9[[AC:{{Crossover}}s]]
10* ''Fanfic/ChildOfTheStorm'' has quite a few, to put it mildly.
11** Draco Malfoy's sudden change in attitude? It's because of [[spoiler:a voice in his head]] that doesn't appear on-screen past chapter 3, being mentioned once in chapter 21, and that's about it. Then it pops up again when chapter 7 of the sequel, ''Ghosts of the Past,'' is posted ''four years later.'' Harry, Carol and Jean-Paul figure out that there's something up and make a good stab at what it is.
12** The Shadow Initiative, mentioned once, in passing, in chapter 14. It crops up again in chapter 75, as a key part of Fury's counter-strategy to HYDRA.
13** Mentions of Harry's association with fire and affinity for phoenix feathers and other Phoenix related artefacts, as well as the fact that he takes very heavily after his mother in personality, turn out to foreshadow that [[spoiler:Lily merged with the Phoenix]] and the protection on Harry comes from the entity in question.
14** Harry's blessing from Wanda is mentioned a couple of times as warping reality around him ever so slightly, to ensure that he'll always have back up. Strange explains in chapter 48 that it was intended to help Harry through the trials to come. In chapter 77, however, it's revealed that it's also [[spoiler:part of his plan to defeat Chthon, as once the Darkhold is unleashed, circumstances and that blessing make Harry 'the fulcrum on which all worlds turn', making him uniquely able to undo what Chthon has done]].
15** On a lighter note, Odin's phoenix feather, which alludes to Harry's connection to the Phoenix, pops up again in chapter 79, when Odin has it covered in gold and gives it to Harry, who wears it constantly afterwards. In ''Ghosts of the Past'', it gains a more serious significance when [[spoiler: Maddie/Rachel]] feels an affinity to it and pinches it, whereupon it starts heating up. She later uses it [[spoiler:to hide and protect Harry's mind]] and it's revealed to have originally been [[spoiler:Laevateinn, the wand of Prospero Slytherin]].
16** Trelawney's Tarot reading in chapter 66 is littered with examples of this trope, with every single one of the ten cards pointing to something that will happen. By chapter 7 of ''Ghosts of the Past'', all of them except possibly 'Justice' and an aspect of 'the Star' have come to pass.
17** Harry's letter from the future has a few, though mostly of lighter things -- [[spoiler:Pepper's pregnancy]], for instance - and is quite vague since it's designed to avoid a paradox. However, Fury manages to deduce the existence of [[spoiler:Maddie Pryor/Rachel Grey]] from it, with the resultant OhCrap reaction.
18** Trelawney's second prophecy, rather altered from canon, is littered with them, directly (if obscurely, through metaphor) referencing Voldemort, Selene, [[spoiler:Clark Kent]], [[spoiler:Maddie Pryor/Rachel Grey]], the Red Room, Doctor Nathaniel Essex a.k.a. Sinister, Dracula, and possibly [[spoiler:the Dark Phoenix]]. There are others, which, for now, remain unrevealed.
19* ''Fanfic/EquestriaGirlsAFairlyOddFriendship'':
20** Timmy's Dad's sound-cancelling earplugs. [[spoiler:Timmy uses them to avoid getting brainwashed a second time by the Dazzlings.]]
21** The various bits of learning Timmy gets from each of the Rainbooms comes in handy when [[spoiler:he's using those skills to fight the Dazzlings]].
22* ''Fanfic/{{Empathy}}'' turns [[WesternAnimation/BigHero6 Baymax's]] defibrillator hands into this, as he actually puts them to use during the climax to end his fight with [[spoiler:[[WesternAnimation/Home2015 the Gorg]]]], shocking his opponent into submission.
23* ''Fanfic/FalloutEquestria'': [[RecursiveFanfiction Murky Number Seven]] has an example with an actual gun. Glimmerlight complains that the gun she gets doesn't even have a safety, to which the armorer is less than impressed. So later when a villain tries to [[NotWithTheSafetyOnYouWont mess with her gun's safety mid-battle]]...
24--> '''Mosin/Glimmerlight:''' Is not safe. Is gun.
25* ''Fanfic/FantasyOfUtterRidiculousness'': Marisa Kirisame's size-changing powder. At first it only turned fairies into suitable punching bags for [[WesternAnimation/MegasXLR Megas]]. Later, it's used to scale up Yuuka and provide her the means to fight Megas on even terms.
26* In the Gregg Landsman fanfic ''Fanfic/GloriousShotgunPrincess'', it is used as early as chapter 4, when Kasumi Goto steals a Honey Badger from the San Diego Zoo, names it Checkov, as a direct invoking of the trope. In Chapter eleven, the honey badger turns back up as the final bit to Hock's HumiliationConga.
27* ''Fanfic/HarbingerFinmonster'' (''WesternAnimation/DannyPhantom'', ''WesternAnimation/GravityFalls'', ''WesternAnimation/ParaNorman''): Tucker briefly manages to stun the lunch lady ghost with the stun gun Neil brought.
28* ''Fanfic/JusticeLeagueOfTheRebellion'':
29** After [[Anime/CodeGeass Kallen]] is selected as the Champion of Shazam, a green-cloaked figure (AKA the Spectre) tells the Wizard that she is best choice. He later returns to help Batman [[spoiler:control and channel the Seven Deadly Sins to fight Mr. Mind, and he later tells Kallen that Spectre's current host is her dead brother Naoto]].
30** The Wizard also tells Kallen that her new power can be shared to those she considered family. In the League's fight against the Seven Deadly Sins, she grants her power to the members of her rebel cell, the group she considered family after her brother's death.
31** [[Anime/CodeGeass Suzaku]], after escaping his execution thanks to Batman/Lelouch, uses his [[ComicBook/GreenLantern Green Lantern Ring]] to disguise himself as a blonde Britannian student named [[ComicBook/GreenLantern1941 Alan Scott]]. What seems to be a MythologyGag turns out to be a subconscious recollection of the ring's previous user: Alan Scott of the [[PrecursorHeroes Justice Society of Britannia]].
32* The ''Fanfic/JWITCHSeries'':
33** While fighting Phobos in "The Labyrinth", Will cuts off some of his hair. Said hair is used in a failed attempt to locate Phobos' sister, and it's later run through a DNA test that confirms Elyon to be Phobos' sister.
34** "A Dramatic Ambush" reveals that the Heart of Kandrakar was used by Lo Pei to seal Shendu in stone. In "A New Dawn", [[spoiler:this happens again after his resurrection]].
35* In ''Fanfic/KyonBigDamnHero'', Nagato checks Kyon's wristwatch in one chapter. [[spoiler:Later on, it saves his life when he gets shot, turning into an armour... skinsuit... thing.]]
