History Series / YoungSheldon

* TheScrappy: Mary gets a lot of hate for her forcing her Christian beliefs on everyone and for her [[ParentalFavoritism blatant favoritism of Sheldon.]]

** Yet another pregnancy arc kicks off in "A Solo Peanut, a Social Butterfly and the Truth", this time involving [[spoiler:Georgie and Mandy. Mandy tells Georgie that she's pregnant, but again, Georgie doesn't seem to have any children in ''The Big Bang Theory''. So either it's a {{retcon}}, a false positive, someone else is the father (jossed in the following episode), she takes sole custody or the child is miscarried/aborted/put up for adoption (also jossed, as Mandy wants to keep the child).]]

* AdultFear:
** In "A Therapist, A Comic Book, and A Breakfast Sausage", Sheldon wanders off while at the therapist office. Although nothing bad happens to him, his parents are worried sick, and when he returns home there are police cars there.
** In "A Crisis of Faith and Octopus Aliens", Mary reacts badly to a neighbor's girl dying in a car crash. She's worried that it might happen to Georgie, who is about the same age and is just starting to learn to drive.
** In [[Recap/YoungSheldonS3E01QuirkyEggheadsAndTexasSnowGlobes "Quirky Eggheads and Texas Snow Globes"]], Mary worries that Sheldon's behavior might be a sign of mental illness, especially after [[spoiler:Dr. Sturgis, who had similar affectations, got sent to a psychiatric hospital.]]

** In "David, Goliath, and A Yoo-Hoo from the Back", Sheldon stands up to bully Jason Davies by using a makeshift slingshot and citing David and Goliath as inspiration. David actually used a sling, which is a completely different weapon than a sling''shot'' and is a lot more dangerous to boot. While this is a common misconception, someone as smart as Sheldon should know better. He has been shown to have an understanding of the Bible even though he doesn't believe in it.

** In "David, Goliath, and a Yoo-Hoo from the Back" Sheldon accidentally starts a fight between school bullies Jason Davies and Tommy Clarkson, Sheldon steps in to defend Tommy with a slingshot a la David and Goliath[[note]]Ignoring the fact that David used a sling, not a sling''shot'', which is a totally different and more dangerous weapon.[[/note]]. The slingshot is ineffective[[note]]Using safety goggles as as ImprovisedWeapon[[/note]] and Sheldon is chased down and stuffed in a locker overnight as a result.

* TheFriendsWhoNeverHang: A family variation. Among the members of the Cooper family, Sheldon and Georgie seldom interact with each other. In fact, "A Slump, a Cross and Roadside Gravel" is the only episode (as of this writing) to feature the two spending a significant amount of time together without the others as an intermediary.

** Season two episode "An 8-Bit Princess and a Flat Tire Genius" has Georgie getting a job as a mechanic at Herschel Sparks' garage. This is mentioned in a few more episodes, but in season three's "Pongo Pygmaeus and a Culture that Encourages Spitting", Georgie gets a job at Coach Ballard's sporting goods shop, with his old job not being mentioned, and Herschel doesn't appear at all in season three. This abandonment, along with Herschel's disappearance, is likely due to Creator/BillyGardell's commitments as the lead in ''Series/BobHeartsAbishola''.

** Georgie and Jana broke up in the third season due to Georgie wanting to see other girls. Season four ignores this and the two are back together. Only for them to part ways again following a [[spoiler:pregnancy scare]] as Georgie told her that he didn't want to get married, but what he meant to say was he was hoping not to have a shotgun wedding, but then, Georgie and Jana are together again in [[Recap/YoungSheldonS4E15AVirusHeartbreakAndAWorldOfPossibilities "A Virus, Heartbreak and a World of Possibilities"]]. They break up for real in "Potential Energy and Hooch on a Park Bench".

* AdaptationDyeJob: Mary and Missy are blondes in this show, instead of brunettes like in ''The Big Bang Theory''. Mary also has different colored eyes, as Zoe Perry has blue eyes while Laurie Metcalf's eyes are brown.

