Jake Fitzgerald is the obnoxious basketball player who attends George Washington High School. He is best friends with Will Belmont, Tyler O'Neill and Brett Shimura. Jake is the boyfriend of Brooke Maddox.
Like numerous clinically-diagnosed mentally ill psychopaths, Jake wears a metaphorical mask of normalcy throughout the series, establishing himself as a cool-headed schemer and gaining the trust of those around him, despite his rather untrustworthy physical appearance. Even with this mask, Jake's psychopathic tendencies tend to seep through and become apparent to the viewer, particularly in the Season 1.
He could torture people to the fullest extent without killing them, like he did with Seth Branson before finally finishing him off. Jake also displays narcissistic tendencies, his most obvious ones being his obsessive desire for power and sense of entitlement, as well as manipulating Emma Duval to achieve his goals. It is not until Jake gains control of the situation that fully shows his true colors, becoming arrogant and short-tempered with the Lakewood Six after usurping power from Piper Shaw, who is now deceased.
Jake also was depicted as laughing excessively and in a deranged manner shortly after accidentally revealing himself to Emma and Audrey Jensen, suggesting that Jake was also insane and suffered from hysteria. It is this impulsive behavior that leads to his downfall, as he uses his acting skills to become an omnipotent killer, unaware of the life inside of himself.
