Theory:Doctor Who television discontinuity and plot holes/The Empty Child


 * The Doctor says that only Earth uses red alert and everyone else uses mauve. This contradicts so many other things in the Whoniverse, and most importantly the red light on the chula ambulance near the end of the story.
 * No, the Doctor means that red alert is the highest alert on Earth, and everyone uses mauve as higher.


 * The red light on the ambulance was probably just to signify that it was an ambulance.


 * Whilst Jack and Rose were next to (the tower that houses) Big Ben, the clock continued to show 21:30 and Big Ben's clock never stopped during World War II, it continued to tell the time.
 * This is set in the Whoniverse, where not only are things not the same as in our own universe, but time is also in flux.
 * You don't understand! The clock is staying on the same time for more then a minute so therefore its a production error
 * You said it yourself, the production team probably just stuffed up.


 * But in the Whoniverse, the clock might have stopped.
 * Yes but the real and only answer is that the production team screwed up. There is no need to make up some excuse for this in universe.
