I'm not sure what you mean by that (I honestly cant remember season one!). How was the coffin on the plane in season 1 if he was going to australia to get it? He hadn't picked it up yet. (again, sorry if I'm making no sense. I think I need to rewatch season one)
The flight sequences are all taking place on the way back to Los Angeles, but in Season 1 the flight crashed on the way to Australia (not on the way back).
Some questions I got from the episode:
- Why is the island underwater in the alternate dimension?
- Why does hurly say he is so lucky in the alternate dimension (AD)?
- How did Juliet die? Why did the rest live?
- What was in Charlie's mouth when he was trying to kill himself?
- Who is this new tribe? And how have they been on the island this whole time and remained undiscovered?
- Why does Jin have a bunch of money in AD?
- What does Fake John lock mean when he tells richard he is free of the chains?
Questions Answered:
- Fake John Locke is Jacob's enemy (I think this was revealed at the end of season 5).
- Fake John Locke (Jacob's Enemy - name tbd) is the Smoke Monster.
- There is white ash (or brown) around Jacob's Cabin to protect him for his enemy.
- Jacob is actually a good guy... at least it appears that way.
Um...watch season 1 again. They were definitely going from Australia to LA.
And to answer some of your questions:
- Why is the island underwater in the alternate dimension?
A: Who knows? They sunk it with the bomb in the alternate reality?
- Why does hurly say he is so lucky in the alternate dimension (AD)?
A: Because the island is gone, the numbers don't exist and his luck has reversed. But this poses the question: how did he win the lottery without the numbers?
- How did Juliet die? Why did the rest live?
A: She fell in a well and sustained injuries. Had the bomb gone off when Jack threw it in, before she got sucked in, she probably would have been fine.
- What was in Charlie's mouth when he was trying to kill himself?
A: Heroin. He was an addict in season 1.
- Who is this new tribe? And how have they been on the island this whole time and remained undiscovered?
A: They're a faction of the Others. I'm going on a limb and guessing that the Others split off after Ben's coup in the 80s and half of them stayed in the Temple to protect its secrets (and was also guarded by the Smoke monster which I suppose is now free after Jacob is dead) and the other half took over the Dharma initiative to conduct their fertility experiments.
- Why does Jin have a bunch of money in AD?
A: He was doing shady business for his wife's father.
- What does Fake John lock mean when he tells richard he is free of the chains?
A: I guess we'll find out! I am guessing that Jacob forced Fack John/Smoke Monster to guard the temple and the island even though he wanted to go home. Richard could also have been forced to stay on the Island to protect it. Again, I'm just guessing.
