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 Tennants 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.


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