Cursing Sabrina[]

The Weird Sisters curse Sabrina
The Weird Sisters appear in the woods after hearing Sabrina Spellman summon a familiar. They know that she’s going through with her Dark Baptism and transferring to the Academy of Unseen Arts. However, as far as they’re concerned, Sabrina being the half-breed that she is, is not welcome and they seek to chase her away. Prudence warns Sabrina to stay away from the academy as she wouldn’t want what happened to her mother and father to happen to her. Dorcas and Agatha add that it would be tragic should the accident that took their lives also befalls Sabrina. The Weird Sisters then place a curse on Sabrina. Almost instantly, Sabrina’s nose starts to bleed.[1]
Torturing Mortal Boys[]

The Weird Sisters agree to help Sabrina
After learning the names of the boys who harassed her friend, Susie, Sabrina summons the Weird Sisters to ask if they'll help her get revenge on four mortal boys. They surmise that Sabrina summoned them to remove the curse they had previously placed on her, but they would only do so if she pledged not to attend the academy. Sabrina explains that the curse has already been reversed, but she is still willing to strike a deal. If they help her teach the boys a lesson, then she won't attend the academy. Prudence, Dorcas, and Agatha come to an agreement. However, Sabrina strikes this deal with her fingers crossed behind her back.

Sabrina and the Weird Sisters invite the boys to the mines
That night, Sabrina and the Weird Sisters approach Carl, Billy, Ed, and Seth outside a convenience store and coax the boys into joining them for a party in the Greendale Mines. While they recognize Sabrina from Baxter High, they aske where her friends attend, presumably Riverdale High School, but Prudence simply states that it's a special school. The girls take the boys into the mines, what some call "The Devil's Doorway." The mines run so deep that one shaft takes you down to Hell.

Prudence, Agatha, and Dorcas scare off the boys
Both the boys and girls quickly undress. The Weird Sisters and Sabrina have cast an illusion spell on the boys to trick them into hooking up with themselves. The illusion fades once the flash from Sabrina's camera goes off. Sabrina tells them that the pictures will be posted all over school if they hit Susie or any girl ever again. When Billy becomes aggressive, Prudence takes charge. She cuts off the lights, and she and her sisters transform, taking on a ghoulish appearance, consisting of gray-green skin, glowing eyes, and black-rimmed teeth, causing the boys to run in fear. Salem watches from outside as the boys come rushing out.

Prudence, Agatha, and Dorcas put a spell on the boys to make them impotent
Sabrina finds a steel cage with four birds inside sitting on the ground. Prudence, Dorcas, and Agatha took the boys' boyhood. Until Sabrina releases the birds, Seth, Ed, Billy, and Carl won't be rising to any occasion. Dorcas believes that a few weeks of impotence might teach them better manners. Prudence then states that Sabrina might be more suited for the academy than they initially thought. They know Sabrina lied, but they helped her anyways because they enjoy tormenting mortal boys. Sabrina doesn't want to leave with her friends still having to deal with the boys. Prudence questions why leave at all if she cares about her friends. Sabrina explains that with the visit from Father Blackwood, she wasn't sure she had a choice in the matter, which comes as a surprise to the Weird Sisters. Prudence tells Sabrina that signing her name into the Book of the Beast is an even exchange. She gives up her freedom in exchange for power. However, Sabrina wants both.

Sabrina's Dark Baptism
The Weird Sisters attend Sabrina's Dark Baptism. Sabrina is disrobed as part of the ceremony. Sabrina kneels. Father Blackwood smears blood over her forehead and read Sabrina her rights and demands her loyalty. However, when it comes time to sign the Dark Lord’s Book of the Beast with her blood, Sabrina backs out and takes off running. Father Blackwood orders the coven to get her. The coven follow Sabrina back home and demand her signature, but she refuses. When Father Blackwood orders Dorcas, Prudence, and Agatha to take Sabrina, Ambrose informs them that a circle of protection rings the house, and no witch save for a Spellman may cross it. Any unwelcome witch that tries shall burn. With that, the coven retreats.[2]

