Identical Twin Mistake - TV Tropes

  • ️Thu Jun 21 2018

Identical Twin Mistake (trope)

In Real Life, identical twins are still often different enough to be distinguishable. In Fictionland, this isn't always the case. Many times a twin will be mistaken for their sibling, whether or not they realistically would be.

This may happen intentionally, as part of a Fake Twin Gambit, a Twin Switch, or if a character is Impersonating the Evil Twin, but just as often it's a complete accident, with hilarity following. However, this can also be used for drama, if the mistake leads to an actual problem rather than a gag; this route is common when one twin is a criminal. If the twins are babies, expect this to happen often. This trope is also an obvious common outcome of Twin Tests as the siblings explicitly ask others to point out who is who.

Contrast Identical Twin ID Tag, where the twins make a conscious effort to avert this trope. Compare Ambiguous Clone Ending, where the characters and the audience is left unsure who is the clone. Also compare Identical Stranger and Inexplicably Identical Individuals, who may also be confused for each other. Supertrope to Twin Switch and Impersonating the Evil Twin, as those tropes rely on this confusion to work.

Examples:

open/close all folders 

Anime & Manga 

  • While in the anime proper Kouji and Kouichi from Digimon Frontier are easily identified by their different hairstyles, a later radio drama reveals that two years later they look enough alike that people in the middle school they now attend together mistake them for one another, to the point a girl mistakenly confesses her love for one of the twins when she meant to confess to the other.
  • Ouran High School Host Club: The only person who can tell the Hitachiin twins from sight alone is Haruhi. Everyone else struggles, not helped by the twins' tendency to switch their identities, mostly for laughs. After his Character Development, however, Hikaru decides to dye his hair black to differentiate himself from Kaoru. The anime makes this a case of Alleged Lookalikes, because even though the twins have the same appearance, their voices are completely different (Kaoru has a much softer voice than Hikaru).
  • In The Quintessential Quintuplets, when Fuutarou and the Nakanos all end up in class 3-1 together, it's shown in chapter 70 that their classmates are even worse at telling the quintuplets apart than Fuutarou is. This leads to situations like a pair of girls trying to bring one of the sisters to a teacher and grabbing the wrong one by mistake (three times in a row!), or other students asking Fuutarou to pass a message/item to a quint that's standing right next to him.
  • The Duke of Death and His Black Maid: When they first meet Daleth, both Nico and Ichi mistake her for Sade. Since both of them had played a hand in her death, they conclude she must have returned Back From The Death somehow. Daleth, for her part, plays along for a bit in order to gain information, but desists when she overhears their battle might threaten Walter.
  • Zekkyou Gakkyuu: Nana and Nono from The Story About Twins get mistaken by sight alone despite them having different haircolors.

Asian Animation 

  • Adit Sopo Jarwo: "Saudara Berkunjung Semua Tersanjung" has Jarwis, Jarwo's much nicer twin, comes to the suburb and gets mistaken for Jarwo. Those who sees Jarwis is confused at seeing Jarwo being generous and polite until it gets cleared up at the end of the episode.

Comic Books 

  • The Baby-Sitters Club: Marilyn and Carolyn Arnold get mixed up by everyone, because their mother dresses them in matching outfits; kids at school call them Marilyn-or-Carolyn, not bothering to tell them apart and treat them like one person. This upsets them greatly.
  • One instance of Green Arrow meeting Black Canary has him saying that he's had a huge crush her for years. Black Canary is offended because he's talking about her mother.
  • Gravity Falls: Lost Legends: When Pacifica first saw Ford, she assumed he was Stanley, though she notices that he looks very different. The comic ends before we see if anyone explained the truth to her.
  • Supergirl:
    • In Starfire's Revenge, Supergirl mistakes Rodney Marlowe for his twin brother Derek. Much to her confusion because Derek was reported dead.
    • In Supergirl Special, a security guard mistakes Power Girl for her alternate self Supergirl when he is rescued by the former.
  • Wonder Woman: The Heyday triplets (three of the Holliday Girls) are identical and are commonly mistaken for each other even when they're not pulling a Twin Switch, which leads to them being ordered to wear name tags. They generally avoid the name tags, which comes in handy when their vile elder brother abducts them to make them sign over their inheritances. It doesn't work because he can't tell which one should be signing which name.

