Due to the fact that he has never spoken, lack of background information, and relatively short time on the show, very little is actually known about B. One thing that can be drawn for sure is that his intelligence level is through the roof, and his ingenuity has led to make many impressive creations throughout his short time on the show. He is able to make the best of any situation and overall is a very useful asset to one's team. He comes across as very relaxed in demeanor and proud of his smarts. The exact reason why B never speaks is currently unknown. On some occasions he has opened his mouth but gets cut off. It seems as if he is not totally opposed to it - he just prefers to stay quiet.
