"Crazy fool! Why do you always jump!? One of these days you're gonna land on something as stubborn ad you are, and I don't do bits n' pieces! Where is she? ...where is Cortana?" - Avery Johnson (Halo 3)
A quote that is rather applicable once more after Halo 4. I keep thinking the next game is going to be about searching for Cortana, and Chief as always leaves a trail of destruction behind him.
