->'' 'You are beautifully and perfectly balanced. In you sanity is personified. Do you realize what that means to me? When the criminal sets out to do a crime, his first effort is to deceive. Whom does he seek to deceive? The image in his mind is that of the normal man. There is probably no such thing actually -- it is a mathematical abstraction. But you come as near to realizing it as is possible... how does this profit me? Simply in this way. As in a mirror I see reflected in your mind exactly what the criminal wishes me to believe. That is terrifically helpful and suggestive.' ''
-->-- '''Literature/HerculePoirot''' to his Watson: Captain Hastings, ''Lord Edgware Dies''

The Watson is the character whose job it is to ask the same questions the audience must be asking and let other characters explain what's going on. Distinct from MrExposition in that The Watson is TheStoryteller archetype, and often allows another character to become MrExposition within the story's context.

Generally, female variants of The Watson will have a bit more CharacterDevelopment and a larger role within the story (but not too much larger). She will be inevitably attractive, serving a dual role -- giving the children someone to like and the [[ParentService adults someone to tune in for]].

Children have it easier. ConstantlyCurious is a popular device, and may even force MrExposition into that role.

Playing The Watson is also referred to as cabbaging, since this role could be played by a head of cabbage.

Science fiction fans may know this character as The Sarah Jane, after (arguably) the most popular of the many companions who had things explained to them on ''Series/DoctorWho.'' In fact, actress Louise Jameson, who played another of the Doctor's companions, explained her decision to leave after a relatively short tenure as being motivated by the fact that, "There are only so many ways you can say 'What is it, Doctor?'"

On occasions, you get The Watson being cleverer than MrExposition, which results in some problems, but occasionally works.

Often in fantasy settings, The Watson is the character with more [[OnlySaneMan "real world" sensibilities]] (sometimes because he's been transplanted ''from'' the real world: John Crichton (''Series/{{Farscape}}'') often got to act as The Watson in early episodes, for example; other times they're an everyman among a group of specialised professionals), prompting MrExposition to explain the "rules" of the fantasy world.

In parody, it is becoming increasingly common for The Watson to be a character who isn't {{genre blind|ness}} to the sillier tropes, often making MrExposition look like something of a buffoon (as in ''Film/AustinPowers: International Man of Mystery'', where Scott Evil [[StatingTheSimpleSolution asks why his father]] [[WhyDontYaJustShootHim doesn't just shoot Austin]], instead preferring to put him in an easily escapable DeathTrap). See GenreSavvy.

Aside from serving as an AudienceSurrogate, the Watson can also play an important but often overlooked role in the story itself. As many of the examples show, the Watson's comments and actions often help the detective in figuring out the mystery. While the Watson may not be able to solve the cases himself, he often gives the detective the final crucial insights that point him in the right direction.

See also TheSnarkKnight, who makes similar observations but is much less inclined to assist afterwards.

Sometimes The Watson will overlap with FirstPersonPeripheralNarrator, which is when the story is narrated by someone other than the main character of the story.

Has nothing to do with the ''Series/{{Jeopardy}}''-winning IBM supercomputer of the same name, awesome as it is. Except that they both usually speak in the form of a question.

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* We rarely ever get a first-person perspective on ''{{Akagi}}'''s thoughts - as the point of view is mainly given to Yasuoka (oddly enough a detective), who observes and attempts to decrypt Akagi's genius from the sidelines.
* In ''Manga/DeathNote,'' Ryuk, a {{shinigami}}, often acts as The Watson to Light's plans. That is, when he's not just standing behind Light silently chuckling. Or standing on his head.
** Touta Matsuda in the same series is used as The Watson for the police side of events, mainly due to his being a male version of TheDitz.
** Amnesia!Light and Watari are also this to L, being just different ages in Watson.
* Manta Oyamada in ''ShamanKing'' acts as The Watson to Yoh Asakura, being the narrator but not TheHero.
* Hiyono in ''{{Spiral}}'' tends to get dropped into this role, and if she isn't, Kousuke is. Hiyo-Hiyo is reasonably clever, and Kou-chan even more so, but that doesn't say much when the entire main cast is made up of child prodigies.
* Rick Wheeler/Ryu Suzaku in ''VideoGame/{{F-Zero}}: Falcon Densetsu''. (You know this show as the one that [[AscendedMeme Ascended]] '''[[MemeticMutation "FALCON PUUUUUUUNCH!!!"]]''')
* Normally intelligent Chachamaru in ''Manga/MahouSenseiNegima'' was always and entirely uninformed of any fighting style during the Mahora Tournament. Giving us [[MrExposition Explainer]] Goutokuji for this portion of the series. Normally Asuna, Nodoka, Konoka, and Chisame serve this purpose. Yue bounces between this and MrExposition depending on where in the series you are. When it comes to fighting Negi takes this role, giving the big Exposition talk to Kaede (Ninja), Ku Fei (Kung Fu Master), Kotaro (Dog Demon Brawler Ninja), or Evangaline (Really Old Vampire).
* Despite being from the same magical world as everyone else, Gourry from ''{{Slayers}}'' was enough of an idiot to have to ask questions about what the other characters would consider basic, everyday facts, giving them a reason to explain the rules and mythology of their world.
** In the original {{Light Novel}}s the anime is based off of, protagonist Lina herself is the [[FirstPersonSmartass narrator]] and Gourry, while still uninformed, is no where near as idiotic.
* The titular character of ''Manga/{{Naruto}}'' frequently had to play this role early on, being a shining example of BookDumb. It's almost mystifying that ten episodes in you'll probably know more about the geography, FunctionalMagic, and infrastructure of the story's world than he did ''when he graduated''.
* Akari from ''Manga/{{ARIA}}'' has some of this. Alicia could have picked a local girl for an apprentice, but instead she chose someone who needs a lot of explanations about the planet she moved to--which then of course raises the question why Akari didn't read a travel guide beforehand.
* ''Manga/DetectiveConan'': Depending on the case, and which characters are present at the time, any number of characters will play Watson to Conan's Holmes... Ai, the Detective Boys, Ran, the cops, Eri, Jodie, etc. Conan pretends to be The Watson to Kogoro (the only ''professional'' detective in the series), even though he is invariably the one solving his cases for him.
** On the evil side, Vodka plays Watson to Gin. Since Gin is both smarter and higher-ranked than his partner, he often has to explain his plans and the Organization's to Vodka and thereby the audience.
* Kuwabara from ''Manga/YuYuHakusho'' is the guy who asks the questions so that Hiei and Kurama can avoid having to use AsYouKnow when being MrExposition. When he got PutOnABus in the final season to pursue a higher education, the anime attempted to spread this role out amongst the other characters; it didn't work out too well.
* Elsee in ''Manga/TheWorldGodOnlyKnows'' is often asking why Keima is doing what he is doing. The explanations, however, are not always comprehensible (and are often funny because of that).
* Roji tends to play this role in ''MuhyoAndRoji'', often about the workings of magical law or Muhyo's past. Other times, the clients ask the questions.
* Kotori Mizuki of ''Anime/YuGiOhZEXAL'' is this in regards to the card game.
* Nonoha in ''Anime/PhiBrainKamiNoPuzzle'' serves this role as the rest of the main cast are puzzle-solving geniuses, so she gets to stand in for the audience and ask any questions needed about the various puzzles they are confronted with.
* In ''Manga/{{Bakuman}}'', Takagi served this role in the first volume, asking Mashiro about how the manga industry worked (Mashiro happened to have a mangaka uncle). Later on, Miyoshi filled this role as the characters became more familiar with the industry.
* Mahiro Yasaka from ''LightNovel/HaiyoreNyarkoSan'' gets to play an odd combination of Watson and MrExposition thanks to his unique position in the story. As an OrdinaryHighSchoolStudent, he needs explanations about the aliens he and Nyarko encounter; however, as a fan of the CthulhuMythos, he can exposit a little about what said alien is within the context of Lovecraft's works once Nyarko has given him a name to work with.
* Jigen serves this role to Lupin during ''Anime/LupinIIIDeadOrAlive''. It's as if Jigen was waiting until the two are actually trying to steal the national treasury before he learned what was going on. Considering his laid-back personality, that may be exactly what happened.
[[/folder]]

