This story takes place over an outstandingly long period of time, seeing the Doctor stuck in a recursive cycle during which he repeatedly perishes and comes back to life. In the following episode, Hell Bent, it is estimated that this cycle lasts for four and a half billion years,
My question is, if Doctor dies today, and he gets back tomorrow without the knowledge of the previous day, shouln't he met freshly died body, not the skull instead? Shouln't he felt that the skull is recent not old?
I mean..okay, after one billion year it's ok to see skulls, but after one day?
