So you've been watching a new show for a few weeks now, you like the characters and are just getting comfortable with the routine of how things work. You tune in expecting another MonsterOfTheWeek when all of a sudden the writers pull a fast one.

This is done to either showcase something that's been teased at, raise the stakes, or [[GameChanger change the game]] somehow to keep things more interesting. It could also be [[FridgeBrilliance played subtly,]] introducing something that seems like a regular MonsterOfTheWeek plot, but [[ChekhovsGun later on goes on to define the main plot.]] The repercussions of this episode will continue to be important for the rest of the arc or even series.

The point when the Exposition stops and the real Plot begins. Usually falls on episode 7 or there about as it's halfway through the first 13-episode season, or 1/4 of the way through your 26-episode season if you get renewed. The logic behind this is relatively simple: if the show contains a MythArc, [[TheHerosJourney 1/4 of the way through a 26-episode season corresponds with the "Crossing The First Threshold" moment of the story (or the end of "Act 1" of the story), while 1/2 of the way through a 12/13-episode season corresponds with the "Approach the Inmost Cave" moment (or halfway through "Act 2", with the plot picking up steam until the end of the "Act 2".]] May extend to later seasons as well, as it is one of the few acceptable times to shift the [[StatusQuoIsGod Status Quo]].

Either as a result of, or a reaction to, this trope these events almost always take place during "Sweeps" period during which networks gather ratings data to support the advertising rates they charge for commercial airtime during their shows. With the average network show beginning its season in mid- to late September the seventh episode will normally air in November, the first "Sweeps" period. With many shows going into re-runs during the Christmas/New Years holiday, the 13th episode will typically be airing in February, the second "Sweeps" period.

'''''Warning. Examples are essentially [[SpoileredRotten Spoilers]] but since they're so early in the series, most are probably closer to LateArrivalSpoiler.'''''

Compare FirstEpisodeSpoiler and LateArrivalSpoiler.

'''''Unless otherwise specified, all examples actually land on Episode 7 exactly.'''''

* ''VisualNovel/{{Clannad}}'' - People are starting to forget [[{{Unperson}} Fuko]].

* ''Negima!?'': In the first anime, [[spoiler: Evangeline]] isn't revealed to be a [[spoiler: vampire]] until episode 6, and [[spoiler: Chachamaru]] to be a [[spoiler: robot]] until episode 7 (though at least she has some foreshadowing.) It happens even later in the manga, with the revelation not coming until after the 8th grade exams, which were episodes 12 and 13 in the anime.
* ''MacrossFrontier'': The first major space battle (earlier engagements were just small skirmishes), with the first Vajra capital ship making an appearance...folding through a [[NegativeSpaceWedgie fold fault]], which was supposed to be completely impossible. Then the ''Macross Quarter'' gets to show off why it deserves the first part of its name...basically, episode 7 seriously upped the ante in terms of action.

Furthermore, when she returns to the mamodo, this is where Zatch gets his reason and goal. His goal is to become a kind king.
* ''Anime/SaintSeiyaOmega'' has several. Despite people's belief it was a lighthearted series, several were shocked with the revelation that the director from Palestra is revealed as one of Athena's strongest Saints but has betrayed her and is sacrificing several young soldiers. Another twist involves in mid first season when a main member from the cast, Aria. is KilledOffForReal despite the previous series' NotQuiteDead. Several fans refused to believe she was killed and expected the next episodes to reveal she was alive. They were wrong.
* ''Anime/SoukouNoStrain'' looks like it's going to avert this with a fanservice filler episode, until Lavinia's antics accidentally land Emily in a garbage truck. Episode eight follows, with an almost-kiss, Sara meeting the other Emily, Carris having ADeathInTheLimelight, and Sara confronting Ralph only to be exposed to Lottie and the ''Libertad''.
* MÄR doesn't exactly have a twist on Episode 7 per se, aside from the fact that Snow exists (something you could figure out by watching the OP) but it is where the plot actually starts.

