For a solid year, I rewatched Lost in preparation of Season 6. I took thorough notes on each episode, keeping careful track of the show’s mysteries, and when and if they were explained. The remaining unanswered questions I present here are based on those notes.

Damon Lindelof and Carlton Cuse, the masterminds behind Lost, have made it clear that when it comes to wrapping up the show, their priority is the characters and their story arcs. All of the mythology stuff comes in a distant second. I wholeheartedly agree that the characters are what ultimately matter. But to satisfy my own kicks and curiosity, I just wanted to know what was left to be addressed.

My questions might be a little different than yours. That’s okay. Mine come from the perspective of a fiction writer who recognizes literary techniques and has a pretty good handle on how writers think and work. (But please don’t think I’m comparing myself to Lost’s writers — I’m in awe of what they’ve done with this show.)

Got a question to add to the list? Email me.

I present:

  • A downloadable PDF checklist of Unanswered Questions. This version groups the questions together by topic, and words them in a concise summary that takes everything known about the show into account. This list is by far the easiest to follow and understand.
  • The complete, unabridged list of unanswered questions I compiled when I rewatched all five seasons of Lost. It’s unordered, extensive, and not recommended for casual fans. That list is on this page you’re reading now; just scroll down.
  • What about the questions that are likely to go unanswered? Here are my best guesses as to which trivial mysteries just won’t be addressed.

Where is Christian’s body? Why wasn’t it in the coffin? [1.05]

According to psychic Richard Malkin, “danger surrounds” Claire’s baby, and the child requires her protection and influence. Why? What did he see in Claire’s reading? What was so dire about the child’s future that he would go to such great lengths as arranging for Claire to be on Oceanic 815 to ensure that she alone would raise the child? [1.10]

The conclusion we’re meant to make from the episode is that the Swan station went into lockdown mode based on the timing of the food drop. So… why? Why would the station need to be locked down when a food drop was being conducted? [2.17]

Locke suggested that the blast doors being triggered during the supply drop may have been intentional — to trap the Dharma workers in a place where they couldn’t see who was dropping it. Is this the reason for the lockdown? If so, why would the source of the food drop want to remain anonymous? [2.18]

Why does the man in the Dharma orientation videos go by different names in each one? [2.21]

Was Desmond’s chance encounter with Libby really so random? She was awfully trusting and willing to believe in a man she didn’t know. Was there more to this than it seems? [2.23]

What did Eko mean when he told Locke that the rest of them were “next”? Next at what? The next to die at the smoke monster’s hands? [3.05]

What became of Ben’s childhood friend Annie? Was she killed during the Purge, or had she left the island by then? [3.20]

How did Penny know about the island, and that Desmond was on it for three years? [4.05]

Why was the hidden door in Ben’s basement covered in hieroglyphs? [4.09]

Why has Widmore been having nightmares? [4.09]

Who was the man stationed outside of Santa Rosa Mental Institute, watching Hurley? Who did he work for? [4.14]

Charles Widmore knew of Paik Industries and even mentioned that he played golf regularly with Sun’s father. Are these two powerful men merely business associates, or do they share a deeper connection (such as an interest in the island, perhaps)? [4.14]

Why is it so cold down in the chamber where the island-moving wheel is housed? [4.14]

Why doesn’t Claire want Aaron brought back to the island? [4.14]

Since turning the wheel beneath the Orchid station sends one to the Tunisian desert, it stands to reason that the polar bear Charlotte found in Tunisia wearing a Dharma Initiative collar (in 4.02 “Confirmed Dead”) must also have turned the wheel at some point, and that’s how it wound up there. What and when were the circumstances surrounding the polar bear that turned the wheel and moved the island? Who was responsible for this, and why? [4.14]

Chang selected the site of the Orchid station, based on his knowledge of the pocket of “unlimited power” beneath the site. How did he know ahead of time where to build the Orchid? [5.01]

Who shot at the survivors from the second canoe? [5.04]

Who is the “very clever fellow,” working for the Initiative, who figured out how to find the island? [5.06]

If Abaddon’s the reason Locke went to Australia for his walkabout, and Abaddon works for Widmore… does this mean that Widmore knew Oceanic 815 was going to crash on the island, and he arranged for Locke to be on it? [5.07]

Since Amy was able to carry her baby to full term and deliver successfully (with Juliet’s Caesarian help), then the problem that present-day Others have with bearing children is something that began after 1977. What’s the cause of this childbirth problem in the present? [5.08]

How and when did the Others and the Dharma Initiative come to a Truce? What were the circumstances that spurred this agreement? [5.08]

Presumably, the Hydra Island runway was ordered built by Jacob, who knew that Ajira 316 would be coming to the island in 2007 and would need a place to land. So how did he know it would be coming? [5.09]

How did draining the water out of that tiny hole below Ben’s house summon the smoke monster? [5.12]

Is Pierre Chang really dead in the present? Did he die on the island? If so, how? [5.13]

Why was an enormous statue of an Egyptian fertility goddess (Tawaret) erected on the island? And what is the significance of Jacob living beneath it? [5.16]

What is Ilana’s history with Jacob? [5.16]

What happened to Ilana in the past, that gave her such a severe head wound? [5.16]

Why is the Man in Black “stuck” in John Locke’s form? Why can’t he change his appearance anymore? [6.04]

Is it coincidence that the numbers representing each of the remaining castaways on the cave wall correspond to the cursed Numbers? How long have these names been written here? [6.04]

Who really killed the remaining Ajira survivors? Was it Widmore and his people? The smoke monster? Someone else? [6.08]

Sideways reality: Why aren’t Sun and Jin married? [6.10]

Who was Mother? How did she get to the island? Did she have a predecessor as island protector, or was she the first? How did she know so much about the island and how it worked? [6.15]

The Light beneath the island is what makes the island so important and special. But what is the Light? [6.15]
