- There's an interesting anecdote about John Dies at the End regarding Camel Holocaust, the "song" that John wrote for his band early in the book. In the original webnovel, the protagonists have to stall a group of monsters at a later date by playing Sweet Child O' Mine on a set of guitars they stole from Elton John. When the book was to be put into print, however, the issue of copyright came up. The author stared dumbly into space, scratched his butt, and realized that he had left Chekhov's Gun sitting in his back pocket. Thus, the day was saved by
Fat Jackson's Flap WagonThree Arm Sally.
- Whateley Universe:
- The Whateley Weapons Fair at Whateley Academy. Phase is asked to try a forcefield disruptor by an inventor who has very little cred. It's just the thing Phase needs at the end of the Fair, when someone's weapon makes everything else go haywire. Then, much later, Phase uses another one of the forcefield disruptors in a fight, and it blows up on her.
- The Weapons Fair is turning into a Chekhov's Armoury. The attack devise in Knick-Knack's 'lava lamps'? Used to attack Phase in a much later novel. Phase's run-in with Kew and the Spy Kidz? Important in "Ayla and the Networks". There seems to be a lot of these.
- Face it, the Phase novels are nothing but Chekhov's Guns. Some of the background issues in Ayla 1 turned out to be key plot points in Ayla 6. Phase's concern with the New Olympians in Ayla 4 turns out to be critical in Ayla 7. Delta Spike's rambling in Ayla 7 about a course she took last year turns out to give Phase a crucial clue early in Ayla 8. And those are just some of the ones where the gun doesn't get fired in the novel where it's shown.
- This well-known succession game of Dwarf Fortress has an example — an early ruler builds a catapult in the souther parts of the outdoor plains to take out problem elephants, get rid of surplus stone and train siege operators. Due to a lack of manpower and constant attacks, it never sees use and isn't even mentioned again. When a later ruler allows magma flow from Project Fuck The World to reach the southern parts of the map, it sets the catapult on fire. The smoke clouds and spreading blaze from that one structure ultimately lead to the fortress's downfall.
- Then there's the later succession game Headshoots, and The Inexplicable Room and the path to it. Nobody remembered making either, no ruler could find how it connects to the rest of the fortress, and it could only be found via the 'find unit' function. Even a majority of the dwarves couldn't find their way in or out. The final turn, where the two unbelievably-strong soldiers Holistic Detective and Nemo2342 were skeletonized and sent against the entire fortress, the only surviving dwarf hid in the parth to The Inexplicable Room.
- A weird little news brief from The Onion.
- At the beginning of Just Another Fool, there's a random vignette about Logan's watch. Later, it becomes a major clue for a puzzle.
- In an early Fine Structure story, Seph thinks to herself that Mitch, who can phase through things, could kill someone instantly by materializing his hand inside their head, but she doesn't think he'd do that and doesn't mention it. Near the end of the series, he does just that.
- At the beginning of Eliezer Yudkowsky's article "The Simple Truth" the author uses an analogy to advise people not to abandon the concept of truth, using the example that even when gravity wasn't understood, people had the common sense not to walk off cliffs. By the end of the story, Markos Sophisticus Maximus denies the concept of truth, and walks off a cliff.
- At the start of Greek Ninja, Sasha mentions having odd dreams, which although it's implied there is some importance to them, they are otherwise dismissed, until it's revealed in the fourth chapter that they are actually memories from Sasha's previous life as Eli of Thrace.
- At one point in Worm, Doctor Mother mentions that one of Cauldron's capes can De-Power parahumans. It gets used on Taylor at the end of story.
- Sf Debris has one in his review of Puella Magi Madoka Magica the Movie: Rebellion where he begins the review with reading parts of the tale of the Soldier and Death in which a soldier manage to trick Death into a magic bag. He returns to it later when Homura forcibly split Madoka from Madokami.Chuck: (In the beginning of the review) Soon he laid there in his own sickbed, waiting for the arrival of the woman, who was the embodiment of Death, to come and take him away. And when he saw her there, near his head, coming to take away the soul of this old soldier, he asked her: Do you know what this is?. She looked and said: It's a sack. Well if it's a sack, he said Get into it! And immediately she was trapped within the sack of the soldier, who bound it tightly and felt quite, quite pleased with himself.Chuck: (Later) The moment has finally arrived. After all the endless fighting Madoka has come to claim this soul, and all this old soldier can say to her is: If it's a sack, Get into it!
- In the first chapter of The Tim Tebow CFL Chronicles, it's revealed the Canadians fundamentally don't understand the purpose of locks. Much later, the Toronto Argonauts (with guidance from their few American members) realize they can evade a massive Zerg Rush from the Atlantic Schooners by luring those opposing players into chambers on a (non-Canadian) aircraft carrier, and just locking them into the room.