The Weird Sisters attend Sabrina’s Trial
The Weird Sisters attend Sabrina’s Trial. She is being sued for breaking her promise to sign the Book of the Beast. Sabrina hires the mortal Daniel Webster as her lawyer. During the trial it’s revealed by Zelda that Sabrina’s father, Edward Spellman, signed Sabrina’s name in the Book of the Beast when she was three days old. However, Hilda reveals on the last day of the trial that Sabrina’s mother, Diana Spellman, baptized her in the Holy Mother Church of Greendale, much to the shock of the entire coven. After a short break, Father Blackwood announces that due to conflicting contracts, the Hellbound Court of Greendale decrees that Sabrina shall retain her mortal life on the condition that she also attend the Academy of Unseen Arts, as well as weekly Black Mass. Sabrina accepts the court’s decision.[3]
The Harrowing[]

The Weird Sisters have lunch with Sabrina
On Sabrina’s first day at the Academy of Unseen Arts, Faustus Blackwood takes her to choir class where his wife, Constance Blackwood, is teaching. Lady Blackwood asks Sabrina to sing a few verses for her. After she does, Lady Blackwood comments that Prudence finally has some competition. Later, the Weird Sisters join Sabrina and Nicholas Scratch at lunch. Prudence gives Sabrina a hard time for having a mortal boyfriend and running from her Dark Baptism. Nick offers to walk Sabrina to her next class and Sabrina accepts.

The Weird Sisters harrow Sabrina
The Weird Sisters put Sabrina in the Witch's cell as part of the Harrowing, a witch tradition. Sabrina has to endure the same punishment as the Greendale Thirteen. Thirteen made it to the noose, but many more perished in the cell. The witches weren't given any water, sunlight, or food. Most of them went mad and cut their own throats and still haunt the academy. Sabrina has to survive the night in the cell. The next morning, the Weird Sisters open the door and find Sabrina shaking. She turns around smiling at them. She introduces them to Salem, who snuck into the cell in the middle of the night to protect and comfort her.
After a shower and a phone call with Harvey, Sabrina discovers that Salem is missing. She asks the Weird Sisters where they've hidden him and gets into an altercation with Prudence. Father Blackwood interrupts the fight and tells Sabrina to come to his office.

The Weird Sisters lead Sabrina into a field
Dorcas, Prudence, and Agatha pull Sabrina from her bed once more and lead her down the same path as the Greendale Thirteen, who survived torture and imprisonment only to be walked to the noose. They kept their eyes straight ahead, fixed on the path. Mortals surrounded them on either side, and if any witch lifted their eyes to meet a human's gaze, they were stoned to death on the spot. The four girls arrive in a field, under a tree. Sabrina is to do what the original 13 did. She must stand in cold night without shoes or rest. Prudence warns her from turning around no matter the noises she hears. She must remain facing the tree until dawn.

The Weird Sisters are hanged
The Weird Sisters take Sabrina to the tree where the Greendale Thirteen were hanged. Prudence ask if Sabrina has any last words. Sabrina remarks that the 13 couldn't possibly have imagined a place like the academy. A school where witches would be safe. Even if they could, they'd never believe that the women inside its walls would turn on one another. Which is why Sabrina says that the academy tradition of harrowing ends now. However, Prudence is intent on hanging Sabrina. As she puts the noose around Sabrina's neck and pulls on the rope, Quentin and the other victims of the Harrowing arrive and hang the Weird Sisters. Sabrina tells them that there will no longer be any harrowing before having the children release the sisters. Sabrina then warns Prudence against speaking on her parents moving forward.[4]

The Weird Sisters in Sabrina’s Nightmare
inside Sabrina's dream, her witch life and mortal life are fused together. The Weird Sisters are cheerleaders who mock her, and Nick is a football player who flirts with her. Harvey proposes to Sabrina. On the day of the wedding, Sabrina tells Harvey that she's a witch, and he starts to choke her before shoving her into an Iron Maiden torture device.
The Weird Sisters also appear in Zelda's dream. Zelda is reading to the Children of Night about the False God and Adam and Eve. They tell her that the Dark Lord will be coming to dinner at her house tonight. Once a year, he assumes the shape of man and visits his most devout disciples. This year it's Hilda and Zelda.[5]
Feasts of Feast[]

Prudence is participating in the Feast of Feasts
Dorcas and Agatha learn that Prudence has been chosen to participate in the Feast of Feasts. Sabrina questions how she can be so happy that she may or may not be sacrificed. Prudence explains that there is no greater honor. Dorcas and Agatha add that it would be the first time that an orphan would be Queen. Later, at the selection ceremony, Prudence is chosen as Queen of the Feast. That night at the Spellman mortuary, Dorcas, Prudence, Agatha, Ambrose, Luke, and Nick have an orgy in the attic. Nick invites Sabrina to join them but Sabrina rejects the offer and leaves.