* ''Manga/TheDaughterOfTwentyFaces'' is ''very'' difficult to discuss without revealing [[EverybodysDeadDave what happens]] [[TrashTheSet in the]] [[HeroicBSOD sixth]] [[NotQuiteDead episode]].

[[folder:Live-Action TV]]
* ''[[Series/TwentyFour 24]]''

* ''Series/TheGoodGuys'': Jack kisses Liz and admits he's not over her.
* ''HeadOfTheClass'': the original premise had Charlie as a substitute teacher to a "gifted" class. Episode 6 featured the return of the original teacher and a permanent change in Charlie's status -- specifically, since this wasn't the last episode, he becomes permanent. The show does act as though he will leave until the literal last minute of the episode.
* ''Series/HowIMetYourMother''

* ''{{Series/PrimevalNewWorld}}'': The episode "Truth", while technically Episode 8, qualifies. It starts out reasonably normal with a Pachycephalosaurus coming through an anomaly. But then [[spoiler: after that is quickly resolved, Evan starts having flashbacks of his wife's death, thanks to the contents of a sneeze from the Pachycephalosaurus. In the following chaos of him hunting down an Albertosaurus that isn't there, it is revealed that the frozen ARC soldier who saved Evan when his wife was killed is Mac from an alternate timeline.

[[/folder]]

[[folder:Videogames]]
* Occurs in many ''Franchise/FireEmblem'' titles. Each game is divided up into 24~30 Chapters (excluding sidequests) that feel very much like a season of television or a ~26 episode series.
** In ''[[VideoGame/FireEmblemElibe Blazing Sword]]'', Chapter 7 is the first time we are introduced to the struggle between the Black Fang and Ninian and Nils, which is the major plot for most of the game. Eliwood and Hector, the game's [[PowerTrio other two protagonists]] make cameo appearances in the same chapter.
** In ''[[VideoGame/FireEmblemTheSacredStones The Sacred Stones]]'' Chapter 7 and 8 are essentially a two part chapter (the first to occur without going back to the main map) that ends Eirika's solo journey, reunites her with Ephraim, and gives the player the choice of who to follow for chapter 9 and onward. Chapter 7 also starts with a team rally, similar to the ones that usually start the final chapter in this series so you know its important.
** ''[[VideoGame/FireEmblemTellius Fire Emblem: Path of Radiance]]'': Chapter 7 is when the split-up Greil Mercenaries regroup. Some hours after the battle ends, [[spoiler:Greil fights and is killed by the Black Knight, forcing Ike to go from rookie mercenary to the company's commander at the beginning of Chapter 8]].
*** In ''Radiant Dawn'', Chapter 7 is when Tormod reunites with Sothe, and informs him that the evil doers in Begnion are led by a sect of Senators, not the Apostle Sanaki. The reveal of the rift in Begnion's leadership defines the politics of most of the game. Like the Blazing Sword example, this is really a teaser that becomes more important after the extended prologue.
** ''VideoGame/FireEmblemAwakening'': Chapter 6 reveals that Marth [[spoiler:is a woman who somehow knows of the future]]. Also introduces Validar, the BigBad from the [[TheTeaser Premonition Chapter,]] and has him meet the Fell Dragon Grima in human form for the first time who is [[ObviouslyEvil obviously]] the BiggerBad.

