Theory:Doctor Who television discontinuity and plot holes/Daleks in Manhattan


 * How can one Pig Slave get Laszlo? I image he would scream and others would come to his aid.
 * Why not have the Pig Slaves complete the work on the mast. I'm almost certain they would get it done in the tenth of the time it took the humans to.
 * They are not as coordinated as Humans are, and so they couldn't do it.


 * Where do the Daleks get pig DNA from to turn humans into Pig Slaves. From a farm? There aren't really any farms around Manhattan.
 * It was said Diagoras was a farmer. And so he most likely had pigs, which the Daleks used


 * Did Dalek Caan send that big mental energy pulse into the Dalek-Humans when they were shooting at the Daleks with weapons lethal to them? No, he had to wait until after his two comrades were dead before sending the lethal pulse and calling them "failures". Where's the logic in that?
 * The mental energy pulse probably took some time to load.


 * How did the Daleks get to the theatre so quickly, in like under a minute, after the Doctor used his sonic screwdriver to tell them where he was, and it showed them all in the laboratory? If they had Dalek Sec (hybrid) they couldn't fly or anything, so how?
 * The Daleks could of had teleports


 * The upper floors of the Empire State Building were not complete until 1933.
 * The Daleks have advanced technology, so would be able to finish it quicker.
 * They were not complete at the end of the episode.
 * All we know is that, this episode takes place after that newspaper was printed, and so this episode could have taken place in 1933


 * If the Doctor only offered Martha one trip into the past and one trip into the future, as offered in Smith and Jones confirmed by him in The Lazarus Experiment, why has she been taken on this extra trip?
 * This is due to a deleted scene in which Martha convinces the Doctor to take a detour not a trip.
 * When the Doctor looks at the newspaper, he mentions this "detour".


 * The Daleks don't have fingers so how could they take Thay's panels of Dalekanium off him?
 * They could have used their suckers to pull them off.
 * Pig Slaves could have been used.


 * Why does Dalek Sec have bigger tentacles than other Daleks? And why does he have a sack-like appendage?
 * Dalek Sec is the leader of the Cult of Skaro, so a physical difference is not unexpected. It could very well be from preparations for the final experiment as well, it is highly unlikely a pure breed Dalek would be capable of such a metamorphosis unaltered.
 * In the same way that the Emperor was a different type and was different, Sec is a Supreme Dalek and therefore different also.


 * At the beginning the date is claimed to be November 1. If it is November first why are the leaves on the trees in Central Park not only green but still on the trees?


 * This episode takes place some time after that newspaper was printed


 * Why is there a sewer in the theatre? The stench would render the place unuseable. Not to mention I'm sure even in 1930 health and safety would have rules against that.
 * When this episode first aired, I specifically remember watching the Dalek destroy the radio after the doctor escapes. However, this scence has been cut on every variation of the episode aired since. I would have thought this would be a crucial moment in the episode not only to explain how the daleks stopped the radio but also as to when Dalek Sec picks up the debris looking at it in deep thought.
