The older brother of Hannah and Beth, whose disappearance a year prior set the game's dark events in motion. Josh invites a group of friends back to the mountain lodge on the anniversary of the tragedy to exact revenge for the cruel prank played on his sister. It is revealed that Josh, disguised as "The Psycho," was the one terrorizing his friends and setting up brutal psychological traps for them. Mental state: Due to untreated depression and severe trauma following his sisters' deaths, Josh is under the care of Dr. Hill. His actions stem from a deeply broken state of mind rather than pure evil. Relationships:

Family Hannah and Beth Washington: Josh's younger twin sisters. He loved them deeply and took their disappearance incredibly hard. His mental stability completely collapsed after their deaths, serving as the primary motive for his revenge against his friends.

Chris (Christopher): Josh's best friend. Josh considers him a brother and genuinely values ​​him; consequently, his "tests" for Chris (choosing between saving Ashley and Josh, or shooting himself versus Ashley) were a twisted attempt to bring Chris and Ashley closer together by pushing them toward a romantic relationship through shared stress. Chris is also the only one who shows genuine sympathy for Josh once the truth about the "Psycho" is revealed.

Sam (Samantha): A close friend of Josh and the best friend of his late sister, Hannah. There is a strong mutual attraction and chemistry between them. Josh values ​​Sam because she did not participate in the cruel prank against Hannah (she tried to stop it). Because of this, the "punishment" he devised for Sam was the least severe, though he still used her as part of his plan.

Ashley: Chris's love interest. Josh holds no strong personal animosity toward her, yet he uses her in his traps to "help" Chris demonstrate courage. Ashley is the most terrified by Josh’s pranks and subsequently harbors deep fear and distrust of him.

Mike (Michael): The primary instigator of the prank played on Hannah. Josh harbors a hidden but profound resentment toward him, holding Mike chiefly responsible for his sisters' deaths. When Mike and Chris tie Josh up in the shed, Mike treats him with the most brutality and later nearly kills him with a gun, believing him responsible for Jess's death.

Jessica: An active participant in the prank. Josh dislikes her for her mean-spirited nature and her role in the tragedy; however, she is removed from the main action on the mountain early on, so she is largely spared from the "Maniac's" direct pranks.

Emily: She was the one who lured Hannah into the room a year prior. Josh views her with open contempt, regarding her as selfish and calculating. Emily, for her part, never misses a chance to make snide remarks at Josh's expense.

Matt (Matthew): Participated in the prank (filming the whole thing), but Josh views him more as Emily’s henpecked follower than as a genuine threat or a primary enemy.

Dr. Hill: Josh’s psychiatrist. Their "relationship" plays out within Josh’s mind. Dr. Hill represents the remnants of the character's rational ego, attempting to appeal to his conscience, but as Josh’s condition deteriorates, the doctor transforms into a terrifying hallucination.
