Lois: It'll be okay, Chris. Remember that episode of The Honeymooners when Ralph lost his job but at the end of the show he didn't get it back?
Peter: Oh yeah! What was up with that? That bugged the crap out of me.
When a Story Arc disappears off the face of the storyline without warning, never to be heard from again.
For a long while viewers will likely be under the impression that the disappeared major Plot Point will pop up any minute now — an impression which will eventually give way to a dawning comprehension that the story has moved on, none of the factors that made this plot point important matter any more and it would be just ridiculous for someone to suddenly recall the whole thing now, after all this time.
Why did this happen? It's anyone's guess, most of the time. Maybe the fans complained. Maybe a crucial cast member quit the show. Maybe the powers that be didn't like it. Maybe the writers just realized it was a lousy idea, cluttering up the plot, or just lost interest in it. This weighs rather heavily on the Willing Suspension of Disbelief, but sometimes the best way to execute an Author's Saving Throw and get rid of an element that isn't doing the story any favors is to just pretend it never happened. Then again, it's harder to pass the throw if the arc had significant buildup; such buildup retroactively becomes Fauxshadowing.
Mainly a series trope; writers will usually avoid this if they can, and you can always go back and edit a stand-alone work before publishing, unless the deadline is really pressing. At best, it's a gross violation of The Law of Conservation of Detail; at worst, this is done for no reason whatsoever and rends the plot asunder to create a fresh new Plot Hole.
Jokes tend to have this trope in spades, as the whole point is to build up to an unexpected pun or twist ending by any means necessary - then full stop, no closure. People who have No Sense of Humor (and people trolling) will then say "And then what happened?"
Cases where there is a resolution eventually, no matter how trite or sudden, aren't this trope — though really bad cases of Four Lines, All Waiting, Out of Focus or Sequel Gap usually end up emulating the effects for all intents and purposes; when the plot point does get brought out of cryogenic suspension, fans have long since lost all hope for it or interest in it.
Compare with: What Could Have Been, Kudzu Plot, The Chris Carter Effect, Creator Breakdown, Franchise Killer, What Happened to the Mouse?, and They Wasted a Perfectly Good Plot. See also: Dummied Out, Left Hanging, Cut Short and The Resolution Will Not Be Televised.

- In as much as there is continuity, one Dilbert comic involved Dogbert raising an army of cloned vegetables. It was supposed to be longer, but Scott Adams found it wasn't as funny as he thought it would be, so he actually stated in comic he was ending the arc by "skipping ahead to the big finish." Another arc, featuring the death of Dilbert, was also resolved quicker than planned when Adams ran out of ideas (he also mentioned doing it to shake things up, but the strip was so early that nobody cared). Another early arc involved Dilbert building a robot that became gradually more intelligent before being dropped without comment a few weeks later; the plotline was revisited more than a decade later with a different robot, who went on to become a regular.
- A two-week 1995 FoxTrot storyline had Paige getting the role of Cleopatra in the school's Antony and Cleopatra play, (with Morton playing Antony). The story ended before the play started, with Roger noticing Paige's name in the play program. After that strip, the story suddenly ended, with no actual strips of the play being performed, and the story was never mentioned again.
- At one point creator Greg Evans had planned a storyline which revealed the reason Satellite Love Interest Aaron Hill was so uninterested in Luann's (or anyone else's) advances: he simply wasn't interested... in girls. Evans got cold feet, fearing he didn't have enough of a subscriber base to absorb the potential loss of paper slots, like Lynn Johnston did when she pulled a similar storyline. So he altered the story so that Aaron was hiding a relationship with the much older Dianne.
- After Aaron was put on a plane to Hawaii, the strip signaled his reunion with Luann in a storyline where she wins a contest flight to Hawaii. What happens when she reunites with Aaron there? She sees him once with another girl, doesn't even bother to confirm she's his girlfriend, and then doesn't speak to him again after that. Aaron's return was teased again with a strip where he sends Luann a Myspace friend request and a message suggesting he's single now, but nothing came of it after that.
- Doonesbury decided to celebrate its 20th anniversary year (1990) with a big epic storyline in which all the strip's various plotlines and characters converged together, with practically the entire cast all ending up at Mike's apartment. Creator Garry Trudeau ended up writing himself into a corner with the arc, which had everyone together but didn't give them anything to do. The arc got weirder when Mike's house was mistaken for a crack den and raided by federal agents. Trudeau decided the whole thing had gotten out of hand, and undid the entire arc by revealing that the last several months worth of strips had been All Just a Dream.
