Mr. Rochester in the novel “Jane Eyre” by Charlotte Bronte is a man who is moody and stern at first, but he turns out to be a kind person. He represents a 'round character.'
Round characters are the characters who shows significant changes throughout the progression of a story. They are complex and undergoes development which at times surprises the readers. On the other hand, flat characters do not show any change and are basically two dimensional.
Bronte’s characterization in her novels reflected her analysis of the real-life characters. She doesn’t make Rochester a hero with good looks and very pleasant nature rather gave him the features which a man would possess in real. Every character in the novel had their own way of thoughts and perspectives which they do not want to compromise for any reason.
