Sometimes the most interesting revelations aren't delivered with a dramatic speech, a round of shocked expressions and a title card reading "to be continued". Sometimes they're just handed out casually, tossed in the audience's face without fanfare or even a helpful sign saying "this is important". In many cases, it's not until Fridge Logic kicks in that the audience has a chance to react.
These are Info Drops, which are to Infodumps what a single stealth paratrooper is to a nuclear warhead.
While rarely relevant to the actual plot, an Info Drop usually fleshes out subtle details of the setting and/or characters, usually nagging questions that will continue to nag the less-attentive. For instance, say a character has Only One Name; there might be an Info Drop where he writes his full name on a check, or perhaps someone calls out his missing surname (or given name), and this is the one and only time it's either seen or referenced. Or perhaps it's never explicitly said when the story takes place, but there is a date that appears somewhere that can be cross-referenced with the events of the story.
- In Elfen Lied, we only learn about Lucy's real name when Kouta reads the letter she wrote as a child. It's Kaede.
- In the anime adaptation of Full Metal Panic!, Chidori mentions that she's an orphan when bitch-slapping a captured enemy. "Oh, you've got no parents? Well, same for me and Sargent Sagura over here." Up until that point, it's not explicitly stated that her parents are dead, and the statement goes a long way toward explaining her character (and current living conditions).
- Gundam 0080 and Gundam ZZ provide Info Drops for fans trying to figure out when exactly the Universal Century takes place. The former has a newspaper that reads "Monday, 14 January 0080", while the latter has Axis proclaim itself Neo Zeon on February 29th 0088, which means 0080 is a leap year in which January 14th falls on a Monday. The original series and Mobile Suit Zeta Gundam both suggested that the calendar changeover happened in 2000, but these pieces of information were quietly retconned out in the Compilation Movie versions.
- Negima! Magister Negi Magi has what appears to be a joke from one of the characters (later revealed as the arc's Big Bad) when she claims to be from Mars. Yeah, turns out that it wasn't a joke.
- One Piece thrives on this. Often tidbits mentioned in passing are revealed to have enormous significance. Eiichiro Oda's usual ploy is to have something relevant to the current arc, only to expand upon it at a later time. Continuity Porn contains one of the most major examples of this.
- Kalash93 loves this trope and uses it to great effect for world building and characterization. The second chapter of Racer And The Geek contains an inestimably important piece of information given just in a casual conversation. Likewise, a core point of plot development and foreshadowing vital to that story takes place in a conversation in Relax.
- After the four first return to the real C'hou in The Keys Stand Alone: The Soft World, Paul talks about things that happened to him underwater. It's only some time later that John realizes this means that Paul was underwater and didn't drown. (The four were very distracted when Paul first said it.) Paul confirms that he learned he didn't actually need to breathe a few days earlier, when he froze so thoroughly after going to high strength and nearly killing someone that he stopped breathing.
- The protagonist of Kill Bill is usually known only as the Bride, but there are hints and one specific scene that reveal her name to be Beatrix Kiddo.
- The protagonist of The Matrix is generally called either Neo or Mr. Anderson. His first name, Thomas, is mentioned only once, during his interrogation by Agent Smith near the beginning of the film.
- In the film of No Country for Old Men the date is only revealed from the fact that a 1958 coin "has traveled 22 years to get here".
- While the film version of Watchmen pretty much makes Ozymandias as Ambiguously Gay as possible, the real proof comes from a desktop icon labeled "Boys" on his computer.
- Pop Up Video: The premise is to provide a whole string of these.
- Final Fantasy XIII and sequels: Lightning says that she changed her name to Lightning in one scene in FFXIII, and her original name is only given twice in three games: once in FFXIII, and once more in Lightning Returns: Final Fantasy XIII. It's Claire in English, and Éclaire in Japanese.
- The Reveal that BrotherSister Incest is going on in No More Heroes is so obscured that it's only possible to comprehend if you record the video output from the Wii and slow it down in video editing software.
- In RWBY during generally hilarious scene when Nora consideres the consequences of JNPR losing first battle in the tournament there is hidden gut punch when she mentions that she and Ren are orphans
- In the Strong Bad Email the chair, Strong Bad taunts the audience by randomly pulling out a supposed picture of his parents, which is almost completely obscured by the screen-filling back of his new chair. However, decompiling the Flash reveals nothing on the photo but the message "nice try dodongo!"
- In El Goonish Shive, Sarah's last name (Brown) was revealed in this manner; the principal used it to refer to her while rebuking her for breaking the dress code.
- This was standard practice in the early run of Gunnerkrigg Court. At the end of each chapter was a bonus page, giving details of the school and surrounding areas.
- In the movie of Fantastic Mr. Fox, there is much fun had with the conversion between fox years and human years (a 6:1 ratio), though a specific year for the movie's events is never given: it can, however, be extrapolated from Ash's age, Mr. Fox's age and the years we see on a trophy (1973, in case you were wondering).
- Gargoyles has Demona capture the mythological trickster, Puck; and she threatens him "You serve the human, now you can serve me." Puck's response is "Serving humans is fun; they have a sense of humor. You have none." - distracting the audience from the fact that Demona referred to the human that Puck serves, which soon becomes a plot point.
- The Iron Giant makes no mention of what happened to Hogarth's dad, but during Hogarth's standoff with Kent, a picture of a fighter pilot is seen on his nightstand, and the audience is left to fill in the blanks.
- Yellow Submarine: The animators almost seem to deliberately distract you when Fred accidentally drops all of the instruments in the Sea of Monsters, and the Beatles don't even mention it until they reach Pepperland. The only hint before that is when the Beatles play air instruments during the Nowhere Man sequence.
