At no point in time could we have stated with 100% accuracy that Death in Heaven Osgood was an impersonator. It's true that we now know she was the Zygon, but we also know that the Zygon wasn't claiming to be the human.

(Yes, there's an easy counter to this claim, but I have to move the discussion along somehow...)
