About me:
He was born in 1995 to Noah and Claudia Stilinski and grew up in Beacon Hills, California. As a child, he was unable to properly say his birth name, Mieczysław (a Polish male given name pronounced mee-chee-swahv); the closest he could get to a correct pronunciation was "Mischief" which became a nickname that his mother began calling him as a result of his naturally mischievous nature.
As a young child, Stiles' mother Claudia was stricken with frontotemporal dementia. During the time she endured this illness, Claudia suffered such horrifying delusions that she was under the impression that Stiles was trying to kill her despite the fact that he was really just an anxious child worried about his mother. According to the repressed memory Stiles experienced in a flashback due to reading The Dread Doctors novel by Gabriel Valack, Claudia even violently attacked Stiles on at least one occasion as a result of her dementia, which caused her to develop a very strong case of paranoia and dissociation.
Claudia ultimately died while being treated in the hospital, on an afternoon when the young Stiles was visiting with her; he unfortunately had to endure the traumatic experience alone due to his father being caught up dealing with a car accident case, as Noah ultimately decided to stay late to comfort a woman who was dying as a result of the crash.
At Claudia's funeral, Stiles' father, Noah, saw how badly Stiles was mourning his mother's death and assured him that he still had him, and their mutual loss caused Stiles to become incredibly close to Noah to help each other get through Claudia's death together. Afterward, Stiles began to experience anxiety attacks and bouts of sleepwalking, though he eventually grew out of it for a time. He also seemed to be aware of his father's affinity for whiskey, which occasionally went too far, to the point where Noah was asked by his fellow employees to cut down on his drinking. This was evidenced by when Stiles defended his father against Special Agent Rafael McCall's insinuations that Stilinski had relapsed. When he was old enough to start driving, his father gave him his Jeep, which had belonged to his mother, and which she had wanted him to have once he was old enough to drive it. The first time he took it out for a drive, he went into a ditch, and his father handed him his first roll of duct tape in order to fix it, a method of DIY-repairs that Stiles maintains to this day.
