"MASTER CHIEF taps the side of his head, as if checking his hearing. CORTANA: ... What are you doing? MASTER CHIEF: Are you talking to me? CORTANA: Who else would I be talking to?" A moment that isn't really necessary for hardcore gamers or for those familiar with the plot, the writer manages to make a nice "Master Chief - Cortana Moment" out of an exchange that explains why the Chief is going to spend the next two hours listening to a (mostly) disembodied voice.
