Theory:Doctor Who television discontinuity and plot holes/The Eleventh Hour


 * The selection of clips displayed by the Atraxi vessel includes recognizable footage from events the careful viewer knows didn't happen on Earth, or at least didn't happen on the Earth of the time in which the story is set. The opening Cybermen clip is recognizably from the moment they crashed Pete Tyler's party in Rise of the Cybermen. Likewise, there's a shot of the Vashta Nerada-controlled skeletons from The Library. There are also glimpses of Hath, who might have come to the "standard universe" Earth at some point, but not as early as the 21st century. It is unclear why the Atraxi are seeing these particular images. Perhaps it suggests they have some ability to see across parallel timelines, or indeed have some ability to look into the future. Perhaps it indicates that they have accessed UNIT computers, which might have included formal reports by Martha Jones, or Torchwood computers, which would have included information on the Cybus-created Cybermen. The inclusion of the specific image of the Vashta Narada perhaps indicates they've scanned The Library computer at some point — though, again, this would imply they have some time-traveling capabilities. It is also possible they were somehow scanning the Doctor's memories.
 * The Doctor did state that the Atraxi followed him and were "only late because he was" which suggests that the Atraxi do have at least some level of time-traveling capabilities.


 * The prominent shot of the London Eye and the Millenium Dome in the opening sequence creates a bit of a narrative problem in dating the episode.
 * The Tardis could have travelled back in time between the 1st scene and crashing into Amy's garden.
 * The date is unknown on when The Doctor was hanging out the TARDIS. It could of been 2005 when The Doctor last left of from. If it was then The Doctor could of travelled back to 1996 because the TARDIS could of ended up anywhere after it was damaged


 * In Amy's house, how does the Doctor know that Prisoner Zero is a multiform when he has not seen it?
 * The Atraxi may have sent more information to the Doctor's psycic paper. Or maybe he recognised the glow underneath the door?


 * The Atraxi looks into Amelia's room which is bright compared the prison, shouldn't it's pupil dilate?
 * Maybe they have other systems in their eyes/bodies for adjusting to different lightings, maybe their pupils only dilate for extreme changes. Or perhaps, as they are not human, what looks like pupils to us, may serve a completely different function for them.
 * Faced with bright light, the pupil should contract, not dilate.


 * In the opening scene, the TARDIS windows are clearly intact, despite having been blown out at the end of DW: The End of Time
 * Maybe they are made of some kind of self-regenerating material in which case they could have fixed themselves.


 * If Amy has spent most of her life talking about the doctor and the TARDIS, etc., then why hasn't she come to the attention of Torchwood?
 * Who says she hasn't? Lots of people know about the Doctor—the conspiracy theorist from Rose, the LINDA club, etc.—but apart from a notation in the Torchwood files they seem to be left alone.


 * In the rooftop scene in the hospital, when they step onto the roof the doctor is carrying/wearing various ties, but he has neither the red bow tie or tweed jacket which he is wearing at the end of the scene with him.
