^ Didn't the VOY episode Survival Instinct have something similar to what you describe with Hugh? Survival Instinct with the 3 former Borg drones who kept hearing the thoughts of the others in their little group. This after they were beginning to rediscover their individuality after being separated from the Collective.
The Queen does seem like a superfluous redundancy.
Unimatrix Zero also is a contradiction. However, what Hugh describes is something normal to the Borg experiences. The Voyager episodes describe something that the Borg actively suppress. this is another area in which the hive analogy fails: the Borg consciousness is not natural, but forced.
