Anubis)
