By the end of the eighth and final episode of the first season of Furious , billionaire Jay Easton (Peter McRobbie) is dead, Catherine (Lola Petticrew) is in prison, and Alice (Emmy Rossum) has secured a full-time position working under Nora (Quincy Tyler Bernstine) in the Bureau's basement-level sex crimes unit.

But not all was as simple as it seemed, as creator Elizabeth Meriwether's cat-and-mouse thriller still had a final twist up its sleeve.

Over the course of its first seven episodes, Furious tracked NYPD homicide detective-turned-probationary FBI duty agent Alice's hunt for serial killer Catherine, a sex trafficking survivor targeting wealthy, high-profile men involved in her past abuse.

Along the way, we learned Catherine's primary motive was not simply retributive justice, but rather a desire to uncover the truth about the mysterious circumstances surrounding the death of her best friend and first love Isabel (Larissa Campos) at the Easton estate over a decade earlier.

With the help of Nora's corrupt boss Ed (Danny McCarthy), Jay covered up Isabel's death to shield his involvement in a prolific child sexual abuse and trafficking ring.

Catherine is convinced Jay himself killed Isabel, but due to the severe memory distortion she suffers from as a result of her trauma, she can't fully remember what happened on that fateful night.

After Catherine's fiancé Alden (Steve Way) gave Alice's former partner Danny (Scoot McNairy) a flash drive containing years of incriminating evidence against Jay and his associates, it was revealed there was a folder containing an illicit video of a then-14-year-old Alice being abused by one of the men within Jay's network.

Episode 7 then ended with Alice tracking down Catherine and, instead of arresting her, manipulating her into driving out to Jay's Connecticut estate while Alice followed closely behind in order to orchestrate an incident that would allow Alice to search Jay's compound and arrest him without handing over the flash drive.

Who killed Isabel? Lola Petticrew as Catherine in the Furious finale. —Sarah Shatz—Disney Although Episode 7 led us to believe Jay's daughter Emma (Hope Davis) was going to be exposed as the person who had killed Isabel, Furious had a much more tragic reveal on the way.

While Emma was anything but innocent considering she spent years procuring underage girls for her father and destroyed evidence of his crimes to protect their family, in the finale, she helped Catherine remember that Catherine herself was the one who ultimately injected Isabel with the drugs that killed her.
