Austen creates characters in a variety of ways. For example, she mixes the narrator's and Elizabeth's opinions together. Because of this, we can learn Elizabeth's thoughts and feeling through the narrator and therefore learn about her and how she thinks, allowing us to make a judgement on her character.
Another way Austen creates her characters is by quickly changing subject from Mrs Hurst and Miss Bingley to Darcy when he enters the room. This shows the impressiveness of Darcy and his ability to shift attention to him when he enters a room, due to attention of the narrative shifting to him as soon as arrives.
Contrast is also used, with 'but' highlighting differences between Darcy, Mr Hurst and Bingley. 'But diffuseness and warmth remained for Bingley's salutation' shows that Bingley is warmer and friendlier than the other two men. This suggests that there isn't warmth in the other two men's greetings, and therefore that they are possibly putting on a fake personality for public gatherings, due to their greetings lacking warmth and therefore seeming ungenuine.
The omniscient, all knowing narrator tells us character's thoughts and motives that we would not usually know, gives us extra insight into their character. For example, 'Miss Bingley's attention was quite as much engaged in watching Mr Darcy's progress through his book, as in reading her own'. Without this information, we would presume she was just reading a book, just like Darcy. However, we learn that she is interested much more in Darcy and in trying to learn about him to try and form a relationship with him than actually reading the book she has in her hands.
Character interaction also contributes to the creation of characters. For example, when Darcy and Elizabeth are talking towards the end of the chapter, it doesn't say 'said' followed by the character's name who is speaking. This suggests the two characters are extremely engaged in their conversation and are close, therefore that there is intimacy between them and a relationship may soon blossom. A lack of replies in a conversation involving Miss Bingley, shown by 'no one made a reply', is another character interaction. This shows that the conversation lacks any interest from the participants, therefore suggesting that their topic conversation is not something that interests them and that they are putting on a false character in an attempt to impress someone, such as Miss Bingley trying to impress Darcy.
Self realisation from characters, namely Darcy, also creates character. Darcy 'began to feel the danger of paying Elizabeth too much attention' shows he has realised that he has feelings for Elizabeth, furthering his character and the story's progression. This way of creating character is combined with the omniscient narrator being able to get into character's heads and tell us what they are thinking.
