Theory:Doctor Who television discontinuity and plot holes/Robot of Sherwood


 * How does Clara know what type of life the Doctor was born into? According to her, she has been there since he started running, which means either since he took the TARDIS or (according to the 10th Doctor) since he looked into the Time Vortex.
 * It is highly likely that the Doctor simply told her at some point, although in a Doylist sense, that line could have just been a soft metaphor for the Doctor being born a Time Lord who later saw and sympathized with the plight of lesser races. It doesn't have to be strictly literal, but if it is then it isn't much to assume that the Doctor just told her.
 * Don't forget that she saw, and was inside, the doctor's timestream so it's likely she saw the whole of his life, including what sort of upbringing he had, while in his timestream.


 * How does firing the golden arrow at the side of the robot's ship mean the the engine then has enough gold leave the atmosphere?
 * It's possible that even the proximity of gold would give some power to the engines, albeit not as much as if it had been applied like most of the gold.


 * Why would robots need slaves? Aren't they essentially an expendable workforce?
 * They don't necessarily view themselves as such. They are also on a quest to fulfill their mission of reaching "the promised land".
