[quote]Is this what you wanted? Is this what you were looking for? [/quote] Who Chief is addressing is up to debate. It seems like he directly references Locke's mission when he asks, "is this what you were looking for?" I believe he addresses himself very briefly when he looks at the monument and asks, "was it?" His tone isn't that reflective of the deep questions you think he is asking himself. He sounds angry at Locke. There is also the viewpoint that if Master Chief is addressing himself, then he is basically saying everything he has done in the game so far was worthless. So to us viewing it all of his actions prior to this moment seem like they amount to nothing.
