Theory:Doctor Who television discontinuity and plot holes/The Woman Who Lived


 * When Me reveals her plan to use someone's death to open the Eyes of Hades, the Doctor mentions that death rips a tiny hole in the universe, thus implying that death is unnatural. However, earlier in the season (UtL/BtF) the Doctor condemns the Fisher King for hijacking the natural process of life and death. Breaking this cycle was so devastating for timespace that the TARDIS wouldn't go near the 'ghosts.'
 * Those two concepts aren't necessarily contrary. The "tiny hole" the Doctor speaks of (possibly metaphorically) may well be a natural part of the universe's cycle, so long as it's not exploited by a massive energy source, as it was here.


 * Although Me's journals are a plot exposition necessity, their actual existence within the narrative is almost impossible. The first journal the Doctor reads was supposedly written on the day he saved Ashildr, and she now has hundreds of journals. How could she have possibily carried all these books with her as she journeyed through her miserable lives?
