Sorry, it wouldn't let me reply to the original message for some reason, so here goes :

A few words on my top two : The big unanswered mystery about Lost for me is how anybody DIDN'T like Across the Sea! There were genuinely no unanswered questions left for me after this episode, it covered it all, and it covered it brilliantly. Anything left supposedly unexplained was rendered obsolete by the grander knowledge that we gained here.
To roughly quote Mother about the source 'It's life, death, rebirth.....there's a part of this inside every man....and if it goes out here, it goes out everywhere' What more powerful and telling a description of what the island is, and in terms than be easily grasped, were people hoping for?!
I loved discovering the origins of the wheel, and how it operates by harnessing the indescribable, limitless electromagnetic properties of the source.
I loved finding out that MIB became the Smoke Monster through the fusion of his human soul with the heart of this source, how much further could you really go in explaining the exact origins of such an entity?
And I thought it was fantastic that Adam & Eve were MIB and Mother, it simply had to be people of that massive stature in the island's history. Were people expecting the Degroots or Rose & Bernard?? Behave!
As for Live Together, Die Alone, all I can do is echo everything said earlier, a difficult choice but for me this is probably the absolute pinnacle. A masterpiece from start to finish, from Desmond's stellar flashbacks with Kelvin in the Swan, to seeing the others at their sinister, malevolent peak on that dock.
But the real highlight is what I think are the best 10 or so minutes of TV I've ever seen, from when Desmond realises he needs to push the button, and Locke subsequently breaks the computer, and the truly mindblowing scenes of the system failure and the discharge follow. Perfection!
