This really does break my heart, cause you tend to forget that the Doctor was a dad once. And then you realized that he had a wife and kids, and he destroyed Gallifrey. Doctor Who punctures your heart, people.
This is why I love Doctor Who. The moments when no matter who you are or what you think of yourself, the Doctor tells you that you're important.<<<I love how one of the main messages in this show is, everything is important, and that includes you.
