Okay, let me clarify some things. 

-His voice manipulation is NOT in fact really coming from the person's mouth. he is just making it SOUND like it is. The person may or may not be actually speaking at the time but he can make it sound like they are.

-I thought that our magic had to be something relating to our spirit and since my spirit was an air element, I thought Josiah needed to have an air power. Apparently I was mistaken. I suppose I will either just scratch that power or some up with a more cohesive one. I definitely want to keep the voice mimicry though. Would wind negation work?

-Third and seemingly most importantly, let me clarify his personality. Like any other human, he has predominant personality traits that are present most of the time. In normal situations with other people he knows or strangers who do not approach him, he is calm, cool and collected with a very polite air surrounding him. However, in a situation that makes him uncomfortable, such as someone asking him about his past, questioning his sanity, or confronting him physically, he may become paranoid and show physical signs of discomfort such as sweating or stuttering. 

Let me know if this answers your questions or if you would like more information.