36* ''Fanfic/{{Mad World|InvaderZim}}'' has the Residue Filtration System contained within Irken [=PAKs=], which protect them from the psychic residue which is gathered by the Wastelocks, and disperses it in such a way that the Wastelocks themselves can't properly form. [[spoiler:During the climax, Dib repairs Zim's, and uses it to weaken and drive back [[EldritchAbomination the Thing]].]]
37* ''Fanfic/MikePines'': When doing the Unicorn spell around the shack, Mabel expresses worry that, due to Mike's status as a zombie, he won't be able to enter the shack. Ford assures her that the magic will only keep out evildoers, which Mike confirms when he is able to walk through forcefield. [[spoiler:Mike ends up using this fact to expel Molten Freddy from his body, as while ''he'' can enter the forcefield just fine, Molten Freddy ''can't''.]]
38* ''A New World: Story of a lost Shinobi'': A picture of Naruto. Taken while Naruto was looking for Mystogan, by a guy on the train. Inadvertently starts the RunningGag of people saying Naruto is a Fairy Tail mage with him denying it. We find this out when a Rune Knight shows Naruto the picture in ''Sorcerer Weekly'' where it calls him "Fairy Tail's Orange Rocket".
39* In ''Fanfic/TheStoryToEndAllStories'', [[spoiler:when taking stock of their assets, Katniss Everdeen mentions her bow and arrows and Inigo Montoya mentions his sword, both of which come in handy later]].
40* ''Fanfic/WhereTheSunlightEnds'': The [[spoiler:arc reactor]] that Otto takes back to the Raimiverse in ''No Way Home'' comes back into play as a [[AppliedPhlebotinum potential energy source]] for his and Peter Two's portal.
41* In chapter 2 of ''Fanfic/WonderfulMazinja'', Taylor briefly mentions that she invented a gadget called "Wonder-Mop". Eleven chapters later, [[spoiler:her friend Emma smashes a tank using the Wonder-Mop]].
42* ''Fanfic/YouGotHaruhiRolled'' manages to turn ''the announcement of a new fanfic'' into one. In Chapter 56, Haruhi complains to the writer, superstarultra, about a fic he wrote in which she and all her friends are in FatCamp. Then Chapter 81 rolls around, where the version of Haruhi from that fic appears through a dimensional portal and devours an animate cheesecake that was wreaking havoc.
43* In chapter 20 of ''Fanfic/BoldoresAndBoomsticks'', when Lt. Surge brings Ruby and Weiss into the lounge of his gym to discuss strategy for dealing with the Grimm threatening Vermilion City, it is noted that there's a display case containing, among other things, three thunderstones. Later, Weiss uses one of the thunderstones to unleash a lightning strike powerful enough to destroy the construction equipment that the Geist leading the Grimm had possessed.
44
45[[AC:''TabletopGame/SeventhSea'']]
46* ''[[http://www.fanfiction.net/s/5139522/1/Homecoming Homecoming]]'': When her father Owen expresses his uneasiness about his daughter Colleen coming with the family [[spoiler:to parley with one of the Sidhe]], she just pats her guns, insisting on helping her grandmother Moira hunt down her (Moira's) hated brother. Later on, [[spoiler:Colleen willingly shoots her father in cold blood with those same guns when she comes upon Owen trying to help his not-so-sinister-after-all uncle escape]].
47
48[[AC:''WesternAnimation/{{Amphibia}}'']]
49* ''Fanfic/AMothToAFlame'':
50** In Chapter 2, during her and Grime's brief takeover of Newtopia, Sasha is noted to have bonded with Joe Sparrow, having learned how to tame him from Marcy on the way from Wartwood. This comes in handy in Chapter 7, when [[spoiler: it's Sasha who flies Joe to save Sprig after Marcy throws him out of the flying castle.]]
51** Another case that spans those same chapters — in Chapter 2, Sasha has several of her toad soldiers bring her all of Marcy's notes on the Calamity Box so that she can learn how to use it, which comes in handy in Chapter 7 when she's the one who opens a portal to Earth for Anne and the Plantars.
52** Chapter 13 has Sasha note the hairpin that Marcy once gifted her, which is the one thing related to her that Sasha hasn't gotten rid of. At the climax of the chapter, she [[spoiler:has Ivy use it as a projectile to set off some boomshrooms in order to enable the captured Resistance fighters to escape]].
53* ''Fanfic/YoureAboutSevenYearsTooEarly'': In chapter 8, Maddie enchants one of Sprig's slingshots to make it so it'll never miss. [[spoiler:Later in chapter 17, the slingshot plays a key role in the defeat of the Core, as Marcy uses it to knock an {{EMP}} out of Andark's pocket and into her hands, which she uses to destroy all technology in the Newtopia Castle.]]
54
55[[AC:''Literature/{{Animorphs}}'']]
56* ''Fanfic/{{Eleutherophobia}}'': Early on in ''[The Thing from Another World'', Tom notes that humans can get severe heavy metal poisoning from the atmosphere-vacuum coating used on spaceships. At the end, Alloran reveals that they can use it to cure Marco of TheVirus — they need to scratch his arm with a piece of vacuum coating, wait until it kills the pathogen, and then he can morph to heal the injury.
57
58[[AC:''Franchise/{{Arrowverse}}'']]
59* In ''Fanfic/TheHurricane'', after Laurel and Shado join the League of Assassins, Laurel realises that the invisible ink they use for writing messages is the same style of ink used in Robert Queen's notebook, which confirms a connection between the League and the List even if they can't find any evidence that ''Robert'' was connected to the League himself.
60
61[[AC:''Manga/{{Bleach}}'']]
62* In ''[[https://www.fanfiction.net/s/12913821/20/Game-and-Bleach Game and Bleach]]'', every time Ichigo defeats a boss, he gets a greater soul item which is seemingly worthless. Once Ichigo's transformed into a Hollow, consuming said souls boosts him from a pathetic level one to a more respectable (but still fairly weak) level twenty-seven [[note]]For reference, Ichigo had reached level 100 as a human while Yoruichi was level ''300'' and the weakest of Ichigo's classmates were at least level 3[[/note]].
63* ''Fanfic/{{Sight}}'':
64** While recovering in Fourth Divison after uncovering Aizen's coup, Ichigo hears the first echoes of his Inner Hollow in his soul. Zangetsu tells him this:
65-->If you know yourself, if you accept yourself, then there is nothing to fear.
66** Ichigo remembers this when his Hollow attempts to take over and chooses not to fight his inner Hollow as fighting against himself isn't accepting anything.

