History Main / YourSonAllAlong

* ''Film/NoTimeToDie'': [[spoiler:Just as Film/JamesBond is about to [[HeroicSacrifice let himself die]] in the missile strike on the IslandBase at the end, Madeleine Swann tells him that Mathilde "does have [his] eyes", to which he answers "I know..." before [[TheHeroDies perishing]].]]

* ''Literature/TheAmazingAdventuresOfKavalierAndClay'': [[spoiler: Tommy's parentage, while known to the reader, was unknown to Joe until Rosa and Sam revealed the truth.]]
* Inverted in ''Literature/TheMayorOfCasterbridge''. Michael Henchard, the title character, drunkenly sells his wife Susan and infant daughter Elizabeth-Jane to a sailor, Richard Newson. Two decades later, Newson is lost at sea and Susan returns to Henchard, bringing Elizabeth-Jane along with her. It is only upon ''Susan'''s death that Henchard learns that [[spoiler:Elizabeth-Jane is ''not'' the same child he gave up, but a different child fathered by Newson, Henchard's daughter having died a few months after the sale.]]

* In the penultimate episode of ''Series/TheOfficeUS'', [[spoiler:Angela reveals to Dwight that he is the real father of her toddler son Phillip after he and Angela had one last fling a month before her wedding to the senator]].
* ''Series/{{Outlander}}'': Brianna Randall Fraser is raped by pirate Stephen Bonnet on the same night that she and her fiancé Roger [=MacKenzie=] consensually had sex a few hours earlier, and when she becomes pregnant it's unclear which of them is the biological father of her son Jeremiah. It doesn't help that he turns out blond like Bonnet rather than redheaded like Bree or brunet like Roger. Regardless, Roger promises to raise Jemmy as his own son when he marries Bree. Later, Jemmy demonstrates stronger than usual time traveler abilities, suggesting that he was Roger's biological son all along since both Bree and Roger are time travelers, and this is cemented when he develops the same hereditary mole on his head as Roger.

* ''Series/ShakespeareAndHathawayPrivateInvestigators'': A GenderFlipped example in "Ill Met by Moonlight", [[spoiler: Lady Bede had an ArrangedMarriage that became a SexlessMarriage to escape her tyrannical parents. She was impregnated with her daughter by the gardener, who remained unsuspecting and worked with her family for years.]]

* ''VideoGame/DevilMayCry5'': Heavily {{implied|Trope}} by several dialogue lines. In the ''Visions of V'' manga, Griffon speculates and tells [[spoiler:V that Nero is a blood descendant of Sparda, either the child of Dante ''or'' Vergil. The game eventually confirmed the latter, and revealed V as the human half of Vergil. But because Vergil still needed Dante to spell it out for him in the end (as quoted below) in order to remember his visit to Fortuna from "a long time ago", this created the retroactive implication that V and Nero spent most of the game unaware that they are father and son. Likewise, Vergil was "preoccupied" as Nelo Angelo, so the only logical conclusion for him was that Nero is Dante's son]].
-->'''[[spoiler:Vergil:]]''' Nero is ''my'' son?\\
'''[[spoiler:Dante:]]''' Yeah, dumbass. You can't remember through that thick skull of yours?\\
'''[[spoiler:Vergil:]]''' Well, well... That was a long time ago.

* A rare female version can be found in ''VisualNovel/UminekoWhenTheyCry'' when it's confirmed in Ep 8 that [[spoiler: Battler's biological mother isn't Asumu but Kyrie. A baby switch was made by Rudolf when Asumu's child was a stillbirth, as he thought it would be easier since he and Asumu were married while Kyrie was a lover.]]

* Throughout the first half of ''WesternAnimation/TheVentureBrothers,'' Dermott Fictel is assumed to be the illegitimate son of [[TestosteronePoisoning Brock Samson]]; but in Season 4 it's revealed [[spoiler: he's actually the third Venture brother, and [[FamilyRelationshipSwitcheroo his mother isn't even his actual mother, but his grandmother]]]].
* In ''WesternAnimation/TheAngryBirdsMovie2'', Zeta drops two bombshells in succession. First, she tells her ex-fiancé Mighty Eagle that Debbie is her daughter. As the main cast gasps in surprise, she then says, "''Our'' daughter". This shocks ''everyone'' who hears this, especially Debbie and Mighty Eagle.

