Lost took the Easter-egg enigmas of shows like Twin Peaks and The Prisoner to the next level. J.J. Abrams pioneered what is now known as “mystery box” storytelling when he filled the island with polar bears and smoke monsters and left his audience to wonder. Some Lost fans were disappointed by the ending, but the series was an undeniably wild ride. Even if you weren’t satisfied with the answers, there were plenty of shocking twists and turns along the way. 8 The Others Aren't Primitive When the plane first crashed on the island, the survivors assumed they were alone. Then, they were shocked to find that the island was already populated with people, dubbed “The Others,” and we were led to believe that the Others were a primitive culture living off the natural resources of the land like Jack and his group. So, it was pretty mind-blowing to see the opening of season 3, in which we see that the Others aren’t primitive at all. We start on Juliet in her house, then follow her outside to a thriving sun-soaked community, and then we see the Oceanic flight go down. This is the island, and these are the Others. They’re not violent savages; they’re just regular people, with houses and morning routines and book clubs. 7 Michael Kills Ana Lucia & Libby The season 2 episode “Two for the Road” starts off with one of Lost’s sweetest storylines and ends with one of its darkest twists. As Hurley prepares a romantic picnic for himself and his love interest Libby, he realizes he’s forgotten a blanket, and Libby heads to the hatch to get one. But as she’s walking in, Michael is talking to Ana Lucia about “Henry Gale,” their prisoner who will later turn out to be Ben Linus, the leader of the Others. Ana Lucia can’t bring herself to shoot Henry, so Michael offers to do it. But as soon as he has the gun in his hands, Michael kills Ana Lucia, and when Libby comes in to get the blanket, he shoots her, too. The best twists don’t just shock you; they intrigue you, and leave you with questions you can’t wait to have answered. In this case, the question is: what exactly did the Others do to Michael to make him this desperate? 6 Locke Is The Man In Black All throughout the fifth season of Lost, we’re led to believe that Locke has somehow cheated death, and that the island has magically brought him back to life. But he’s not quite acting like himself, and that should’ve been our first clue. Eventually, we learned that Locke was still dead, and that his body had simply been inhabited by “The Man in Black.” It was pretty heartbreaking to see such a kind, compassionate character get embodied by such a despicable force of evil. 5 Ethan Isn't On The Manifest In order to make himself useful, Hurley gets a hold of the manifest and starts interviewing all the survivors. It’s basically a makeshift census to gather data on everyone on the island. At first, it doesn’t seem like a particularly exciting storyline — it’s just low-stakes busywork to give Hurley something to do — but it builds to one of Lost’s greatest twists. As he examines the names on the manifest, Hurley finds that one of the survivors in their group, Ethan Rom, wasn’t on the plane; he was already on the island, and he infiltrated their ranks to compile a list of survivors for the Others. When he’s found out, Ethan goes on a rampage, attacking Charlie, kidnapping Claire for scientific research, and finally revealing his true colors. Ethan never seemed 100% trustworthy, so it was hardly surprising that he had a nefarious ulterior motive, but the revelation that there were already people on the island before the crash was a huge deal. 4 There's A Guy Living In The Hatch Midway through Lost’s first season, Jack and the gang discovered a hatch in the middle of the jungle. They couldn’t open it, but they wanted to know what was inside, so they spent the rest of the season trying to blow a hole in the hatch. In the finale, they finally did it, and in the season 2 premiere, we saw what was inside. Set to the sounds of “Make Your Own Kind of Music” by Mama Cass, we see Desmond wake up, go through his daily routine, and punch a code into an old-timey computer before being interrupted by an explosion. As he looks up through the smoke, he sees Jack and Locke breaking into the hatch. This was a perfect way to reintroduce us to the world of Lost, and the smartest way to show us around the hatch. 3 Season 3's Flashbacks Are Really Flashforwards By the time Lost reached its season 3 finale, “Through the Looking Glass,” the format was well-established: each episode is split between present-day action on the island, and a flashback storyline filling in a key chapter of the central character’s past. But the season 3 finale mixed it up a bit. Throughout the episode, we see pretty familiar flashes to Jack, bearded and depressed, addicted to pills, grieving the death of an old acquaintance. At first, it seems like we’re just seeing one of the darker days from Jack’s past, but then Kate shows up. These aren’t flashbacks; they’re flashforwards. Jack keeps telling Kate, “We have to go back!” So, at some point in the future, Jack, Kate, and maybe some of the other survivors will make it off the island, and something will draw Jack back to its shores. It was an awesome way to end the season, and a great way to build anticipation for season 4. 2 Not Penny's Boat The flashforward revelation wasn’t the only jaw-dropping twist in Lost’s season 3 finale. The episode’s present-day action sees Charlie and Desmond trying to get in touch with Desmond’s girlfriend Penny, who Naomi claims has sent her from a nearby freighter. However, after getting onto a video call with Penny, Charlie is shocked to learn that Penny doesn’t know Naomi, and that’s not her boat. After Mikhail floods the communications room with a grenade, Charlie locks the door to save Desmond. Just before he drowns, Charlie manages to write, “NOT PENNY’S BOAT,” on his hand, warning Desmond about the freighter fakeout. Charlie wasn’t always perfect, but he did try to become a better person during his time on the island, and this final sacrifice was a suitably heroic sendoff. 1 John Locke Is In The Coffin In Lost’s season 4 finale, “There’s No Place Like Home,” we finally got to see who Jack was grieving in the season 3 finale. Season 3’s secret flashforwards had shown Jack mourning a man’s death, and season 4 identified that man as Jeremy Bentham. Jack, Kate, and Walt all recount experiences where they were approached by Bentham, but we as an audience still don’t know who this guy is, and why he’s so important. And then, at the very end of the episode, the camera finally pans over to reveal who’s in that coffin: John Locke. Suddenly, it makes sense why everyone was so broken up by his loss, and why Jack is so eager to get back to the island and set everything right. Lost had a lot of surprising twists and turns throughout its run, but none of them hit quite as hard as the revelation that our beloved Locke was lying in a box.
