I'm afraid not - not got a 360, you see. I chose the Dark side over the Green side and got a PS3.

But I've got friends who've played Lost Odyssey, so I know a bit from them.

If you've finished the 3rd disc (or near enough), then this is what I saw at a friends house:

It started with Kaim and Sarah hijacking a train and having to fight off another bigger train. From there it was to a custscene inside another train, with a couple of monarchs and the rest of the party talking and eating. Then Gongora, the card that he is, sent out some kind of freezing spell and froze everything (you also play as Gongora for a moment, and shoot ludicrously over-powered spells at his loyal followers, until one defies him and is killed for real). Yada yada, Kaim and Sarah on a freezing train, get to two kids at the front, Sarah cuts off the back half of the front carriage, to which the rest of the train is connected, and the half with Kaim and Sarah in it crashes into a giant ice boulder thing. And that was that.
