WWWWAAAAALLLLLLLT made a special return
Too bad he's a cocky-ass teenager now. I hope Vincent growls at him. Speaking of, where the hell is Vincent???
Can we confirm that the people who killed all the commandos and are following Locke now are the 'Others' who we always hear whispering in the jungle? You know the ones that we've only seen from the ankles down that tip-toe through the jungle? Or have we yet still to learn who those folks are?
The cold, icy place where Ben altered time/space by cranking the wheel was so cool.
And you know how Ben was telling Jack that the entire Oceanic 6 have to go with him (Jack) in order to get back to the island... well... is Ben telling him that because he wants to go back too? And if so, why would Ben need them in order to get back? It just seems out of place since Ben's arrival on the island was completely different from theirs. And wouldn't Desmond have to accompany them also?
I'm not sure if Jin is dead or not. I think he could've jumped or being thrown off the boat by the explosion without having been killed.
My theory about Locke is that
it is him in that coffin. And that he came back to the mainland to get Jack. Locke and Jack have always been depicted as opposing forces that balance one another. So my theory is that Jack's absense from the island disrupts the balance and causes trouble. Who knows what the trouble is? Maybe the smoke monster and the polar bears are on a rampage?
That would lead to the question of who the two people were that brought balance before Jack and Locke crashed there? Ben and someone? Maybe Whidmore? And then Whidmore left for some reason and was unable to find the island again?
And of course, when Season 5 premieres, we're all going to want to see how the people on the island are doing. Have the survivors joined Locke and his Others? I can't see Sawyer following Locke. Maybe Sawyer becomes the new leader of the remaining survivors?