* While both V and [[spoiler:Vergil]] from ''VideoGame/DevilMayCry5'' are aware that Nero has the blood of Sparda within him, they naturally assume that it's Dante who fathered him, when in reality, [[spoiler:it is Vergil himself who is Nero's father]]. And man oh man, is it ever a shock for [[spoiler:Vergil]] when he finds this out.

* In ''Series/GeneralHospital'', Alan and Monica spent several years believing that their son AJ was the result of Monica's affair, before finding out that he was Alan's son after all. Unfortunately, crucial bonding time had been lost between the two, resulting in years of AJ being TheUnfavorite (to the son conceived during ''Alan's'' affair) and him being an alcoholic failure. Decades later, AJ (correctly) suspected that he was the father of Carly's unborn child, but she lied and told him that his brother Jason was, fearing that either AJ or her boyfriend Tony would take the child away from her. Years later, Jason's girlfriend Robin finally told AJ the truth.

* ''Series/MyNameIsEarl'': Joy believes that Li'l Chubby is Dodge's father, but she's afraid of him, because she witnessed him mistreating another woman who claimed to be pregnant with his child. Earl wants her to come forward to Chubby, because he can see that Dodge (and Earl Jr.) are suffering due to their living in PerpetualPoverty. Joy tells him to drop it, but he persists, and gets a DaddyDNATest, against all odds (with a little help from Darnell). The test shows that Dodge is ''not'' Li'l Chubby's... but Earl's. As it turns out, Earl and Joy conceived him at a Halloween party, and did not recognize each other afterwards. For the six years that they were married, Earl had been led to believe that Dodge's biological father was a stranger from a concert. In another AssPull, the test also shows that [[ChocolateBaby Earl Jr]]. is ''not'' Darnell's, as previously thought. It's never stated who his father actually is, due to the series being canceled, though WordOfGod says it was supposed to be a celebrity.

* In ''Series/{{Dallas}}'', both Sue Ellen and JR believed that her son was the result of an affair with Cliff Barnes, JR's arch-rival. When it's discovered that Cliff might have a hereditary condition that could be passed to offspring, it is found out that John Ross III was, in fact, JR's son.
* ''Series/ShakespeareAndHathawayPrivateInvestigators'': A GenderFlipped example in "Ill Met by Moonlight", [[spoiler: Lady Bede had an ArrangedMarriage that became a SexlessMarriage to escape her tyrannical parents. She was impregnated with her daughter by the gardener, who remained unsuspecting and worked with her family for years.]]
* ''Series/{{Hannibal}}'': Veteran SerialKiller Lawrence Wells' first victim was his mistress's husband, and her last victim, forty years later, was her son. He intended it to be a final blow against the mistress, but has a VillainousBSOD when he learns that he, not her husband, was the true father.
-->'''Will:''' You thought the woman you loved was having Fletcher Marshall's baby when she should've been having yours, but you got it the wrong way around! Eleanor ''chose'' to raise him as Fletcher Marshall's child ''rather'' than yours... so, maybe, ''she saw what's in your heart.''
* ''Series/{{Outlander}}'': Brianna Randall Fraser is raped by pirate Stephen Bonnet on the same night that she and her fiancé Roger [=MacKenzie=] consensually had sex a few hours earlier, and when she becomes pregnant it's unclear which of them is the biological father of her son Jeremiah. It doesn't help that he turns out blond like Bonnet rather than redheaded like Bree or brunet like Roger. Regardless, Roger promises to raise Jemmy as his own son when he marries Bree. Later, Jemmy demonstrates stronger than usual time traveler abilities, suggesting that he was Roger's biological son all along since both Bree and Roger are time travelers, and this is cemented when he develops the same hereditary mole on his head as Roger.
