Time-Travelers Are Spies

Go To

Guard: Commander, I have found these spies!
Doctor: We're not spies, honest. Didn't you see the last episode? We always coincidentally bungle into battlezones and get suspected of spying.
Doctor Who and the Revenge of the Unrealistatrons

...or at least they're likely to be mistaken for them whenever the era they travel to is familiar with the concept.

Think about it. If you're from a different time, then you:

  • Possess a bunch of knowledge that most people wouldn't have, some of which may very well be classified in the time you've arrived in.
  • Lack a bunch of knowledge about pop culture and current events that most people would have.
  • Probably have an accent that sounds slightly off.
  • Can't convincingly account for your past, because you literally don't have one in that timeline.
  • Have goals which probably look incomprehensible to other people, and therefore are likely to be taken as cover for something more sinister.

All of these will make you appear to be a spy to anyone who takes enough of an interest in you to notice.

Compare Fish out of Temporal Water, the root cause of this trope.

    Comic Books 
  • In an Archie Comics story, Jughead accidentally travels back in time to The American Civil War. He is mistaken for a Confederate spy with inferences made about the S on his shirt standing for "Spy" or "South".
  • Mortimer experiences this twice in the Blake and Mortimer album The Time Trap, the first when he automatically says he's English... in medieval France. In the second, he's flung into the dystopian future and is found by rebels.
  • This happens to Jimmy Olsen in a Silver Age story when he gets transported back to World War II and has to pose as a Nazi.
  • The EC Comics story "...For Us the Living" (Weird Fantasy #20) begins with an atomic scientist being arrested as a spy for a foreign power. The scientist admits his identifying documents are all forged because he came from an alternate time-branch in which Abraham Lincoln escaped assassination and brought peace to the world.

    Films Live-Action 
  • In Hot Tub Time Machine, Blaine and the ski patrol, all of whom are '80s Jerk Jocks drunk on Reagan-era Patriotic Fervor, mistake the main characters for Soviet spies after finding their cell phones and MP3 players (which they think are spy gadgets), and their can of Chernobyl energy drink with its Cyrillic lettering (which they think is a bomb). The protagonists later use this misconception to escape, spewing Russian-sounding gibberish and threatening to blow up the ski lodge if the ski patrol doesn't let them go.
  • In Safety Not Guaranteed, this happens for a different reason: Kennetch is chased because he breaks into nuclear facilities, for the purpose of getting something for his time machine.
  • Chekov and Uhura in Star Trek IV: The Voyage Home, in the famous "Noo-klee-ar wessels" sequence. Somehow they don't realize that, if you want to get aboard an American aircraft carrier in 1986, the guy with the prominent Russian accent probably shouldn't be your spokesperson. This doesn't cause them any problems in the end except for a bunch of strange looks, but when the inevitable transporter malfunction strands Chekov next to the reactor of aforementioned nuclear wessel he is assumed to be a Russian spy. His recitation of Name, (Starfleet) Rank, and Number do nothing to dispel this. One of his interrogators does express some doubts, noting that while Chekov obviously is a Russkie, he's also "a retard or something" because of Chekov's farfetched claims and Literal Mindedness.
  • Played with in The Film of the Book Timeline, where a group of 1999 History students travel to The Hundred Years War France and are captured by English soldiers. A Blood Knight singles out the only French student, who the rest insist is their interpreter in order to protect him (the group is posing as English pilgrims). Claiming that he is going to test if this is true, the knight orders the student to translate aloud a series of sentences that the knight says in French, into English; if the student refuses, the knight warns, he will be proven to be a spy and executed immediately. The last sentence the knight says is I am a spy. When the student painfully complies, the other English soldiers take it as a valid confession and kill him. This is then subverted when it is discovered that the knight is a time traveler himself and he knew from the beginning who the "pilgrims" were. It doesn't help that one of them is Scottish (played by Gerard Butler), and England was at the time also at war with the Scots. The Big Bad assumes that the Scots must be trying to ally with the French.

  • Pops up a few times in the Time Machine gamebook series, such as being taken for a Mexican spy during the Mexican-American war.

