First off I really am not sure if this is plot or setting. Anywho, I will do my best to explain the situation. So we have party A, that wants to negotiate with party B. Problem is a language barrier. Party C is somewhat tied politically to A, and also has an interpreter that can aid in the dialogue of A and B. Also Party C is part of the enemy fighting party B. After a brief exchange to get party A in to the building with the help of party C, there is a conflict of interest between an individual in Party B and Party C. That conflict being one that person in party C made a promise to the individual in party B to kill them next time they met. Question is would having this promise between the two individuals help to dissolve the rocky negotiation process between parties A and B, since parties A and C have political ties? Would fulfilling that promise between the two turn the negotiations into a fight between A and B? Thanks.
