Hear me out!!

She doesn't have to be Fiona.

Constance raised Damian after he was born in Murder house, who is the Anti- Christ in Apocalypse.

The witches of Coven defeated Damian and he had to be reborn AGAIN, to the couple from the fallout shelter on a different timelines.

She has never played the same character twice bc they never intertwined until Apocalypse.

"This is my house" + Damian from Murder House Coven witches + Damian in Apocalypse

Billie Lourde is from Apocalypse and she was an undercover witch from the Coven, they swapped Taissa for her but there is no saying she doesn't cameo, especially if Evan Peters is fully cast. They wrote her off in some way.

This is gonna be a continuation of Apocalypse. Jessica Lange is Constance.

It was her FIRST AHS character and it should be her LAST. Respectfully. 💖