76
77[[AC:''Franchise/{{Danganronpa}}'']]
78* ''Fanfic/KazuichiStrangelove'': Kazuichi, going through a GroundhogDayLoop, spends time in the Funhouse with Fuyuhiko, learning more about the Yakuza heir's past with Peko and [[InterruptedSuicide stopping him from killing himself to free the others from the Funhouse]]. Fuyuhiko teaches Kazuichi a gesture called "The Russian Doll", which can be used to receive the aid of the Kuzuryuu Clan.

90** When the three pets first enter the title venue in "The Supermarket," they see grocery clerks preparing stacked displays of bananas, tomatoes, eclairs, and pies. The story ends with the three pets [[FruitCart caked in squashed examples of the same foods after Bolt's ill-fated rush to the store exit while pushing a shopping cart]].
91** Early on in "The Spaceship," Rhino is seen blowing into a dog whistle, which makes Bolt's ears hurt. When aliens beam the hamster aboard their FlyingSaucer later in the story with intent to kidnap him, Rhino convinces them to release him after repeatedly blowing on the same whistle. Given that the aliens very much resemble [[IntelligentGerbil bipedal canines]], they have the same pained reaction Bolt did and agree to the rodent's release once they find what they think is a substitute uber-intelligent being.

100* ''Fanfic/AlternateTailSeries'':
101** Part of the reward for the Galuna Island job were tablets that contained a type of holy letter magic. [[spoiler:Levy then used this magic to beat Freed during the Battle of Fairy Tail]].
102** Gajeel defeats Laxus by [[spoiler:striking him with Iron God Sword, forcing Laxus to transform into lightning and be disapparated into the Tower of Heaven]]. This proved vital, as Brain was able to bring back Laxus [[spoiler:by gathering the crystal remains of the Tower and collect Laxus's energy to bring him back together]].
103** Like in the anime, Erigor made a return during the Oracion Seis arc. However, not only does his coat get taken by Laxus, but his scythe is taken so it can be fed to Gajeel.

126[[AC:''Literature/HarryPotter'']]
127* ''Fanfic/HowFriendshipAccidentallySavedMagicalBritain'': When Tom moves in with Frances Cooper, a former cop, he gains an interest in handling and firing muggle firearms and spends his summers practicing his marksmanship at the local firing range, even getting a full gun license and his very own shotgun. Wizards are always caught off-guard when faced with muggle weaponry, after all, especially firearms, and bullets can be enchanted with runes to pierce common shield charms easily. Hence why Tom is able to simply blow [[spoiler:his alter-ego]]'s brains out in the story's climax.
128
129[[AC:''Webcomic/HetaliaAxisPowers'']]
130* ''Fanfic/{{Outcast}}''::
131** When Sweden/Berwald and Finland/Tino officially "adopt" Flower-Egg as their dog, Tino takes a little charm he's been using as a zipper-pull ornament and puts it on her collar in place of an ID tag. He mentions that the charm was a gift from his grandmother, but [[spoiler:after hitting his head and [[ForgottenFirstMeeting reliving his first meeting with Berwald]], he remembers that the ornament is actually a shell concealing the crystal star he took from Astrid's tomb -- Torvald's crystal star]].
132** On their first night as roommates (a flashback in Chapter 3), Denmark shows Tino the [[AxesAtSchool heirloom family battleaxe he brought to school]], reassuring Tino that he couldn't use it even if he wanted to as it's been securely bolted to the wall. [[spoiler:The same axe he used to nearly kill Berwald when he was thirteen.]] It crops up again:
133*** What does Denmark use to attack [[spoiler: Berwald]] in Chapter 5? The same battleaxe. [[spoiler:In his rage he rips the restraining bolts right out of the wall.]] Russia uses his enhanced strength to absolutely mangle the axe when the Student Council intervenes in the incident, but Denmark is allowed to keep the pieces as a reminder of his misdeeds.
134*** In Chapter 17, [[spoiler:when Torvald/the Spirit of Ancient Scandinavia is about to destroy the Foundation Stone (good!) and kill Tino (very bad!) with a single hammer blow, Denmark saves the day by smashing the stone with the twisted remnants of his axe.]]

137* ''Fanfic/AsylumOfDoom'': Patricia, one of the other patients in the [[BedlamHouse Burke Lunatic Asylum]], at one point attempts to maim Gaz with a shiv she made out of a sharpened plastic utensil. Gaz later steals this shiv and [[spoiler:tries to use it on Dr. Burke, which makes him resort to lobotomizing her — and this apparently "kills" her and returns her to her own time.]]
138* ''Fanfic/BecomingATrueInvader'':
139** The "resources" that the Resisty gather for [[BigBad the Employer]] on Earth. These later turn out to be [[spoiler: moose that he's augmenting into SuperSoldiers]].

