WARNING: The following contains spoilers for Fear Street Part 1: 1994 and Fear Street Part 2: 1978, now streaming on Netflix.

Fear Street Part 1: 1994 focuses on the attempts of Deena trying to save her girlfriend, brother and friends from the Shadyside Killers, yet she is barely successful, with her friends -- Simon and Kate -- dying and girlfriend, Sam, becoming possessed. Fear Street Part 2: 1978 looks to the past to provide Deena and her brother, Josh, clues into how to save Sam and end the curse once and for all. At the center of their investigation is C. Berman, the only other person to survive seeing the witch, and her experiences at Camp Nightwing possibly are the key to unraveling the entire mystery of Sarah Fier's curse.

Who Is C. Berman in the Fear Street Trilogy?

In Fear Street Part 1: 1994, C. Berman is an enigmatic survivor of the 1978 Camp Nightwing massacre. In first movie, the teens learn she saw the witch and survived, so Deena and Josh try to contact her, but she does not pick up the phone initially. However, after the carnage is seemingly over, C. Berman calls Deena to let her know that the horror was just beginning.

The beginning of Fear Street Part 2: 1978 shows that C. Berman lives in a house filled with clocks, which remind her to do basic tasks, like eat, check the locks and feed her dog. When she does not respond when Deena and Josh arrive, they break into her house to try to get her to reveal more information to end the curse, and C. Berman reluctantly agrees to tell them about the 1978 massacre.

In Part 2, viewers learn that C. Berman actually is Christine "Ziggy" Berman, a Shadyside camper at Camp Nightwing and the younger sister of Cindy Berman, one of the camp's counselors. Since Ziggy's real first name is not revealed until the end, her sister serves as a red herring for C. Berman's identity. Fear Street Part 2: 1978 focuses on C. Berman's recollection of the massacre she survived, revealing who she is and how she is connected to the Shadyside curse.

From the beginning of the flashbacks, Ziggy is falsely connected with Sarah Fier, and she genuinely believes in the curse. At camp, she is bullied by the Sunnyvale campers, who claim she is possessed by the witch. They hang her by her wrists from the tree where Sarah Fier allegedly was hanged, and their ringleader, Sheila, tries to burn Ziggy. The Sunnyvale campers are also not punished, showing again how Sunnyvalers are treated better at the expense of the citizens of Shadyside.

Ziggy is also the last person to see Nurse Mary Lane before she tries to kill Tommy Slater, Cindy' boyfriend and the curse's next killer. Ziggy tries to tell Cindy about how upset Mary is and the curse, but Cindy is unwilling to listen until after the massacre begins. At first, Ziggy is unaware of the massacre, focusing on revenge and her own budding romance with Nick Goode; however, during Ziggy and Nick's first kiss, they hear Tommy's killing spree, and he eventually sets his sights on Ziggy, yet Cindy kills him, giving them some time to reconcile before he returns from the dead.

With Cindy and Alice learning more about the curse before reuniting with Ziggy, they think they know how to end the curse by returning the witch's severed hand to the rest of her buried remains. However, Ziggy gets a nosebleed, and her blood gets on the hand, giving her vision of Sarah Fier, similar to Sam's visions in the first film. The curse then resurrects the Shadyside Killers, including Tommy, and he kills Alice before pursuing the sisters, who run to the hanging tree. Sadly, Sarah Fier's body is not there, and with nowhere to go, the killers murder both sisters, but Nick resuscitates Ziggy, which is how C. Berman survives the massacre.

While C. Berman feels hopeless, she provides Deena and Josh the information they need to potentially end the curse. Since they found Sarah Fier's remains in the first film, they need to retrieve the hand from the hanging tree, which is now at the center of the Shadyside Mall. When Deena reunites the hand with the body, she seemingly enters into a flashback where she will see the events of 1666 through Sarah Fier's eyes, effectively setting up the trilogy's final film, and this is all thanks to C. Berman.

Directed and co-written by Leigh Janiak, the Fear Street trilogy stars Sadie Sink, Kiana Madeira, Olivia Welch, Benjamin Flores Jr., Darrell Britt-Gibson, Ashley Zukerman, Fred Hechinger, Julia Rehwald, Jeremy Ford and Gillian Jacobs. Part One: 1994 and Part Two: 1978 are available now on Netflix, followed by Part Three: 1666 on July 16.