  • Isaac Asimov's Pebble in the Sky: Schwartz, who has inadvertently travelled to the far future, is assumed, by Secretary Balkis and agent Natter of the Society of Ancients, to be a spy from the Galactic Empire. Therefore, Natter is assigned to keep an eye on him.
  • In Driftless Wormhole, Mateo, an accidental time traveler, gets picked up for spying before he can even find out where he is. The fact that his cell phone is mistake for a spy gadget doesn't help.
  • The end of Robert A. Heinlein's Time Enough for Love involves the protagonist travelling back to the time of his own childhood and dealing with the difficulties thereby. Despite being a 2000+ year old pansexual incestuous time traveler speaking what, after 2000+ years, might as well be a foreign language in a very alien culture, he encounters no problems. However, his plan to escape having to fight in WWI is to hustle pool and flee to Brazil. He then realizes that that might get him killed by German or French agents as a spy.
  • In the horror novel Jago, a minor character is transported back in time fifty years, landing in the middle of World War II. The suspicious locals who find her decide she's a German spy who's just parachuted in, taking her modern clothes for some kind of Spy Catsuit... and the fact that she's wearing a swastika necklace in what was, in the 1990s, a relatively harmless act of teenage rebellion, really doesn't help her case.
  • In Johnny and the Bomb, both Bigmac and Wobbler are mistaken for spies when the main characters travel back in time to the Second World War. As in some other examples, the WWII people regard their modern technology as spy gadgets, especially a pocket radio. It doesn't help that the radio says "Made in Japan", or that Bigmac is wearing a German uniform.
  • In the third novel of the The Milkweed Triptych, Raybould Marsh barely escapes the End of the World as We Know It by traveling back in time to World War II. Just before he time-jumps, his friend hurriedly gives him his billfold so he'll have some ready cash. Unfortunately the money and identity cards are all from 1963, so he's quickly detained by the police on suspicion of being a German spy with badly-forged documents. This turns out to be an advantage through, as the authorities release him the next day in a Trick-and-Follow Ploy. As Marsh is an intelligence agent, but a British one and therefore familiar with London, he's able to escape their surveillance.
  • In Outlander, this is a huge problem for protagonist Claire in the first and second books, especially as she arrives in Scotland during the Jacobite period.
  • Played straight in the novel Timeline. An English knight suspects a shy "Irish" squire (in reality an American student from 1999) of being a French spy and challenges him to a joust to prove that he is not.note 
  • The Time Scout series doesn't say you'll be caught as a spy, but the results are the same. Get caught, get killed. Usually for apostasy or some such.
  • A frequent plot device in Harry Turtledove's Crosstime Traffic young-adult series. While not exactly time travel, the protagonists travel to alternate universes where historical events have departed from their own Future History. In most of the stories so far, they get mistaken for spies. For example:
    • In The Disunited States of America the protagonist is travelling with forged identity documents in a war zone and steals a uniform in order to infiltrate a military unit — any of which would get him executed for espionage had he been caught, even though that wasn't his intent.
    • In Curious Notions the protagonists are suspected of being double agents by both the Imperial German occupation government and the Triads in San Francisco due to the actions of their predecessors (selling slightly more advanced technology from the home timeline to the locals — against company rules precisely because it attracts undue attention from the authorities).
    • In The Gladiator the Crosstime Traffic organization is actually participating in espionage, attempting to subvert the victorious Communist government by reintroducing capitalist concepts to the population in a timeline where the USSR won the Cold War.
  • Occurs in Connie Willis' Doomsday Book when the main character travels to the 14th century and immediately falls sick with influenza. In her delirium she constantly talks in Modern English which none of the contemps can understand, leaving one character to suspect her of being a French spy (The Hundred Years War between England and France being in full swing at that time).
  • In Where were you, Robert?, by Hans Magnus Enzensberger, the (German) protagonist travels accidentally to 1956 Soviet Union. At the peak Cold War paranoia, it doesn't take long for intelligence officers to get an interest in this stranger and the incredibly advanced technology they find on him (such as a pocket calculator).
  • Invoked in Harry Potter and the Prisoner of Azkaban where Hermione tells Harry that they can't be seen by their past selves because they'll probably be mistaken for villains disguised with a polyjuice potion.