141** Dib's utter lack of an ability to aim while shooting a blaster is ultimately what saves the day, as [[spoiler:he misses when shooting at the [[BigBad Minimoose]]-[[GrandTheftMe possessed]] Zim and hitting Kor instead, splattering her [[BizarreAlienBiology paralytic blood]] over Zim's body. This causes Minimoose to freeze up and give Zim the opportunity to [[FightingFromTheInside retake control]]]].
142** The [[BagOfHolding Dimension Box]] that [[MadScientist Crax]] gifts to Zim. [[spoiler:Minimoose steals it after losing control of Zim's body and uses its arsenal as leverage to buy himself time to escape through an interdimensional portal. However, the portal and the box react negatively to each other, creating a black hole that sucks in Minimoose, getting rid of him for good.]]
143* Midway through ''[[https://archiveofourown.org/works/52852729/chapters/133686367 Gaz and the Exchange Student from Hell]]'', Gaz is seen looking through a book called "Curses for Dummies". At the story's climax, [[spoiler: she uses a spell from it to [[GlamourFailure expose Circe for the demonic Cuckoo that she really is]], ruining her plan to force Gaz out of her family and replace her.]]
144* ''Fanfic/InvaderZimABadThingNeverEnds'': The Ceramic Clown Puppy.

148*** In Episode 8, Norlock gives Gaz [[MyCard his card]] in case she ever wants future advice or mentoring. In Episode 19, she finally uses it to call him [[spoiler: in order to betray Dib by giving Zim the location of [[LostSuperweapon Project Domination]]]].

153* ''Fanfic/RubyPair'':
154** Early in "Gaols & Ghouls", Zim reveals that his latest plan involves spreading around mind controlling fungal spores.

155** In "Frosting the 13th", while packing for the mission to Vort, Gaz attacks Zim with a brain-eating squid for annoying her. At the chapter's climax, Zim uses that squid to attack Larb as a distraction so that his team can get to his snack stockpile.

167[[AC:''Franchise/TheLegendOfZelda'']]
168* ''Fanfic/ZeldasHonor'': There are dozens of hints, foreshadowing and plot devices introduced in the first and second Acts that don't come into play until much later in the story during Act 3. Most of the list is located at the tropes page but a notable one is Link's mentioning of the need for balance between Power, Wisdom and Courage during Act 1 which prompts [[spoiler:Ganondorf]] to rethink his motives which leads into an almost near win for him in Act 3.

173** Also, Vesta's possession by a Jewel Seed [[spoiler:turns out to be crucial to Precia's plan to revive Alicia.]]
174** The [[NightOfTheLivingMooks zombie animating]] Jewel Seed is what inspired Precia to create her temporary life-support system for Alicia to use when they travel to Alhazred. [[spoiler:And then it turns out that Precia actually used that very Jewel Seed to revive Alicia fully.]]

177* ''Fanfic/SixesAndSevens'': The photonic amplifier, which appeared as plans in ''Series/AgentCarter'' and a prototype in a preceding chapter, is used by Sue Storm in conjunction with the Gamma Cannon to make a light-based weapon that Arclight's powers can't deflect.
178
179[[AC:''Franchise/TheMatrix'']]
180* In ''The Return of Fanfic/WhatIf'', the fic opens with a group of enhanced agents trying to find something in the real world to help them deal with Neo, who currently exists as a 'glitch' in the Matrix ever since he downloaded his consciousness fully into the Matrix when Cypher pulled his plug. It is eventually revealed that [[spoiler:the programs were seeking Neo's body, which was kept on a form of life support after the Machines realised he was still 'alive' in the Matrix, Neo and Trinity tricking the Machines into giving them access to a link-up that allows Neo to download himself back into his body before the destruction of the Matrix]].
181
182[[AC:''Franchise/MegaMan'']]
183* ''Fanfic/MegaManDefenderOfTheHumanRace'' has many examples, but a specific kind of head pain is a recurring one, happening to [=ProtoMan=] upon activation, Mega Man due to the scrambler chip, and Nomad upon activation.
184** Chapter 1 states that robots can't self terminate at the behest of humans. This saves Drill Man in episode 8.
185** In episode 12, [[spoiler:[=ProtoMan=] stealing Roll's [=SkyCycle=] led to it running out of fuel at a crucial time]].
186* ''Fanfic/MegaManRecut'':
187** The password Proto Man gives Mega Man in "Future Shock".
188** Dr. Light's journal is taken by Mega Man in "The Mega Man In The Moon" but doesn't come up again until the next episode.
189
190[[AC:''WesternAnimation/MiraculousLadybug'']]
191* ''Fanfic/OhYouDontHaveToDoThatCommunication'': Nino and Kim casually mention in a private chat between them and Marinette that Marinette has a "sour habit" that happens when something serious happens, base on an event in second grade. [[spoiler:Near the climax, the "habit" is revealed to be a reference to Marinette using a batch of sourdough she failed to recognize since she can’t taste anything sour. This gets used to [[ImpostorExposingTest expose Lila as an imposter]] when she uses an akuma to disguise herself as Marinette]].
192
193[[AC:''Manga/MyHeroAcademia'']]
194* ''Fanfic/EnneaSeries'':
195** Katniss notes that Hawks is fairly androgynous as a teenager, and it never fully goes away. This comes in handy for when the Eight use his body as the vigilante persona Ennea, as observers cannot tell whether Ennea is male or female.
196** The phrase "remedial courses" is used as DoubleSpeak for when a Commission agent is going to be sent to reconditioning. [[spoiler:Tokoyami tells Hawks he fears he will be sent to remedial courses, making Hawks think Tokoyami is being targeted. Before he realizes Tokoyami meant the phrase in the literal school-type sense, Hawks lets slip what it means to agents and that the Commission brainwashes Heroes. This exposes Tokoyami to the darker side of the Hero Commission and Hero Society.]]
197* In ''Fanfic/{{Switchblade}}'', Kesagiri Man teaches Izuku during his internship about Stasis Tranquilizers, special drugs that makes it look like someone is dead without actually killing them.

