  • Alpha Bitch: Alison before she died. After, Hanna sort of replaces her.

  • Asshole Victim: Alison wasn't exactly the nicest person around. Ultimately subverted, as Alison wasn't the "victim" after all.
    • Not that the real victim Courtney was much better
  • Based on a True Story: The author claims at the series is loosely based off her experiences on "...Philadelphia’s Main Line."
  • The Beautiful Elite: Everyone in Rosewood. At worst they would be Hollywood Homely.

  • Broken Bird: Aria
  • Brother-Sister Incest / Not Blood Siblings: Toby and Jenna.
  • Cassandra Truth: The girls telling Darren that a second A was tormenting them after Mona's death, and, more disturbingly, Ali desperately trying to convince her parents that Courtney switched their identities.

  • Deadly Prank: The Jenna Thing is based off this. The girls are convinced to play a prank on Toby involving a firework. It backfires leading to Jenna's blindness and Toby taking the fall for it.

  • The Dog Was the Mastermind: A's identity fits this because at first the girls suspect A is Alison but after she is discovered to be dead leading them to suspect Toby to be A. It is actually Mona who was supposed to be best friends with Hanna which comes as a surprise to them because they never considered her at all.

  • Everybody Knew Already: The Jenna Thing turns out to be this because Courtney lied about it. She claimed that no one else but them knew and swore them to secrecy. It turns out that Jenna and Toby also knew who was behind it. Mona also knew it about which contributed to her dislike of the girls because she had been friends with Jenna.
  • False Friend: Mona befriended Hanna only as a part of her elaborate revenge plot as A. After Mona's death this leaves Hanna devastated because she thought Mona was a good friend of hers.

    • Aria's father and his student Meredith were this
  • I Ate WHAT?: Aria is a vegetarian, upon realizing in horror on her second week in Iceland that she ate a puffin.
  • Irony: The reason that Alison's parents hid Alison's twin sister, Courtney from the world was because they thought that Courtney was crazy. Tragically, it turned out that Alison, their "perfect little girl", was the one that would go around blackmailing people, ruining lives, tearing apart families, and killing people without even showing the slightest sign of remorse. The worst part? Their "perfect little girl" never would have gone on her rampage had she not been accidentally subjugated to the lifestyle that her sister had grown up in—the one that they decided to put her through.
    • It gets worse It turns out that Courtney was never the crazy one in the first place, it was Alison who purposefully made it seem like Courtney wanted to kill her in order to get her out of the way.
  • Informed Judaism: Hanna is revealed to be Jewish in Pretty Little Secrets. There were no indications prior to this nor has it been brought up since.

  • Keeping Secrets Sucks: The entire premise of the books.
  • Les Yay: Invoked by Alison to manipulate Emily.
  • Lipstick Lesbian: Maya, Emily and Trista.
  • Luke, I Am Your Father: Zig-zagged. Spencer thinks she might be adopted and finds a woman who claims to be her birth mother, but then it turns out that her parents are hers, and the woman she thought was her mother was in fact her gestational surrogate trying to get more money from the Hastings. Also, in a more straight example, Spencer's dad is Alison and Courtney's father.
  • Mama Bear: Hanna's mom is rather protective of her. Even Darren lampshades this.
    • Emily who thinks the New A is still Ali is willing to forgive Ali if she apologizes, until the moment she gets texts threatening her new born daughter
  • Man Behind the Man: The girls first think A is Alison which turns out to be wrong because it is Mona. However, Mona knew nothing about Courtney and after her death a new A appeared. It is revealed to be Alison who was actually behind it this time and she was far more malicious as A than Mona had ever been since she killed Jenna and Ian.
  • Manipulative Bitch: Courtney proves to be very skilled at manipulating other people. She was good at getting her friends to tell her their secrets.

    • Mona proves to be very skilled with this using her intelligence to plan the whole A scheme and befriend Hanna only for the purpose of taking her down later.

  • Woobie, Destroyer of Worlds:
    • Alison. Yes, she was already a jerk before her twin sister Courtney stole her identity but, still let's recap her life, shall we? throughout her childhood, her deranged twin sister, Courtney hated(a feeling that was initially one-sided) her and repeatedly expressed her desire to kill Alison and steal her life. Then, at seven years old Courtney tries to drown her telling Alison that " You don't deserve to be Ali. I do." and then she has to deal with keeping her sister a secret, and also, living with the person who not only wants to be her, but who had also tried to kill her. Then Courtney steals her life. and gets her two best friends for who-knows-how-long to hate Alison. And so Alison is forced to go to insane asylums, repeatedly ignored for all her attempts to tell the truth. For at least 2 years . Its really no wonder she did what she did. Then it's revealed in Ali's Pretty Little Lies It was Ali who hated Courtney because she was more popular and constantly attacked her and forced her to pretend to be her, until Courtney snapped and tried to strangle her allowing her to frame Courtney as insane when she really wasn't, This lessens her woobie factor.
    • Courtney even more so. Alison would force her to trade places with her so she could be the more popular one. Alison grew even more jealous and told her parents that Courtney threatened to harm her. When Courtney tried to say that Alison was the one who said so (which she did) it only made her come off as the crazy one. Courtney was wrongly diagnosed as a paranoid schizophrenic, and spent three years of her life in a mental hospital at the age of nine. Her parents sort of forgot about her and treated her like she was unwanted when she came home to visit, staying in a dinky guestroom and not being allowed outside. Her family even changed their last name from Day-DiLaurentis to DiLaurentis, because of the shame of having a child in a mental institution. Is it any wonder Courtney wanted to be free and have her old life back? Years later, after switching places with Alison, it turns out to be all for naught. They get into a fight one night. Courtney reveals that she just wants to have a sister again, that she misses the time where they loved each other. Alison reveals that she wants to kill Courtney but she can't. Then Alison's accomplice comes giving her motivation, Alison shoves her into a hole built for the gazebo, Courtney bangs her head on something hard, and she is buried alive.
  • Wicked Stepmother: This is subverted with Isabel because Hanna dislikes her mainly out of her jealously for her father finding a new family and preferring them to her.
  • Your Cheating Heart: Aria's father, as well as all the girls except Hanna at some point.
    • To be more specific — Wren and Ian both cheat on Melissa with Spencer. Emily cheats on Ben with Maya, then later cheats on Maya with Trista. Aria cheats on Sean with Ezra.
    • Spencer's father. He had an affair with Alison's mother and is actually Alison's father.
    • Ella's boyfriend, Xavier, tries to cheat on her with Aria, who does not take it well.
