Biography[]
Born to Scandinavian doctor Finn Pederson, Cecilia Pederson utilized her insight from her father's career to launch The Pederson Project, a large-scale scam operation targeting the desperate and terminally ill by claiming to provide experimental, highly effective Norwegian cancer treatment like her father does, given how doctors have pressured governments to not authorize his experiments, making him a recluse.
Cecilia successfully continued the illegal activities for eight years before being contacted by John Kramer, a brain cancer patient referred by accomplice Henry Kessler. Not knowing that John is the Jigsaw serial killer, she proceeds with arranging a meeting. The following week, Cecilia meets with John at her facility in Mexico City. Following an apparently successful surgery on John's brain tumor, John departs with a new but short-lived lease on life. However, John quickly discovers that the operation was a scam, and, outraged, vows revenge.
While at her mansion, Cecilia is attacked and drugged by John and his apprentice Amanda Young. Cecilia awakens in the facility along with co-conspirators Mateo, Valentina and Gabriela. John provides an overview of the "game" before he and Amanda exit to the next room. Cecilia's repeated attempts throughout at bargaining and appealing to John's humanity have no affect.
Cecilia provides verbal support for Valentina during her game before witnessing her decapitation upon failure. While she believes her kidnappers aren't looking, she drops her concerning façade of distraught and methodically retrieves her phone by disemboweling Valentina's corpse to use her entrails as a rope. Cecilia alerts Parker Sears, lover and accomplice, of the situation before a hidden Amanda activates her shock collar, confiscating her phone.
Cecilia resumes feigning concern as she supports Mateo in his game until his demise. Cecilia then watches Gabriela survive her game albeit severely injured. Parker forces John and Amanda into the game room at gunpoint to free Cecilia. Upon release, she slaps Amanda in the face and tells her that she wanted to do that since the moment she met her. They have Amanda shackled and John placed in her collar. Cecilia lets the mask fall off, crushing a defenseless Gabriela's neck under her shoe and killing her, gleefully putting her cold, calculating nature on display.
Realizing that Carlos, a local boy that John had befriended, is playing outside, Cecilia manipulates Carlos into the game room and forces him to endure her intended trap that she describes as "blood-boarding". Tiring of watching the torture, the partners in crime enter the next room to retrieve their scam money but activate a tripwire that disables John and Carlos' trap and locks Cecilia and Parker within as poison gas surrounds them. With a small hole in a wall as a sole evasion of inhalation, Cecilia murders Parker and shoves her head through the hole, forlorn as John, Amanda and Carlos leave with the money, without telling her how to escape. With that, Cecilia is abandoned by them and left for dead.