[[folder:Comic Books]]
* Comicbook/{{Robin}}, and to a lesser extent Alfred tend to play this role to ''Franchise/{{Batman}}''. This is even part of the reason Robin was created.
* Rick Jones of various Creator/MarvelComics sidekick roles. Though sometimes his leading Hero would be the Sherlock, sometimes various experts would be the Sherlock, but most commonly after getting captured, MrExposition would be [[JustBetweenYouAndMe the one who was supposed to be interrogating]] ''him''.
* Crispus Allen plays the Watson in the early issues of ''ComicBook/GothamCentral'', and occasionally later on. As a transferred officer from Metropolis, Allen did not have extensive experience with the "freaks" (supervillains) of Gotham City, so other characters would explain their means and methods to him, [[MrExposition simultaneously infoming the audience as well]]. This particular facet of his character was dropped after a few issues, when he already had his own personal experiences with the [[RoguesGallery rogues]] of the city, but he would later serve as the Watson on more complex issues when characters needed to highlight personal and societal points about Gotham City itself, such as the reason why Franchise/{{Batman}} is important to Gotham for more than just the crimes he stops.
* Once she learned his secret identity, [[SpiderMan Peter Parker's]] [[ComicBook/OneMoreDay wife]], Mary Jane [[strike:Watson]] [[strike:Parker]] Watson occasionally served this role for him, asking him things about the superhero business. One of the best examples of her being used in this fashion was in the story ''Hobgoblin Lives!'' where Peter had to fill her in on the background for the story (since the stories it happened in were written ''years'' ago) and she asked the simple question that led to a plot breakthrough.
** Unintentional StealthPun there.
** Tee hee, and her name is WATSON.
* In ''Comicbook/DoctorStrange: The Oath'', Night Nurse is along for the adventure at her own insistence (Strange has been wounded and she is a physician). Strange's assistant Wong is also present as a sort of minor Holmes/experienced Watson, answering some questions and asking others.
* ComicBook/UsagiYojimbo: Inspector Nii sometimes serves as this to Ishida, who needs to explain the situation. Other times he explains if to Usagi or a superior.
[[/folder]]

[[folder:Fan Works]]
* In ''Fanfic/{{Luminosity}}'', Bella sets up some scientific experiments to prove that the Cullens are really vampires...and once she's convinced she's just fascinated with the fact that they ''exist'' and generally tries to learn more. About everything.
* In ''FanFic/TheTaintedGrimoire'' Luso, and to a lesser extent Hurdy, get things they don't know about explained to them by other characters.
* In the ''FanFic/TamersForeverSeries'', DC fills this role around Gabrielle during ''Silent Sorrow''.
* ''WebAnimation/TurnaboutStorm'': [[VisualNovel/AceAttorney Phoenix]] plays this role everytime [[WesternAnimation/MyLittlePonyFriendshipIsMagic Equestria]] and its workings get involved or are discussed. As a character from a mostly realistic setting, he casts doubt on and asks the same things viewers unfamiliar with the ''Friendship is Magic'' series would.
[[/folder]]

