Mihawk (about Luffy): I decided to let him go.
Garp: I specifically told you to bring him to me.
Mihawk: Come now, Vice-Admiral. I don't take orders. Not even from the likes of you.
Garp: As one of the Seven Warlords, you serve at the pleasure of the World Government. Without our immunity...
Mihawk: I would still do precisely what I want. No more and no less. And what I want is to see what becomes of that young man when he enters the Grand Line.
