* ''WesternAnimation/DannyPhantom'' - first appearance of [[BigBad Vlad Plasmius]].

* ''Anime/YuGiOhArcV'': The first in what would become a long list of {{Wham Episode}}s was episode 7. The first appearance of Xyz Summoning in the show, revealing that this series would utilize ''all'' Extra Deck summoning methods (whereas previous series ''[[Anime/YuGiOhZexal Zexal]]'' ignored Synchro summoning entirely), the first appearance of KnightOfCeberus and IdenticalStranger to the protagonist Yuya, the first mention of the mysterious Academia and their connection to the local MegaCorp... This was the episode that sparked the CerebusSyndrome the rest of the show is known for.

* ''Anime/{{Pokemon}}'': in the seventh episode, Misty is revealed to be a Gym Leader.

** Season 1 episode 8 reveals that Aquors performance in Tokyo didn't just end with them ranking last, they end up with ''zero votes'', showing how far behind they are compared to other school idols. In addition, this episode reveals [[spoiler:that the Third-Years Kanan, Dia, and Mari were in an idol group back in their Third Year, which failed to perform in Tokyo when Kanan apparently got stage fright]].

* ''Anime/MyHime'', episode 8. We learn what happens when a [=HiME=] is defeated.

* ''VideoGame/SpecOpsTheLine'': Chapter 8 (of 15) features the white phosphorous incident (the game's SignatureScene), which signals a massive shift in both genre and tone for the entire game.

* ''LightNovel/SevenSensesOfTheReUnion'': Clive (revealed in the next episode to be a shapeshifter) backstabs Haruto and leaves him for dead, though it's the next episode coupled with the previous episode that cultivates the major plot twist of the show. Senses can be used in reality and that Asahi's Prophet Art is actually [[RealityWarper a future-bending power]] that a group called Gnosis wishes to harvest from her.

* In ''Literature/{{Harry Potter}}'', Lord Voldemort's physical resurrection and open declaration of his quest to become the ruler of the wizarding world at the end of Book 4 arguably serves as a shift from the more lighthearted tone of the first four volumes with their clearly sperarated adventures of the year to the existential themes constantly present in the rest of the series.

* ''VideoGame/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 ''VideoGame/{{Earthbound}}'' and ''VideoGame/SuperSmashBrosBrawl'' has had plenty of clues by that point).

* Roughly halfway through the first season of ''VideoGame/TheWalkingDead'' (at the end of Episode 3), Lee discovers that [[spoiler:[[TheReveal Clementine's walkie-talkie ''isn't broken'']], and she has been communicating with someone who claims to know where her family are.]]

* 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.

** Season 11: [[UltimateEvil The Darkness]] is revealed to be [[spoiler: God's sister]]. Shortly after that, [[spoiler: Lucifer]] [[TheBusCameBack returns]], setting up a BigBadEnsemble.

* ''WesternAnimation/XMen'' has a couple:
