Theory:Doctor Who television discontinuity and plot holes/Time and the Rani


 * How can the Doctor's accent completely change? Why is it Scottish?
 * Lot's of planets have a north.


 * The Doctor is wounded enough to regenerate during The Rani's TARDIS shoot-down, but Mel is barely stunned.
 * They are on different sides of the console, and he hit his head on the console; sometimes a car accident that barely scratches one person is fatal to someone sitting next to them.


 * How can the Doctor not realise that Mel's face is different from the real Mel's face?
 * He is suffering from post regenerative trauma.


 * More importantly, the Rani had given him an amnesia drug. He didn't even know who Mel was; so how exactly would he be able to "recognise" her? The Rani probably didn't even need a disguise ... at least not until the drug started to wear off; as she undoubtedly knew it would. And when the Doctor did start regaining his memory, the disguise served its purpose of extending the charade.


 * The Rani can check that the Doctor's hearts are beating simply by placing a hand on his chest.
 * Time Ladies may know of such a method.


 * If her sense of feeling within her hands is good enough, why not? Try putting your ear to someone chest and listen for their heart-beat. That's the "sense of feeling" in your ear.


 * The Doctor is able to check Mel's pulse with his thumbs.
 * The Doctor having an ability such as this is not surprising.


 * It is possible to detect a pulse with your thumbs.


 * Without appearing to make any adjustments to the TARDIS the Rani is able to patch Urak's vision straight into the TARDIS scanner.
 * She had apparently made enhancements to Urak to transmit his thoughts/vision on a general frequency.


 * She is able to shoot down the TARDIS as one would any old passing spacecraft.
 * The Rani is a Timelady, and likely has Timelord technology capable of attacking Timelord vessels.


 * In order to release the Lakertyans from the Rani's deadly bracelets, the Doctor and Mel use a fibre optic cable to complete an electrical circuit.
 * They look like fibre optic cables to us; they obviously carry electrical current regardless of their appearance.


 * Tetraps have eyes in the front, sides and back of their heads. Why, then, do they need to turn their heads when looking for something?
 * Maybe some eyes are better for looking than others.


 * The Doctor says that both he and the Rani are 953 years old. However, he has no way of knowing her age at this point, considering they are both time-travellers.
