DOCTOR: 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 walked in universes where the laws of physics were devised by the mind of a mad man.

I've watched universes freeze and creations burn. I've seen things you wouldn't believe. I have lost things you will never understand.

And I know things. Secrets that must never be told. Knowledge that must never be spoken. Knowledge that will make parasite gods blaze.

So come on, then. Take it! Take it all, baby! Have it! You have it all!

“If this universe has taught me anything, it's that you should always hold onto every moment you can, every hour, every minute, every second. Even when all hope is gone, you should still cling on, because you can never know what fresh hope the future may bring.”