Fan Works 

  • Played for Drama in the Pokémon fanfic Airplane Mode. After going missing for years, Subway Boss Ingo returns to Gear Station, where he is mistaken for his identical twin brother, the other Subway Boss Emmet. Specifically, a senior Depot Agent thinks that Emmet pretends to be Ingo to cope with his death, and begs him to take the week off. Ingo proves that he's not Emmet by having the agent call his phone.
  • The Bridge: The Sirens and Dark Hunters get a bone to pick with Twilight Sparkle after she allies with the dark magic source the Hunters are going after along with stealing Sonata Dusk's necklace, leaving her scarred and sickly. This causes Monster X to threaten the resident Rainbow Dash, knowing it would draw the hiding Twilight out. So when Princess Twilight Sparkle arrives after being summoned by Sunset Shimmer, it's not even two hours into her arrival when Monster X and Gigan ambush the party and kidnap her to demand information and the return of the necklace. Problem? She has no idea what they are talking about. It's only after discussion they realize it was the human world's resident Twilight Sparkle that was responsible.
  • A Certain Droll Hivemind: Since the Sisters normally wear the Tokiwadai Middle School uniform, when Touma sees a girl who looks like Misaka Mikoto wearing different clothes, he assumes it's Mikoto. It's actually Misaka-11111, who got dragged out clothes shopping because her flatmates were annoyed at her wearing the uniform of a school she didn't even go to.

    "'I am not Misaka Mikoto. I am Misaka-11111,' Misaka repeats," I tell him again.
    "But you're wearing different clothes," he protests. He does not appear to understand that we have the capacity to wear clothes that are not Misaka Mikoto's school uniform. We are not sure if Kamijou Touma has ever approached Misaka Mikoto when she is on her way to school under the impression that she is one of us. Statistically, if you see someone who looks like Misaka Mikoto wearing the Tokiwadai uniform, you should assume that they are a member of the Network. The chance that they are the original can be discounted as statistical noise.
    We suspect he would probably realise his mistake quite quickly. The original would probably not appreciate it.

  • Cheater, Cheater: It's mentioned that George's 20th and 21st exes, a pair of twins, broke up with him because George thought he was dating just one guy.
  • Features in the Modern AU How to Train Your Dragon fic Confusion, as Astrid and her OC twin sister Lillian start dating Hiccup while involved with each other; initially all three were unaware that the sisters were dating the same person while Hiccup assumed that he was dating one girl who acted differently in clubs and on campus, only realising that there were two of them when he was invited to their apartment. After they settle into a triad relationship, as part of their efforts to stop their mother finding out that Hiccup is dating both girls, at one point Lillian pretends to be Astrid when their mother comes to the sisters' flat while Astrid is out (their parents having been told Hiccup is 'just' Astrid's boyfriend).
  • Twinning With a Twist: At one point, Topher mistakes Sammy for Amy and flirts with her, which motivates Sammy's Expository Hairstyle Change. In a lesser example, Max does this after Sammy arrives at Playa des Losers, just before the finale.

Film — Animated 

  • Rover Dangerfield: Coonhound twin brothers Rem and Clem look the same. In their last scene, Rover gets them mixed up and they argue amongst themselves over which one is which.

Film — Live-Action 

  • Assassination: Kang In-guk, an evil member of Les Collaborateurs in league with the Japanese, kills his long-lost daughter Ok-yun, because she is a member of La Résistance fighting against the Japanese. Except, he actually killed his other daughter, Machiko, the one who wasn't separated at birth and wasn't fighting for Korea or plotting against him. Ok-yun proceeds to assume her dead sister's identity and infiltrate her father's household so she can get another shot at murdering him.
  • In Double Impact Jean Claude van Damme plays twins. They are at first mistaken for each other, but they have very different personalities and are soon told apart.
  • The twins from the Firefly movie Serenity try to invoke this by pulling the Twin Switch on people for fun. They're frustrated that Mal can always tell which is which.

