8. At The Time Of The Events Documented In Rose, How Long Has It Been Since The 9th Doctor Regenerated?
The only indication that the Doctor is newly regenerated is based on his remarks made after catching a glimpse of himself in the mirror. Its hard to believe that he has been in this body for too long if he hasn't had the chance to see what he looks like. Arguably, he simply might not have had time in all the excitement to have even changed his clothes from his previous regeneration. If you look at the 8th Doctor's recently updated look, the case could be made that the 8th fell in battle, the 9th rose and never looked back. Nine doesn't seem the type to be preoccupied by his looks or his wardrobe, so maybe he just simply couldn't be bothered to have checked his new body out. Or perhaps his guilt over his actions in the Time War was so great that he couldn't stand the thought of looking at his own face. But surely, he must have had to brush his teeth or shave at some point? There are various pictures displayed in this episode showing the Doctor throughout history but traveling without Rose Tyler. Were these adventures that occurred when he disappeared in the Tardis for what seemed like seconds near the end of the episode or were these adventures he had prior to meeting Rose?
