Those, like me, who think a planet of rude, arithmetic-loving hobbits isn't a very appealing place to live may wonder what tempts the Doctor to stay there. Perhaps he loves The Big Bang Theory. The locals, called Qomar (not Komar or Bomar, we've already met them. What's wrong with this quadrant? O.K., the Alpha Quadrant has the Orions and the OH-ree-ons, but it doesn't have Romulans and Cromulans. Where's Slartibartfast and the Raxicoricofallapatorians when you need them? But I'm off topic...) have never heard anyone sing before, mainly because they never go outside where they'd inevitably meet inferior people. They swoon over the Doctor and immediately convert factories and concert halls into shrines to his glory.
Still, I can't be the only one who thinks a tiny singing holodoctor is a great gift idea!
Average-looking bald guys across the entire world are rubbing their hands together in excitement as the planet goes goo-goo for the guy made of math.
But the Doctor has a very low Humility Setting and quickly becomes a boorish buffoon. Janeway tries to appeal to his sense of duty, but it would appear that fame and adulation are appealing to some people.
"Virtuoso" features the contrived departure and humbling return of the Holodoc. And whoever appreciates him least probably deserved to lose him.
