Which line from "lather and nothing else." best reveals internal conflict

In any internal conflict, there is always a problem from which a struggle stems. From the beginning of the story, the barber’s problem is evident when Captain Torres enters his shop. When Torres takes a seat, the barber estimates he has a four-day growth of beard and takes note that it was the four days Torres was on a foray against his fellow revolutionaries. At this point it is clear that two opposing political parties exist. The barber’s problem now is that he has an enemy in his shop with the ability to send him to his death if he so much as suspects the barber of ill intentions.
