If the thread is talking about the ending, it's a pretty sure bet they're giving something away.

There's nothing extra, just a CG movie at the end which can be downloaded off the internet I'm sure. It just consists of some very pretty scenes set in CG, most of them from the game or 'imagined' from the game. None of the scenes take place after the ending, game-wise.

Lock and Celes most certainly do not get married.
