No, I don't have titles for these things...

Vexen: Zexion! Where's Xemnas!?
Zexion: The usual place.
Vexen: The Room of Sleep? Argh, this is what happens when we need him and he sleeps...

This is me questioning Xemnas's role in KH: 358/ 2 Days. Seriously, what does Xemnas do? He appears about four times throughout the whole game and leaves. He is very disappointing for a main villain.