[[folder:Film]]
* The narrator of ''Film/DasBoot'' acts as both Watson and MrExposition. He's on board as a journalist, thus it's his job to be inquisitive about everything, and pass on his knowledge. He has naval experience on surface ships but this is his first voyage on a submarine. The crew and officers sometimes pause to explain what they're doing to him but he often has to figure it out by observation.
* Jack Ryan in ''Film/TheHuntForRedOctober'' plays TheWatson for all the submarine action, letting the boat captains play MrExposition. Similarly, Seaman Beaumont plays TheWatson for sonar terms, letting Sonar Technician Jones explain everything.
* In the DVD commentary for ''Film/{{Ghostbusters}}'', Ivan Reitman says the character of Winston Zeddemore was intended to serve this purpose.
* Marty [=McFly=] fills this role from time to time in ''Film/BackToTheFuture'' so Doc can explain some of the time travel mechanics.
* Massively subverted by Donnie in ''Film/TheBigLebowski'', who is utterly LockedOutOfTheLoop.
-->Forget it, Donnie, you're out of your element!
* In the movie ''Film/FantasticVoyage'', and in the Creator/IsaacAsimov [[Literature/FantasticVoyage novelization]], TheWatson is secret agent and former combat swimmer Charles Grant. Asimov's version makes him a bit less of a dunce; on occasion, Grant can actually figure something out from his general knowledge of human anatomy, instead of needing the knowledge spoonfed to him.
* The ''Franchise/{{Terminator}}'' series has one of them for every episode:
** ''The Terminator'': Sarah Connor
** ''Terminator II'': John Connor
** ''Terminator 3'': Kate Brewster
** ''Terminator: Salvation'': Marcus
* Averted by Watson from the 2010 ''Film/SherlockHolmes'' film. He is less Watson-y than Watsons from almost any other adaptation and shows intuitive and deductive skills which he picked up from his time working with Holmes. This is truer to the original Watson: a skilled and intelligent medical practitioner, decorated war veteran, and good man in a brawl.
* On the other hand, Nigel Bruce pretty much created the "Bumbling Watson" stereotype when he was teamed with Basil Rathbone's sharp and decisive Holmes in 1940s film and radio. Even so, in the radio series Bruce's Watson was given a few occasions to explicitly show that, while he was a lousy detective, he was an extremely competent doctor, able to diagnose medical problems as quickly and easily as Holmes could deduce anything else.
* John Myers in the first ''Film/{{Hellboy}}'' movie, especially since no such character exists in the [[ComicBook/{{Hellboy}} comics]].
* James Edwards/Jay in ''Film/MenInBlack''.
* Dr. Karen Jenson in the first ''{{Blade}}'' film. She's left out of the remaining series because there's no need for her anymore.
* Vittoria Vetra in the film adaptation of ''AngelsAndDemons''. Thanks to editing for time constraints, it's pretty much all she's there for.
* Ariadne in ''{{Inception}}''. She asks the questions about inception and extraction that the viewer would be asking. Saito is also this to some extent, at least in the beginning of the film.
* ''Film/{{Apollo 13}}'': Jim Lovell's youngest son, Jeffrey, asks his father about his upcoming mission, i.e. how long it'll take to get to the moon and the function of the lunar module. Jim also explains what went wrong in the Apollo 1 disaster, briefly depicted in the beginning of the movie.
* ''Film/{{Thor}}'s'' Darcy asks genius astrophysicists Jane and Erik to translate their {{Technobabble}}. A role enthusiastically taken up by CaptainAmerica in ''Film/TheAvengers'' for [[IronMan Tony]] and [[TheIncredibleHulk Bruce]].
* WordOfGod says that [[CanonForeigner Wybie]] was added to the ''{{Film/Coraline}}'' [[FilmOfTheBook film adaptation]] because, unlike [[{{Literature/Coraline}} the book]], a movie can only exposit through spoken words; they just didn't want [[PluckyGirl Coraline]] to be wandering around talking to herself. It works both ways, since Wybie provides her with exposition about the house and the disappeared children. Also, the fans love him because he's {{Adorkable}} and the two kids have moments of ShipTease.
[[/folder]]

