History Series / OneOfUsIsLying

** Addy is the conflicted (influenceable , dependent of her boyfriend [[CharacterDevelopmentat least for a while]])

* HairContrastDuo: PlayedWith but subverted with Bronwyn and Addy. In-Universe, people think about the Bayview 4 theory (concerning Simon's murder) that Bronwyn is the calculating BrainyBrunette while Addy is the innocent DumbBlonde but the story shows they have HiddenDepths (Bronwyn is TheAce as everyone thinks and Addy demonstrates she has some wits).

* BigBad: [[spoiler: Jake is the killer/stalker.]]

* FourTempermentEnsemble: The four main protagonists:

'''Kelly:''' Right, where Bronwyn's the Brains? Cooper's the Brawn, Nate's the Badass, and Addy's the Blonde?\\

* AdultFear: Nate’s a teen drug dealer whose house has a stack of overdue bills. His father is an addict who isn’t even awake when he comes home. When the dad is barely lucid enough to ask how his son is, Nate lies and doesn’t tell him about the murder investigation.
** When [[spoiler: his mother]] returns, they think he might be the killer, but that they screwed him up so much that it is their fault, not his.

* BeautyBrainsAndBrawn: Discussed and PlayedWith:

** But actually both Cooper and Nate share the Brawn role (fitting two different stereotypes for this role) as Cooper is the jock while Nate's the resident bad boy.

'''Addy:''' [[InvokedTrope Most actually say Beauty.]]\\

->'''Cooper:''' Same. The Baywiew four theory.
'''Kelly:''' Right, where Bronwyn's the Brains? Cooper's the Brawn, Nate's the Badass, and Addy's the Blonde?
'''Addy:''' [[InvokedTrope Most actually say Beauty.]]

->'''Cooper''': Same. The Baywiew four theory.
'''Kelly''': Right, where Bronwyn's the Brains? Cooper's the Brawn, Nate's the Badass, and Addy's the Blonde?
'''Addy''': [[InvokedTrope Most actually say Beauty.]]

* HairConstrastDuo: PlayedWith but subverted with Bronwyn and Addy. In-Universe, people think about the Bayview 4 theory (concerning Simon's murder) that Bronwyn is the calculating BrainyBrunette while Addy is the innocent DumbBlonde but the story shows they have HiddenDepths (Bronwyn is TheAce as everyone thinks and Addy demonstrates she has some wits).

* ShipTease: Nate and Bronwyn.
** Brutally subverted with Addy and TJ. He liked her at first, but between her obsession with Jake and her later suspecting him of murder, she eventually drives him away.

* AbusiveParents: Simon’s mom treats his ''funeral'' as a way to further her political career.

* AdaptationalAngstUpgrade: As a result of Cooper's sexuality no longer being a big reveal, his relationship with Kris is changed to [[spoiler: Cooper lying to Kris about his age, claiming to be in college.]]

** [[spoiler: Part of Simon's reason for creating AboutThat is because he lost Jake as a friend.]]

* AdaptationalJerkass: Zigzagged. Maeve in the books was always on Bronwyn’s side and would have never [[spoiler: given the hard drive to the police, knowing it would out Cooper.]] However, she still loves her sister and goes to many lengths to defend Bronwyn.

* AnAesop: Lying to give people an image of who you are instead of being yourself isn't good. Be honest and the people who matter will stand by you.

* BecameTheirOwnAntithesis: Vanessa goes from hating Simon for how he post about people to hurt them to posting about Addy, Bronwyn, Cooper and Nate all the them, right up to the finale.

* TheBigDamnKiss: Nate and Bronwyn has this...about seconds before Nate [[spoiler: is arrested for Simon's murder.]]

* BittersweetEnding: [[spoiler: Jake is exposed as Simon's killer and the charges against Nate are dropped, but Jake ends up being shot while struggling over a gun with Cooper, Addy, and Janae, leading to a cover-up. Nate decides to stay away from Bronwyn, and everyone is avoiding each other while still being bullied and harassed by Vanessa via Instagram. Then, they all get a threatening text from SimonSays, stating that they should do what he wants or he'll reveal their secret.]]
* CompositeCharacter: Vanessa is still the AlphaBitch she was in the books, but she also appears to take on a lot of Olivia’s stuff. She and Addy are superficially friends before her secret is revealed, and Vanessa is effectively the ‘second option’ for a boy who likes one of her friends more. She still dates Jake after the breakup.

* DarkSecret: Nate pretends that [[spoiler: his mother is dead, when in fact she is alive. She also has a host of mental illnesses and addictions that resulted in her abandoning him with his dad.]]

* DisproportionateRetribution: Simon created his blog in order to take down people at school because [[spoiler: he used to be friends with Jake, who ditched him once he got abs.]]

* FreudianExcuse: Simon was friends with Jake up until Jake physically developed and started hanging out with the guys who used to bully them. When Simon called him out on it, Jake abandoned him for them. This eventually led to the creation of Simon's AboutThat blog.

* {{Irony}}: Vanessa, as revealed in a flashback, hated Simon for what he did with AboutThat, yet she ends up becoming Simon at the end by posting about the others and calling them murderers on her Instagram.
* MoodWhiplash: Nate and Bronwyn's kiss in the finale is very romantic...until an angry Janae interrupts to tell them that Jake doesn't have the XBOX in his room and to stop kissing.
* NeverMyFault: Simon hates Nate because Nate sold [[spoiler: Janae]] the drugs they used to overdose. [[spoiler: Simon completely ignores that finding him and Maeve together was what triggered Janae to buy drugs in the first place, that she may have deliberately overdosed, and that Nate is the one whose first aid probably saved her life.]]

* PetTheDog: After learning of [[spoiler: Janae's overdose, Simon goes over and apologizes to her for going after Maeve.]]

* TheReasonYouSuckSpeech: TJ gives one to Addy at the Homecoming Dance after she reveals that she thinks he killed Simon.

* TheReveal: [[spoiler: Janae was the one who was revealing their secrets at first on Simon's AboutThat blog. She did it because she genuinely thought one of them killed Simon. She eventually had her access taken away from her.]]

* UnwittingInstigatorOfDoom: Janae gave Simon the idea for the AboutThat blog when she teased him about his past friendship with [[spoiler: Jake.]] After hearing him rant on and on about how fake everyone at their school is, she jokingly tells him to make an app or blog exposing them for who they are.

* BecameYourOwnAntithesis: Vanessa goes from hating Simon for how he post about people to hurt them to posting about Addy, Bronwyn, Cooper and Nate all the them, right up to the finale.
