My suggestion is put in a 7 word rule. My son was not allowed to answer a question without using 7 words so he did not say yes sir or no sir. he had to elaborate. The good RC's will dictate conversation. They will ask about life, school, maybe a few about baseball but not difficult. They are wanting to build relationship with your son. The good ones know how to talk teenage boy. The bad ones ask stupid questions and only talk a few minutes. Most of all tell him to be honest and enjoy it. Not life or death.
