Interesting. Never really thought of this before. Always wondered about that line and never really came up with a satisfactory answer to it.
I agree with you completely....I think that it may have been in fact Schala who was saying that to Serge.
Why? Why would she say something like that to him? Maybe because of the fact that she has been waiting on him for 13,020ish years, perhaps?
I mean, wouldn't you feel that way about waiting that ridiculous amount of time for someone who had the power to save you from eternal damnation?
Additionally, how would FATE be able to communicate even, with Serge at that precise moment? Sure, it destroyed the Dead Sea along with the Frozen Flame, but does that imply communication with him? On the other hand, Schala had every opportunity to do so, through the Frozen Flame, which supposedly resided somewhere in that place.
