Fast track for promotion

In "Starfleet" for half a day and already he got made a Lieutenant. I bet Harry is off sticking his head in the warp core about now.

And yes The Doctor did make his own private Starfleet out of the primitive natives of this planet. Guessing when Starfleet programed him they didn't bother with minor things like the Prime Directive.

Who needs the Prime Directive?

SPOCK: Then the Prime Directive is in full force, Captain? 

KIRK: No identification of self or mission. No interference with the social development of said planet. 

MCCOY: No references to space, or the fact that there are other worlds, or more advanced civilizations.