[[folder:Literature]]
* The trope namer is Dr. John Watson, the narrator from the ''SherlockHolmes'' stories by Arthur Conan Doyle, who often asks the title character to explain his baffling logical leaps. Holmes then explains the logic used in solving the case, allowing the author to describe the finer points of the story without disrupting the narrative flow. Unlike the character found in some lesser adaptations, Watson is not a chubby dullard, but a very intelligent and bold man who occasionally contributes his own observations to cases, though he is not always completely correct. Holmes often makes use of Watson's medical knowledge and fresh perspective to keep his deductions sharp. In ''A Study In Scarlet'', a puzzled Watson rattles off all the unanswered questions about the case, and Holmes commends him for pointing out the main difficulties. It's implied that Holmes is glad to have someone who he can fruitfully discuss the case with, which is more than can be said for [[PoliceAreUseless Inspectors Lestrade and Gregson]]. Holmes even acknowledges Watson's importance in providing him with critical insights, saying, "...you are not yourself luminous, but as a conductor of light, you are unparalleled!"
** In a few comments and the stories written from Holmes' own perspective, it's revealed that Watson intentionally leaves elements he noticed himself out of the stories just to make the reveal at the end more surprising to the reader, a practice that greatly annoyed Holmes.
** In fact, Watson often ''doesn't'' act very much as TheWatson (i.e., asking Holmes to explain what's going on throughout the plot) because Holmes usually dislikes explaining his reasoning as he goes -- the stories' mystery often hinges on the fact that we (and Watson) have no idea what's going on in Holmes's head. Watson usually either a) picks up on it himself and explains it to the readers via narration or b) wryly notes that Holmes is loathe to explain his conclusions until he's sure he's right, and just follows along patiently waiting for him to solve the puzzle. The "Watson" trope is most likely derived from film adaptations, where Watson's narration in the books understandably needed to be replaced with dialogue, or from the books' various famous prelude scenes in which Holmes drops some near-telepathically-accurate deduction about Watson's personal affairs out of the blue, and an astonished Watson asks him to explain how the hell he knew that.
* Captain Hastings in several of Creator/AgathaChristie's Literature/HerculePoirot stories, on the other hand, was most definitely TheWatson -- in fact, he resembled the [[{{Flanderization}} flanderized]] Watson more than the original Watson did. The context of the page quote is that Poirot is refuting Hastings' belief that he has learned a lot from him, as he doesn't want or need Hastings to be a second-rate Poriot (a contrast with the numerous occasions that Watson does correctly deduce something using Holmes' methods, or figures out the source of a deduction Holmes made a moment earlier.) He readily {{lampshaded}} this fact too, calling himself "the humble Watson" in jest.
** Dr. Sheppard fulfills this role in ''Literature/{{The Murder of Roger Ackroyd}}'' when [[Literature/HerculePoirot Poirot]] is on a BusmansHoliday. [[spoiler: However, it turns out he's the killer.]]
* Most stories about a {{Utopia}}, particularly those written before the mid-twentieth century, tend to feature a lead character who is a Watson combined with a NaiveNewcomer. The plot generally consisted of the Watson being led around the utopia asking questions about how it works. The ExpositionFairy who lived in the utopia would then explain how the utopia worked in exhaustive detail. Really poorly thought out utopian novels ''did not'' combine this trope with the NaiveNewcomer and hence had the ExpositionFairy tell TheWatson things they already knew for no apparent reason. Generally declined in usage after modern exposition techniques, (ie "Show, Don't Tell") were developed. Examples include Julian West from ''Looking Backward''by Edward Bellamy, Guest from ''News from Nowhere'' by Creator/WilliamMorris, and the Botanist from ''A Modern Utopia'' by H. G. Wells. An example of a Watson who ''isn't'' combined with the NaiveNewcomer is Alice from ''Ralph 124C 41+'' by Hugo Gernsback.
* In the ''Literature/AubreyMaturin'' series, Stephen Maturin acts as a Watson in all matters nautical, conveniently (for the reader) refusing to learn to tell one sail from another however long he lives on a ship.
* Often, the limitations or rules of {{Deryni}} magic are explained in answers to questions posed by characters who are ordinary humans or otherwise inexperienced:
** As the coronation duel unfolds in ''Deryni Rising'', Nigel fires a series of anxious questions at Morgan and Duncan. Nigel is particularly disturbed at the tactical "mistake" of giving Charissa the first blow, but [[MrExposition Duncan explains]] that [[DoubleStandard allowing a woman the first blow, even if she issues the challenge, is one of the rules]].
** The younger Kelson, especially in the first year or so of his reign, was tempted to use his powers directly against the archbishops (Loris and Corrigan) who were undermining his government by persecuting Deryni generally and Morgan in particular. Morgan and Duncan must remind him (and the audience) why such a direct to route towards conflict resolution is no solution.
** Derry asks key questions about the distance and using the spell when Morgan teaches him to join in long-distance rapport for his first reconnaissance trip in ''Deryni Checkmate''.
** Early in ''The Bishop's Heir'', Dhugal is present when Kelson uses his powers to question a sleeping Caulay [=McArdry=], and more questions follow when Kelson breaks off to answer Morgan's distant Call and needs Dhugal's help to establish so distant a mental contact.
** Kelson reverts to being the questioner when working with Prince Azim Hur Hallaj to prepare for his role as a Moving Ward for Liam's killijálay in ''King Kelson's Bride''.
* In Umberto Eco's ''Literature/TheNameOfTheRose'', Adso (the narrator) is the assistant of a Medieval detective named William of Baskerville, and inquires into the latter's deduction methods as the reader would. [[MeaningfulName Unsurprisingly]], both characters were inspired by Watson and Sherlock Holmes.
* In ''TheThrawnTrilogy'' Captain Pellaeon serves as the villainous ([[AffablyEvil somewhat]]) Watson to Grand Admiral Thrawn. He's also the best possible versions of CommanderContrarian and a protege.
** Definitely a protege. In the [[HandOfThrawn later duology]], he may not reach Thrawn-levels of skill, but his tactical sense and intuition have clearly been honed.
** Interestingly enough, official artwork shows that he actually ''[[http://images.wikia.com/starwars/images/6/69/PellaeonYVW.jpg looks]]'' kind of like Watson-- or at least the Watson played by [[http://www.youtube.com/watch?v=eBI_5Rzf1aI Edward Hardwicke]]. Which rather fits, as it's easy to imagine Jeremy Brett with blue skin and glowing red eyes as Thrawn.
* In the ''Literature/HonorHarrington'' series, Haven's [[ReignOfTerror Committee for Public Safety]] stations a PoliticalOfficer on each ship to watch over (a.k.a. second guess) naval officers. They play a darker version of this trope because captains often have to explain and justify their decisions to people with no military training while avoiding any appearance of disloyalty to a regime that [[YouHaveFailedMe executes captains to fail to carry out their orders]] [[DisproportionateRetribution and their whole families]].
* [[Literature/InheritanceCycle Eragon]] is always asking questions, [[LampshadeHanging to the point where a description of him one character gives to another includes "always asking questions"]].
* ''Literature/HarryPotter''
** Ron was constantly making suggestions, forcing Hermione to sigh and explain that, if only he'd read ''[[GreatBigBookOfEverything Hogwarts: A History]]'', he'd understand why it's impossible to... Rowling said she would never have Harry or Ron read ''Hogwarts: A History'' because it was too useful an expository device.
** Harry is just as much of a Watson as Ron, albeit one who serves a different purpose. Having grown up with Muggles, there's a lot he doesn't know that people who grew up in the wizarding world would take for granted (Quidditch? What's that, some kind of illness?). Ironically, it's often Ron who gets to be Mr. Exposition in those situations, since unlike Hermione, he grew up in the wizarding world, and is therefore the only one of the main trio to have that sort of knowledge.
** And EVERYBODY is this trope for [[TheChessmaster Albus Dumbledore]]. There's a [[InfoDump "Dumbledore Explains It All" scene]] at the end of every book, except the sixth when it's not at the end. There's even one of those scenes in [[Literature/HarryPotterAndTheDeathlyHallows the last book]], ''[[SpiritAdvisor even though Dumbledore's dead at the time.]]''
** A minor example is [[CameraFiend Colin]] in ''Literature/HarryPotterAndTheChamberOfSecrets'' -- his opening scene is spent following Harry around asking him questions, allowing him to briefly explain Quidditch rules to anyone who didn't read the first book.
* TomSwift generally has one of these on hand. In the "[[http://tomswift.bobfinnan.com/ts2.htm Tom Swift, Jr.]]" series of books published in the 1950s, it was Bud Barclay. The RecycledINSPACE! series which followed in the early 1980s had Benjamin Franklin Walking Eagle. One ContinuityReboot later, TheWatson was Rick "test to destruction!" Cantwell.
* Archie Goodwin, Watson to Literature/NeroWolfe's Holmes. Archie is a capable detective in his own right, and would frequently figure out the murderer just as Wolfe does. Since he writes his "reports" for an audience, however, he usually doesn't let the reader in on it until Wolfe explains the mystery.
** Like Watson, Archie frequently gets [[{{Flanderization}} flanderized]] into a dull-witted womanizer in adaptations, with only his outstanding memory being kept.
* In Creator/RobertEHoward's ConanTheBarbarian story "Beyond the Black River," Balthus. Conan repeatedly explains his acts, both how and why, to him.
* Both played straight and parodied/heavily lampshaded in Creator/AAMilne's ''The Red House Mystery'', where the AmateurSleuth Anthony outright asks his friend Bill to play Watson to his Holmes, specifically defining Bill's role as asking stupid questions and needing even the most obvious things explained to him. And indeed, this is what Bill does -- but half the time he's asking the questions because Anthony tells him to rather than because he's actually incapable of figuring out the answers, and sometimes he gets fed up with his friend's Sherlockian pretensions.
* In the ''Literature/SimonArk'' short stories, Simon's publisher (who is also the narrator of the stories) fills this role.
* A variety of characters fill this role for Horne Fisher, the central character of Creator/GKChesterton's ''The Man Who Knew Too Much''.
* The naive but pure-hearted Ten Ox plays this role to the cunning and knowledgeable sage Li Kao in ''Literature/BridgeOfBirds''. There's actually an early draft of the book that reveals the author had originally intended for Li Kao to be the narrator and Ten Ox to be only a peripheral character. Comparing this draft with the final product shows just how much the promotion of Ten Ox to this character role (and the addition of many plot elements) improved the book; for one thing, Li Kao's narration of his life story isn't quite as effective when he tells it in a drunken ramble to a skull in a pool as when he tells it to Ten Ox to assure him that he's not going to give up in his quest to heal the ill children of Ten Ox's village.
* Detective Sergeant Mary Mary in the ''NurseryCrime'' novels is a pastiche of the trope in British detective drama. Coming from outside the area she's somewhat GenreBlind to the mixture of detective and nursery rhyme tropes that dominate Reading, so DI Spratt has to clue her in on this as well as explaining the case to her.
* Peter plays this role in ''PeterAndTheStarcatchers''. There's a whole chapter where Molly has to give him a long CharacterFilibuster to explain the history of the Starcatchers.
* [[Literature/JeevesAndWooster Bertie Wooster]] sometimes has to grill Jeeves at great length to figure out what, exactly, is going on. BonusPoints because Creator/PGWodehouse was a big ''SherlockHolmes'' fan and occasionally threw in a reference to the characters.
* Sister Fidelma, Irish nun and law official in the books by Peter Tremayne, has the Saxon monk Brother Eadulf, later her husband (which was allowed in the Celtic Church). In some of the stories where Eadulf doesn't appear, Abbot Laisran serves the role, creating an interesting dynamic since he's her superior in the church, but not in the courts.
* In the ''TabletopGame/MagicTheGathering'' novel ''Literature/TestOfMetal'', Doctor Jest often serves this purpose, giving Tezzeret someone to converse with and explain things to when the story demands it.
* Many [[{{UsefulNotes/Buddhism}} Buddhist]] sutras are framed as a dialog with a disciple, usually Sariputta, asking Siddhartha questions that were or would be asked by others trying to understand.
* In David Pirie's ArthurConanDoyle / Joseph Bell mysteries, Doyle plays TheWatson to Bell's SherlockHolmes. However, this is also a subversion: Doyle is not less intelligent than Bell, just decades younger, and their working relationship is often TeethClenchedTeamwork instead of friendly.