    Mal: Mingo. [Nods to Mingo] Fanty. [Nods to Fanty]
    Mingo: He's Ming–
    Mal: He's Fanty, you're Mingo.
    Mingo: [Stares at Mal for a moment before reluctantly smiling] How is it you always know?
    Mal: Fanty's prettier.
    Fanty: (smirks at Mingo)

  • Twin Dragons stars Jackie Chan as twins, Separated at Birth. One is raised in a wealthy family and grows up as a music conductor, the other is adopted by a homeless woman and becomes an asskicking badass, typical Jackie Chan style. For the climax, guess which Jackie gets captured by baddies and which gets mistaken as a musician and forced to perform onstage, in front of a thousand audiences.
  • Twin Sisters of Kyoto: Hideo meets Naeko when he accidentally gives her the obi (a kimono's sash) that he weaved for Chieko. (Hideo does not know about Naeko because Naeko and Chieko were Separated at Birth.)

Literature 

  • Fox Demon Cultivation Manual: The real Feng Zhuojun died years ago. The man Jiang Liang thought was Feng Zhuojun, the one who got married and apparently betrayed Jiang Liang, was actually his twin brother.
  • In The Chronicles of Narnia novel The Horse and His Boy, protagonist Shasta is suddenly grabbed off the street by the Narnian royalty, who think that he's Prince Corin of Archenland. Shasta stays with them and hears some plot-significant information before being left alone...at which point the identical Prince Corin climbs in through the window, having sneaked out to explore the city. By this point we've established that Shasta knows nothing about his birth family, so you can probably figure out the twist.
  • This sometimes happens with Fred and George Weasley from Harry Potter, even by their own mother. Often it's because the twins themselves pretend to be each other just to troll others.
  • In Flawed, this is downplayed, occurring between sisters that look alike, but are months apart in age. Celestine, who was branded as "flawed", still has to go to her high school while marked, forced to always wear a red arm band. Her similar-looking older sister Juniper is one day photographed from behind, mistaken for Celestine, and since Juniper doesn't have a band, everyone thinks Celestine broke the rules. This causes Celestine to be expelled from school.
  • In The Folk of the Air faeries repeatedly have issues telling Jude and Taryn apart. Locke, having wooed both of them, is so bad at differentiating the two that when Jude attempt to threaten him and tell him to treat Taryn well, he initially assumes Taryn has randomly become violent with him. Cardan even goes so far as to suggest that Locke couldn't tell which was which when he first tried to court Taryn, and it was chance that Taryn ended up being the first twin he approached. Taryn also takes advantage of how few people can tell them apart (as well as the fae rarely taking into consideration that humans are capable of lying) to claim to be Jude in order to take advantage of her status.
  • Played for Drama in Simon and Ethan's case in It Had to Be You. In their early 20s, they looked so much alike people often mistook one twin for the other from a distance and they wore matching outfits on the night of their graduation party, making it even harder to tell them apart. Consequently, none of the attendees of the party can be certain which twin was where at any given time or if either of them left at any point, meaning neither of them have much of an alibi for their parents' murders. The police even theorised the brothers intentionally invoked this to create confusion and get away with their crimes, something they both fervently deny.
  • The Twin Switch in Lottie and Lisa is so successful that the girls are only found out by complete coincidence. They look exactly alike except for their hairstyles which are easily disguised. However, they are also Polar Opposite Twins and have to work hard to maintain their charade, which causes especially Lotte a lot of stress and anxiety. They would probably have been found out due to their different personalities and lack of knowledge about each others' lives had it not been for the fact of the parents being distracted by their own problems. Their looks, however, are so identical that they themselves cannot distinguish between each other in a photo.
  • Our Man Weston. A constant gripe of Tom Weston is that he keeps taking the blame for the antics of his twin brother Sidney.
  • In The Rolling Stones (1952) Castor and Pollux, 'the Unheavenly Twins', use this to trick their teachers, with one twin taking two identical classes.
  • In the Sophie books, not only do the twins Matthew and Mark pretend to be each other sometimes, but they often get mistaken for each other.
  • In the first book of Sweet Valley High, bad girl Jess goes to a dive bar and gets involved in a fight. The cops mistake her for her more innocent twin sister, Liz, causing Liz to be the butt of rumors at school. This actually happens repeatedly throughout the series, to dangerous levels—Jessica's stalker kidnaps Elizabeth by mistake, while a guy stalking Elizabeth because she witnessed him committing a crime abducts Jessica.
  • In a Sweet Dreams book, a girl runs into the guy she met a few days ago and happily chats with him, not understanding why he seems weirded out by her behavior. When she runs into him again and blasts him for his rudeness, he realizes that it's his twin she was talking to and that his attitude was because he thought she was coming on too strong (oddly, at no time did it occur to him that she'd simply mistaken him for his brother).
  • Gareth and Gaheris in Sword of the Rightful King are physically identical and can only be differentiated by behavioural quirks. Their older brother Gawaine is one of the few people who can reliably tell who's who.

