* In ''{{WebAnimation/RWBY}}'', [[TheBully Cardin]] shoving Jaune into one of Beacon's rocket-propelled lockers and launching it is [[ButtMonkey unfortunate, but still pretty funny.]] Two volumes later, [[spoiler: Pyrrha does the same thing to him as a form of non-violent PercussivePrevention before she heads off to her suicidal duel against Cinder.]] This time, it's heartbreaking.

* All of Sherlock's hectic behavior in ''Series/{{Elementary}}'' becomes less amusing after he's [[spoiler:diagnosed with Post-Concussion Syndrome]] in part due to his recklessness.

* In ''VideoGame/TheLegendOfZeldaTwilightPrincess'', whenever Link purifies a Light Spirit spring and frees the surrounding region of Twilight, [[TheImp Midna]], who rides on Wolf Link's back in the Twilight but must hide in his shadow in normal Hyrule, will playfully say "See you later!" before disappearing into his shadow. [[spoiler:She says this again at the end when she must return to the Twilight Realm while destroying the Mirror of Twilight, knowing fully well that this means she will never see Link again.]]

* ''WebVideo/MyLittlePonyTheMentallyAdvancedSeries'': Well not exactly a light moment Celestia tearing apart filly!Twilight's prized stuffed bumblebee, was meant to be just another element of BlackComedy in a show full of it. But in RDP: The Haunting, an [[spoiler: EldritchAbomination uses this experience, to brain wash her into aiding it]]

* In ''Disney/{{Tangled}}'' as [[spoiler:Flynn lies dying]] he whispers to Rapunzel "You were my new dream" referencing a light-hearted song from earlier in the film "I've Got A Dream".

* Tony Stark managed to shrug off his very-nearly-HeroicSacrifice at the end of ''Film/{{The Avengers|2012}}''. However, in ''Film/IronMan3'', it is shown that the incident has given him a very bad case of post-traumatic stress and paranoia which drives him to create more and more inventions in an attempt to safeguard humanity, neglecting food, sleep and Pepper.

* In ''WesternAnimation/StevenUniverse'', when Steven talked to Peridot for the first time in "Marble Madness", he talks about some of his friends to her. [[spoiler:This comes back to bite him when the people he mentioned become the target of Homeworld Gems to be taken into space.]]

* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'': In "Ponyville Confidential", the Cutie Mark Crusaders' first attempt at journalism for the ''Foal Free Press'' ends with them in embarrassing situations; Scootaloo falls into a mud puddle, Sweetie Belle models a gaudy outfit, and Apple Bloom finds her baby pictures. Later on, it's revealed that Featherweight secretly took photographs of these moments, and Diamond Tiara blackmails them for trying to back out of writing hurtful gossip by threatening to publish them in the paper if they do.

* The ''WesternAnimation/FamilyGuy'' episode "Screams of Silence: The Story of Brenda Q." is a VerySpecialEpisode about Quagmire's sister and her abusive boyfriend, who actually appeared two seasons earlier as a throwaway gag in "Jerome is the New Black".

* ''VideoGame/{{Undertale}}'' features a gag early on where examining Sans' book reveals that it's a joke book hidden in a quantum physics book, with a joke book inside the quantum physics book, with a quantum physics book behind that joke book... At first it seems absurd, but later we begin to discover that Sans is actually a time traveller.

* In ''Series/BreakingBad'', Walter laughs about a furniture store [[EarWorm jingle]] with a person he kidnapped. The furniture store is called Tampico, and as he eventually ends up [[spoiler: killing the person he kidnapped in self defence just as he about to let him go]] the next time they show the Tampico brand, it is quite a dark moment.

* In "Don't Let Me Go", Donkey's introductory song in Shrek The Musical, he sings, "You need a pal, my calendar's open!" to Shrek. Given the nature of the song and character, it's a silly plea to Shrek to take Donkey along with him. Cut to Shrek singing "Who I'd Be", where Donkey's line is repeated but in a much more somber context and is a more genuine attempt to reach out to Shrek and offer friendship; it's right after Shrek sings of being in the dark and alone for his entire life, before Donkey and Fiona showed him compassion.

* In ''Literature/Animorphs'', Rachel is initially simply more short-tempered than the others, causing Marco to refer to her as "Xena: Warrior Princess." However, as the book series goes on, she starts becoming more and more violent, culminating with her [[spoiler:going on a suicide mission that involves a lot of bloodshed.]]

* In EverymanHYBRID, A Day In The Life was a BreatherEpisode of sorts, until hidden clips in future videos paint a more sinister tone on the whole day.

* In ''WesternAnimation/SausageParty'', the song The Great Beyond plays. The first time it plays, it's bright and cheery, with the foods singing about their version of heaven and how their dreams are going to come true once they're chosen. But when it's played the second time after you've learned the [[CruelAndUnusualDeath truth]] [[ColdBloodedTorture about]] the Great Beyond, it becomes rather dark and creepy.
