Dark and twisty

When Derek proposed to Meredith he said this:
You got me into the OR. If there's a crisis, you don't freeze. You move forward. You get the rest of us to move forward. Because you've seen worse, you've survived worse. And you know we'll survive too. You say you're all dark and twisty. It's not a flaw. It's a strength. It makes you who you are.

I want to remember that quote, because maybe it's true of me too. Maybe it's not always bad to have darkness. Maybe, sometimes, darkness can bring strength.