Live-Action TV 

  • The Acolyte: Osha spends the first episode being suspected of a murder that her sister Mae committed; it's a Justified Trope, as Mae was believed dead sixteen years ago, and the Jedi had no reason to suspect she had miraculously survived. It's also unintentional on Mae's part, as she thought Osha was dead, and didn't expect her to be accused of her crimes.
  • All My Children's Adam Chandler would often deliberately invoke this, pretending to be his good twin Stuart, usually to pull off some nefarious act, occasionally dragging Stuart into it against his will.
  • Arrested Development:
    • Happens repeatedly in the episode "The One Where Michael Leaves" with the police mistaking Oscar for his fugitive twin brother George. Except the last time when George deliberately disguises himself as Oscar to invoke this.
    • Invoked again in "Righteous Brothers" when George gets Oscar sent to jail in his place. The following episode reveals that "You've got the wrong twin" is a very common retort to the police.
  • The Barrier: Hugo is recently widowed from Sara, a woman who had an identical twin sister named Julia. At some point in the series, Hugo and Julia walk by a closed-down night club style bar that they both recognize. Hugo tells Julia the bar is the place where he first saw Sara and fell in love with her, but didn't manage to approach her or get noticed by her, resulting in him first asking Sara out after running into her again somewhere else. In Hugo's flash-back to when he first saw Sara, a pendant necklace of which the twins owned identical versions that differed only in color is hidden under Sara's top and Sara is wearing braids, which are favored by Julia. Julia is also surprised that Sara would ever go to that bar, as they were Tomboy and Girly Girl twins to an extent and Sara was the girly girl. Guess who Hugo actually saw in the bar that evening.
  • El Chapulín Colorado has an episode titled "Cuando los gemelos no son buenos cuates" note . A couple of twin brothers are rehearsing for their show in a dancing theatre, and the girlfriend of one of them starts off by mistaking his brother for him. Then a new janitor comes and, since he's not familiar with the performers, doesn't know they're twins and thinks it's a single guy trying to mess with him, leading to a bunch of hilarious arguments. Only at the end do the twins appear together to clear the misunderstanding, and the brother who has a girlfriend ends up mistaking her own twin sister for her.
  • The title character of Columbo once used this to trick a murderer into incriminating himself. The murderer had almost run over a blind man while fleeing from the scene of the crime. Later, Columbo brought in what appeared to be the same blind man to identify the murderer. The killer protested that the man was blind. Then Columbo asked why the killer would think that, since when the man he had brought in wasn't wearing dark glasses or carrying a white cane. The killer claimed that as a trained physician he could spot subtle clues. Then Columbo had the "witness" read from a newspaper. The "witness" was the blind man's identical twin brother, and by claiming the witness was blind the killer showed that he had mistaken the man for the blind man who was almost run over.
  • The final moment of one episode of Criminal Minds reveals that they arrested the wrong person, with the closing quote being "There are only two things in life that are ever unexpected. Twins." The next episode clarifies that the unsub and his brother were separated as toddlers and even the unsub himself didn't know he had a twin brother. The arrested twin, Jesse, had insinuated himself into the investigation as part of a plan to make contact with the guilty twin, Wallace (and eventually Kill and Replace him). After the brothers have met, a coworker of Jesse sees Wallace leaving Jesse's house and assumes it's Jesse. He's too freaked out to correct her, so he just runs away.
  • One episode of CSI deals with the Victim of the Week being a soccer mom that was shot in a parking lot, and the investigation eventually leading to a house where the woman's identical twin has apparently hanged herself. Turns out that the women were long-lost twins and the one who apparently committed suicide had become a newspaper editor and was about to rat out a photographer that had photoshopped pictures of the Second Gulf War to "make them more representative of War Is Hell", winning a prize for that. He had seduced her, drugged her and hung her, and seeing her twin made him believe that she had somehow survived that and shot the twin just to make sure.
  • Dark Angel: Most or all of the X5-series Super Soldiers were created as pairs of identical twins, such as the series's heroine Max and her twin Sam (both Jessica Alba). In the case of Alec and his twin Ben (both Jensen Ackles), this proved problematic because Ben was a Serial Killer, and although Ben died in the first-season episode "Pollo Loco", Alec got arrested for one of his murders in the second-season episode "Hello, Goodbye" (the victim's wife identified him in a lineup and his DNA was a 100% match for Ben's left at the scene). Max had to have a fake birth certificate made showing Alec had a twin (genetically engineered creations of The Conspiracy don't come with birth certificates, naturally) and a fake passport showing he wasn't in the country when the murder happened in order to clear him.
  • On Deception (2018) identical twins Cameron and Johnny Black have been using the Twin Switch as part of a magical act for most of their lives. Very few people know that Johnny exists which allows them to do spectacular teleportation tricks eg. Cameron disappears in an explosion on stage in Las Vegas and Johnny then appears on a similar stage in Times Square in New York City. In the series premiere Cameron is arrested for a crime committed in New York City and realizes that the police have mistaken him for Johnny. Once the twins' secret is revealed to the world, Johnny is sent to prison and Cameron tries to prove that he was framed. Once Cameron confronts the Mystery Woman behind the frameup ,she realizes that she framed the wrong brother. She once met Johnny but mistook him for Cameron and when she wanted to recruit him for her scheme, she framed the other twin to get him out of the way. She is quite annoyed when she realizes that she got the wrong brother sent to jail.
