Linden Ashby as Sherrif Stilinski -Human-
Sheriff Stilinski is Stiles’s father and the sheriff of Beacon Hills. Like Stiles, his first name is unknown. Stilinski is close to Scott and Scott’s mother, Melissa. He is an intelligent and dedicated officer, although his ability to do his job is hampered by his initial unawareness of the supernatural forces behind many of the crimes in Beacon Hills. Stilinski and Stiles are mutually supportive and protective of one another, in part because of the death of Stiles’ mother, Claudia, some years before the series timeline. In Season 1, Stilinski links the murders committed by the Alpha werewolf to the Hale House fire. He discovers an accomplice in the arson, Adrian Harris, who gave him the lead to the culprit, a pendant. In the Season 1 finale, he finds the body of Kate Argent with the necklace, linking her to the crimes. In Season 2, he is again working on a killing spree. He is put on temporary leave because of Stiles’ behavior throughout the season, straining his relationship with his son. With Stiles’ help, he finds out the victims were a part of the Beacon Hills High 2006 swim team. He is held hostage at the Sheriff’s station with Melissa and their sons by Matt, when they uncover evidence convicting Matt. After the events are resolved, he is reinstated as Sheriff.
In Season 3, Stilinski again has a murder spree on his hands, this time committed by the Darach. Stiles is reluctant to let his father in on the supernatural business out of fear he could be killed. Eventually in the episode “The Girl Who Knew Too Much”, he attempts to tell Stilinski the truth using previous seemingly inexplicable incidents, but Stilinski says he doesn’t know what he’s seen, harshly trying to end the argument. Stiles talks back, saying, “Mom would’ve believed me.” Stilinski later uncovers information on a hunch about the supernatural and discovers Jennifer Blake about to kill Lydia, witnesses Jennifer removing her glamour talent to reveal her actual face, the Darach, and Scott in his werewolf form. Jennifer abducts him for the guardians’ sacrifice. He is held in the Nemeton along with Melissa McCall and Chris Argent. He is now brought up with the supernatural. In “Alpha Pact”, he relays a story eight years ago; when Claudia was on her deathbed. He was helping a girl who was caught in a car accident. He was holding the girl’s hand and her grip tightened. She’d comforted him saying if his wife was dying, he should leave and go be with her. Ultimately, he didn’t waiting for paramedics to arrive instead. Claudia had already passed away when he arrived and Stiles had been with her. If he’d believed in the supernatural, believed that the girl psychically knew that Claudia was dying, he would’ve been with his wife in her final moments. He and the parents are rescued by Allison and Isaac just as Jennifer is using the storm to bury them. Stiles arrives holding up the ceiling of the root cellar with an aluminum bat and is reunited with his son.
Finally brought into the supernatural circle of Beacon Hills, and subsequently closer to Stiles, Stilinski starts to search through old cases which he suspect could involve a supernatural creature, particularly the case of Malia Tate. He asks Scott to help him to find some clue in Malia’s house, but this proves unsuccessful. Later, Stiles admits to Scott this action was his last attempt to solve some case when he’s still the sheriff, since Rafael, Scott’s father is having Stilinski impeached for a “lack of resolution and ability to close cases”. However, with Scott and Stiles’ help in the following episode “More Bad than Good”, Malia Tate is found alive and he reunites her with her father and Stilinski closes the case in Rafael’s face. Stilinski temporarily puts his dislike of Rafael aside in “Riddled” when Rafael finds Stiles after he goes missing and shakes his hand in gratitude. Stilinski has been taking notes of Stiles’ growing symptoms and has him undergo a test for the same disease that killed Claudia. When he sees a brain scan similar to his wife’s, he is visibly shaken. However, later, Scott reveals to Stilinski Stiles is possessed by the dark trickster, the Nogitsune. Displaying belief in the supernatural, Stilinski clues in on the fact that the Kitsune is a trickster, he realizes that Stiles’ MRI results are fake. They are virtually similar to his wife’s results, courtesy of the Void kitsune: he relates to his time in the army; he was taught that to defeat a foe, “you take away their hope”. Rafael helps to talk Stilinski out of the impeachment case, saving his career and admits he only needed a reason to stay in Beacon Hills so he could make things up with Scott. Stilinski attempts to give Rafael some sound advice, that he reveals to Scott why he left. In “Insatiable”, when he sees the Nogitsune has been exorcised from his son, he gives Stiles a tight hug. In “The Divine Move”, the Sheriff and his new assistant Deputy Parrish are attacked by the Oni, they put up a good fight, but are overpowered and dying but are saved when the Oni are destroyed. In Season 4, Stilinski learns of the Dead Pool, the hit list of supernaturals, from Scott and Stiles; he immediately starts to help, having the hit list run through recognition to find the intended targets. Stilinski and Stiles are having money problems, trying to pay for the MRI test and the “visit” to Eichen House which are both long overdue. Stiles is tempted to use the Dead Pool money Scott found to help solve the problems. Later on however, because Stiles was almost murdered by Brunski, their Eichen House bill is dropped as a gesture of apology. In the Season 4 finale, “Smoke and Mirrosr”, Stilinski saves Lydia and Mason from a Berserker using a Claymore mine, destroying the Berserker.
