 The protagonist of the story — a holographic doctor — wears a huge cumbersome backpack-like mobile emitter to get around and is constantly mistreated by his crewmates.Worse, each member of the crew is a thinly veiled allusion to an actual crewman but portrayed as being cruel or obnoxious—for example the Tom Paris character is a self-serving adulterer, Harry Kim is a hypochondriac and Captain Kathryn Janeway is a tyrant and murderer.As a further homage to the mirror universe Tuvok's character wears a goatee.
