Taken from the Lost Odyssey TGS 07 Developer Walkthrough (available on Gametrailers.com), we see Seth (a woman immortal) searching for her son amongst some prisoners.
Btw, although it sounds like her son is also called Seth, her name is officially Seth on Mistwalker's website. It may be changed in the final English version.
Also, all lip-synch is done to the English voices, and not the Japanese voices, hence why the voice-acting and facial animation is so good. The game will be dual audio, but for once, I might actually go for the English version!
If there was ever a reason to get Lost Odyssey, THIS IS IT!
