Theory:Doctor Who audio discontinuity and plot holes/Fitz's Story


 * The Doctor mentions that he and Sam spent time on Entuso previously. However, as Anji is traveling with them, Ancestor Cell(and Eight's subsequent amnesia) has already occurred, and thus the Doctor should not remember Sam.
 * Maybe he meant Samson Griffin.
 * I point back to Eight's current amnesia: he really shouldn't remember any of that. Even if he meant Samson(which he most certainly did not), depending on where the audios take place relative to the novels, the Doctor should have no memory of them regardless.
 * He has been able to recall certain things in the novels post-Ancestor Cell, but it's always been a jumble of memories that he's remembering as one. It's never been as precise as his memory about Sam in this one.
 * Either he's found and reread a recent entry in one of his hundred-year diaries, or he was reading off the TARDIS databank entry for the planet of Entuso, which should give hime the same basic rundown he gives Fitz, albeit presumeably with a more formal eloquence.
 * The Doctor's memory of pre-The Ancestor Cell events did not all come back to him at once, but rather bit-by-bit. For example he recognises the Master in The Adventuress of Henrietta Street(set before Fitz's story). It's entirely possible that this memory of this one adventure with Sam had come back to him, while most of his memory remained lost.
