A Headmate with the role of an Interpreter benefits the system by being able to interpret the necessities of non-verbal or semi-verbal headmates. They can serve as Negotiators in situations where a headmate may be easily misinterpreted. It’s not uncommon for Interpreters to be limited in languages foreign of their own so they’ll either depend on body language or hold a strong enough bond to understand another headmate.
