You must watch this YouTube video. This guy is amazing with his “Lost” software how he explains the two parallel time lines exist. Then there is this “deleted scene” from Season Five where Faraday also explains the split in time.
So, we can see how the island is underwater in the “new” 2004 airplane scene. How? In 1977 Juliet detonated the bomb. The whole thing was gone and sunk the island (no, I don’t know how but come on, Locke turns into smoke so it’s possible here). Butterfly affect comes into play. Widmore has no reason to want to get back to the island (it’s underwater and everyone there is dead). Desmond never sets sail on his around the world trip and lands on the island. Ben and the Others back on the island never travel back and forth doing who knows what back on land. Juliet never goes to the island. Leonard would have never been chanting the numbers in the asylum for Hurley to use (yes, I know Hurley still won the lottery so it goes along with the theory that what must happen will happen).
In Season One people’s paths were crossing and it was fun to spot them but in Season Six their crossing paths now has a whole new significance.
If we believe the time line of Vaughn (the first video I linked) then the the two (or more) time lines will never cross. But if we listen to Faraday he doesn’t say they will cross either but he does reiterate that whatever happened, happened. On a side note, he says that he spent the 3 years back home recreating his all of his work back in Ann Arbor (if you recall that is where the DeGroots founded the Dharma Initiative) so in this alternative time line they have access to all of Faraday’s work. I can’t imagine what they might do with it in this alternative time line.
And let’s agree that Not-Locke was correct when he called their lives “pathetic” back home. As we can see from this first episode, they are no better off with the plane not crashing. Kate was better the original way because she didn’t have to go to prison and could stop running.
1. Remember right after Faraday talks to Desmond about finding his mother Desmond wakes up with Penny and suddenly “remembers” the conversation? When we first see Jack on the new plane he looks for a minute like he’s disoriented. I wonder if something similar happened to Jack in that we see him only moments in time after Juliet detonates the bomb. Hopefully you understand what I meant here. Not that she changed Jack’s present but it’s happening on two different plains of time simultaneously.

2. I don’t know if they were serious, but Darlton were recently on Jimmy Kimmel and indicated that the fact that the stewardess only gave Jack one drink instead of two was significant. But they joke a lot. Time will be the judge.
3. Darlton also told Kimmel that Rose being the confident flier while Jack was frightened has significance. I think it’s cute that Rose tells Bernard she missed him while he was in the bathroom. Or is there more to this as well.

4. How is it that Jack doesn’t remember cutting himself? And I love the scene here of Jack looking at himself in the mirror. Symbolic of the time lines.
5. If my theory is right then Jack would have never met Desmond in the stadium because Des would not have been preparing for his big sailing trip. Ever had dejavu? Jack is having it right here. Makes me wonder what my dejavu means. Hm…

6. Underwater shots. Here you go! Dharma security, Dharma houses, the swing set and even the Dharma shark!


7. One thing has stayed the same, opening the scene with an eye. But I have a hard time believing Kate could get her hands on false eyelashes. Maybe she took them out of Claire’s bag. Remember how Claire always had makeup on?

8. If Artz is asking Hurley to site lines from his Clucky commercial, then these teasers this summer really meant something; Clucky Commercial, Kate on America’s Most Wanted.
9. I still want to know how the Dharma van traveled with them through time.

10. Shouldn’t Rose and Bernard be in the current time with Jack and everyone? And are we going to see Vincent again soon?
11. Michael Emerson must be as excited at Terry O’Quinn for this season. Ben is now tied with Not-Locke and way far away from being any kind of leader. So his role and Not-Locke’s roll are going to reverse. I can’t wait to see how these two guys embrace these characters. You can see already the desperation in Ben’s face. But he always has a plan, right? Maybe Ben will be the one that saves them all. That would be ironic.

12. On a side note, are we going to find out anything about the “real” Henry Gale?
13. Here’s the shot of Not-Locke sitting in the old rocking chair. Looks like the chair from the cabin.

14. Wow, Not-Locke can repel bullets too.

15. Ash ring repels Smokey. This makes me wonder who exactly was in the cabin. We saw in the pilot episode (Season One) that the trees were being parted and the sounds of Smokey. But I also thought for awhile that Jacob had Smokey trapped in the cabin. Now I think that it really was Jacob in the cabin as it was surrounded by Ash. I think it was Locke who ended up breaking that ring and that is when Jacob retreated to the foot.

