I thought the guy (Cooper) just conned Locke into believing he was his father and that was how he conned him into giving him the kidney - is that not right? I know for a fact he conned him into giving it to him, and I'm pretty sure he wasn't his "real" father, because seems like I remember him telling Locke "You needed a father figure, I needed a kidney". Am I remembering that wrong? Probably not gonna matter much in the end, but that's how I remember it. Are you saying the guy Sawyer killed was NOT Cooper?? Unless I missed something, it was the same guy who conned Locke that he killed, and Locke got him to do it because he (Locke) didn't have the stomach for it.