* ''Mother3'': The end of chapter 7 is when it is officially revealed that [[spoiler:Porky Minch]] is the Pigmasks' "King" responsible for all of the evil that has befallen the island (though anyone familiar with ''{{Earthbound}}'' has had plenty of clues by that point).
* ''VideoGame/FinalFantasyXIII'': Chapter 7 serves to introduce TheSixthRanger Fang, who finally reveals her and Vanille's role in causing the Purge, as well as to end the long-running arc of Hope's pursuit of revenge upon Snow. All in all, it marks the turning point where the [[RagtagBunchOfMisfits l'Cie]] stop working against each other and instead try cooperate henceforth.
* ''VideoGame/DreamfallTheLongestJourney'': Chapter 7 is the first one where we get to play as Kian and April, kicking the plot into gear. It also features April meeting the White Kin and the Guardian of the Balance, serving to integrate ''Dreamfall'' into the established mythology of ''VideoGame/TheLongestJourney''.
* For the first six episodes of {{Halo 4}}'s Spartan Ops The Infinity is using the Spartan 4s to try and learn more about Requiem, trying to keep a step ahead of the Covenant. Business as usual. But when episode seven rolled around, things on the Infinity get shaken up.
** [[spoiler: Prometheans Teleport aboard, and the Covies board her. To make things worse, the artifiact is telling requiem to tether Infinity through slipspace, so they can't get out of the range of the Promethean teleporters.]]

[[/folder]]

[[folder:Web Originals]]
* In Creator/DavidGonterman's ''American Kitsune'', the seventh chapter reveals that Serena and David are long lost siblings.
* Machinima/RedVsBlue - ends with a teaser stating a character would die in the next episode (which happens to be episode 7). Of course with the nature of this show, the character who dies comes back (as a ghost). His death pretty much sets off the plot of the rest of the series.
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/AvatarTheLastAirbender'': Episode 7 is part one of the the two-part Winter Solstice episode that introduces the Spirit World, Aang's ability to talk to past Avatars, and the coming of Sozin's Comet. The series jumps from "Let's take [[TheChick Katara]] to learn Waterbending" to "kill [[BigBad Ozai]] in a year or the world gets destroyed".
** ''WesternAnimation/TheLegendOfKorra'' has this in episode 6, the midpoint of the first 12 episode Season (or "Book"). The Pro-bending finals take place and the Equalists [[spoiler:destroy the arena (depriving Mako and Bolin of their home) and emerge publicly]]. At this point the series becomes much more intensely about the battle with the Equalists and the secrets of Republic City, and less about acclimating Korra. [[CaptainObvious Also the pro-bending subplot goes away.]]
* ''[[WesternAnimation/{{Thundercats 2011}} [=ThunderCats (2011)=]]]'': Episode 7, "Legacy" is a WhamEpisode, where we learn the origin of the Thundercats, their relationship with Mumm-Ra, and the game changes for the characters.

Lagoon Boy also gets captured, and Artemis fakes death to get closer to The Light and taking them down. Furthermore, we get a reason proper for the breakup of Superboy and Miss Martian as M'gann's ruthless treatment of "bad guys" [[WhatTheHellHero lead Superboy to break things up in disgust of what she was becoming]]. Additionally, it appears that M'gann tried to make Connor forget or repress his objections, by using her powers, which is doubly horrible, given Superboy's history of being mind controlled by villains and his origin as a mind-controlled tool of destruction. ]]

** In season two, episode 7 is when the Avengers first become aware of the Skrull infestation.

So you've been watching a new show for a few weeks now, you like the characters and are just getting comfortable with the routine of how things work. You tune in expecting another MonsterOfTheWeek when all of a sudden the writers pull a fast one.

This is done to either showcase something that's been teased at, raise the stakes, or [[GameChanger change the game]] somehow to keep things more interesting. It could also be [[FridgeBrilliance played subtly,]] introducing something that seems like a regular MonsterOfTheWeek plot, but [[ChekhovsGun later on goes on to define the main plot.]] The repercussions of this episode will continue to be important for the rest of the arc or even series.

The point when the Exposition stops and the real Plot begins. Usually falls on episode 7 or there about as it's halfway through the first 13-episode season, or 1/4 of the way through your 26-episode season if you get renewed. The logic behind this is relatively simple: if the show contains a MythArc, [[TheHerosJourney 1/4 of the way through a 26-episode season corresponds with the "Crossing The First Threshold" moment of the story (or the end of "Act 1" of the story), while 1/2 of the way through a 12/13-episode season corresponds with the "Approach the Inmost Cave" moment (or halfway through "Act 2", with the plot picking up steam until the end of the "Act 2".]] May extend to later seasons as well, as it is one of the few acceptable times to shift the [[StatusQuoIsGod Status Quo]].

