Lost Pilot Script.

The writers reveal the characters by the way they talk by giving them a certain type of vocabulary. The main character Jack is seen as a very well educated person because of his knowledge and leadership skills during the chaos after the plane crash. Kate is shown as a shy woman who doesn't really trust others but will after she is given enough information. For example, when Jack asks her to help him she frowns upon her abilities at first and says she can't but eventually gets over it and helps him. Hurley looks like a young carefree guy who is not very educated and likes to help others. Boone seems like he wants to satisfy others and just be acknowledged. The difference between Jack and Hurley would be that Jack is well educated, fit, and a leader while Hurley is out of shape, not very smart and he abides by whatever he is told to do.