- Heart of the City story arcs often end suddenly with no further explanation. An example is an arc where Heart's mom agrees to go on a date, which Heart dreads until she learns that the man is a talent agent. After that, the arc ended.
- Lampshaded in a Peanuts strip in which Snoopy is writing a novel. One part of the plot involves a king living in luxury while his people starved. In tying up the plot threads, Snoopy left him out.
- The release of the album "Fangs!" seemed to be something of a new beginning for the experimental rock band Falling Up. It was both a New Sound Album and a Concept Album that was the beginning of a story arc... then the band broke up. The band reunited in 2011, but their album doesn't really continue the story line of Fangs.
- David Bowie's 1995 concept album 1. Outside was supposed to be the first of a series leading up to the millennium. However, further albums continuing the "non-linear gothic drama hyper cycle" never appeared. Almost 15 years on (and with its artist dead) it's probably safe to classify this as an aborted arc.
- Sufjan Stevens has discontinued his "50 states project", which started with Michigan and Illinois. Looks like there won't be any more.
- John Linnell intended his 1999 album "State Songs" to be the first part of a trilogy... which has never been continued, and probably never will be. This album was recorded during They Might Be Giants' 1996-1999 downtime (their only studio album of this period - "Long Tall Weekend" - consisting largely of old, unreleased material), and since then, the group have been much, much busier. The idea of the "State Songs" project was to record fifty songs titled after each of the U.S. States, but he only got to sixteen of them note
- The Beatles had planned to record an theme album about their childhoods with "Strawberry Fields Forever" and "Penny Lane" being the first two songs written for this endeavor. "When I'm Sixty-Four" was the next song recorded for the album, though it had been written years earlier, and eventually the concept shifted to a fictitious band putting on a performance, yet with every song being impossible to do live (for them at the time) and thus Sgt. Pepper's Lonely Hearts Club Band was born. While the title song and its "reprise" relate to this theme, none of the other songs do.
- In 1969, the band decided to record some songs together in a studio, and later in an impromptu concert on the Apple rooftop, in what would become the album Get Back, all while filming a documentary about the experience. The Glory Days revival would even be illustrated with an album cover replicating the Please Please Me one. The whole ordeal wound up just raising tensions and ultimately leading to the Beatles' breakup, but not before they decided to make Abbey Road before calling it quits. Then the Get Back sessions were submitted to Phil Spector for an orchestral makeover, and the result was Let It Be. (The cover was famously repurposed for the compilation 1966-1970, aka The Blue Album.)
- Vampire: The Masquerade had innumerable half-finished non-runners, especially when it came to details like the end of the world. Most notable was the pathetic Rasputin plotline, wherein Rasputin the Mad Monk was actually a Tremere who had somehow found a way to essentially become Caine, so that God/Karma could kill him instead, thus averting complete obliteration of the vampire species.
- In truth, many Old World of Darkness splats laid claim to Rasputin, not just the vampires. The one that stuck? He's a wraithly Puppeteer who enjoys bodyhopping various supernaturals.
- Vampire: The Requiem has a lot of potential aborted arcs. The possibility that Anoushka (Vlad Dracula's childe) is The Unholy (superpowered urban legend force of nature) is toyed with again and again, and finally thrown away in the Immortal Sinners supplement. Thankfully, the in-character artifact clanbooks allowed the various freelance writers to wrap up their pet storylines, with the unfortunate side effect of so many of those favorite storylines being given pat Word of God bullshit tie-ups to shut the fans up.
- The "Glass Armonium" MacGuffin shut down many plot hooks.
- The prerevision Magic: The Gathering comics were leading up to the Planeswalker War, but the comic line was cancelled before it could be published. Some of the characters involved, like Freyalise, Taysir and Tevesh Szat have turned up later in modern storylines, but details on what actually went down are extraordinarily vague.
- Warhammer 40,000:
- The game is infamous for its plot never advancing. Almost all major events or story lines that might have an actual impact on the larger universe are almost never brought up or touched upon after the expansion in which they take place.
- The "Eye of Terror" summer event from 2003 was billed as having a huge impact on the 40k universe - if the Imperium and their allies won, the Eye of Terror would shrink, the Imperium could expand to entirely new sectors of space, and an upswing of faith could generate new crusades and a (relative) golden age for mankind. On the other hand, a victory for Chaos would hasten the Imperium's collapse, see increased Chaos incursions, and possibly even lead to the fall of the Cadian Gate and a huge resultant tide of Chaos Marines and daemons into realspace. It had the potential to introduce enormous changes to the setting and there were even rumours that significant characters from the losing side could be killed. However, none of this panned out - once the results were in and announced (a minor victory for Chaos - stated in-game to be Abaddon succeeding in gaining a foothold on Cadia, albeit with his fleet in tatters), Games Workshop did absolutely nothing with it before quietly sweeping the whole thing under the rug with a series of retcons a decade later.
