Fear Street trilogy on Netflix: That ending and post-credits scene explained – CNET

The Grifter: In 1904, The Grifter is shown in a quick flashback to be drowning a girl in a lake. Although, a newspaper clipping indicates The Grifter’s favored murder method has something to do with the alliteration: “Grifter Guts Girls.”
The names written on the wall include Cyrus Miller (the pastor), William “Billy” Barker, Ruby Lane (Nurse Lane’s daughter), Isaac Milton and Harry Rooker (The Milkman).
In Part Two: 1978, Alice (Cindy’s former friend) and Cindy (Ziggy’s sister) find a wall carved with the names of all the Shadyside Killers underneath Sarah Fier’s house. Alice realizes that anyone whose name is written into the rock becomes possessed. Nurse Lane’s daughter Ruby Lane is one of the possessed and attacks Simon in 1994. This is why Nurse Lane tries to kill Tommy Slater, knowing he too will turn into a killer, after she sees his name written on the wall.

Warning: Spoilers ahead

Is Sarah Fier evil?

He writes the sacrifice’s name on the stone wall in the secret passage beneath his house and the Devil possesses them. Sarah points out this sees the murders of even more people, as the Devil heads out on a killing spree.
Humpty Dumpty Killer: A newspaper clipping reveals that in 1935, the Humpty Dumpty Killer “strikes again.” The details aren’t clear, except that the killer’s victims likely can’t be put back together again.

When Deena reunites Sarah Fier’s hand with the rest of her skeleton, she flashes back in time to 1666, where she witnesses the truth behind the Shadyside curse.

One of the first things established in Part One: 1994 is the feud between Ohio’s (fictional) rich and poor rival towns. Shadyside is known as the murder capital of the United States, while Sunnyvale is considered one of the richest and safest cities in the country. “Bad things always happen to Shadysiders,” Sadie Sink’s Ziggy says.
It’s been a tough, wild ride, but finally we know the truth behind the Shadyside Killers in Netflix’s Fear Street. The trilogy of films took us from 1994, back to 1978 and finally 1666, exploring why possessed serial killers were brutally murdering the residents of Shadyside, Ohio. It all had something to do with Sarah Fier, a witch who cursed the town to centuries of misfortune, while on the other side of the tracks, the town of Sunnyvale thrived.
The villagers hang Sarah, but not before she promises to reveal the truth about the Goodes. “The truth shall be your curse,” she tells Solomon. “I will shadow you for eternity. And everything you take and everyone you harm, you will feel the grip of my hand. I will follow you forever. I will never let you go.”

What does the feud between Sunnyvale and Shadyside mean?

This is why when Deena completes Sarah’s skeleton, she sees exactly what happened in 1666. However, there’s a consequence: Anyone who touches Sarah’s bones becomes a target of the Shadyside Killers.

What’s the connection? Why is one better than the other?

Are Sunnyvale and Shadyside real cities?

Farmer of Death: A note on Josh’s detective wall says “Farmer of Death — 1890.” We don’t learn more than that.

What are the names written on the stone wall?

Josh’s research comes in handy.

Who are the different killers?

Camp Nightwing Killer: This is Tommy Slater, whose axe-wielding origins we see in Part Two: 1978. “Group of campers, brutal massacre. There was one Shadyside survivor, C. Berman,” his newspaper clipping reads.
Maya Hawke’s Heather falls victim to a possessed Ryan Torres.
The reporter goes on to say that the Goode family “maintains they had no knowledge of Sheriff Goode’s horrifying secret.”

A real Shadyside, Ohio exists, but thankfully the violent history depicted in the films is fictional (the movies are based on R.L. Stine’s popular Fear Street book series after all). Several Sunnyvales exist as well, but they’re scattered across the US and don’t border Shadyside.
Billy Barker: Aka the creepy mask-wearing child. Barker bludgeons his sleeping brother in bed with a baseball bat in 1922. According to another newspaper clipping, Barker died in unknown circumstances following the murder. Like Ruby Lane, he too probably tried to (unsuccessfully) end the curse by killing himself.

That post-credits scene

The Milkman: In the 1950s, Harry Rooker was a milkman before he became one of the Shadyside Killers. The Milkman went on a murder rampage, killing his customers — all of them housewives — with a switchblade.
As for those hands? We can only speculate who stole the book at this point, but maybe the Goode family isn’t done with the Devil just yet.
Ruby Lane: Nurse Lane’s daughter, a 16-year-old Shadyside high schooler who murdered her boyfriend and six more with a razor in 1965. You can tell she’s coming when you hear her singing You always hurt the one you love, by the Mills Brothers. Ruby’s wrists are slashed — a sign of her attempt at killing herself and (unsuccessfully) ending the curse.
This is great news for fans who want more from the Fear Street world (we don’t have any news on follow-up films or TV series just yet).
