I walked away from the Last Great Time War. I marked the passing of the Time Lords. I saw the birth of the universe and I watched as time ran out, moment by moment, until nothing remained. No time. No space. Just me. I’ve walked into universes where the laws of physics were devised by the mind of a madman. I’ve watched universes freeze and creations burn. I’ve seen things you wouldn’t believe. I’ve lost things you’ll never understand. And I know things. Secrets that must never be told. Knowledge that must never be spoken.
"We all change, when you think about it. We’re all different people all through our lives. And that’s okay, that’s good, you’ve got to keep moving, so long as you remember all the people that you used to be."