Either as a result of, or a reaction to, this trope these events almost always take place during "Sweeps" period during which networks gather ratings data to support the advertising rates they charge for commercial airtime during their shows. With the average network show beginning its season in mid- to late September the seventh episode will normally air in November, the first "Sweeps" period. With many shows going into re-runs during the Christmas/New Years holiday, the 13th episode will typically be airing in February, the second "Sweeps" period.

'''''Warning. Examples are essentially [[SpoileredRotten Spoilers]] but since they're so early in the series, most are probably closer to LateArrivalSpoiler.'''''

Compare FirstEpisodeSpoiler and LateArrivalSpoiler.

'''''Unless otherwise specified, all examples actually land on Episode 7 exactly.'''''

It happens even later in the manga, with the revelation not coming until after the 8th grade exams, which were episodes 12 and 13 in the anime.
* ''MacrossFrontier'': The first major space battle (earlier engagements were just small skirmishes), with the first Vajra capital ship making an appearance...folding through a [[NegativeSpaceWedgie fold fault]], which was supposed to be completely impossible.

Furthermore, when she returns to the mamodo, this is where Zatch gets his reason and goal. His goal is to become a kind king.
* ''Anime/SaintSeiyaOmega'' has several. Despite people's belief it was a lighthearted series, several were shocked with the revelation that the director from Palestra is revealed as one of Athena's strongest Saints but has betrayed her and is sacrificing several young soldiers. Another twist involves in mid first season when a main member from the cast, Aria. is KilledOffForReal despite the previous series' NotQuiteDead. Several fans refused to believe she was killed and expected the next episodes to reveal she was alive. They were wrong.
* ''Anime/SoukouNoStrain'' looks like it's going to avert this with a fanservice filler episode, until Lavinia's antics accidentally land Emily in a garbage truck. Episode eight follows, with an almost-kiss, Sara meeting the other Emily, Carris having ADeathInTheLimelight, and Sara confronting Ralph only to be exposed to Lottie and the ''Libertad''.
* MÄR doesn't exactly have a twist on Episode 7 per se, aside from the fact that Snow exists (something you could figure out by watching the OP) but it is where the plot actually starts.

* ''Manga/TheDaughterOfTwentyFaces'' is ''very'' difficult to discuss without revealing [[EverybodysDeadDave what happens]] [[TrashTheSet in the]] [[HeroicBSOD sixth]] [[NotQuiteDead episode]].

* ''[[Series/TwentyFour 24]]''

* ''{{Series/PrimevalNewWorld}}'': The episode "Truth", while technically Episode 8, qualifies. It starts out reasonably normal with a Pachycephalosaurus coming through an anomaly. But then [[spoiler: after that is quickly resolved, Evan starts having flashbacks of his wife's death, thanks to the contents of a sneeze from the Pachycephalosaurus. In the following chaos of him hunting down an Albertosaurus that isn't there, it is revealed that the frozen ARC soldier who saved Evan when his wife was killed is Mac from an alternate timeline.