201* ''Fanfic/{{Anthropology}}'': [[spoiler:Before being sent back to the human world]], Lyra is given a necklace in the shape of her cutie mark by Princess Celestia. [[spoiler:After Discord turns Lyra back into a pony, her magic activates an enchantment on the necklace that returns Lyra to Equestria, to she can bring the Elements of Harmony to Earth and stop Discord's reign of destruction.]]
202* ''Fanfic/{{Contraptionology}}'':
203** Applejack learns two phrases in honeybee dance. Later she has to talk to a honeybee hybrid using one of the phrases.
204** [[spoiler:"BRAINHUG!"]] Early in, Twilight uses a JourneyToTheCenterOfTheMind spell to talk with Applejack in private. In the climax, [[spoiler:Nightmare Delicious/Applejack uses the same spell to talk to Twilight after the latter has become a helpless BrainInAJar]].
205** [[spoiler:Discord]], using Stranger von Danger as proxy, makes a Pinkie Promise at the Tesseract Party, despite not having any intention of keeping it.
206** Rainbow Dash forgetting what her actual element is [[spoiler:is the real reason she was immune to the mad science]].
207** Iggy the Salamander, and his ability to [[spoiler:burn even unburnable things if fed distilled essence of pepper]], becomes key to solving the conflict in the climax. For that matter, [[spoiler:Applejack]]'s invention is integral to their final plan despite it having nothing to do with its intended purpose.
208** Derpy still holding on to one mostly-spent thundercloud ends up becoming a necessary part of the heroes' plan towards the ending.
209* ''Fanfic/TheFlashSentryChronicles'':
210** When Discord lists several random facts about Flash during their fight he offhandedly mentions Flash has the rare triple Z blood type. Flash later remembers this when he learns that Scootaloo has the same blood type, meaning he can donate some of his blood for her in a blood transfusion.
211** Soarin demonstrates a technique he learned during his race with Rainbow called the Theta State. Flash is shown training to try to achieve this state during numerous chapters in Season 2 afterwards and [[spoiler:later achieves it during the Changeling Invasion in "A Canterlot Wedding"]].
212* ''Fanfic/AFutureOfFriendshipAHistoryOfHate'':
213** During their first fight in Episode 3, [[ArchEnemy Fury Cross]] manages to wound Rainbow Dash with a small slash on her side, which is referred to several times over the course of the chapter as having not healed. [[spoiler:During their rematch, it turns out to be a wrath wound, which has been feeding off of her anger and frustration at him and her friends in order to leech her strength. This allows him to nearly kill him before her friends show up to save her.]]
214** In Episode 4's [[TheTeaser teaser]], Rarity collects dew pearls for a dress she's making, as it later turns out, for [[spoiler: Fluttershy as a birthday present]], which she ends up forgetting about completely due to all the time she's spending with [[BitchInSheepsClothing Regal Rule]]. The realization of this when Sweetie Belle points it out is what triggers her MyGodWhatHaveIDone moment.
215** The hoof-made wing guards Scootaloo gives Rainbow Dash as a gift just before her flying lesson in Episode 5 are later used as proof by Dash that Scootaloo ''can'' do stuff right -- when everything else in that episode had convinced her she couldn't -- as part of a RousingSpeech that pulls her out of her DespairEventHorizon [[spoiler:and allows them to defeat the woebeghoul that was feeding on Scootaloo's despair]].
216* In ''Fanfic/TheImmortalGame'', it's repeatedly mentioned that the easiest way to defeat a [[MasterSwordsman bladecaster]] is to [[BreakThemByTalking break their faith]] in what they're fighting for, which makes them lose control of their blade. We see an example of this about two-thirds of the way through the story, when Sir Unimpressive defeats [[MookLieutenant the Cadet]], but in truth, this was setting up for how [[spoiler: Twilight defeats [[BigBad Titan]] during the FinalBattle]].
217* ''Fanfic/LovedAndLost'':
218** In the second chapter, Prince Jewelius shows Twilight Sparkle from a spell book a power-draining spell that can be used to shrink multiple beings at once. During the Changeling invasion, he reminds her of the spell and reveals a glass jar, prompting her to use the spell, turning all the Changelings tiny enough to trap them inside the jar. She [[PowerStrainBlackout becomes very tired and falls unconscious]] as [[ManipulativeBastard Jewelius]] usurps the throne by turning everypony against all the other heroes.
219** When Spike is exiled from Equestria, Jewelius gives him the wedding cake toppers the baby dragon played with [[KickTheDog as a taunt]]. During the final battle, Spike [[spoiler:wedges them into one of the wheels of Jewelius' chariot, [[HoistByHisOwnPetard preventing him from escaping]] as things go south for him]].
220* In ''Fanfic/ManehattansLoneGuardian'', Leviathan initially views a letter given to her by a little colt and his mother encouraging her to return home as unimportant, though Drama tells her to hang onto it. Much later, when dealing with a negative situation, re-reading the letter helps spark a series of reminders that tell her that her goal of going home isn't yet out of reach.
221* ''Fanfic/NaturalHistories'': The salamander egg in "The Fountain", laid at the start of the chapter and not mentioned again until [[spoiler:it hatches at the end, incinerating all the other creatures in the clearing]].
222* ''[[http://www.fanfiction.net/s/7721358/1/A-New-Hero A New Hero]]'': Over the course of the first season, main character Alex gets gifts from each of the Mane Six. After Discord {{Mind Rape}}s him into such a bitter, insular person that not even Twilight's memory spell can snap him out of it, he sees those gifts, which remind him of his friendship with the others, restoring him to normal.
223* ''Fanfic/ThePowersOfHarmony'':
224** More like Chekhov's Location, but Dragon Turtle Lake — which Fluttershy and her Guards visit fairly early in the story — ends up being chosen as a meeting place by Luna after [[spoiler:the group is scattered]].
225** Twilight's thesis spell turns out to be [[spoiler:the only thing strong enough to permanently destroy [[BigBad Cetus]]. [[SealedGoodInACan Harmony]] [[LongGame naturally influenced this]]]].
226* ''Fanfic/PrincipalCelestiaHuntsTheUndead'':
227** [[spoiler:Shortly after moving into Celestia and Luna's home, Sunset unwittingly discovers that Principal Celestia's bare legs somehow amplify light. She later uses this ability as an ImprovisedWeapon against a pack of ghasts.]]
228** [[spoiler:Earth's Zecora and a non-Equestrian unicorn]] are introduced in chapter 8, helping Celestia and her group. They return in chapter 31 to [[spoiler:save Luna and help in the battle for CHS]].
229* ''Fanfic/TriptychContinuum'': ''Triptych'' opens with Discord granting Fluttershy the ability to permanently remove one thing. She hasn't used the ability yet, [[spoiler:but it's been implied she's considered using it on the mysterious pony that painfully transitions between the three tribes..]].
230* ''Fanfic/UnderTheNorthernLights'': Before Twilight leaves Equestria, Pinkie gives her a party grenade that can instantly deploy a party's worth of decorations anywhere, in case she needs to throw a party on short notice. Much later, [[spoiler:this proves invaluable when Spike uses it to bluff a group of reindeer pirates into thinking that the mad RealityWarper Discord has come back]].
231%%* ''Fanfic/TheWritingOnTheWall'' has both the eponymous writing and the sick workers.
232
233[[AC:''Manga/{{Naruto}}'']]
234* ''Fanfic/{{Blind}}'': The Kyuubi negotiates a deal with Naruto about what he can and can't do when Naruto allows him take over of his body during the month long wait for the 3rd part of the exam before they discuss Naruto's training. This later comes in handy during the fight with Gaara and various other points in the story.
235* ''Fanfic/{{Chiaroscuro}}'': The identification wristbands given to the competitors during the Chunin Exams are explained in some detail during the narration. Shikamaru manages to hack the seals and uses them to incapacitate Orochimaru.
236* ''Fanfic/{{Space to Breathe|Naruto}}'': When Sakura decides to sign a summoning contract, she finds herself torn between two possibilities: the owls and the scorpions. Ultimately, she settles upon [[spoiler:the latter]]. The other contract comes back into play when it's eventually revealed that [[spoiler:Hinata]] has chosen to sign it instead.

