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


 * 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


 * The Rani can check that the Doctor's hearts are beating simply by placing a hand on his chest.


 * The Doctor is able to check Mel's pulse with his 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 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.


 * 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?
