The Doctor: I've dealt with with far worse than this, beyond anything you could imagine! And if I can't protect the only things I care about then what would I be?! Twilight means everything to me. And I can't always be there for her even though she's lonely. But that doesn't mean I can't keep her or the things she cares about safe. We've lost those who are precious to us. You want to hold on to what's left for their sakes, don't you? You would do anything to keep those things safe, absolutely anything to make the world good for them! Well that's my whole life!! That's me carrying the dreams of so many lost lives! And with all of those memories and all those hopes- I WILL PROTECT THEM!
