Tbh I think Isis knows that the mirror is used for making someone fall in love with you or at least doing something to their memories. Sekhmet revealed it to her during that coma/dream thing that she was in earlier, you can tell because Isis's hair is short when she is watching Seth and Nephthys with the mirror, but Isis's hair used to be long naturally. So she figured out that Osiris wanted to do something to Seth with the mirror from Sekhmet, and she likely figured out the love part due to the fact that Hathor gave Horus that same mirror and she was trying to marry him, so now Isis wanted to use the mirror to replace Anubis' "love" or obsession with Seth for someone or something else, but she doesn't know how to activate the mirror. The Sekhmet on the mirror's mouth opens when (I assume) she's using it for something, but I don't know what happens when Hathor uses it. (If she ever does anything with it in s1 other than just holding it, please let me know, I haven't read season 1 in forever and I lowkey don't want to.
oh my gosh WHY THE HELL AM I YAPPING RN...? This long ass paragraph aint nobody reading ts anyways yuh this is just my thoughts

I think this is what Isis was made to see in all that time she was unconscious. IIRC, it was Sekhmet who'd first made her fall unconscious like that, after offering a wager... that if Sekhmet won the bet by showing Isis something that DID manage to convince her that things hadn't happened the way Isis thought they had, then Isis would be forced to grant Sekhmet a favor.

Haha I'm reading your long essay
I haven't read this for years because I'm waiting for it to be completed. I took a peek today and boy wth it's still ongoing. I stopped reading when Seth was sent to the human world as punishment around after Anubis "died" or something if I recall correctly. I let it marinate and WHY IS IT STILL ONGOING?!? will this be a 200-400 chapter type of webtoon?
how long did Isis know the truth????
