The vibe I got was that Sawyer was deffinitely setting up something in his head to get Hurley's money. As for the Kate, Jack, Sawyer plan, hmmmmm, I don't know. Seems too obvious to me. BUT, I said the same thing about Locke being Smokey back in S5. I totally didn't believe it, and now that we know it, I look the fool. Hmmmmmmmmm.
