I kissed you. I did it to save you, but I kissed you. I could have done it any other way, but I kissed you. I could have taken your hands in mine, looked into your eyes, drawn it out of you. I could have wrapped my arms around you, absorbed the vortex. I could have done so many things differently, all of them as effective as the next, some more effective than others, but I kissed you. It wasn't even the best way to do it, not logically at least. And I know I took advantage of you. I don't know if you'll ever forgive me. I don't even know if you'll ever know why you'll never forgive me, or if you'll ever know why you should hate me.
If you had just seen how beautiful you looked... The wind whipping your hair around, the tears rolling down your cheeks, the anger that crossed your face as the Emperor Dalek claimed to be immortal... It was beautiful, and scary, and so wonderful. And you did it, Rose. You did what I could never do. You exterminated the Daleks, completely and totally, without killing another race with it.
You see, I couldn't do it. I couldn't set off the Delta Wave. I couldn't sacrifice so many innocents, not again. I couldn't kill the human race as I did my own people. I couldn't, and you know why?
Because I'm in love. I'm in love with the smile on the face of the old lady, as she walks down the street with her groceries for one. I'm in love with the laughter coming from the four-year-old as his mother pushes him on the swings. I'm in love with the single mother, a baby on her hips and another monopolising her free hand, wondering why she was blessed and cursed at the same time. I'm in love with the smell of chips, after a long, emotional day.
But most of all, Rose, I'm in love with you. And I kissed you because of that very reason. I shouldn't have, but I did. And I'm sorry, Rose, because now I'm different. I'm a new man, with new mannerisms and new hair and new teeth. My grin won't be the same, and my hands aren't quite as calloused as before, but it's still me, and I still love you. That much will never change, not in any of my remaining incarnations.
