Theory:Doctor Who prose discontinuity and plot holes/Timewyrm: Exodus


 * In The War Games, the Time Lords put a forcefield around the War Lord's planet, preventing anyone getting on or off. Yet the War Chief somehow got both to the planet, and from there to Earth after this forcefield was in place.
 * The War Lord and his men were clearly travelling to and from the planet by SIDRATs, yet the War Chief and some guards departed the war games by a spaceship.
 * In The War Games, the Time Lords erased The War Lord, The Security Chief, and all their accomplices from history. They explicitly state that it will be like they never existed at all. Yet somehow, The War Lord has a son, who not only exists, but remembers all the events of The War Games. To say nothing of the fact that he's now allying himself to the very man who was using his father, and openly betrayed him.
