And whos that?!
For those whove only been with the show since the word Run!
or thereafter, heres a quick catch-up.
He hates the Doctor, probably more than any other enemy hes ever encountered.
This throws up the idea that were simply over-thinking it.
It would have been a left-field choice before the brief return of the Time Lords inThe End Of Time.
If he ever defeats the Doctor, he would have access to all of his experiences and lives.
He would essentially become the Doctor, albeit with all his rage and darkness brought to the fore.
And thats what makes us believe hes the Valeyard.
Thats my theory, until Steven Moffat and co. say otherwise.
