"Am I your daddy?" (plot bunny)
16 years ago
I just got through watching Doctor Who. Specifically "The Empty Child/The Doctor Dances". For those of you who haven't finished watching an episode that aired nearly four years ago, here be spoilers.
The episode's resolution hinges on the nanogenes recognizing Nancy's DNA and correcting their interpretation of Billy's. It occurred to me, shortly after that episode ended, that they could've gotten it wrong again and simply tuned Billy and Nancy into gasmasked rubber hermaphrodites.
I see your ears have pricked up.
So they get transformed. The nanogenes get it wrong in such a way that they can be transmitted by sexual contact. They also program Nancy and Billy to "heal" as many people as possible, wink wink. Did I mention that they're now functionally invincible?
Insert joke from Jack about how he's normally open-minded, but-" here.
Cut to a few years later, and aliens land on earth, like they seem to every twenty minutes in Who. They open the door of their UFO, only to find a few billion contagious herms.
Who now have a spaceship of their own.
ALTERNATE ENDING: Our heroes are assaulted, but manage to fight their way to the TARDIS. But not before one of them is infected...
