I don't agree with this theory at all. Maeve's eyes weren't purple, that was a fae form she took on. I've read the entirety of both series and the only thing they have in common are the Faes.

Actually, Tillie's exact words were "you have to run, now." She didn't indicate later,she was dying and didn't have time to tell her all she thought she knew about Fatima s condition,so she summed it all up in "run, now" Fatima is changing into a monster. I'm so over Fatima and I think the change will do her good...kimono lady.