    Live-Action TV 
  • Played for Laughs in an episode of Boy Meets World, in which an accident involving a microwave oven sends Cory back in time to a warped version of The '50s. (It's All Just a Dream.) Notably, they don't get suspicious for any of the reasons listed above, but because he doesn't buy into McCarthyist paranoia and isn't deathly afraid of a Soviet invasion like everyone else in town. He also has knowledge he shouldn't have, such as exactly what Sputnik is (i.e. a harmless metal ball with legs instead of a Kill Sat).
  • In Buck Rogers in the 25th Century Buck is effectively a time traveler, having awakened after 504 years into a future he doesn't yet understand. Matters aren't helped by the fact that he is awakened by the Draconians, Earth's enemies, who install a tracking device on Buck's space shuttle to learn how to get through Earth's defenses. Buck is subsequently accused by Earth of being a Draconian spy, setting up the Clear My Name plot that dominates the second half of the pilot movie. Most of the episodes in the first season have Buck utilized as a spy by the Earth Defense Directorate precisely because he's not on the grid. Buck's frequently able to use his 20th century skills to throw 25th century opponents off guard.
  • Doctor Who:
    • Naturally this happens whenever the Doctor and his companions turn up in a war zone. In "The War Games" they're detained by British World War One soldiers and accused of being German spies. They then escape only to get caught by the Germans who plan to execute them as British spies. Later a British officer they've convinced of their bona fides gets his brainwashing restored and immediately accuses them of being German spies, to everyone's confusion as they're pretending to be the alien villains at the time. To cap this off the Big Bad also accuses them of being spies working for a rival. The only person who believes they are time travelers turns out to be a renegade Time Lord who's acquainted with the Doctor.
    • "Frontier in Space" plays the trope for longer than usual given that there's a Space Cold War and both sides think the Doctor and Jo Grant are working for their enemies. Then the Master shows up to further muddy the waters with fake records showing they are both known criminals.
    • In "The Masque of Mandragora", Duke Giuliano accuses the Doctor of being a spy, and proves himself a lot smarter than most villains by ordering his immediate execution. Another noble opposed to Giuliano fortunately rescues him.
    • In "The Talons of Weng-Chiang". Magnus Greel thinks the Doctor is a Time Agent sent to recapture him for his war crimes. Although at first he dismisses the possibility when told by his underling about the Doctor asking a lot of questions, saying that a Time Agent would already know the answers.
    • This is a plot point in "The Caves of Androzani". His unexplained presence on Androzani Minor leads Morgus to assume the Doctor is a spy for the President, leading to several fatal errors on his part.
    • In "Cold War", the Doctor and Clara materialize on board a Soviet nuclear sub. Naturally, the crew assumes they're Western spies, despite the TARDIS turning their speech into flawless Russian. This leads to an exchange where Clara says she doesn't even speak Russian... while speaking Russian. They decide to cut to the chase and admit they are time-travellers, since no other explanation would work.
    • "Spyfall" plays it much more literally than the show usually does, with the Thirteenth Doctor and her "fam" called in to help MI6 when intelligence agents around the globe are felled by an alien-connected conspiracy, complete with a Black-Tie Infiltration and Yaz and Ryan posing as reporters at one point.
    • In the spin-off K9 episode "The Cambridge Spy", a lightning strike sends Jorjie back to Cambridge in 1963. She's arrested as a Russian spy, and K9 and Starkey have to travel back to rescue her.
  • In the Eureka episode "Founder's Day", a bunch of characters from the present day appear at an army camp in 1947; the general in charge of the camp spends most of the episode chasing them around assuming they're spies.
  • This happens to Gary in an early episode of Goodnight Sweetheart. Knowing Himmler and Goebbels' hair colour is what did it; his claims to have seen it in a newsreel fall a bit flat because newsreels were monochrome. He decides to play it up and manages to convince his captors he is a spy, but a British one and not a German one as they'd assumed.
  • Outlander: When Claire Beauchamp Randall inexplicably travels from 1945 to 1743, she spends most of the first season warding off accusations of espionage. The Highlanders think she's a spy for the English or the French and the English think she's a spy for the French or possibly sent on behalf of the exiled Stuart king. It doesn't help that she inexplicably knows things before they "happen", due to their historical importance. Additionally, in the first book, Jamie notes that while she's fluent in multiple languages, she doesn't sound native in any of them, including English. However, what he considers an "odd" accent is merely due to her learning the language 200 years past the time he learned it.
  • Stargate SG-1. In "1969", the team finds themselves at the bottom of a missile silo in 1969, leading naturally to this assumption. It doesn't help that the interrogator asks them, in Russian, "Are you Russian spies?" and Daniel replies without thinking, "Nyet." O'Neill is not happy.
  • Star Trek: The Original Series
    • In "Tomorrow Is Yesterday", when the Enterprise accidentally travels back in time to Earth in 1969, Captain Kirk is considered a spy when he's caught infiltrating a U.S. Air Force base. (When an interrogator threatens to lock him up for two hundred years, Kirk ruefully acknowledges, "That ought to be just about right.")
    • In "Assignment: Earth", when the Enterprise is purposefully sent back in time to Earth in 1968, Kirk and Spock are arrested as spies when they're caught inside McKinley Rocket Base.
  • Supernatural: Justified in "Time After Time" given that it's World War II, and Dean is carrying a fake ID (an FBI badge 68 years out of date) and an electronic device (a mobile phone) displaying the words NO SIGNAL.
    Cop: You some kind of jerry spy?
    Dean: Jerry who?
    Cop: And a terrible one at that.
  • The Time Tunnel. In "The Day the Sky Fell In", Doug and Tony reveal that they are time travellers after being given truth serum, leading their captors to believe they must be professional spies who have been conditioned to spout nonsense when drugged.
  • In the Netflix series Travelers it is in fact the case that all of the Travelers are spies. A rogue member tries to sell the US government information about how they've been infiltrated by this conspiracy but forgot just how deeply that infiltration went.
  • Voyagers!: In "Sneak Attack", Jackie Knox mistakes Bogg and Jeffrey for Axis spies in Pearl Harbor on December 6, 1941.
  • Weird Science: In "By the Time We Got to Woodstock", Gary, Wyatt and Chett are mistaken for spies when they visit The Pentagon in 1969 as Chett reveals that he knows about the US Army secretly bombing Cambodia, Richard Nixon taping conversations in the Oval Office, J. Edgar Hoover being a crossdresser and the exploding cigars that the CIA sent to Fidel Castro.