[[folder:Live Action TV]]
* In ''Series/{{Monk}}'', Sharona Fleming (season 1-season 3) and Natalie Teeger (season 3-8) are this to Adrian Monk.
* In ''MagnumPI'', Magnum had an annoying friend named Rick. His function in the series was to serve as a sort of surrogate for the audience on the more outrageous story points. He was always protesting, "C'mon, Magnum..." as in, "C'mon, Magnum, there's no way those crooks would trust us with $7 million in gold coins. It's ludicrous." (And this is exactly what the audience was thinking at that point.) Magnum would then calmly explain to Rick just exactly why the crooks would, indeed, hand over $7 million in gold. Rick would be convinced, and in theory, the audience protests would have been addressed as well.
** This page was, it should be noted, once named TheRick.
* The classic (1963-1989) series of ''Series/DoctorWho'' featured countless characters that filled this role. The female companions evolved as the series went on, tending more towards the ActionGirl; the last before the series was cancelled was Ace, a punk-rock teen who loved explosives and was willing to rush at a Dalek with a baseball bat if she saw one.
** In one ep (just after he's 'lost' another one), the Doctor starts babbling to thin air, and then stops cause he realizes no one's listening.
** Funnily enough, Sarah Jane herself gets her own Watsons in ''Series/TheSarahJaneAdventures'', in the form of Maria, Luke and Clyde (and later Rani). In this show it's the boys, and not Maria, who tend to get captured more often... though they are still savvy enough to get themselves out of it too.
** In the newer episodes of ''Series/DoctorWho'', the Doctor himself is often TheWatson, asking the natives of whatever time and place he's landed in [[WhatYearIsThis what's going on]] and [[ArmorPiercingQuestion why they're doing what they're doing]].
** Parodied in the MitchBenn song [[http://www.youtube.com/watch?v=m1QgCx1CIaQ "Be My Doctor Who Girl"]]:
---> Be my Doctor Who girl, follow me a lot\\
Ask me heaps of questions\\
So I can explain the plot
* Gwen gets to fill this role on ''Series/{{Torchwood}}''.
* On ''Series/{{House}}'' the role of House's Watson is played by ''every single character''. One memorable example had House saying his staff's diagnosis was wrong, because they weren't wearing the right shoes -- if the diagnosis was right, they'd all already be at a bowling alley.
** Since Gregory House is heavily based on SherlockHolmes, James Wilson is the main analogue to John Watson.
** Once when House was separated from his regular Watsons, he drafted three random travelers and a janitor to serve as Watsons in a pinch. The janitor suggested [[MemeticMutation Lupus]] as a possible diagnosis.
* Every single character in every single episode of every single ''Series/{{CSI}}'' can be the Watson. They find some rash or bacteria or wound or something on the corpse and then go on explaining what that means to the nearest character. Since that character is [[AsYouKnow supposed to know that stuff as well]], the whole dialogue turns into a circus of finishing sentences for the other character.
** In Grissom's last episode, Hodges says he's Watson to Grissom's Holmes. Grissom reminds him that Watson was a genius in his own right.
* The [[TheDitz ditzy]] lab assistant in the "Science Fiction Sketch" on ''Series/MontyPythonsFlyingCircus'' is very much a parody of the type; she exists simply to look pretty and have Graham Chapman's character explain the plot to her. He eventually becomes so frustrated with her stupidity that he knocks her out and explains the plot to himself instead.
* Gus from ''{{Psych}}'', one of the few characters in on the {{Masquerade}}, whose fair intelligence and relative lack of observancy make him just short of an {{Expy}} of Watson himself. The gap between his character and Expy status closes even further when you consider how often his pharmaceutical knowledge (an update of Watson's medical training) plays into solving cases.
* In ''Series/RedDwarf'', the Cat, Lister and Rimmer tend to share Watson duties, with Holly and Kryten acting as MrExposition. This becomes extreme in the scene explaining the stasis leak, where Cat has to ask "What is it?" four times to get simpler and simpler explanations.
* In ''Series/{{Lost}}'', it's Hurley. Officially; it was lampshaded by the executive producers in a podcast.
* Clark Kent from ''{{Smallville}}'' fits this in that he's usually the one giving Chloe an opportunity to rattle off a short explanation of whatever clever trick she came up with. Bonus points if Clark wears his [[FanNickname Big Dumb Alien]][[TradeSnark ™]] expression to complete the cliche of Watson being a bit slow.
* Applies to Maddy, Carla and now Joey in ''Series/JonathanCreek''.
* Whenever somebody in ''Series/StargateUniverse'' explains something about how the Stargates function, they're explaining it to Eli. He's by far the least experienced of the bunch, though arguably more intelligent than most of the people explaining stuff to him.
** Jack O'Neill of ''Series/StargateSG1'' was the same. While a ColonelBadass and good leader, he'll still have to ask the two geniuses or the alien about whatever bit of AppliedPhlebotinum is about. Whether or not he was portrayed as ''generally'' unintelligent, or merely needing to leave [[RememberWhenYouBlewUpASun blowing up suns]] to Samantha Carter, wavered. Seldom if ever did Jack O'Neill fail to grasp what was going on. He was just a huge fan of ObfuscatingStupidity and had little patience for TechnoBabble.
* The core cast of ''{{Lexx}}'' had a pretty clear division between Holmeses and Watsons. Kai was 2000 years old with thousands of strangers' lifetimes in his memory, 790 was a robot with knowledge of every sector in the universe (and wireless internet directly to his brain), and Stan and Xev were illiterate fugitives from a world where humans lived in boxes and were taught nothing more than needed to do their jobs. They not only needed explanations for PolarityReversal and [[http://en.wikipedia.org/wiki/Star_lifting star lifting]], but also for concepts like ''books.''
--> '''Kai''': Books contain useful information... sometimes. And interesting stories... less often.
* Illya Kuryakin played TheWatson at the climax of the third season ''TheManFromUNCLE'' episode "The Five Daughters Affair, Part II":
-->[''THRUSH operative Randolph, having gotten Dr. Simon True's seawater-to-gold extraction formula away from U.N.C.L.E., is gloating before Solo and Kuryakin'']
-->'''Randolph''': Imagine, tons of gold, tons! Pouring into our storage vats. [''Kuryakin raises his hand''] Yes?
-->'''Illya Kuryakin''': Won't this Midas-land master plan defeat its own object? [[WorthlessYellowRocks With gold as plentiful as dust, won't it lose its value]]?
-->'''Randolph''': We will control its rate of release, don't you worry.
-->'''Napoleon Solo''': We won't.
* Wallace Fennel is the Watson to ''VeronicaMars'', especially at the start of season 1, since he is new to Neptune.
* Donna usually played this role in ''TheWestWing'', at least in the early years. Her job was to badger Josh with all the questions the audience was asking, "But Josh, why is policy x important?" "Josh, why should we loan Mexico millions?" In the later seasons she received CharacterDevelopment and moved beyond this role, occasionally needing her own Watson.
