Winston: Why would you do this? Of all the things you’ve told me, this I find hardest to believe. Why would you invite your friends to see your death?
The Doctor: I had to die, I didn’t have to die alone. Amy and Rory; the last centurion and the girl who waited. However dark it got I’d turn around and there’d they be. If it’s time to go, remember what you’re leaving, remember the best, my friends have always been the best of me.
Winston: …and the woman you spoke of, she was there?
The Doctor: Yes, she was there. River Song came twice.
