"You need new friends, Cas."
"I'm trying to save the ones I have, Dean."
Why don't they understand? What I do, I do for them. These humans, this place—they need help. They need more than a simple angel hand attending them, so it falls to me to be more than I am.
The watcher of this world no longer; I will be its newest saviour. For them. For this world. For my Father's magnum opus, though he cherishes it no longer. There is at least one who still does, and I will let no sacrifice be in vain.
I may lose everything—perhaps even myself—but at least they'll live.
