Question Why is horus seeing Seth wife if it suppose to be someone he likes? Thanks

I wondered this, too. He said "You're not here for me. You're here for Uncle Seth. You want to expose him. Is Osiris the one you serve?" and then that illusion Nephthys lunges to attack him, looking like a cat. In the chapter before this, Osiris offers to help Bastet, and tells her a method only she can do. I assumed it had something to do with Bastet, because of the catlike appearance when the fake Nephthys attacked Horus. But, I wonder what he meant by exposing Seth? Like exposing what Seth was up to with Horus? The woman Seth was with warns Seth to be wary of the Sun God's daughters because one of them (Hathor) desires Horus. Maybe they have power over what appears in the temple, and Bastet was using that with the help of Osiris to split them up or something??? Idk we'll have to see if their plan gets explained in later chapters lol

damn sorry for this long ass response also
