Jack and Sawyer are opposites who slowly recognize themselves in each other. Jack is the good man who can't save everyone; Sawyer is the bad man who keeps choosing to do the right thing. The love triangle with Kate is the surface conflict, but the real tension is about identity: can a con man become a leader? Can a hero accept help? By Season 5, Sawyer has become "LaFleur" -- a better leader than Jack ever was. Their final interaction is mutual respect between two men who've earned it the hard way.