** In "David, Goliath, and a Yoo-Hoo from the Back" Sheldon accidentally starts a fight between school bullies Jason Davies and Tommy Clarkson, Sheldon steps in to defend Tommy with a slingshot a la David and Goliath[[note]]Ignoring the fact that David used a sling, not a sling''shot'', which is a totally different and more dangerous weapon.[[/note]]. The slingshot is ineffective and Sheldon is chased down and stuffed in a locker overnight as a result.

* DoubleStandard,Abuse,FemaleonMale: Missy likes a boy, who doesn't return her feelings. She throws a ball at him. Perfectly acceptable, of course...

** George Coooper Sr. canonically passes away in 1994. If the series timeline remains constant at one year per season[[note]]Season one takes place in 1989, season two takes place in early-to-mid 1990, season three seems to begin in mid 1990 and end in mid 1991, season four covers the rest of 1991, possibly going into early 1992[[/note]], this will most likely occur sometime in season six.

* TravellingSalesmanMontage: In "Quirky Eggheads and Texas Snow Globes", Georgie buys a failing store's inventory of Texas snow globes and goes door to door trying to sell them. The first time he tries it, he gets rejected every time, even by his own grandmother. The second time, however, he becomes successful after playing to his customer's memories of the last time it snowed on Texas.

* TenMinuteRetirement: In "An Existential Crisis and a Bear That Makes Bubbles", Sheldon abruptly changes majors from physics to philosophy. But just as Prof. Linkletter is signing the form to make it official, the sight of a bubble convinces Sheldon to stay in physics.

** The third season ended with [[spoiler:Dale being at odds with Connie and firing Georgie, with the two egging his store as revenge.]] In the fourth season premiere, [[spoiler: Dale makes peace with both of them and rehires Georgie, even after finding out that they egged his store.]]
** Georgie and Jana broke up in the third season due to Georgie wanting to see other girls. Season four ignores this and the two are back together. Only for them to part ways again following a [[spoiler:pregnancy scare]] as Georgie told her that he didn't want to get married, but what he meant to say was he was hoping not to have a shotgun wedding, but then, Georgie and Jana are together again in "A Virus, Heartbreak and a World of Possibilities". They break up for real in "Potential Energy and Hooch on a Park Bench".
* AcronymAndAbbreviationOverload: In S2 E22 "A Swedish Science Thing and the Equation for Toast", George starts charging Georgie a P.I.M.A. ("Pain In My Ass") tax for buying cable TV and not sharing it with the rest of the family. Justified, as Mary probably wouldn't approve of George swearing at Georgie.

** In "Quirky Eggheads and Texas Snow Globes", Mary worries that Sheldon's behavior might be a sign of mental illness, especially after [[spoiler:Dr. Sturgis, who had similar affectations, got sent to a psychiatric hospital.]]

** At the end of "A High-Pitched Buzz and Training Wheels", Sheldon vows that, no matter what he's been going through, he'd never be irritating or abusive to his friends and loved ones. Anyone who's watched ''The Big Bang Theory'' knows how well this stuck.

** "A Brisket, Voodoo and Cannonball Run" has George and Connie putting their differences aside, but in subsequent episodes, they still engage in SnarkToSnarkCombat and Connie still sees him as a disappointing son-in-law.

* AlternateRealityEpisode: S4 E17 "A Black Hole" shows three alternate realities:

* OutgrowingTheChildishName: In "Freshman Orientation and the Inventor of the Zipper", Missy wants to be called "Melissa" now that she's in middle school. She then reverts back to "Missy" in the next episode with no explanation.

** Georgie and Jana broke up in the third season due to Georgie wanting to see other girls. Season four ignores this and the two are back together. Only for them to part ways again following a [[spoiler:pregnancy scare]] as Georgie told her that he didn't want to get married, but what he meant to say was he was hoping not to have a shotgun wedding, but then, Georgie and Jana are together again in "A Virus, Heartbreak and a World of Possibilities".
