Is it just me or is Sawyer almost like the muscle of Locke's group, I can't put my finger on it, but he's leading too.

I think, in the long run, Locke's gonna be too interested in kissing the island's butt to serve as any kind of leader. I guess kinda in the same way as Ben -- though Ben's interests seem to be more self-serving than island-serving -- people will revolt against Locke as a leader if they realize that he'll sacrifice them in a heartbeat if the island (or Walt or Jacob or whoever the dead-dictator-of-the-day is) tells him to. Sawyer, at least, only kills bad guys and hasn't gone 'round the bend talking to ghosties and the sky. And he won't. In this leadership-race, I think Sawyer gets my vote! :)
