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


 * 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.


 * 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?
 * Pig Slaves were used most probably.


 * Why does Dalek Sec have bigger tentacles than other Daleks? And why does he a sack-like appendege?
 * 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.