* Booth to Brennan in ''Series/{{Bones}}'', though it could argued that they really ping-pong the role between them depending whether they're dealing with the forensic or detective aspect of the investigation. But when you consider Booth's past as a soldier in the Middle East and the fact that Brennan is a doctor consulting to law enforcement you can clearly see their fictional lineage. The Squints are unquestionably the Baker Street Irregulars.
* The police with whom the BAU team up in ''Series/CriminalMinds'' often serve this purpose. Each episode has a scene where the team deliver a profile explaining the killer's psychology to the police, and thus also to the audience.
** Occasionally subverted when the cops grab the wrong end of the stick and completely misunderstand the profile, or think about it and realize it applies to half the local population.
* On ''Series/TheATeam'', Face was usually this to Hannibal when he explained that episode's plan, bringing up potential snags and problems that they could run into, but Murdock, B. A., and/or (in the early seasons) [[TheChick Amy or Tawnia]] could fill this role instead or simultaneously.
* In ''PrisonBreak'', Sucre was TheWatson to Michael during the first season. Lampshaded by the actor, who commented on how his main role in the plot was to ask Michael "what are you doing?" or "what do we do next?" In later seasons, this role would fall to whoever happened to be with Michael at the time, such as Lincoln and Sara. Mahone also had his own Watson during season 2, but since Mahone was a baddie at the time, it didn't quite play out the same way.
* Tori Vega in ''{{Victorious}}'', as a NewTransferStudent who is a talented musician but untrained, is this with her asking questions that the rest of the cast can then explain what certain theatrical or musical plot relevant terms mean in case the audience don't know.
* Teresa Lisbon to Patrick Jane in ''TheMentalist''.
* In ''Series/{{Eureka}}'', [[TheSheriff Jack Carter]] is the Watson to most of the other characters in rapid succession so they can all have a go at explaining the [[MonsterOfTheWeek current threat]] and science behind the [[AppliedPhlebotinum solution]].
* Daphne played this sort of role in ''{{Frasier}}'', asking the Cranes to explain what the hell they were talking about whenever they got involved in something pertaining to their younger years or family affairs (which was many, many episodes). This was so the Cranes would have a legitimate reason to tell a hasty expository story that they all already were clear on about their past so the audience knew what the problem they had this time was. Roz occasionally fulfilled this role too.
* On the BBC modernisation of the TropeNamer, Series/{{Sherlock}}, this role is filled by Doctor John Wat-[{{Beat}}] [[CaptainObvious Ah. Right.]] He didn't replace a head of cabbage though, [[spoiler:he replaced a skull]].
-->'''John''': ''How''--[[LampshadeHanging Oh, never mind]].
** This mean-spirited bit of dialogue sums it up:
-->'''John''': I don't understand.
-->'''Villian of the Week''': You should put that on a t-shirt. ''[continues to explain]''
* Every UK detective drama features a stolid Detective Sergeant or Constable who the Detective Inspector can explain things to.
** InspectorMorse had Sergeant Lewis, then Inspector {{Lewis}} had Sergeant Hathaway.
** DCI Jim {{Taggart}} had DS Michael Jardine and DS Jackie Reid, then DCI Jardine had DS Reid and DC Stuart Fraser. Currently DCI Matthew Burke, DI Reid and DI Robbie Ross have DS Mita Rahim.
** ''Series/MidsomerMurders'': DCI Tom Barnaby had Sergeant Troy, replaced first by Sergeant Scott and then by Sergeant Jones, who continues to serve as the Watson to Barnaby's SuspiciouslySimilarSubstitute cousin, DCI John Barnaby.
** DI Jack Frost of ''Series/ATouchOfFrost'' has a rotating cast of sidekicks. The most prominent ones are DS Hazel Wallace and DS Clive Barnard.
** The ITCH episode of Neveneffecten is a play on all the tropes in police detective series and uses the Watson to explain the concept of the Watson with the following dialogue.
*** Winne, I don't understand.
*** Of course you don't, that's your function.
*** What do you mean?
*** This allows me to explicitly explain things.
* Similar to the ''{{Frasier}}'' example above, Robin was this in the first two or three seasons of ''Series/HowIMetYourMother'', asking questions about situations or conversations that relied on backstory from Ted, Marshall, and Lily's long, closely-shared history together so that the characters (or Future Ted) had an excuse to explain it to the viewer. It's implied Barney has had most of these things explained to him before 2005. By season 3-4, Robin (and the audience) had already gotten a huge amount of pre-series backstory and isn't much of a Watson anymore, and so the writers started to rely more on in-show established continuity to form the basis of these kinds of stories, usually heralded by Future Ted remarking "Kids, remember how I told you about that time..."
* Mike Rowe of the documentary series ''DirtyJobs'' is a professional Watson, learning the ropes of his latest dirty job from his bemused temporary co-workers.
** In fact, many presenter-led documentaries use this technique.
* An interesting variation happens on ''Series/{{Columbo}}'' where the Watson is played by the ''murderer of the week'' who tries to use this relationship with the eponymous detective to try and veer him off their scent. It never works. They always slip up somewhere, and Columbo picks up on the critical clue.
* ''TheInspectorLynleyMysteries'' has both the main characters do this! Frequently it's {{Deuteragonist}} DS Barbara Havers to her partner (the titular DI Thomas "Tommy" Lynley), but it's not uncommon for ''him'' to be ''her'' Watson as well.
* Carter fulfills this role in the first season of ''{{ER}}''. He's the the new medical student so the other doctors (mostly Benton) explain how things run at the hospital and many medical stuff too.
* Joan Watson of ''Series/{{Elementary}}'', naturally. Like her namesake, she is exceptionally bright in her own right; her main purpose for the audience is to ask the necessary questions to get inside Sherlock's head, since otherwise no one would have the slightest idea what's going on upstairs with him.
* Jesse takes this role in ''Series/BreakingBad'' whenever Walt has to explain the chemistry behind what he's doing.
* On ''Series/TheXFiles'', Scully plays Watson to Mulder's Sherlock, especially in the early seasons. The only time this switches is when Scully is performing an autopsy, though even then she's forced to try and decode Mulder's unusual thought process and the strange leaps of logic he's taking with the information she's in the process of giving him.
* ''Series/TwinPeaks'': Diane, a character who is never seen or heard. When recording his observations and thoughts on tape, Special Agent Cooper addresses her by name. She is most likely his secretary at FBI headquarters, although her identity is never actually stated.
[[/folder]]

