River Song: When you love the Doctor, it’s like loving the stars themselves. You don’t expect a sunset to admire you back. And if I happen to find myself in danger, let me tell you, the Doctor is not stupid enough, or sentimental enough, and he is certainly not in love enough to find himself standing in it with me!
Doctor: Hello, sweetie.
