I’ve been running. Faster than I’ve ever run. And I’ve been running my whole life. Now it’s time for me to stop. And tonight I’m going to need you all with me.
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.
