"They did what...?" "I'm sorry?" "They left her where?" "Just... in the street." "The street. They left her in the street. They took her face, and they just chucked her out and left her in the street. And as a result, that makes things... simple, very very simple. Do you know why?"

This was truly the Doctor who fell in love. This was also the Doctor that died for love. The only Doctor born from hatred and war and redeemed through love. So much that the thing that he chose to die for was love itself. Ten was born from love and died half-mad. Eleven was born half-mad and we see where he is now. But nine was born in fire and love is what made him finally stop burning. <--well said!
