She's related to one of the four evil

I was thinking about this and I was wondering what if Ironside maybe had another kid but his memory was erased about that kind of like how his memories recently been erased about diodora

but that didn't make sense

so I'm thinking the green knight is possibly her father and he's forgotten her and she tried to live with a fake version of him for a while but she knew it wasn't real an

got sent to The cauldron and now she's trapped there and at some point she ran in the Tristan and found out who he really was and figured she could use her magic on him and that he could be of a help to get her out of there

And like with diodora she wants to figure out a way to get her father back and I think she'll actually get him back but in geodora's case I think that's not going to happen I think Ironside is still going to die either he's going to kill him do some reason or he'll be there witnessing Percival or Arthur kill him
