Theory:Doctor Who television discontinuity and plot holes/Children in Need Special


 * How does the Doctor know that Jack is Okay?
 * An unknown amount of time transpired between when he kissed Rose and when she regained consciousness inside the TARDIS. As was later revealed in Utopia, the Doctor knew that Jack had become a fixed point in time. Logically, he therefore located Jack during this unknown amount of time and deduced what had happened to him (or else his Time Lord time sense told him that a fixed point in time had come into being at the position he last knew Jack had been occupying).


 * The Doctor seems to be much more stable before he finally began to show the trauma. How could this have happened?
 * This is consistent with previous regenerations. He goes back and forth between stability and instability before he "settles down".
