The fighter. The lover. The friend. Just don't think that 9 is the fighter, 10 is the lover, and 11 is the friend. In every regeneration each one is all these things. Remember, they are all the same man.
Quote from Dr Who: Rose Tyler: I am the Bad Wolf. I create myself. [Rose lifts her hand and takes the words from the Bad Wolf Corporation sign] Rose Tyler: .I scatter them, in time and space. [the words float off away from them] Rose
"What use are emotions if you will not save the woman you love?" Everyone thinks of 10 when they think of the Doctor and Rose, but they fell in love when he was still even if they never would of admitted it then. <--- I second that statement.
Why didn't I notice this before? And now the rest of my feelings are broken. I'm beginning to think that it's not a good thing for them to bring Rose and 10 back for one more episode, I had barely gotten over them being gone and now.
