>Tell me about Bane! Why does he wear the mask?
Here the narrative seems to be inconsistent. CIA already knows about Bane, but still asks for information about him. Is this a contradiction? No. It is a reflection of CIA's homoerotic obsession with his target; it is both a possessive lust to know as much as possible about Bane, and at the same time a jealous rage against those who may even know more about his target than he does.
CIA also poses the question "Why does he wear the mask?" to the prisoner. This can be interpreted literally, as Bane does indeed wear a mask. However, it is also a question which goes right to the heart of what it means to be human, for each of us in our daily lives wear a mask to conceal who we really are, and present ourself to others in different ways. This is a facet of our nature which has been noted since ancient Graeco-Roman times - the notion of the "personality" (a term derived from the Latin word "persona", meaning "mask"). The question therefore takes on eminently psychological and philosophical dimensions.
>Lotta loyalty for a hired gun
At this point, CIA is clearly frustrated, as the mercenaries in his power are not prepared to yield to threats of death or torture.
Here, Nolan is inverting the ancient trope, found in the works of great philosophers such as Plato, Aristotle and Machiavelli, about the apparent unworthiness and unreliability of mercenaries as a fighting force. According to these eminent philosophers, a mercenary's fealty is notoriously dubious, since they only seek payment, and are incapable of lasting loyalty to their paymasters. Now, they are depicted as being loyal to their cause to the bitter end.
Contrast this, too, with the actions of CIA, a man acting in the loyal service of his own government, but using crude and brutal methods to try to induce his prisoners to talk, methods which are both illegal according to national and international law, and also incompatible with the values of justice and order publicly espoused by his own country.
