Theory talk:Doctor Who television discontinuity and plot holes/The End of Time

Why is the doctor afraid of the master firing missles at them when they are 100000 miles from earth no missle can reach them that far from earth

Master or Missy?
In the final scenes of "The Last of the Time Lords" we see a female hand pick up the Master's ring, and yet The Master has the same face in "The End of Time". Is this a misdirection or some regeneration side effect?
