@Bl 4everr basically osiris stole seth seed so he couldn't have a baby which mean that nepthys went to him for help. He gave her his own seed and she pretended it was Seth's baby. In return, osiris was given a powder which contained the power of creation, so he raped Seth and trued to pit it in him so he could have a baby together. Seth trickef him out of it (thank g**) so Osiris ended uo in the underworld and couldn't return. Now he's using Anubis as a vessel after forcing him to awaken as a g**, which got rid of most of his memories, to take care of Seth's sins (the people who died while he ruled) so he can revive himself and ra** seth again. Right now Isis is relieving the memories of this becayse of Skhemet(the cat lady)'s curse on her. Anubis is trying to wake her up but saw some of the memories.
