Day 22: Favorite Friendship... the Doctor and Donna. They had a great relationship. After the mess with Martha, the Doctor just wanted a friend and Donna delivered. She understood him in a way no one else did, except for maybe Rose. They were so much fun to watch together and it was awful to see her go.
-DONNA: Is that what you said to her? Your friend, the one you lost, did she trust you? DOCTOR: Yes she did and she is not dead, she is so alive.. now jump!- Can you see that spark of tear in his eyes ?
Wilf: Doctor? What about you now? Who have you got? I mean, all those friends of yours. Doctor: They’ve all got someone else. Still, that’s fine. I’m fine. Wilf: I’ll watch out for you. Doctor: You can’t ever tell her! Wilf: No, no—but every night, Doctor, when it gets dark, and the stars come out, I’ll look up on her behalf. I’ll look up at the sky, and think of you. Doctor: Thank you.
