So I have a theory. When ever we've seen a glimps of Tia's mother she is clearly dressed well. I have an interesting theory that she's run away royality from another country and either she actually died or was forced to return home and then died and Tia's Father can't talk about it at all. I mean why the hell would he not talk about Tia's mother to her ever?! Because if he tells her anything she might figure it out and put her in even more danger.
