The Frenchman is downstairs playing Kingdom Hearts. he's on the very first level where you have to beat Riku. He finally figured out how to do it (after loosing 15 times), so now he has to beat him 16 times. Even though he already won once, he has to proove himself better than the game. Aerith did practically the same thing.
And they wonder why it's easy for me to study and/or fall asleep while they're playing these things. :)
