Oh god. This is the Lore section not the Embarrass Yourself section.
On the topic at hand, It's quite hard to come to a conclusion about the whole Word of the Mother thing. She obviously acted in desperation and didn't know the consequences, especially now everyone acts as if "our" Minfillia is dead. I think that there is something of her still left though, in the Antitower stuff, she switches between I and We, so I don't think she is 100% 'converted' but she's just playing the part to not give us hope that she can be saved.
And Theo mentioned the "lost and alone" bit. I really don't like that, because out of everyone Minfillia trusted her friends and had faith in them the most....Hydaelyn could still be a liar.
