Elite Guards are elite elites, yes.

@DCC - He'll appear in another poster.

Nightwatcher didn't appear because he's evil. He will be a special character. The NPCs and bosses will have different dialogue with him. He may be an unlockable or something (unlockable early in the game, because there may not be a save feature).

Also, playable characters may talk. Still deciding.
