And we've still a got a mystery as to the truth of the Doctor
We know John Hurt plays a Doctor, but we don't know if he's a suppressed past regeneration or a future regeneration. That is unless I missed something. It'll be tomorrow when Itunes downloads before I can rewatch it.
Hurt could be the first Doctor, one before Hartnell. The Doctor did say his name was like a promise. What better way to atone for being a "tyrant" than becoming a healer.