[[folder:Theatre]]
* ''CyranoDeBergerac'':
** Le Bret. Half of his dialogue is asking Cyrano the same questions the audience must be asking (why in hell did you do something so jerkass/ stupid/ self-destructive) and letting [[JerkJustifications Cyrano explain what's going on]]. The other half of his dialogue is scolding Cyrano for being a jerkass.
--> '''Le Bret:''' But these strange ways, \\
Where will they lead you, at the end? Explain \\
Your system—come!
** Subverted by the Duenna. She asks Raguenau [[DrivenToSuicide why he intented to kill himself.]] After his response, [[JerkAss she changes the conversation]].
* Mary Lennox in the musical version of ''Literature/TheSecretGarden'' takes on this role temporarily when Mrs. Medlock introduces her to her new home, conveniently telling Mary all the backstory of the home and the family for the audience to hear.
* Little Sally from the musical ''{{Urinetown}}'' is a parody of this.
* What happens when two of the dullest Watsons ever are left to themselves and try to ask one another the questions? ''WaitingForGodot''. (Pozzo tries to be one too, but they're too incoherent to explain anything.)
[[/folder]]

[[folder:Video Games]]
* The various Snakes of the ''VideoGame/MetalGearSolid'' franchise seem to serve this role well, although the exact reason why is pretty [[PlayerCharacter obvious]]. The original idea behind the [[AndNowForSomeoneCompletelyDifferent protagonist switch]] was that Snake would have someone to be TheWatson ''for'' him instead of being TheWatson himself, letting him come across as more astute and mature. (HideoKojima even cited inspiration from ''SherlockHolmes'' and ''Series/DoctorWho'' for the idea.)
** And he happens to be the most (only?) reality-grounded character in ''VideoGame/SuperSmashBros Brawl'' to boot, making for some hilarious codec calls where he [[MetaGuy tries to come to grips with the weirdness of the game]].
* In ''VideoGame/FinalFantasyX'', the PlayerCharacter Tidus fakes amnesia so that he can play the Watson to the rest of the cast (he actually has a real reason for not knowing the the things he asks about, but it doesn't fly too well with the xenophobic people he hangs around with). Unfortunately in order to make sure that [[ViewersAreMorons every player]] is keeping up with the plot, Tidus finds himself ''constantly'' bugging people for exposition, to the point where his friends aren't sure if he's actually amnesiac or just an idiot. Fortunately for everyone, he gets better as the plot goes on.
** It gets to the point where Lulu starts explaining things before he even asks, leading him to comment that she's gotten so used to him asking questions that he barely needs to ask anymore.
** A quote from Lulu after one too many explanations : " Are you sure it's not your brain that's the problem?"
* WordOfGod has this as Dom's role in ''VideoGame/GearsOfWar'', to give the audience a voice without bringing players out of the experience as [[TheStoic Marcus.]]
* Leonard, the main character of ''VideoGame/WhiteKnightChronicles'' (as opposed to your avatar who represents you, but has little story relevance). The other characters start [[{{Lampshade}} Lampshading it]] early on, with a random chatter once the game proper kicks off involving two characters remarking on how bizarre it is that Leonard knows nothing about Bigelows -- who form the backbone of communication in TheVerse, with their flight and ability to transmit images and voice between a pair allowing them to act as the setting equivalent to e-mail.
* [[AmbiguousGender Lion Ushiromiya]] plays this role to the detective [[TheFettered Willard H. Wright]] in the seventh arc of ''VisualNovel/UminekoNoNakuKoroNi''. After a while they even start to refer to each other as "Watson" and "Holmes".
* In ''VideoGame/MassEffect1'', Liara takes this role. Due to Shepard having an entire library of Prothean data downloaded into their mind via one of their Beacons, this leaves Liara, as a Prothean expert, to try to delve inside the sheer masses of information present in Shepard's mind and attempt to understand what their visions actually mean.
** Shepard him/herself, particularly in the first game, to the point of making, "What can you tell me about [thing]?" a minor meme. Most of this dialogue is optional, but Shepard still serves the purpose of letting other characters speak at length about various things, even when there's really no clear reason why Shepard wouldn't already know what they tell him/her.
** James Vega, the only new (non-DLC) squadmate in ''VideoGame/MassEffect3'', is essentially this, serving as an outside observer of the merry gang and connections network that Shepard gathered in the previous games and easing in the introductions for new players.
* George tends to be this to Nico in ''BrokenSword''. George is a clever adventurer and problem-slover, but he knows virtually nothing about his environment (Paris). Nico's main contribution to the plot is reminding George being a foreigner allows Nico to be MrExposition for the player without seeming like she's repeating pedantic information.
* Various [=NPCs=] and companions in the ''Franchise/DragonAge'' franchise fill this role as needed to either the Warden or Hawke. The dialogue wheels for both {{player character}}s allow the player to ask questions, or not, about the background of Thedas and the history of the Grey Wardens and whatever else they don't already know, depending on how many times they've played the game.
* You, as the [[NoNameGiven unnamed protagonist]], fill this role to Creator/EdgarAllanPoe's C. Auguste Dupin in the ''VideoGame/DarkTales'' PC games. Dupin is, in-universe, the master detective and hero of the games, but as the player character, you're the one who actually does all the work; Dupin mostly functions as MrExposition.
* Simultaneously suffering from [[AmnesiacHero amnesia]] and having lived most of his life in his family's manor with little to no exposure to the outside world, Luke from ''VideoGame/TalesOfTheAbyss'' makes for a perfect Watson.
* The Avatar in ''VideoGame/UltimaIX'' is a prime example of this trope done poorly. Having not only been to Britannia multiple times, but helped shape much of its history, suddenly he's given the option to ask about even the most basic things even though [[AsYouKnow he should be familiar with them already.]]
--> '''Avatar''': [[MemeticMutation What's a paladin?]]
[[/folder]]