  • Friends: As part of the shared universe with Mad About You, Lisa Kudrow plays both Phoebe and her twin sister, Ursula, who happens to be a character in the other show. This is joked about when the cast of Mad About You show up at Central Perk, and thinking Phoebe is actually Ursula, assume she's a waitress at the cafe (just as Ursula is a waitress at their local restaurant) and tell her their orders. Phoebe, naturally, is confused by this.
  • When General Hospital's Kevin Collins came to town, he had to contend with a lot of people mistaking him for his evil twin brother, the Psycho Psychiatrist and Serial Killer Ryan Chamberlain—his first appearance was being punched out by the boyfriend of the woman Ryan stalked and terrorized for a year prior. Not until it was confirmed that Ryan was still in prison did they believe he wasn't him.
  • House of Anubis: When Patricia's polar opposite twin Piper arrives at the house, this trope is in full force. Apart from their Twin Switch, Piper is mistaken for Patricia multiple times. This leads to Eddie kissing her, Alfie thinking his crush on Piper is a crush on Patricia, and the Sibunas thanking "Patricia" for getting rid of the stolen oxbow before the teachers checked her bag. Strangely, they did have an Identical Twin ID Tag with their necklaces. After Piper gives Patricia hers before leaving, Eddie then mistakes Patricia for Piper.
  • House of the Dragon: Ser Arryk Cargyll infiltrates Dragonstone to assassinate Rhaenyra Targaryen, only to be caught in the ruse at the last minute and confronted by his identical twin brother Erryk. Rhaenyra and the other guards can't tell them apart as they fight.
  • iCarly: In the episode "iTwins" where Sam's polar opposite twin Melanie is introduced, Freddie spends the entire episode thinking that Melanie doesn't exist, and is just Sam screwing with him. As the two are never seen together until the very end, the episode is set up so that the viewers are just as uncertain as Freddie.
  • A particularly heartbreaking version forms the basis of an episode of Law & Order: Special Victims Unit. A woman who had an identical twin threatened to report a crime syndicate to the cops because they were holding another sister hostage. A member of the syndicate went to her apartment to kill her, on the same night that it just so happened the other twin had come by to look for her sister. When the assassin found her there, he mistook her for his target and killed her.
  • An episode of Nash Bridges involves a pair of twin brothers, one of whom is a city official while the other is a criminal. At one point, Bettina arrests the criminal, but lets him go when he claims to be the city official. Soon after, Bettina encounters the official and arrests him despite his protests. Being an idiot, Bettina doesn't ask for proof of identity either time.
  • In Murdoch Mysteries, this is a long-running subplot in Season 14: Having been kidnapped by the Axe-Crazy Stalker with a Crush Amelia, Crabtree is horrified when he thinks he sees the same woman working as his girlfriend's secretary under an assumed name. She explains that she's Amelia's twin sister Dorothy, but given how good Amelia was at creating false narratives that she would believe herself, Crabtree is unconvinced. It eventualy turns out that she's telling the truth ... but she and Amelia are working together.
  • Sesame Street: Played with. Chip and Dip are brothers, and are probably from the same litter since they once mentioned learning to talk around the same time, though it's unknown if they are twins or if there were more of them. Nevertheless, when Oscar firsts meets them, he thinks they're both the same cat popping up.
  • Happens several times over the course of Sister, Sister, especially in the earlier seasons. For example, in the first episode, Separated at Birth twins Tia and Tamara coincidentally meet at the same store. One is looking for a sweater and the other is looking for a sweatshirt. They take turns asking the same sales clerk, who doesn't realize there are two of them and slowly goes crazy with them for constantly "changing their minds." Considering they didn't even know they were twins yet, a complete stranger couldn't be expected to know either.
  • The Sooty Show: When Sweep's twin brother Swoop visits in one episode, Soo and Matthew initially mistake him for Sweep.
  • The Suite Life of Zack & Cody: Downplayed. For the most part, the twins manage to avoid this trope, with the exception of three episodes:
    • "Poor Little Rich Girl" has them doubt their identities when they see a video of their mother getting them confused when they were newborn babies.
    • "Rumors" has Moseby banning both of them from the game room after Zack uses the Coin-on-a-String Trick. As a result, Cody tries to dye his hair auburn as an Identical Twin ID Tag, but it turns blood-red instead, and he has to use charades to help Zack pose as him during an interview.
    • "Commercial Breaks" has all the Tipton employees auditioning for a commercial. Cody's audition is turned down, and one employee audition later, Zack tries to audition, but the director mistakes him for Cody trying to cheat. He doesn't learn the Cassandra Truth until the twins try to pull off a Totem Pole Trench.
  • An Unsolved Mysteries segment about a man searching for his long-lost twin brother kicked off with one of his friends confronting him about how rude he'd been when they ran into each other the other day—he blew off his efforts at conversation and claimed to not know him. The man was completely bewildered, as he'd been out of town, leaving his friend equally confused. Upon digging further into his past, he learned that he and his twin had been adopted by separate families.