239* ''Fanfic/AdviceAndTrust'': When Asuka [[spoiler:fights the Thirteenth Angel]] she sees [[spoiler:Bardiel has grown an S2 Organ in the Unit 03's body when it infected the HumongousMecha]].

Later they have to [[spoiler:help Rei to fight Zeruel]] but they can not use their own giant robots, so that they [[spoiler:hijack the intact Unit 03]]. During the battle it runs out of power... but [[spoiler:since it has a S2 Organ, it can keep moving]].
240* ''Fanfic/TheChildOfLove'': One chapter has Ritsuko tell Misato "Trust me". In the final chapter, [[spoiler:Misato realizes that "Trust me" is the password to access Ritsuko’s personal logs]].
241* ''Fanfic/ACrownOfStars'': In one of the first chapters Shinji and Rayana retrieved Yui's soul from Unit 01 and they left the giant robot parked in a specific spot until they figured out what doing with it. At the same time Asuka got a new shiny mecha capable to interplanetary travel. In chapter 48 [[spoiler:Shinji and Asuka's army needed a power supply and Shinji thought of Unit 01's S2 core… that they could retrieve using Asuka's [[AMechByAnyOtherName Red Whirlwind]].]]
242* ''Manga/Evangelion303'':
243** In chapter 3, [[http://eva303.smackjeeves.com/comics/918667/044/ Shinji mentions to Asuka where he keeps his gun]]. She later [[spoiler:uses it during her attempted suicide]] in chapter 12.
244** [[http://eva303.smackjeeves.com/comics/1743748/035/ In the page 35 of chapter 11]], Shinji mentions to Asuka that they had not celebrated her birthday yet and he would like to throw her a party. Then they fight and the birthday issue becomes forgotten... [[http://eva303.smackjeeves.com/comics/1795210/046/ until the page 46 of chapter 12]] -- almost two-hundred pages later and published three months later -- when Shinji reveals that he had actually bought her a birthday gift -- [[spoiler:an engagement ring]] -- (and suddenly you realize that he was thinking about moving towards the future right before bringing the birthday matter up).
245* ''Fanfic/GhostsOfEvangelion'': In 2019 Asuka finds several documents proving that Yui was already planning everything during her college years. Many years -and chapters- later, she handed over them to Shinji.
246* ''Fanfic/{{HERZ}}'': In chapter 5 it is mentioned briefly that Shinji can not hold his liquor. Several chapters later [[spoiler:it is revealed that Kurumi used his lack of endurance to take advantage of him in the past]].
247* ''Fanfic/HigherLearning'': Asuka and Shinji play ''[[Music/PachelbelsCanon Kanon D-Dur Quartet]]'' while practicing for a school concert in episode twenty. Thirty chapters later Shinji has unsuccessfully been trying to find Asuka [[spoiler:in the Instrumentality]] for a long time. Then he plays Kanon D-Dur Quartet... and she finds him at last.
248* ''Fanfic/OnceMoreWithFeelingCrazy88'': Shinji returns to the past carrying Misato's cross pendant with him. He briefly considers throwing it away to avoid awkward questions, but he decides to hide it in a safe place. Many chapters later [[spoiler:he reveals Kaji where he hid Misato's pendant. Kaji gets the trinket analyzed and it proves conclusively that Shinji is indeed a time-traveller]].
249* ''Fanfic/TheSecondTry'': Several instances:
250** In chapter 2, Shinji and Asuka checked the Tokyo-3 hospital, and found that it seemed to be in perfect shape and the emergency power-generator was still working. Asuka stated that it could be useful in the future. In chapter 6, [[spoiler:Asuka gave birth Aki in that hospital]].
251** In chapter 3, Shinji slips an "Anonymous" letter into Misato's jacket. Several chapters later, [[spoiler:Misato finds it during the aftermath of the battle with the 14th angel, and leads to her learning of Shinji and Asuka's secret.]]