[[folder:Web Comics]]
* In the webcomic ''{{Erfworld}}'', the character Parson acts as both TheWatson inside the narrative and MrExposition through a diary.
* ''Webcomic/TheOrderOfTheStick'' has a procession of short-lived hobgoblin cleric assistants that can cast ''Transmute Redcloak to MrExposition'' at will.
** WordOfGod says that this was always Jirix; he just kept getting resurrected off-screen.
** Qarr the imp has become TheWatson to the Inter-Fiend Cooperation Commission.
* ''MSFHigh'': This is Donovan's role. Fortunately, he is also TheHero in training.
* As pointed out in ''[[http://www.harkavagrant.com/index.php?id=210 Hark, a Vagrant!]]'', Dr Watson does seem to get unfairly [[{{Flanderization}} flanderized]] in most portrayals outside of the original Sherlock Holmes novels.
* In ''TemplarArizona'', Ben is the Watson most of the time, because the work is partly about this weird town, but there are aspects of the alternate-historical universe familiar to Ben but not us; for this, there is a new Watson ([[http://templaraz.com/?p=1611 Mesmer]]) with an even more sheltered upbringing.
[[/folder]]

[[folder:Web Original]]
* Pohatu rapidly became this in the ''Franchise/{{Bionicle}}'' serial ''The Powers That Be'', as he was trying to solve a murder mystery with the increasingly Holmsian [[TheStoic Kopaka]]. Given his RunningGag of asking for clarification every time he hears a new name, this makes sense.
* This is a big part of Sparadrap's role in ''Franchise/{{Noob}}'', in addition to ForgetfulJones tendencies that allow him to ask the same question at different points in the story.
* Texas of ''WebVideo/TheOtherSide'' takes this to the extreme. Apart from one scene, every line he ever speaks is in the form of a question.
[[/folder]]

[[folder:Western Animation]]
* The entire ''premise'' of ''WesternAnimation/{{Futurama}}'' is Fry ending up in situations that need to be explained to him because of the thousand years that went by without him. Holy crap, there's a theme park on the moon!? Hilariously, on multiple occasions a new character will be thawed out (Fry's ex-girlfriend and That Guy from TheEighties) and become ''Fry's'' Watson, which not only demonstrates his [[CharacterDevelopment considerable ability to acclimatise]] (read: there's still TV and beer, so he's just dandy), but also gives him a chance to show how little he retains of what he's learned.
** Originally, the creators envision the show being about Fry's difficulties adapting to the future. They were surprised at how quickly he adapted, so they instead started to focus on Fry being stupid instead. Watching an episode from the first season then one from the most recent season, there is a clear difference in both the plots and Fry's attitudes.
* Gus Griswald from ''WesternAnimation/{{Recess}}''.
* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode "[=MMMystery=] on the Friendship Express", Pinkie Pie tries to investigate who sabotaged a cake she was guarding, and forces Twilight Sparkle (normally TheSmartGuy) into the role of "my lowly assistant who asks silly questions with obvious answers." When Pinkie's methods (which largely consist of making wild, baseless accusations) prove ineffective, Twilight manages to get Pinkie to switch roles. Once Pinkie starts to understand the importance of getting all the facts, they switch again so she can solve the mystery of who ate all the other desserts on the train.
