Doctor: If I don’t dare, everyone dies.
Rose: Do it.
Doctor: You don’t even know what it is. You’d just let me?
Jackie: Please, Doctor, please, she’s my daughter, she’s just a kid.
Doctor: Do you think I don’t know that? ‘Cause this is my life, Jackie - it’s not fun, it’s not smart, it’s just standing up and making a decision because nobody else will.
Rose: Then what are you waiting for?
Doctor: I could save the world but lose you.