- As of 8th edition in 2017 (said event occurred shortly before the release of 4th edition), status quo has finally been dumped and nearly everything promised back then has actually happened; the Cadian Gate has fallen and Chaos has spread across large parts of realspace, splitting the galaxy in half. Of course, this more than likely brings a couple of decades or so of the new status quo.
- Games Workshop had reportedly planned an arc that would see the Tau raised as the chosen race to defeat Chaos, with the Ultramarines discovering this fact and opting to ally with them, possibly against other elements of the Imperium. The Tau were even flagged as "Battle Brothers" for Space Marines in the 6th Edition rulebook (the highest tier of alliance, indicating deeply trusted allies). However, possibly in reaction to the negative reception this idea received, the idea was quietly shelved and the Tau-Space Marine alliance capability was reduced in future editions.
- Shadowrun does this on purpose, allowing game masters to run self-written adventures that "fill in the blanks" and tie-into the game's lore.
- The American version of Kristina från Duvemåla cuts out the significant plot point of the majority of the immigrants being killed in a Sioux attack after Kristina's miscarriage. (Presumably for the sake of political correctness, since the songs are left in their full length but with different lyrics, thus saving no time.) However, the event is still foreshadowed in "Queen of the Prairie"/"Wild Grass" through the fur trader's warnings, leaving it as an unresolved thread to audiences unfamiliar with the original story.
- The Taming of the Shrew begins with the premise that the play is a play within a play being presented to a drunkard named Christopher Sly, who is being fooled into thinking he is actually a rich and prestigious man as a prank. After the initial set-up, this is never brought up again. Some adaptations bring back Sly in an epilogue.
- Rosmersholm, written by Creator/Henrik Ibsen in 1886, has an interesting set-up. It begins with a rather political premise, setting up the strife of the times, with the main character positioning himself in the middle. Then the play turns around and gets more and more introverted, putting politics firmly in the background, to focus mainly on the inner struggles of the main character. This can be seen from the beginning of the second act.
- Sometimes, at Disney Theme Parks, Imagineers will add something to an attraction while it's being built for some purpose, only to eventually go in a different direction, leaving an element in the attraction that leads nowhere. These are also a form of Dummied Out. Some examples:
- The nods to dragons and unicorns in Animal Kingdom were hinting towards a land that they ended up never building, Beastly Kingdom, focusing on fantasy creatures. The only things left of that (so far) are a dragon-shaped rock formation near Camp Minnie Mickey, a bridge that looks like the entrance to a castle, and the big dragon who appears on the park's logo to the confusion of many a guest. The concept of including mythological creatures into the park was eventually picked up by Expedition Everest's Yeti, but has yet to be paid off in full.
- The animatronic raven in The Haunted Mansion was originally going to be the "narrator" of the ride, which ended up being much better implemented with the "Ghost Host" being piped in through the Doom Buggy's individual speakers. The ravens, however, are still situated throughout the ride, flapping and moving their beaks as if they were saying something.
- In the super-secret-invite-only Club 33 restaurant, several disused animatronic animal heads hang from the wall. Walt had planned to be able to speak through them to his guests. The idea was abandoned because it was deemed too silly for a high-class restaurant, and because of privacy concerns. The idea sort of came to fruition at the shut-down Adventurers' Club in Disney World's Pleasure Island.
- The original vision for EPCOT was an aborted arc. Disney's plan was for an actual city (Experimental Prototype Community Of Tomorrow) where people lived and worked. The Monorails and the People Movers were to be part of the infrastructure.
- The anime prologue of Phoenix Wright: Ace Attorney – Spirit of Justice features Maya being attacked by a rebel in Khura'in in the middle of a phone conversation with Phoenix. Her mobile phone is broken, and Phoenix thinks something bad has happened to her. Not actually, because Nahyuta Sahdmadhi happened to drop by and immobilize the rebel before he could do any harm to her, but Phoenix decides to go immediately to Khura'in to check up on Maya.
In the game proper, this assault is never talked about. It's said that Phoenix just went there because Maya was finishing her training to be the Master of Kurain Village.
- In the first episode of Camp Camp, Max is trying to escape Camp Campbell and drags his new friends Nikki and Neil with him. After his plan inevitably fails, he swears to the councilor David that he and his new friends will escape, setting up the main plot of the series... which is dropped after being brought up again in only one episode. Though this may be justified, as in said episode, Max realizes that his problem isn't that he hates the camp... it's that he hates everyone.
