This time I have analyzed all the dialogues of the five seasons, but thanks to the scripts hosted in lostpedia.wikia.com we can know the words each character said… exactly.
In the image each character has his own words. The bigger the more times they used it. The distance to the character is mostly random. We choose nine of them… look at it and you will know why.
As a curiosity take a look to number of times each character talk, the number of words spoken and the average words per intervention.
