Theory:Doctor Who prose discontinuity and plot holes/Timewyrm: Genesys


 * Ace remembers visiting Paradise Towers. However she never did, that was Mel.
 * As a retcon established later on, this was an error in the Doctor/TARDIS return of Ace's memories.
 * That also doesn't work though. The Doctor explicitly says that it's only a few minutes before(ie. when Mel had been gone from the TARDIS for years), that the Doctor accidentally took Ace's memories. And that Ace's memories were all together in one file, which he then returned to her. There's no chance for the Doctor to have taken Mel's memories, or even if he had, for one of Mel's memories to end up with Ace's memories.


 * This story supposedly takes place directly after Survival. However, the comics had already established that the "Mandragora Arc" that takes place directly before, during and directly after Season 26 was all linked, and only ends with the comic The mark of Mandragora.
 * I'd say Ace's memory loss and subsequent faulty return in the book's opening chapter lends itself to the idea that the story's supposed placement is inaccurate. Its placement in relation to Survival doesn't have any bearing on the story.
