chunk: A chase ensues from Graham's apartment to the elevator where Hedy chokes Allie unconscious and drags her towards the furnace. When Hedy finds Allie missing, she grabs a hook from a closet and screams for Allie to come out. Lured into thinking Allie is hiding in another closet, Hedy lashes out at a mirror inside. She is then stabbed in the back by Allie and they struggle briefly before Allie strikes one last blow. She then watches in horror and sadness as Hedy dies.
  In an epilogue, Allie narrates that she has finally moved on. She forgives Hedy for killing Sam, and keeps trying to forgive herself for Hedy. She states that Hedy's survivor's guilt was her downfall. Allie states that she knows what happens to those people. The final shot is a photo of her and Hedy's faces superimposed as one.
