1. The Day Of The Doctor
You see, when you have spent so many generations worth of Time doing things in The Name Of The Doctor then it all builds up in you. There has to be a lot of guilt in there all festering away that has to go somewhere. No wonder he talks about running away from something all the while. As of writing this the 50th-anniversary episode is yet to be shown, but think about it - things must be bad if The Doctor spent over 900-years in denial and evasion, surely? Also, we wonder what mad logic must be about to prevail as he confronts his origins. Apparently he did what he did, "For the sake of sanity." Perhaps we might be about to find out that, as Voltaire so aptly put it,
"Every man is guilty of all the good he did not do."
Whatever the outcome we can surmise that the pressure was probably enough to unbalance even the best of us. Why, it's almost as if none of us is that far from the edge of sane reason and that we ought to be more accepting of The Doctor and his rather odd seeming ways. His actions might just tell us something about ourselves.
