1. she was in love with osiris and so she felt guilty to seth cause she cheated on him. this caused seth to be the person he is now and so nephthys feels it is partly her fault that egypt and its inhabitants suffered
2. love takes on different forms. personally i believe osiris did love seth. i mean I'm pretty sure seth was one hell of a god before he found out his brother banged his wife. but his feelings became too dangerous when he couldn't be satisfied with their "brotherly relationship". so yeah, osiris loved seth. but it was a very toxic and selfish love that only benefited him
3. anubis is osiris's son. cause, yeah, osiris slept with nephthys who is seth's wife
4. osiris was killed by seth so he became the god of the underworld. we saw in the first chapters that he appeared in the land of the living but that was because osiris was able to possess his son - anubis - and use his body to temporarily be in the land of the living. but he's supposed to stay in the underworld

3) oh but if he is dead, why does he have a heart when its on the scale of judgement? This was pointed out by Ra but nobody listened to her because of Isis's interuptions. I personally don't think he is dead only his physical form is decayed and still alive (spiritually).
But if his physical form is dead, then he wouldn't have a physical heart (i think its Anubis's) and that is why Maat's scale didn't tilt. Because its not his heart. And still, Osiris still took precautions and tell only half the truth of what had happened.
I think it will be discussed a bit more in the 2nd season so I'll be waiting.

She didn't cheat Seth, Osiris implanted his semen in her artificially. Seth knows that his wife and Osiris didn't have sex, so he is not mad. The reason why set is so angry, is because Osiris raped him for 10 hours by threatening him that he would kill his son, if he doesn't have sex with him. He loses his mind, when he remembers of him begin raped, or for all the bad things that Osiris has done and tell him.

and like i said that doesnt make her actions any less than cheating. "did this for her husband" - did she expect seth to thank her for getting herself pregnant by another guy or something?? she still damn cheated. and whats worse she has feelings for osiris so I'm pretty sure there was some personal interest with the shit she pulled
Yall I am mad slow so can someone explain to me
1)did Seth's wife and brother have sex with each other if so why did the wife look like she was in distress(or rid he r*pe he?)
2)was the broth actually in love with Seth or was it more like "your my possession so nobody can have you only me"
3) is Anubis not Seths son or what
4)is the brother alive or did he die if so whats with the beginning chapters
