A couple of things...SPOILER...don't read this post if you didn't see tonight's episode.
I wasn't sad when Jin, Sun, and Sayid died, because they will all probably be okay when the parallel universes combine at the end.
Second of all, I have a question. Do you all think that Anthony Cooper, who is a vegetable in the parallel universe, was a good guy and loved John Locke, OR...was he in the middle of his attempt of conning John Locke to get his kidney when the plane accident that Locke talked about tonight happened?
Just a couple of things to think about.