16. Locke had to die so that Smokey could take over his body. But there is more to Locke then just a vessel. Smokey also took over Eko’s brother, Christian and Ana Lucia so if that’s is all he needed then he could have killed Jacob before. He needed a true believer, like Locke. I wonder if Jacob also had Locke in mind for his own use? Remember how Richard came to him as boy with his “test” that Locke failed? They came to him again in high school.
17. I think we are going to hear the Juliet- coffee line again with Sawyer. I’ve said previously that I think she’s “mind” traveling between the time lines and that is how she knows the plan worked. Elizabeth Mitchell did say that she has more then one scene in Season Six. How the survivors will come to believe it is the next question. Maybe Juliet will somehow retain her memory from the island in the new time line. Maybe that is how Mrs. Hawkings knew to tell Desmond that he “had” to go to the island – she remembered or “mind traveled.”

18. Yeah Charlie! I really hope they bring him back more for this season. Charlie and Hurley were good friends so I can hope.

19. Looks like it’s still 2004 according to Sayid’s passport.

20. Guess we might find out why this watch was so vitally important to Jin. But all the money they find in his luggage makes me think that perhaps Jin was the one thinking of leaving Sun in this alternative world.

21. I don’t think that we discuss enough what a great job Josh Holloway does with his role as Sawyer either. We know what a great looking buy he is and to come onscreen with matted hair and all covered in dirt and blood, well he still looks good. But I think he’s really brought something extra to Sawyer last season and so far this season. I can’t wait to see how much he does this season too with the grief that Sawyer is going to be carrying.

22. I’m thinking that although the island is underwater in the new time line, someone (whether it be Jacob or Not-Locke) needed that body and that is where Christian is. I’m sure he’ll be popping up this season.
23. Nice of Kate to walk away with the torch right as Jin and Jack are going around the huge, gaping hole. But then she hears the whispers. I know that it appears that it’s the new Others but I’m not 100% sure of this. I could believe that they are talking in the cavern and the whispers echo, but it doesn’t explain how they traveled out in the jungle when the survivors heard them back in Season One. I’m hoping there is a little more clarity coming. Maybe all of the new Others at the Temple are dead or something like what Richard is? Afterall, they do have a ragtag group of people – ranging from a hippie to a Japanese Samurai dude.
24. More red flowers!

25. Here is the description of the new guy “Lennon” when they were looking to cast him. “According to the casting breakdown, Lennon is the scruffy, edgy and charismatic spokesperson and translator for the president of a foreign corporation who is far more powerful than it seems from his position.” Is the samurai guy president of a company back home? Did they change their minds about his role?

26. Jack didn’t care to know what the “risks” of putting Sayid in the water were because he’s not 100% a man of faith yet. Jack just thinks Sayid is all but dead anyway.
27. Non-Locke says he wants the one thing that Locke didn’t – to go home. Why does that have to mean off of the island? I think that the reason that the Temple Others got so upset knowing Jacob was dead was because the Temple is his “home.” And I would guess that he can do very bad things from “home” especially considering that they have the magic water at the Temple.
28. Jack tells Locke that nothing is irreversible. What if Locke does go to Jack and have his back fixed? Could Locke being fixed in this time line explain and carry over to another time line? Could it explain how Locke suddenly has the ability to walk once he’s on the island? I’m sure there is a subtle meaning to the line also but thought maybe there was a literal meaning as well.

29. Here’s a shot of Jack’s card, in case it means something later.

30. Right after Not-Locke knocks out Richard he says “I’m very disappointed in all of you.” Huh, why? the he slings Richard over his shoulder like an old boar. Maybe he’s going to hold him ransom to get inside the Temple?
31. I originally thought that Sayid was taken over by Jacob. But when asked, Darlton would only say that “something” is inhabiting Sayid. What are the possibilities? We may not know yet. After all, who could have ever dreamed that there would be a freighter appear or that only 6 would get home then come back. But I would still prefer that it’s Jacob.
