As I see it the dudes just come from the Time War and committing genocide against his own race- he's almost definately gonna be suffering from PTSD- his capacity for pant wetting violence is still there but he's mildly repulsed by the fact that he could and did do what he just did- think of a rabid bear in self inflicted restraints.binnsyboy said:Agreed.
My doctor would be something I wouldn't have to struggle to play, flippant, cynical, but loves a laugh. And I'd cure something that's bugged me for a while. Yeah, the Doctor's slightly pacifist, but he never gets his hands dirty anymore. I mean the Sixth Doctor knew martial arts. Or the Third. My memory's off here. And at least Eccleston would have gone to violence when it suited his character. "Oh, aren't you fun?" "Let me out of these manacles, I'll show you how much fun I am." *Stern Face* and when him, Jack and that ginger girl were arrested, he beat up one of the guards in their escape.
But then my interpretation of the Doctor has always been a little on the dark side, so I may be far wrong.
