Willa Fitzgerald's character was originally named Harper but was changed when the official pilot script was written.
In the first-season finale, it is revealed that Audrey and Piper exchanged letters months prior to the murders, which indicate that she was connected to the killings.
In the second-season Halloween special, he partners with Stavo to create a horror graphic novel, and goes to an island to reach the mystery of the murderess Anna Hobbs, where they (and the rest of the second season survivors) are stalked again by another killer.
Kieran is a new kid in Lakewood, after losing his mother and his stepfather in a car accident before the series, and grows a special bond with Emma in the first season.
He is ultimately arrested and sentenced to life in prison; however, he is murdered by the new killer in the second-season Halloween special episodes.
She is the daughter of the town's mayor Quinn Maddox, with whom she has a strained relationship (intensified after learning he had been illegally dealing with Jake, and had also covered up the death of a drug addict friend of Brooke's mother).
Initially appearing shallow, Brooke is gradually shown to be more kinder and softer than her previous image suggested after her friend Riley becomes a victim to the killer.
Brooke is repeatedly attacked throughout the first season in a variety of settings – a theatre stage, a bowling alley, and a freezer in her garage – but manages to survive each encounter.
In "In the Trenches", Emma, Noah, Brooke, and Jake find an injured Will at an abandoned bowling alley, and are later rescued.
Before the series begin, Kieran moves in with him after his mother (Clark's ex-wife) dies in a car crash with her new husband.
It turns out that Maggie was nicknamed "Daisy" and was the girl that Brandon James was supposedly obsessed with, and started his killing spree because of.
It is discovered near the end of the season that Maggie became pregnant because of her fling with Brandon, and she and her family left town to have the baby, who was given up for adoption at birth.
Jake is a jock at George Washington High who always makes crass jokes and loves being foolish, to the consternation of many people.
In the second-season premiere, he is kidnapped, hanged upside down in a barn, and killed with a scythe, his stomach splitting open.
He is shown to like drawing Emma and her friends covered in blood, which is revealed to be a part of a horror graphic novel he is creating.
However, during a school lockdown after Jake's body is found during an assembly, Audrey quickly accuses him of being involved with the murders and reveals to the other students his drawings on his iPad.
In the second-season Halloween special episodes, Stavo is shown to have a burgeoning career in horror graphic comics, and starts a partnership with Noah as a result.
Portrayed by: Bobby Campo Seth Brandon was a teacher at GWH who had a secret (and illicit) relationship with Brooke Maddox.
He is later suspected of the murders when incriminating evidence is discovered in his classroom, as well as the fact that he had changed his name and moved to Lakewood after one of his previous students was found dead.
Later, when Brooke attempts to find Jake, Seth is tricked by her into chaining himself to a bed at a hotel room, under the guise of another affair.
Later, he is discovered to have buried his wife's drug-addict friend's body after the man had a fatal overdose; however, this is filmed and his daughter Brooke briefly suspects him of murdering her mother.
Riley then succumbs to her wounds on the rooftop of the sheriff station, whilst Noah (who called her) witnessed her death.
As a result, he suffered psychological trauma and became an alcoholic, contributing to his departure from his family (along with the revelation that Maggie had been involved with Brandon before the 1994 killings).
After learning his daughter Emma survived another similar set of murders, Kevin returns to Lakewood and tries to reconnect with her.
In the second-season Halloween special episodes, he is shown at the grave of Kieran Wilcox, implying some involvement in his death.
Tina appears proper and polite, but has a grifter’s sense of self-reliance, as she only took in Kieran for money she was received watching over him, and is shown to be very irresponsible.
It is later revealed that Tom witnessed his family's deaths, and is implied to have been traumatized, being a four-year-old boy who stayed with the bodies for several days before being discovered.
He later attempts to kill Emma when she rejects his advances, though is thrown off the balcony of the Whitten family mansion, resulting in his death.
Jeremy is the editor for Noah and Gustavo's comic book based on the second season's murder spree.
He is very pushy about getting this new book due to investing all his savings into the project, which quickly gets him on the bad side of the Lakewood gang, and is shown to be rude.