  • Kids Praise: The seventh album involves two brief Adventures in the Bible: one visit to King David while he was still a shepherd boy, and another to the dedication of Solomon's Temple. Both times, the kids are mistaken for enemy spies, either requiring Psalty to explain, or requiring them to time-travel out of there before being attacked!

    Tabletop Games 
  • In the GURPS Infinite Worlds setting, this trope is played with due to the fact that Infinity Patrol agents routinely do become spies in the Alternate timelines they infiltrate, both to avoid the notice of the locals, as well as to hide from agents of rival Crossworld travelers from the Centrum timeline.

    Video Games 
  • In Back to the Future: The Game, Edna Strickland is convinced that Marty is a spy named Yako Smirnoff (partially because a different time traveller told her this.) Additionally, Arthur McFly is convinced that Marty is an FBI agent.
  • In Chrono Trigger, Crono and his companions are identified as spies by a mysterious prophet who recently turned up in the Kingdom of Zeal in 12,000 B.C. and predicted various events, including their arrival. The prophet himself turns out to be a time-traveling Magus, inverting the trope. That and it can be presumed that he avoids many of the mishaps of being thought as a spy despite his time-traveler status because he actually existed in that past time period and place(as a child) and thus knows the cultural details that the natives there would know.

  • Ophelia (a modern-day office worker) gets mistaken for a spy in a strip of Irregular Webcomic!, because she knows that the Nazis never planned to steal the British Crown Jewels.
