I don't know if it helps, but I've kinda already got Jason's story planned out in my head...

Also about the army...one of the little scenes I've got playing in my head is Jason's mind being "awoken". He is taken by an oracle guy, they (the little quest group) meet earlier on, who is with the army fighting etc. Anywho, he takes Jason to his tent, and awakes his mind, which triggersoff Jason's "war machine" ability, causing him to wipe out the whole army camped there...the magic spreads over a 5 or so mile radius, nearly killing the rest of the hroup, who only escape it by goign underwater...anywho, I associate this scene with the end of the game, and the last thing is that the group goes back and finds Jason in a very very big crater left by his destrcutive magic, and they have to fight him, and maybe, I don't have a clue if it will be allowed or not, end up killing him...and the game ending in a cutscene where Jason finds control of his powers etc, and comes to his senses long enough for a tearjerking scene with Emilia crying over him, before finally dieing...

I've just noticed, I type too much...
