the other castaways look to them as the leaders, if something needs to be done, they are the ones that the other castaways go to. Hugo is sort of middle management or union boss, he is in between. Sawyer is office supply, you don't like asking for stuff but you have to and he is questions actions. Kate is a lot like Hugo. Locke and Eko are not really trusted and seem to go their own way, and I think can be made to see the 'path' the others follow. Sayhid mostly defers to Jack but he follows orders and has been show to be flexable in the path of greater good (this may be known from back story).Brown Jenkin said:But Jack, Sawyer and Kate are equally isolated from everyone else. Jack leads occaisionally but for the most part he is the doctor. He has been just as likely to wander off with delusions or hide out in the hatch. Sawyer on the other hand is the complete opposite of a leader. After all his lying, stealing, hoarding and the gun incident who in thier right mind would follow (oh wait, these are the moronic lostaways). Kate has never really demonstated leadership either, she just seems to want to tag along with her "boyfriends". No I still haven't come up with any grouping that fits these 4.
If looked at as a business model, you replace management and your workers continue to do what they do. If it was one of those personality/management test, I think you would see that those four score high, being red and blues, if I remember the colors right.
