TEGAN: I left you, remember? Found myself on the bank of the Thames with a load of dead Daleks. Long story but, in the end, I got myself back to Brisbane, and it took a while. I think I was in shock. I thought, "What can I do with my life? What can I do that would make the Doctor proud?" So I started campaigning for the environment, and I used every trick you taught me. To never give up, to never be defeated, to keep fighting even in the darkest of times. And, oh! There were some times I thought, "He would be proud of me."
