Theory:Doctor Who television discontinuity and plot holes/The Lodger


 * In The Lodger, the Doctor seems unable to tell how much earth currency is. "I can never tell..." However, in Voyage of the Damned, David Tennant's Doctor can easily convert Earth money into Credits in his head in a matter of seconds for Mr Copper. He seems to have a very clear idea about the value of Earth money. Unless this is just a difference in Matt Smith's Doctor compared to the 10th.
 * 11 is also much less clear than 10 on what it takes to be a "normal bloke", and other Doctors have varied pretty widely on this in the past. Also, his babbling about which century is the recent one would have been completely out of character for 10.
 * Ten was also apparently unclear on financial issues occasionally. There were the "where do you get money?" bits in The Girl in the Fireplace and The Impossible Planet, though he may have been deliberately being funny.
 * This may not just be a personality issue. In series 2-4, we were watching a Doctor who'd been spending a lot of time in early 21st-century London, and traveling around with a human from that period even when he was elsewhere. Now, we're watching a Doctor who spent the last few years wandering through space and time without a companion, with only a few hours of that spent in early 21st-century England, before finally picking up a companion a few days ago. So, his memories of modern England wouldn't be nearly as fresh.
 * There is also the possibility that Eleven was being ostentatious on purpose, knowing full well that barging in and handing Craig a bagful of 3000 quid would cause Craig to let him have the room without objection much more surely than if he'd just had the normal amount of rent. It is after all implied that he also had something to do with the previous lodger suddenly getting a windfall inheritance from a previously-unknown uncle and moving away on short notice. If so, he basically secured his lodgings in the house by throwing around quite a lot of money.


 * Isn't it against the rules in football to take a free kick that is supposed to be taken by another player?
 * It's perfectly within the rules. You see teams who line up more than one player in an attempt to confuse the goal keeper.


 * The first time the Doctor contacts Amy since the TARDIS's dematerialization, she knows about the flat upstairs, even though the Doctor has not mentioned it.
 * It comes across quite broadly that they had been watching the house/flat for sometime, with them discussing the problem of the time issues coming from there.
 * No, it doesn't. The Doctor reveals the only reason why he went there was the note from Amy, which her present self was still to write. And at the beginning they were trying to visit another planet. There is no evidence saying they've been watching or discussing it for some time and it was only one day later when the Doctor moved in.


 * When the alien ship leaves, it should have left a hole in the roof of Craig Owens house. How else would the people have been able to enter it from inside the house?
 * The perception filter probably meant they were probably teleported upstairs, just that they were made to think that they were walking up the stairs.
 * The stairs themselves could have been part of the ship. So when the ship left, it took the stairs with it and just left the intact roof.


 * When the Doctor headbutts Craig, the ninth Doctor appears before the tenth.
 * He never said it would be in the correct order.
 * Surely nine normally comes before ten, or have I been counting wrong all these years....
 * It went 11, 9, 10, 8, 7, etc.
 * Maybe his ninth incarnation had just been on his mind for some reason. Again, there's no reason that he had to be seeing the Doctor's faces in chronological order.
 * Run through the sequence on freeze-frame and it goes 11, 9, 10, 8 and Lucie Miller, 4 and an Ood (!), 3, 2, then 1 - 7, 6 and 5 do not appear.


 * Where did the doctor get three thousand pounds from? He doesn't carry money, and he has only been here for a day, so where did he get that much money?
 * From an ATM like on "The Runaway Bride"


 * If their future selves can leave their past selves messages to get them out of trouble, why don't they do that all the time they get into trouble?
 * It's generally "against the rules", for lack of a better term - as this had already been done there was little way of backing out it.
