Does the character have any habits or nervous tics the reader should know about?
Nervous habits can give the reader insight into the character. For example, she might bite her nails when she’s nervous or wring her hands when she is uncomfortable. Does the character have an accent or regional dialect? This should be reflected in the speech pattern. A wealthy character living in the southern United States would speak differently than an indigent character living in New York. They would have different speech patterns and use different slang terms.
