ok, diz says that riku is twilight in twilight town. in the end of the game riku chooses the middle path and diz say "you choose the road to twilight" and riku says "no, of dawn". So..at the end of CoM look at riku's trenchcoat, and then watch deep dive and you'll see that the guy ontop of the building that is blindfolded has the exact trenchcoat. also when he said the road of dawn, meaning twilight...the path lead him to twilight town, and deep dive occurs in twilight town.
