“Rose, before I go, I just want to tell you, you were fantastic. Absolutely fantastic. And you know what? So was I.”
— Ninth Doctor, The Parting of the Ways
I am not going to say much about this quote, because I’ve already said so much about the Ninth Doctor’s transformation over the series, and I don’t want to repeat myself at this stage. But I will say something, because this is almost certainly my favourite part of the Ninth Doctor’s series.
You see, this is the last thing the Doctor says to Rose before he regenerates. This quotes shows the culmination of all of the changes that he has experienced. Because the Doctor that Rose first met would never have said this about himself; that Doctor did not have confidence in himself. This isn’t the Doctor being arrogant or full of himself (though we do know that he can have those qualities) – this is the Doctor coming to the realization that, though he might not be proud of his difficult past, he can still do fantastic things. In later series’ this confidence does get a bit out of hand, and the Doctor will need to deal with that, but right now the confidence is newly re-found. And it’s a great way for him to go out.