Sabrina, Madame Satan and the Weird Sisters visit a Feast of Feast ex-Queen
Ms. Wardwell takes the Weird Sisters and Sabrina into the woods. They arrive at Dezmelda's home in the woods of Moon Valley. Sabrina asks why she ran from the Dark Lord. Dezmelda reveals she ran from her High Priest and that she was younger than they are when she participated in the Feast of Feasts. She fled into the woods because her High Priest tried to "initiate" her the night before the Feast. Prudence asks what this has to do with her. Sabrina tells her that it isn't the Dark Lord asking her to do this but Father Blackwood. That he is but a man and that he can have faults. Prudence tells Sabrina that Father Blackwood doesn't have an agenda and that he is like a father to her. Prudence wants to be queen and asks why Sabrina can't accept that.

The Weird Sisters want to kill Harvey
Suddenly, a gunshot goes off and Dezmelda tells them to leave. They find a dead familiar in the shape of a dear. They make a circle around the deer and use string to make a pentagram around it. They become invisible just as the Kinkles arrive at the site. Seeing that there isn't a dead deer, they continue to look. Prudence, upset by the kill, exclaims "Once a hunter, always a hunter." Sabrina tells her Harvey's not a hunter but Ms. Wardwell notes he certainly looks the part. Prudence agrees by stating his whole family is witch hunters. Agatha and Dorcas want to kill him for murdering the familiar. Sabrina insists that Harvey isn't a killer. Prudence asks how her faith in Harvey is any different than Prudence's faith in the Dark Lord.

Dorcas an Agatha are not Blackwood’s daughters
The Weird sisters attend a dinner at the Spellman house along with the Blackwoods. Sabrina brings out dessert in which Hilda has added a truth potion. After everyone has a slice, Sabrina tells Prudence that she hopes she enjoyed her last supper. Everyone around the table tells Prudence that they're going to miss her — except Lady Blackwood, who unintentionally reveals that she enchanted the box to choose Prudence as queen. She did it because the Weird Sisters are Father Blackwood's bastards and that makes them a threat to her children. Dorcas and Agatha ask if they are also his children, but they're not, only Prudence. Father Blackwood now must summon the coven and draw for another queen.

Agatha and Dorcas plot to kill Harvey and Tommy
The coven attends the Feast of Feasts ceremony, where Prudence sits upon the throne of skulls. Father Blackwood walks in and begins to tell the coven that there will not be a Feast of Feasts but another witch named Mildred steps up, slits her throat and falls before the altar. The coven look to Father Blackwood for permission and after a moment of suspense, he gives it to them, much to Sabrina's horror. The witches begin to attack the body and tear it apart as they eat. After the Feast of Feasts ceremony, Prudence finds her sisters huddled together. She asks what they're doing and they say they are praying for her. Prudence leaves and Dorcas asks if they should've invited her. Agatha says no as she holds up a doll that looks like Tommy Kinkle. Dorcas holds one that looks like Harvey. The two of them pick up large rocks and smash them down on top of the dolls.[6]
Killing the Kinkle Boys[]
At the Academy of Unseen Arts, Nick asks Dorcas and Agatha if they've seen Sabrina. They tell him about the tragedy at the mines and how there's going to a funeral but that the mortals are burying an empty casket. Prudence overhears them talking to Nick and becomes suspicious of their actions.

Dorcas tattles on Agatha
Sabrina and Prudence confront Dorcas and Agatha for killing mortals. Prudence reprimands them for acting without her permission. Sabrina says that one of them is going to die so that Tommy can live. The sisters tell Sabrina that she doesn't have the guts to kill them. Prudence replies that she does. She asks who the mastermind was and Dorcas quickly sells out Agatha. Sabrina tells Prudence to bring them both to the woods. Nick asks if he can come along and watch. He asks what time and Sabrina tells him midnight in the clearing in the woods near the creek bed. Nick points out that she needs a Book of the Dead. Sabrina replies that she'll get one.

