In coven Fiona couldn't give her soul to Papa Legba since she didnt have one.
but was it ever told why she doesn't have one? Did Ryan speak on it?

did they ever explain why she was in Papa Legbas hell too.

She killed people..

Not sure. They also never explained all the other witches powers they had that the others didn't

i assume she promised it to the axeman ? thats why he got to spend all of eternity with her ? only thing that makes sense imo.

nnnnnnnn, NOT you asking about a plot hole in Coven when there are like 100.

They had said in times when the coven is in trouble they all become powerful.

No sis that was hell

Fiona's story (infact, the whole Coven story) was a bit jumbled. I felt like there's gaps that should have been filled but were sadly left empty.

She was in Axeman's paradise

She promised it to Axeman, that's why she couldn't bargain with Legba.

Myrtle also said that since Cordelia wasn't using her powers, they were manifesting in the witches around her.

Which episode?

I wasn't under the impression that Papa was sovereign in the underworld. I will always assume it is Lucifer (with eternal flames) unless stated otherwise. If she doesn't have a soul she shouldn't have been in any kind of hell anyway... yet she was in Papa Legbas hell .

yeah but she told him she would be with him forever didn't she ? maybe she sold it and she didn't know

The murderous v and the human voodoo doll powers?

I'm pretty sure it had to do with the fact that she told him that she would kill her daughter/Cordelia if he made her immortal.

Rewatching the season. I'm seeing all the subtle hints. The beginning where they said Kyle was on the bus and Nan looked up. When Cordelia was splashed with acid the next day Fiona was looking.. Younger..
