An introduction makes since, and would be good in breaking the tension and increasing it a touch too. By that, my mind takes me to possibilities of being a honest interest in same path for travel, budding a friendship, with a hide rebuilding a back tension on the addiction. Foreshadowing a future story climax. Be as free with your writing of character, you play him the way you see him.
I am with Bru I always play him the way he would do it. Even if I disagree with the severity of reaction or code. He is a rather suave stick in the mud. He loves people and fairness, and at the same time his sense of personal honor is strong. For example he admires personal freedom as long as that freedom is not selfish.
