chunk: This is witnessed by MacRae, who had snuck inside Dr. Channard's house to investigate Kirsty's claims. He returns to Kirsty to tell her, and the two decide to return to Dr. Channard's house, so Kirsty can attempt to save her father who she believes is still trapped in Hell. They also decide to bring a young patient named Tiffany (Imogen Boorman), whom Kirsty has befriended. Tiffany, who hasn't spoken for years, demonstrates an amazing aptitude for puzzles.
  Meanwhile, Dr. Channard, seduced by Julia, has surreptitiously brought more mentally ill patients to his home for her to feed on. When Kirsty and the others arrive at Channard's home, MacRae heads to the attic, and discovers the grisly remains of their bodies. Julia, her skin almost completely regenerated, appears and kills him, consuming his essence and completing her skin regeneration. Kirsty hears the commotion and rushes up to the attic, and walks in on the scene. Enraged, she attacks Julia, but is knocked unconscious.
