The Smurfette Principle: The only female character that is a willing part of the Delphi cult in the present. However, the "Confidential" folder's papers Erica may find when she's helping the doctor make perfume may suggest otherwise.
Peter Mason
Portrayed by Brian F. Mulvey
The Chessmaster: Created the Delphi cult to control Alodie's power, and later Erica's.
Wolf in Sheep's Clothing: Married Alodie and raised Erica with the purpose of continuing with the Delphi rituals.
Hannah Kaye
Portrayed by Sasha Frost
Doomed by Canon: Will die at the hands of the Delphi cult no matter what the player does.
Establishing Character Moment: While Kristie is first shown as a Neat Freak and Tobi as a cold smoker, Hannah appears calmly playing the piano, and even teaches Erica a few notes so she can play with her.
Kill the Cutie: She's the one of the nicest characters Erica meets at Delphi House, and she's also the first to die.
Insane Equals Violent: Her tantrums appear to be the reason she's interned in Delphi House.
Near-Death Experience: If she's saved by Erica and Kristie after being experimented on by Dr. Ballard, her seizure becomes this. Only by choosing epinephrine you save her from dying.
Not So Above It All: Underneath her bluster, she's really just scared of dying.
Kristie
Portrayed by Elaine Fellows
Animal Motifs: She loves rabbits, and draws them often, along with deers, foxes and butterflies. However, bunnies are her favorites.
Break the Cutie: She loses her father and Hannah no matter what the player does, and becomes utterly broken if Tobi dies.
The Ingenue: Acts particularly childish and innocent, even writing Hannah a get-well soon card before her operation.
Mia Greene
Portrayed by Nakeba Buchanan
Being Tortured Makes You Evil: Had violent breakdowns prior to entering Delphi House, but it was the Delphi rituals and the torture suffered at the hands of the cult that made her into a murderer.
Serial Killer: Commited the saga of murders of those involved in the Delphi rituals.
Yandere: Was obsessed with Alodie during her stay in Delphi House. Her death is the reason she started commiting the murders.