[[/folder]]

[[folder:Videogames]]
* Occurs in many ''Franchise/FireEmblem'' titles. Each game is divided up into 24~30 Chapters (excluding sidequests) that feel very much like a season of television or a ~26 episode series.
** In ''[[VideoGame/FireEmblemElibe Blazing Sword]]'', Chapter 7 is the first time we are introduced to the struggle between the Black Fang and Ninian and Nils, which is the major plot for most of the game. Eliwood and Hector, the game's [[PowerTrio other two protagonists]] make cameo appearances in the same chapter.
** In ''[[VideoGame/FireEmblemTheSacredStones The Sacred Stones]]'' Chapter 7 and 8 are essentially a two part chapter (the first to occur without going back to the main map) that ends Eirika's solo journey, reunites her with Ephraim, and gives the player the choice of who to follow for chapter 9 and onward. Chapter 7 also starts with a team rally, similar to the ones that usually start the final chapter in this series so you know its important.
** ''[[VideoGame/FireEmblemTellius Fire Emblem: Path of Radiance]]'': Chapter 7 is when the split-up Greil Mercenaries regroup. Some hours after the battle ends, [[spoiler:Greil fights and is killed by the Black Knight, forcing Ike to go from rookie mercenary to the company's commander at the beginning of Chapter 8]].
*** In ''Radiant Dawn'', Chapter 7 is when Tormod reunites with Sothe, and informs him that the evil doers in Begnion are led by a sect of Senators, not the Apostle Sanaki. The reveal of the rift in Begnion's leadership defines the politics of most of the game. Like the Blazing Sword example, this is really a teaser that becomes more important after the extended prologue.
** ''VideoGame/FireEmblemAwakening'': Chapter 6 reveals that Marth [[spoiler:is a woman who somehow knows of the future]]. Also introduces Validar, the BigBad from the [[TheTeaser Premonition Chapter,]] and has him meet the Fell Dragon Grima in human form for the first time who is [[ObviouslyEvil obviously]] the BiggerBad. Chapter 7 is when Emm gives Chrom the Fire Emblem to protect as she splits with the rest of the team to lead the war against Plegia.

* In Creator/DavidGonterman's ''American Kitsune'', the seventh chapter reveals that Serena and David are long lost siblings.
* Machinima/RedVsBlue - ends with a teaser stating a character would die in the next episode (which happens to be episode 7). Of course with the nature of this show, the character who dies comes back (as a ghost). His death pretty much sets off the plot of the rest of the series.

[[folder:Western Animation]]
* ''WesternAnimation/AvatarTheLastAirbender'': Episode 7 is part one of the the two-part Winter Solstice episode that introduces the Spirit World, Aang's ability to talk to past Avatars, and the coming of Sozin's Comet. The series jumps from "Let's take [[TheChick Katara]] to learn Waterbending" to "kill [[BigBad Ozai]] in a year or the world gets destroyed".
** ''WesternAnimation/TheLegendOfKorra'' has this in episode 6, the midpoint of the first 12 episode Season (or "Book"). The Pro-bending finals take place and the Equalists [[spoiler:destroy the arena (depriving Mako and Bolin of their home) and emerge publicly]]. At this point the series becomes much more intensely about the battle with the Equalists and the secrets of Republic City, and less about acclimating Korra. [[CaptainObvious Also the pro-bending subplot goes away.]]
* ''[[WesternAnimation/{{Thundercats 2011}} [=ThunderCats (2011)=]]]'': Episode 7, "Legacy" is a WhamEpisode, where we learn the origin of the Thundercats, their relationship with Mumm-Ra, and the game changes for the characters.

** "The Man Without Fear": Spider-Man learns Wilson Fisk is the Kingpin, TheManBehindTheMan for many of his past battles.
* For ''WesternAnimation/YoungJustice'',in season 2, we get one proper which reveals [[spoiler: Kaldur is a FakeDefector, and that the original 3 and Artemis are on a private mission to figure out The Light's partner. Lagoon Boy also gets captured, and Artemis fakes death to get closer to The Light and taking them down. Furthermore, we get a reason proper for the breakup of Superboy and Miss Martian as M'gann's ruthless treatment of "bad guys" [[WhatTheHellHero lead Superboy to break things up in disgust of what she was becoming]]. Additionally, it appears that M'gann tried to make Connor forget or repress his objections, by using her powers, which is doubly horrible, given Superboy's history of being mind controlled by villains and his origin as a mind-controlled tool of destruction. ]]
