Donna: I want to stay.
The Doctor: Look at me. Donna, look at me!
Donna: I was gonna be with you. Forever.
The Doctor: I know.
Donna: Rest of my life. Traveling. In the TARDIS. The Doctor Donna. Oh, oh my god, I can’t go back. Don’t make me go back. Doctor, please! Please don’t make me go back.
The Doctor: Donna. Oh, Donna Noble. I am so sorry. But we had the best of times. The best. Goodbye.