262** Akira gets two Jack Frost plushies for the twins. [[spoiler: Lavenza later comes up with the idea to use them to pass notes between him and Akechi.]]
263* ''Fanfic/ThrowAwayYourMask'':
264** The healing items Akechi gives Shinjiro for his birthday later [[spoiler: save him from succumbing to his wounds on October 4th.]]
265** A literal example in Akechi stealing Takaya's revolver. It's fired [[spoiler: during Chidori and Akechi's scuffle the night after she learns he has it, non-lethally injuring her shoulder]], and again later [[spoiler: by Akihiko, accidentally killing Chidori while trying to shoot Takaya.]]
266
267[[AC:''Franchise/{{Pokemon}}'']]
268* ''Fanfic/DenounceTheEvils'': Jessie receives a Fire Stone in chapter four. Twelve chapters later, it's used in the climax of the chapter [[spoiler:for James to evolve his Growlithe]].

273
274[[AC:''Anime/PrincessTutu'']]
275* ''Fanfic/AnUncommonWitness'': The MafiaPrincess Rue Corvo takes a liking to NaiveEverygirl Duck Stannus and gives her a napkin with the phone numbers of her house, her father's house and her agent. [[spoiler:Turns out that those numbers help Duck to contact Rue in order to beg her for Fakir's location after some of Domenico's men abducted him and Autor.]]
276
277[[AC:''VideoGame/ProjectArrhythmia'']]
278* ''VideoGame/TheAramaArchives'': Midway through ''Ad-[=OwO=]-ble'', [[spoiler:the player passes by a shelf full of "space milk" while on the way to destroy the [=OwO=] Spray in the Space Mart. Near the end of the collection, in the level Meowter Space, Kitcat pulls out some space milk and drinks it to power up - revealing that the spray was a distraction from its real superweapon.]]
279
280[[AC:''VideoGame/{{Psychonauts}}'']]
281* ''Fanfic/LaterTraitor'': Early on in the story, Ford bribes Frazie with a Dream Fluff to get her to stop prodding him about wanting bacon. In Chapter 11, the Dream Fluff gives Frazie a HeroicSecondWind against an overwhelming onslaught of Intrusive Thoughts.

285
286[[AC:''Literature/ASongOfIceAndFire'']]
287* ''Fanfic/RobbReturns'':
288** In chapter 63, Jon Arryn manages to [[spoiler:make a deep cut into Lysa's arm as she attacks him.]] Eleven chapters later, [[spoiler:the cut has festered and corrupted, forcing Lysa's men to pull into the closest keep - which turns out to be Bronn's]].
289** Before Littlefinger gets arrested in chapter 35, he thinks of a letter he managed to send just in time for this case. [[spoiler:Chapter 77 shows that the letter was sent to Lysa Arryn, telling her about Cersei and Jaime's incest and their children, and also that Lord Arryn was lying about his crimes and plotting to kill him, which led to Lysa's attack against Jon.]]
290** [[spoiler:When he jumped to his death]] in chapter 72, Patchface claimed it was "A life for a life". Chapter 77 reveals [[spoiler:his death paid off for Shireen being healed of greyscale, burning off the scars left behind]].
291** While they prepare Winterfell for the future arrival of the Royal Court and the war with the Others, Ned makes a mention in chapter 62 about having the Broken Tower repaired in a special way. [[spoiler: In chapter 116, the nature of these repairs is revealed, allowing Ned and several others to catch Jaime and Cersei Lannister mid-coitus.]]
292** In chapter 56, when Robert brings Stormbreaker to Tobho Mott's shop to find out what makes it so special, the blacksmith sounds it, and while he and Ser Barristan hear a clank, Robert and Gendry hear a chime. [[spoiler:In chapter 117, Robert uses this to make sure whether Joffrey, Myrcella and Tommen are his children, as only someone of Durrandon blood can hear the chime. None of them do.]]
293** In chapter 58, Jaime's sword somehow rusted from the inside really fast as he fought against Robert, who was wielding Stormbreaker. [[spoiler:In chapter 120, during Jaime's TrialByCombat, Robert wrecks every weapon and protection Jaime carries because they rust really fast.]]

295[[AC:''Franchise/StarTrek'']]

