Bastet has been trying her best to cockblock them after seeing the writing on the wall. Lions chase them towards a temple that used to be used for coming of age ceremonies for humans. Horus and Set get trapped in there. Bastet hears who she thinks is Osiris, offering to help her out. We don't see who she's talking to.
In the temple, Set hallucinates a woman that looks like Nepthys. She tries to entice him but he's only concerned about where Horus went. Meanwhile, Horus is trapped with Nepthys who is trying to guilt trip him but he only wants to get back to Seth and knows it's not really her.
I think both hallucinations were by Bastet? Also, Seth keeps smelling something that's familiar yet unfamiliar that's making him low key horny and it turns out it's Horus. He smells this when the Nepthys hallucination is with him and he gets a boner.
Can someone who read the raws explain how they got into that situation? I remember seth not reciprocating