Radio 

  • In the Chilean radio program El Chacotero Sentimentalnote , there was a case of a guy who had a girlfriend and she has a twin sister. He tells about his relationship with his girlfriend but then sometimes he noticed his girl acted very different, to noticed time later she made Twin Switch with her sister, so he basically was dating both sisters without noticing it.

Video Games 

  • A meta-example occured with Animal Crossing: New Horizons with the dodo twins Wilbur and Orville, the only physical difference between them being that Wilbur wears Cool Shades. While they aren't mistaken for each other in-game, Nintendo themselves made this mistake in the initial release of the 2.0 update. Inviting characters to the photo studio unlocks a poster of them, but in the dodos' case, inviting one twin would unlock the poster of the other. This was confirmed to have been an actual mistake and not a tongue-in-cheek joke when it was fixed in the 2.02 patch.
  • In the second Boktai game, during the mission in the Remains, Django gets mistaken by Kid for his twin brother Sabata, who saved Kid earlier in the story. (How this could happen is confusing, considering that both twins have distinguishable hairstyles and hair and eye color).
  • Final Fantasy XIV has the Half-Identical Twins Alphinaud and Alisaie Leveilleur who do look very alike despite being the opposite gender and people often confuse them.
    • Whilst they go through a Twin Desynch over the course of the second expansion (Stormblood) which prevents this for most people - this doesn't stop Estinen, who met Alphinaud alone in the first expansion (Heavensward) from mistaking them when he meets Alisaie for the first time between the fourth (Shadowbringers) and fifth (Endwalker) expansions. He was trying to complement Alphinaud looking more manly than he used too, so the tomboyish but still proudly female Alisaie does not take this well.

      Alisaie Leveilleur: I... am not... ALPHINAUD!