Dorcas reluctantly takes part in the resurrection spell
Dorcas, Prudence, Sabrina, Nick, and Agatha arrive at the clearing. They draw a pentagram and stand around it as they recite the spell. There are three stages to the Rite of Resurrection. First, they invoke the hounds. For the second stage, they open the door between worlds. For the third and final stage, they have to sacrifice Agatha. Sabrina then slits Agatha's throat. As she bleeds out onto the pentagram, they recite the incantation. Now they must wait thirteen minutes for Agatha's soul to leave her body. After that, they take her to the Spellman's graveyard and bury her in the Cain Pit. Suddenly, Agatha's hand shoots up through the dirt. Agatha then pulls herself out of the ground. Prudence tells her that actions have consequences and that what she did could've revealed their existence. Prudence says that she is never supposed to take such action without her permission again.[7]
Agatha's Illness[]

Dorcas notices that Agatha is sick
Dorcas, Agatha, and Prudence are praying when they notice that something is wrong with Agatha, who begins to throw up dirt. Hilda arrives at the Academy to look Agatha over. After failing to find Father Blackwood, they ask Ambrose for help. He tells them that he's no expert on the Cain pit but that Hilda is. Before long, she arrives at the academy and tells them that Agatha came back too soon. Hilda believes that Agatha has "too much earth in her system" and gives them instructions on how to take care of Agatha; they need to rebalance her elements. She tells them to prepare a tonic of fizzy water, which will give her water and air. And a dash of cayenne pepper for fire. Three times a day, for a week.

Prudence and Dorcas are trapped by Nick
Zelda is directing the choir at the Desecrated Church when Agatha walks in and collapses. Blackwood demands to know what's going on. Dorcas, Prudence, and Nick revealed that they killed Agatha to resurrect Tommy and how it's all Sabrina's fault. Blackwood goes to kill Tommy to restore the balance but Zelda tells him that she'll do it because Sabrina is her responsibility. After she leaves, Blackwood tells Dorcas and Prudence that they must end Tommy because he doesn't trust that Zelda will do it. Nick overhears this and follows them. Dorcas and Prudence go to Harvey's house but Nick stops them by driving stakes through their footprints. He explains that it's an old witch catching spell to prevent them from moving. Dorcas and Prudence cry out for help. Nick explains that they are going to stay put until the Spellman fix their mistake.
Sabrina leaves Harvey's house not long after. As Sabrina walks away from the house she, Prudence, Dorcas, and Nick hear the gunshot.[8]
Return of the Greendale Thirteen[]

The coven gathers in the Desecrated Church
The Church of Night gather at the Desecrated Church as a storm nears. Father Blackwood believes that the Dark Lord is angry with them but then Ambrose and Luke enter the church and reveal that the Greendale Thirteen have returned. Tomorrow night, during the witching hour, they will release their Crimson Avenger and it will go forth and kill every firstborn in Greendale. Father Blackwood tells them not to worry. They'll just hide at the academy as it's magically protected. He reminds everyone that they have to be at the academy at midnight or else they'll be left to fend for themselves.
At the academy, after defeating the Greendale Thirteen have been defeated, Sabrina struts into the school dressed like the Weird Sisters. She winks at Nick as the four of them pass by.[9]
A Séance at the Spellmans[]

Sabrina and the Weird Sisters perform a séance
Sabrina seeks the Weird Sisters' help with a séance. They agree to help, so Sabrina promises to leave her window unlocked. As planned, they arrive at Sabrina's as she brings her mother's white dress for the séance. Agatha summons Diana Spellman's spirit. Sabrina asks the spirit about the circumstances of her death. The spirit says 2321, which Sabrina recalls as being the flight number of the crashed plane that her parents died on. Sabrina wishes she could see her mother again. Diana's spirit channels herself into the dress. Sabrina is delighted to see her mother. Sabrina asks why she is Limbo. Diana warns Sabrina that it's not safe. Agatha senses an interference as several spirits enter the Spellman house through the fireplace. The spirits topple the Christmas tree. Zelda then enters and discovers Sabrina and the Weird Sisters conducting a séance. Diana disappears. Zelda is furious with Sabrina and orders the Weird Sisters to leave.[10]
