When our Doctor messes up with an experiment that breaks a law of …something or other, what will happen as they get shot off to a universe that already has their own Doctor, one with his own past and own future? Will the universe be able to contain the two wacky, raggedy Doctors, or will they end up being the destroyer of the bi-universe?

Is real only a matter of perspective?

Inspired by the Dischord Whooves_Bad Apple [PMV]. Seeing two Doctors multiple times at once got this idea in my head, and it just came out while being an insomniac.
