*sigh* 'twas "The Departed", Det. Mike Sullivan.
HINT... another Martin Scorcese movie.
"Saving someone's life is like falling in love. The best drug in the world. For days, sometimes weeks afterwards, you walk the streets, making infinite whatever you see. Once, for a few weeks, I couldn't feel the earth - everything I touched became lighter. Horns played in my shoes. Flowers fell from my pockets. You wonder if you've become immortal, as if you've saved your own life as well. God has passed through you. Why deny it, that for a moment there - why deny that for a moment there, God was you?"
