There is also a scene in the PV Trailer for FM+ where Xemnas gives Roxas his name and Roxas says "Roxas" then Xemnas says "The new you" but for some reason that scene isn't voiced in the game.
Get a "Key of Rewards" card and open the door with it, and there will usually be an Org card in each room. The card is really hard to get, you can only get it from battling heartless, but its rare to get it, though it comes up more as you get towards the end.
