I love this dialogue from season one. That Look Nine has when he's talking to Jackie but looking at Rose. All of the human race at stake, and she understands it. And he realizes just how brave she is. And for a moment, that bravery keeps both of them going.
"... there's me." It's moments like these where you realize how Rose completely saved the Doctor. He was in self-destruct mode until this pink and yellow human healed his hearts and taught him to love again. (Love this photo and the commentary here!)
