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. Thoughts? (unsigned comment by User: 87.113.183.222 talk)
 * 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.
 * 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.