297* The author of ''Fanfic/NotQuiteSHODAN'' likes these quite a bit. A short and soon-forgotten-about incident in the second book is the first piece of foreshadowing for the entire plot of the sixth book, a year later.
298* ''Fanfic/RedFireRedPlanet'' has a mention in chapter one that the Bird-of-Prey ''[=Hegh'QeDp=]'' is having engine trouble and had to fall out of the formation. [[InsaneAdmiral General K'Bor]] complains about their cowardice, but Brokosh points out that it's hardly cowardly to shut down your reactor when when you've got a microfracture in your fusion bottle. [[spoiler:The cloaked Bird-of-Prey is later detected by the crew of a Starfleet listening post, and after it blows up a shuttle containing two of the crew members the station raises the alarm.]]
299* ''Fanfic/ShakedownShenanigans'': Eleya's customs declaration when she arrives at Vulcan includes three cases of springwine. One bottle is used in the launch ceremony, [[spoiler:and one case was used to bribe the shipyard fueling manager into giving the USS ''Bajor'' a full tank before launch]].
300* ''Fanfic/StrangeTimesAreUponUs'': Ba'wov notices a pair of heavily armed men with a dog in a tavern in Williamsport, and shortly after she interacts with a black man named Benjamin Smith who's part of the Underground Railroad. [[spoiler:Meromi later encounters the men and dog as slave hunters pursuing several escaped slaves led by Smith.]]
301* A minor case in ''Fanfic/TheWrongReflection''. Master Chief Operations Specialist Peter Wiggin, the MauveShirt manning the sensor station on the USS ''Bajor'', comments late in chapter three that it feels spooky that Terran Empire warp drives look exactly the same as Federation drives. [[spoiler:It turns out in the next chapter that the Klingon-Cardassian Alliance and the Terran Empire can't tell the difference either, allowing the ''Bajor'' to [[BigDamnHeroes pull a surprise attack and rescue an Alliance patrol from Terran reinforcements]].]]
302
303[[AC:''Franchise/StarWars'']]
304* Fanfic/ASwordToPass
305** Earlier in the story it is stated that Alrich has his own armor but doesn’t often wear it. Come chapter 38, while he and Tristan are investigating sabotage, they come under attack form the perpetrator and they take a swing with a knife at Alrich which he uses his arm to protect himself and reveals that he is wearing his armor under his clothes.
306** Within the same fight the hidden blade that Ursa gave Tristan comes in handy when he stabs the saboteur in the throat several times.
307
308[[AC:''Series/{{Supernatural}}'']]
309* ''Fanfic/MaybeSproutWings'': The fact that Castiel doesn't destroy Dean's collar and instead puts it in his safe comes up later when [[spoiler:Alastair tracks Dean down using the collar. There are also two other plot points that fans of the story speculate will factor in the climax. The fact that the date on Dean's paperwork is a month off indicates he might have signed himself over illegally. Also, in this universe, there is a true mate clause that allows mated people to be freed if they are bonded to another person. Castiel has rejected this as old fashioned and not how he wants to free Dean, but it will likely come up again]].
310
311[[AC:''ComicBook/TeenTitans'']]
312* ''Fanfic/NewTamaran'': The morning after Robin proposes, Starfire accidentally reveals she's been given a Violet Lantern ring, but hasn't put it on due to fears that being a Lantern will take her away from her friends. [[spoiler:Guess what she uses to defeat her Red Lantern sister.]]
313
314[[AC:''Franchise/TolkiensLegendarium'']]
315* Invoked in Limyaael's ''Fanfic/TheGameOfTheGods'', chapter 30, "Rapture's Redemption". Manwë's approach is to reconstruct the titular Sue in a way such that she actually fits into the setting (rather than using deconstruction to unmake her with logic). Among other things, when the story mentions Rapture having a magical amulet, he immediately points out that such a thing is completely superfluous and doesn't need to be mentioned unless it's a defining trait or relevant to the plot. It's immediately excised from the story, along with plenty of other unnecessary baggage.
316
317[[AC:''WesternAnimation/TotalDrama'']]
318* In ''Fanfic/{{Legacy|TotalDrama}}'', Heather's pregnancy is mentioned [[RuleOfThree thrice]] in the first chapter but doesn't become important until near the end.
319* Lindsay's bandana in ''Fanfic/TheLegendOfTotalDramaIsland''. When Lindsay arrives on the island, {{the Storyteller}} notes that her bandana would serve her well, but leaves the details as "[[CatchPhrase another story for another time]]". Sure enough, several chapters later, the presence of that bandana mitigates the damage when [[spoiler:Lindsay's hair is burned]].
320
321[[AC: ''WesternAnimation/TurningRed'']]
322* In ''Fanfic/TurningRedThePandaConspiracy'', both the panda in the glass tank, as well as the security cameras dotted around Xia's house both come in handy for defeating Harvey.
323
324[[AC:''WesternAnimation/YoungJustice'']]
325* ''Fanfic/WithThisRing'':
326** Scott was to recharge his ring despite the ban from the Guardians to help the Green Lanterns deal with [[spoiler:Paulphidian]]. He and the Lanterns get curb-stomped before they could stop them. [[spoiler:Since Alan's ring still has most of its charge, he decides to help Paul and the Team fight the Light and free the Justice League.]]
327** Paul jokes that he's not going anywhere the Greek Pantheon after Father Mattias makes a crack about their unreliability compared to Yahweh. He not only picks Eris, the Greek Goddess of Chaos as a his patron god during his visit to Thymyscira but meets Eris and Hera in person. [[spoiler:And successfully convinces Hera to divorce Zeus.]]
328
329[[AC:''Anime/YuGiOh'']]
330* ''Fanfic/ArcVedProtagonists'' gives us both a subversion and a straight example at the same time in "Dark Fusion". At one point, Jaden has to discard his entire hand and we see all the cards discarded. Among the cards is Necro Gardna, a card that has an effect allowing it to negate an attack when it hits the graveyard. You can be forgiven for thinking Necro Gardna was going to be used latter on, but that winds up being a RedHerring. Also among those cards is Elemental HERO Burstinatrix, a level 3 normal monster that is also used as fusion material from the graveyard by the effect of a card Jaden latter plays.
331* In ''Fanfic/LoadedBones'', St. John's wart turns out to be a ward against evil spirits, and Ryou running out is the cue for Yami Bakura to take over again.
332
333[[AC:Unsorted]]
334* Literally in ''[[http://www.fanfiction.net/s/8769956/8/Sin-City-Kids Sin City Kids]]''. Vincenzo Salvatore passes on the family revolver to Vinnie, at his 30th birthday party. Several chapers later,[[spoiler:Billy the Kid maims Tony with the gun to avenge Vinnie]].
335%%* ''Roleplay/TheTravelsverse'' is basically one big armoury, with Instrutilus constantly placing guns in advance and using them stories later.
