Sign in to your ScreenRant account Lost easily ranks among the most influential network TV shows of the mid-2000s, and this was largely due to a perfect storm. Expertly placed cliffhangers and stunning plot revelations were timed to maximize audience intrigue. The time period when it arrived cannot be understated, either. Lost debuted in 2004, at a time when online discourse was burgeoning on social media. This led to a slew of folks discussing the show in status updates, posts, and widely disseminated articles, helping the series to pique the interests of more and more viewers. Ultimately, this snowballed into a mass online watercooler effect of sorts, where throngs of people eagerly anticipated the next out-of-left-field development Lost's writers' room would conjure up. While there's no shortage of surprising moments in the series, like Lost's mysterious polar bear, there is one scene that featured an iconic line that stands out as not only defining the series, but the long-form mystery genre as a whole. Jack’s Iconic Line In The Season 3 Finale Of Lost Changed Television From the start of the series, Lost's main characters had one mission: get off the island their plane crashed on. However, enigma after enigma almost made the prospect of them ever leaving the island seem impossible, at least not without some solid answers. So when Jack said, "We have to go back, Kate!" at the end of season 3, viewers who watched it live everywhere were enthralled. Indeed, there was no shortage of questions begging for answers queued up from the top of the season. Lost spent a lot of screen time revealing more about The Others, who turned out to be not as powerful or all-controlling as the survivors previously believed. At the season's onset, Jack, Kate, and Sawyer were captured by the group, who appeared to be another community of survivors. It didn't take long for the trio to be separated, leaving Sawyer and Kate to be forced into performing hard labor for the rival party. This led the two to engage in a physically intimate relationship. Meanwhile, Jack was paired with Juliet throughout season 3, who had feelings for the doctor, but they never came to fruition, despite the two sharing a kiss as they enacted their beach rescue mission in the finale. The real reason why Jack's "we have to go back" became such a slobber knocker of a line was because it entirely upended a major narrative through-line presented to audiences across Lost's first three seasons. Up until that point, each episode was littered with cutaways of what life was like off the island for each of the show's characters. This conditioned audiences to believe that they were learning more about the survivors' respective pasts as the series progressed. As it turned out, the opposite was true. These weren't flashbacks, but flash-forwards, meaning that each and every scene viewers were exposed to off the island took on a new interpretation. So when we see bearded Jack meet up with a mystery person he was obsessively calling all episode, and it turned out to be Kate, as he insisted on returning to the island, viewers were treated to a mental callback symphony. When Lost's "Through the Looking Glass" aired in 2007, it set a new standard for TV show twists, turning a cliffhanger into something much more significant. Not only did the series redefine the mystery genre with its flash-forward reveal, but Lost also put the mystery box genre back in the spotlight. Lost’s Biggest Twist Influenced Every Modern Mystery Box Series Due to the show's success, it's not surprising other series attempted to emulate the same mystery box formula. One of the more notable recent examples is John Griffin's From. Like Lost, the MGM+ series centers on a major mystery, featuring a slew of different characters from different walks of life who are stuck in a purgatory-like atmosphere from which there is no immediate route of escape. Also like the ABC smash success, From features mysterious creatures and loud, unnerving noises that call back to Lost's smoke creature. That's not where the similarities end, either. Remember the DHARMA hatches? From features characters exploring underground to inspect tunnels beneath homes, which seems reminiscent of Lost as well. And it's hard to ignore one of the most glaring visual cues that appears to be directly lifted from Lost's sixth season: a lighthouse in the middle of the forest — From has one too. Yellowjackets is also centered on a plane crash, and utilizes narrative time jumping in order to move its plot along, while answering questions along the way. Akin to Jacob's cabin in the ABC series, the Showtime thriller sports a recurring cryptic symbol that pops up throughout the show, much like DHARMA's presence. Then there's Manifest. Like Lost, it too features an airplane disaster along with a reality-bending anomaly affecting its cast. Oft-repeated numerology also plays a large part in Manifest, giving viewers a series of symbolic numbers to track, echoing Lost's predilection for turning its audience into active investigators. There's no question that modern mystery box shows like the ones mentioned above didn't look to Lost as the gold standard for building interwoven mysteries and mind-bending twists. Lost's "We Have To Go Back" Episode Also Featured Another Iconic Moment Via MovieStillsDB Charlie's self-sacrifice at the end of Lost season 3 hit hard. He used his dying moments to scribble a message on his hand, and it's a moment that has haunted viewers from the moment it was first aired. Upon learning there was a signal blocker preventing communication of survivors to the outside world, Charlie resolved to disable it. Subsequently, he swam down to The Looking Glass, a DHARMA station that was housed underwater. While he was able to disarm this frequency jammer, his correspondence with Penny revealed shocking information. It turned out she had no connection to Naomi, whom the survivors met previously. Not only did Penny have no idea who Naomi was, but she didn't send a rescue boat for those stranded on the island. After Mikhail Bakunin set off a grenade outside The Looking Glass window, Charlie had to think fast, so he secured himself inside the room away from Desmond to ensure his survival. With the water rising fast inside the room, Charlie grabbed a waterproof marker and scribbled a message on his hand: "Not Penny's boat." The weight of Charlie's sacrifice was monumental, since he alerted everyone that they weren't going to be rescued by the boat, but rather, the vessel carried an ominous threat instead. Yet again, Lost inverted viewer expectations colossally with the "Not Penny's Boat" reveal, in addition to Jack insisting to Kate that they needed to return to the island. It's tough to argue that the series ever regained the same mystery momentum it garnered throughout season 3, however. Afterward, its writers were criticized for attempting to craft more shocking twists and turns, arguably, at the sake of telling a compelling narrative. Instead of telling a great story, many viewers felt the series became obsessed with one-upping itself with how bizarre a premise it could conjure. In some ways, one could argue that these massive season 3 twists set Lost on a trajectory that cannibalized what made it such a fascinating watch in the first place. That said, watching these episodes in real time, week after week, witnessing the show's presumed narrative rhythms capsize in a way that prompted it as a whole to be re-evaluated, was a truly unprecedented spectacle. And there's no doubt that Lost's mystery box formula is something that other showrunners have been drawing inspiration from ever since.
