Yes, perhaps they want us to like Locke (besides Terry O'Quinn plays him brilliantly). And Sawyer is one of the most consistent characters and the one who' evolved more.

Yes, it could be purgatory, but for me it's an "easy solution" to the entire show, that or a dream. Iif it's one of those, I'll be disappointed because I'll think they were pulling our legs throughout the entire show (I'm already disappointed but perhaps if they made a stunning end, I'll change my mind )