  • Before the events of Fire Emblem: The Binding Blade, Raigh stole one of Hugh's spellbooks. Before the beginning of Hugh and Lugh's support, Hugh mistook Lugh for Raigh and grabbed him by the collar: to his credit, Hugh realizes his mistake and starts said conversation by apologizing to Lugh. When Lugh apologizes for Raigh's general bad behavior, Hugh waves it away and insists that he was the one at fault for being so violent towards a kid.
  • Her Story suggests that the trigger for the murder was Hannah posing as Eve and Simon falling for the deception, giving her another "unique" mirror to show his love. At least that's her story.
  • A sidequest in Octopath Traveler II involves a strange blonde-haired man who waits at a table outside the tavern in Canalbrine, who is noted by a local that he waits all day outside looking for someone before giving up and leaving, only to show up again and sit in the same spot while waiting all night before the cycle continues in the morning. If you look closely, they're actually two different people with differing hair lengths and unmatching outfits. If you take one of them with you and cycle the day so they can meet the other guy, it turns out they're twin brothers who arranged to meet each other, only for the letter one brother sent got dirtied and the other assumed they were supposed to meet during the day when it was actually at night, while both somehow kept missing each other.

    • "My sister slept with someone's husband and almost got murdered": A woman broke into Honami's house shouting at her with murderous intentions as she mistook her for her twin sister, Minami, who stole her husband, named Hiroki, from her. When Honami comes over to clarify things, the woman, named Youko Sato, apologizes for the mistake and teams up with her to catch Minami in the act.
    • 'On our anniversary at a restaurant, a little girl ran up to me and yelled "daddy"': This almost ruined Kota and Charako's relationship when a little girl named Ayaka entered the restaurant where they held their first wedding anniversary and called him "daddy". Kota reveals that he had a twin brother who separated from him after their parents divorced. When they took Ayaka to the police to find her real parents, a man from the orphanage she was in revealed that Kota's twin brother and his wife died in a car crash, with Ayaka left as the only survivor.
  • SparkTales: In "Sister's Fiancé Drama: Shocking Wedding Day!", Lisa's younger sister Briony gloats about having stolen her fiancé, Noah, with her parents backing her up. When Lisa talked it out with Noah, it's later revealed at Briony's wedding day that the "Noah" she stole was actually his debt-ridden twin brother Greyson. Moreover, it turns out Greyson tricked Briony and her parents into co-signing his debts and could have gotten away with running off had Mia not caught and dragged him to the wedding venue.

Webcomics 

  • Cirque Royale:
  • In The Inexplicable Adventures of Bob!, when Fructose Riboflavin first encounters Galatea, he assumes she's her identical sister Molly, and takes great offense that she doesn't recognize him. In turn, Galatea is irritated when she realizes he's mistaken her for Molly.
  • Kevin & Kell: Despite being cousins rather than twins, Shelia and Kell look alike, and a reoccurring accusation is that when Shelia is trying to be responsible or relate to her stepdaughter Leona, she's actually Kell covering for her, which does annoy her. In an attempt to avert this as well, Frank's pictures of him with Shelia also include Kell (who's his boss), so people don't make awkward assumptions about Frank and Kell's relationship.
  • A fraternal twin example occurs in Welcome to Room #305. Rumors spread about the campus that Yoongsung is a crossdresser. It turns out people were seeing his Half Identical Twin sister Yoona.

Western Animation 

  • Carl the Collector: Throughout "The Fake Mustache Collection," Nico is confused for Arugula, which frustrates her.

  • Gravity Falls: After his fraternal twin brother's disappearance, Stan went shopping in town and was mistaken for him (the brothers are noticeably different-looking, but the townsfolk weren't very familiar with either). He went along with it, inspiring him to assume his brother's life entirely.
  • The Garfield Show: A running gag has people not being able to tell Jon Arbuckle's twin nieces/cousins once removed Drusilla and Minerva apart. Heck, sometimes the twins get themselves mixed up.

  • The Loud House:
    • Played with in "Training Day", when Lana initially thinks Snazzy the rabbit is Stella's rabbit Jazzy. They turn out to be brothers from the same litter, though it's unknown if there were any others in the litter.
    • In "Fam Scam", when Cricket sees her classmate Lola's twin sister Lana for the first time, she believes that Lola changed her clothes.
    • In "Double Trouble", when the Loud twins meet Scoots's twin sister Mopes (so-called because she rides a moped), they think she is Scoots in disguise.
  • Razzberry Jazzberry Jam: At the beginning of “A Bonnie Tale”, Buddy mistakes Bonita for her twin brother Woody (who the Jazzberries had been expecting, but who had to send Bonita in his stead due to being sick).
  • Rugrats: Happens often with Phil and Lil. In "Twins' Pique" in order to differentiate themselves, Phil and Lil change their personalities to be more like Chuckie and Angelica respectively.
