“School Reunion” offers chilling insight into the dark truth he believes about his life. The Doctor knows he can’t have a companion with him forever. That lack of foresight comes back to bite him in “Doomsday,” when he loses Rose permanently. He’s almost willfully put off thinking about them, such as his relationship with Rose, taking in the joy of it without thinking about her home life. He was loose, spontaneous, innocent, wide-eyed, and in some ways, naive about the human consequences of his life. The Doctor with Rose was a tad less mature and a bit less responsible, and could afford to have fun. Ten was more carefree than Nine, and compared to his later self, Ten was sometimes less aware of the importance of people around him (such as Mickey Smith, who had never measured up to his respect when he first met him in his ninth regeneration). Ten shared the cocky streak of Nine, but it was tempered a lot by his own renewed amazement with life around him, and the humanizing influence of his companions, as well as by the continual losses he faced throughout his regeneration. Nine was quite rude and often insulting of humanity, and if they acted stupid he wasn’t afraid to call them out, and that attitude itself was a result of the bitterness inside of him due to the Time War. It’s his Nine-self that was rude, his Ten-self that was beginning to see that that kind of attitude wasn’t the most ideal.

When he chided Rose for not trusting him post-regeneration, he remarked: “Is that what I am, rude and not ginger?” (“Christmas Invasion”). Ten was at first ruder than the self he became later, part of the hangover from his ninth regeneration. Rose made him human, and that trend would continue with each companion he meets, until that very vulnerability opens his heart so much that it is hurt almost irreversibly after he loses everyone he loves at “Journey’s End.” Rude and Not Ginger The Tenth Doctor is very vulnerable, and malleable by the people he cares about. The reason he raves about the splendor of humanity the moment he emerges in his new body in “Christmas Invasion” is a direct result of the humanizing influence of the woman who changed his life. It was her love, and her humanity that changed his worldview on the human race, from “stupid apes” (Nine) to people “full of potential” (Ten). The Doctor did love Rose, and it was her love and care for him which directly aided him in recovering from the hardened, vengeful soul he had grown into because of the Time War. It’s been said that the Tenth Doctor was born out of love, and I believe that’s true. It was at this point he absorbed the Time Vortex from Rose Tyler, to save her life, and regenerated. Nine finally absolved himself from the mass murder he committed by choosing to be a coward, and not to kill so many lives again. We first meet the Tenth Doctor just after a crucial juncture in the Doctor’s overall characterization, particularly the defining guilt that he’s been carrying in his Ninth incarnation about his final action in the Time War, namely the destruction of Gallifrey for the sake of all creation (proof of the veracity of this action here: x).
