In the End of Time the leader of the Timelords states: "The vote is taken, only two stand against and will stand as monument to their shame: the Weeping Angels of old!" (36 minutes into End of Time part 2) And the two Timelords and standing, covering their eyes like the Weeping Angels.
The Doctor describes them as being "the only psychopaths in the universe to kill you nicely," and say that they evolved from the beginning of the universe. However, these exact Timelords are sent back to the time-lock at the end of the very same movie. So, are these two Timelords the progenitors of the Weeping Angels? Is this a common punishment among Timelords and thus OTHER older Timelords are the original Angels, or are they from somewhere else entirely?
