I can't help but think that the vast majority of viewers (including here) are missing an amazing aspect of how the story of Lost is told. I see a lot of people complaining about how Ilana died, this week. In and of itself, Ilana's death was contrived and lame.
But her death was not a stand-alone thing. It is part of a huge story that has been carefully crafted and woven together since Season 1. They say history repeats itself, but on this island, this is true to the Nth degree. We are seeing the same situations and scenarios play out, over and over again. It mostly follows a patter of Season 6 mirroring Season 1..... and 5 mirroring 2 .... and 4 mirroring 3. So it is kind of like an A-B-C-C-B-A pattern. Mirror image. (Hence the mirror references in the final season, to draw attention to the idea of mirror-imaging.) The show has always been about duality -- black & white, free will & destiny, the Losties and vs Others, Locke vs Ben, the beach vs the jungle/cave, Jacob vs the MIB, and on and on and on. Even that stupid novel manuscript "bad twin." What a goofy form of foreshadowing that was... from Season 1 to Season 6, that is! Duality is at the heart of the design of the whole show, and the mirror-image structure of th! e storytelling is a major tool to demonstrate this in both obvious and subtle ways.
I could go on for pages and pages of examples of this phenomenon, and this is actually my single favorite aspect of the storytelling on the show! And Ilana's death is YET another example of this pattern. Her death replicates the death of Arzt in Season 1, and this is intentional, part of an intentional, grander and more intricate pattern. Here are a few other, quick examples:
Remember how Sayid was tied down on a table, electrical wires attached to him to shock him, in order to aquire information about him, in a dwelling place that is hidden within the jungle. This was carried out by someone who lost their child and doesn't know if they'll ever see their child again. This happened in Season 1 . . . and Season 6!
-------------------
SEASON 1 - While searching for answers to the island's mysteries, Jack is led by a mysterious man to find a cave, next to water. Inside is a black stone and a white stone, and various personal belongings, including a baseball bat. Alongside the cave is Charlie's guitar. Christian's body appears to have been removed. Jack almost fell off a cliff while searching for his father, and this led him to the cave. But, Locke reached out and took his hand and saved him.
SEASON 6 - While searching for answers to the island's mysteries, Sawyer is led by a mysterious man (FLocke) to a cave next to water. Inside is a black stone and a white stone, and various personal belongings, including a baseball glove. Just inside the cave is a lute (an ancient guitar). The name of Locke (who took Christian's place on Ajira 816) is removed, crossed out. Sawyer almost falls of a cliff while being taken to this cave, but FLocke reaches out and takes his hand and saves him.

SEASON 1 - Sayid is a man who is ashamed of his violent past, and of how certain authority figures pressed him into service to them, to hurt innocent people for his boss's gain. Sayid's leg is injured in the process of being caught in a trap. He is caught by the person who set the trap, Rousseau. He passes out, and she takes him to her hidden home, where she interrogates him about her child, which she says was kidnapped by the Others.
SEASON 6 - Jin is a man who is ashamed of his violent past, and of how certain authority figures pressed him into service to them, to hurt innocent people for his boss's gain. Jin's leg is injured when he is caught in a trap. He is caught by the person who set the trap, Claire. He passes out, and she takes him to her hidden home, where she interrogates someone else she captured along with Jin, asking him about her child, which she says was kidnapped by the Others.
----------------------
SEASON 1 - Hurley decides that everyone needs to know who each other is, so he starts a census, which leads him to getting the ship manifest with the list of all the survivors on it. Many of the names are crossed off, having been "eliminated" (by death) in the crash or immediately afterward. By going over the list, Hurley figures out that one of the survivors is not a survivor, but is really an outsider pretending to be one of them... someone who had already been on the island for a long time!
SEASON 6 - Hurley is used by Jacob to take Jack to the Lighthouse, where they find the mirrors and the giant dial with the names of all of the candidates written on it. Many of the names are crossed out, having been eliminated. Meanwhile, FLocke takes Sawyer (who in Season 1 had the manifest) to the cave by the sea, and also shows him the names of candidates. Many are crossed off. It is around this time that Sawyer also learns that Locke is not really Locke, at all. He is an outsider pretending to be a survivor... but is really someone who had already been on the island for a long time!
-----------------------
SEASON 2 - Desmond is waiting for his replacement, and uses a riddle as a password to determine whether a person is there to help with his mission. (What did one snowman say to the other snowman? "Smells like carrots.") Note: this riddle also appeared in Season 1, briefly, before Desmond ever appeared.
SEASON 5 - Ilana is searching for Jacob's replacement, and uses a riddle as a password to determine whether someone is involved in her mission. (What lies in the shadow of the statue? "He who will save us all.") Note: this riddle also appears in Season 6, thus mirroring Season 1, while 2 mirrors 5.
-----------------------
SEASON 2 - Jin appears to have been completely lost at sea, possibly dead, after the raft he's on is destroyed by an explosive. There is no sign of him. However, later, he is found on the island, having washed ashore there.
SEASON 5 - Jin appears to have been completely lost at sea, possibly dead, after the ship he's on is destroyed by an explosive. There is no sign of him. However, later, he is found on the island, having washed ashore there.

SEASON 5: A young Ben is shot by Sayid. Jack and others stand by and refuse to help Ben, but another survivor takes it upon herself to risk everything to rescue young Ben, even knowing he will be the leader of the Others and will be responsible for many terrible things.
------------------
SEASON 2: They found their way to the hatch. They argued over whether to do something (push the button) in the hatch. The season ended with a lot of arguing over whether to push the button, and finally they don't push the button, and BOOM!
SEASON 5: They found their way to (what would be) the hatch, where they argued over whether to use some modern technology (bomb) to counteract the island's dangerous "energy." And then "pushed the button" and blew it up (or more accurately, it imploded, just like the hatch did in Season 2).
(Note: "Pushing the button" is an old euphemism from the Cold War days that referred to dropping a nuclear weapon.)

. . .
One of my favorite (although more minor) examples is the "return" of Charlie's peanut butter, a couple episodes ago in Season 6. Remember Charlie's (imaginary) peanut butter, which he offered to Claire to try to lift her spirits in Season 1? Just recently, in the Smoking Club's camp, Sawyer came up next to Kate and offered her some "hot cocoa" to try to make her feel better. She asked where she found some hot cocoa on the island...? "I didn't," he said. "Just pretend." I had to laugh out loud at that one!
There are other examples I could cite. This is just a few, because the list is too long to post here, completely. But these show a clear and definite pattern. And Ilana's death is a part of that very intentional pattern. Yes, it's contrived... for a reason. Season 1 was giving us numerous pictures of what we would see in the final season! And Season 2 showed us many things we could expect to see in the next-to-last season, and so on! And I, for one, think it's awesome! On this island, history repeats itself... to the extreme. And no matter how much free will you try to exercise... this "curse" will catch up with you and make you a part of its mirror-image storytelling.
