Switch (2012) Timeline Explained – Every Event in Order

Sophie was arrested because police found a headless body in the locked room of the apartment she was staying in. The victim was Thomas Huygens, Bénédicte Serteaux's boyfriend. Investigators believed Sophie was actually Bénédicte because a passport bearing Sophie's photo in Bénédicte's name was found, the Switch website had vanished, and neighbors identified her as the apartment's owner. Sophie had no way to prove her true identity initially.

Claire Marras, who helped create the Switch website, erased its digital footprint as part of Bénédicte's scheme. Claire was recruited by Bénédicte to build the platform and then destroy all evidence of it, making it impossible for police to trace Sophie's travel arrangements or prove she had used the legitimate swap service.

Bénédicte Serteaux killed Thomas Huygens. She beheaded him and locked the body in her apartment as part of a elaborate revenge plot. This murder was designed to frame whoever arrived at the apartment, Sophie's arrival conveniently provided the perfect suspect for the crime.

Sophie and Thomas Huygens were half-siblings, sharing the same biological father. Their father had lived in Paris and sold his sperm to support his family, unknowingly producing both children. This hidden family connection was discovered through DNA analysis and became central to understanding Bénédicte's motive.

Bénédicte discovered through her work at a laboratory that she shared a biological father with Sophie and Thomas. Traumatized by a miserable childhood, she wanted to destroy anyone who had the happiness she was denied. Since Sophie was a stranger to her but shared her father's genes, Sophie became the perfect target for Bénédicte's revenge scheme, which involved framing her for murder and assuming her identity.

Sophie asked Marianne to search her Montreal home for proof of identity. When Marianne entered the house, she discovered Thomas Huygens's severed head on Sophie's bed surrounded by blood and candles. As she tried to flee, a woman dressed in black, presumably Bénédicte, attacked and mortally wounded her, then set the house on fire.

The woman who arrived in Montreal from Paris wearing a headscarf and sunglasses was almost certainly Bénédicte in disguise. She traveled to Sophie's address and picked up a package, then posed as Sophie when questioned by investigators. This was part of her elaborate identity theft scheme to assume Sophie's life while framing her for the murder in Paris.

Yes, Kourosh was entangled with Bénédicte's schemes. When Sophie fled to him for help, he initially appeared sympathetic, but his true allegiance was revealed.

Bénédicte underwent cosmetic surgery to alter her appearance and resemble Sophie. This transformation was part of her elaborate plan to steal Sophie's identity. She used her position at a laboratory to access resources and fund the procedure, allowing her to impersonate Sophie convincingly enough to deceive her own mother and neighbors.

Both Sophie and Bénédicte shared the rare blood type because they had the same biological father. Their father had sold his sperm, making both women his biological daughters. This rare blood type match initially convinced police that Sophie was indeed Bénédicte, strengthening the case against her.

Bénédicte created the Switch home swap website and recruited Claire Marras as the technical architect. She then manipulated the system so that Sophie would be matched with her Paris apartment, the exact location where she had hidden Thomas's body. After Sophie arrived, Claire erased all digital traces of the website, ensuring Sophie's travel records would be impossible to verify.
