"It was me or the world, and my world felt complete. "
—Abbie Mills[src]

Grace Abigail Mills, who went by Abbie, was the co-protagonist for the first three season's of the television series, Sleepy Hollow. When first seen she was a lieutenant in the Sleepy Hollow sheriff's department, after season three, she had made the talked about transition to the FBI. She was also the Second Witness, foretold of in the book of Revelations to bear witness during the coming seven years of tribulations.


Early Life[]

Abbie had a troubled childhood. Both Abbie and her sister, Jenny Mills, dealt with instability at home as children. Their father was an alcoholic and their mother, Lori though loving, struggled with what was believed to be mental illness. Abbie and Jenny were very close, often locking themselves in their room to play with their dollhouse and escape their parents. Their father eventually left the family, and their mother was declared unfit and institutionalized, leaving Abbie and Jenny wards of the foster care system. Lori Mills would die while she was in the care of Tarrytown Psychiatric.

Abbie and Jenny then cycled through a few homes, during that time Abbie taught Jenny to pick locks, and they acquired a taste for criminal activity. Finally finding themselves in a place that Abbie felt was a good fit, then after school, they were sneaking beers in the woods when four white trees and a demon appeared before them. They both blacked out and neither were able to recall much of what happened during the four days they went missing. This was later revealed to be due local rancher from a search party, the girls were taken into police custody and callously interrogated. Jenny insisted on telling the truth about what they had seen even though Abbie warned against it, fearing that no one would believe her and that she would be removed from her foster home. Abbie lied and would not back up Jenny's story. Jenny was later put in a mental institution and the sisters remained estranged for nearly 13 years.

Abbie continued to struggle with what she saw in the woods, and her feelings of resentment and guilt toward her sister. By the time she was sixteen, she was pursuing a life of crime. After a botched attempt at robbing a pharmacy, she was taken into custody by Sheriff August Corbin, but instead of arresting her he offered her a chance. She accepted, and under Corbin's tutelage; graduated high school, went to college, joined the sheriff's department, rose to the rank of Lieutenant, and was accepted into an FBI entrance program at Quantico with a goal of becoming a criminal profiler.

Despite her success, Abbie was still marked by her tumultuous past. She never told Corbin about the demon she saw in the woods or that the experience still haunted her, making her doubt her own perceptions, feel out of place, and struggle in finding purpose. Some of Corbin's last words to her were to ask if her joining the FBI was really about her running away.

Season One[]

1x01 stills4

Lt. Mills

When first seen, Abbie Mills is having a conversation with her mentor and partner, Sheriff August Corbin. Abbie has set her sights on transferring to the FBI Academy in Quantico, Virginia. Sheriff Corbin wonders if Abbie has only considered this training position as an attempt to escape. This conversation is cut short when the two are told to respond to a disturbance at Fox Creek Stables. Once at the stables, Abbie realizes that something seems suspicious. Sheriff Corbin, while inspecting the barn, comes face to face, with the Headless Horseman, and after a few ineffectual shots at the Horseman, is killed by decapitation. Abbie is transfixed, as she sees her partner's head lying on the ground. As the Horseman makes his exit, Abbie is able to catch a glimpse of him. Back at the station, a man by the name of Ichabod Crane has been arrested and held as a suspect for Sheriff Corbin’s murder. Upon her return to the stations, Abbie says he is not the suspect she saw. After having a brief discussion, Abbie realizes that, Crane not only knows who the Headless Horseman is, but that he is responsible for cutting off his head.

Abbie, though reluctant, decides to defy orders, hoping that Crane can provide answers. Retracing his steps, Crane shows Abbie the cave in which he was resurrected. It is in this cave that Washington's Bible is retrieved, which seems to indicate that Abbie and Crane are the Two Witnesses, and according to the Bible, the two were brought together to witness seven years of tribulation. The Headless Horseman is the first horseman of the apocalypse; Death.

Throughout the season, Abbie struggles with the death of her mentor, her skepticism, her partnership with Crane, rebuilding her relationship with her sister, and accepting her role as a witness.

In Blood Moon, Abbie discusses the Headless Horseman with Captain Irving, who tells her that the other officers who witnessed the shootout recanted their statements about the Horseman. She asks about Andy Brooks, reminding him that something “snapped his head back like a Pez dispenser.” Captain Irving allows her to watch a video of Andy running his own head into the wall and killing himself while he was the only one in the cell. Abbie remains unconvinced and says Crane agrees with her.

In For the Triumph of Evil... Abbie finally comes to terms with her actions as a child, her betrayal of her sister. In a vision, Abbie confesses her sin, admits to what she saw that day in the woods, and confronts Ro'kenhronteys. She tells it she is not afraid anymore and won't desert her sister again. Immediately after, Ro'kenhronteys begins to harden into glass and Abbie shatters it with a chair.


The team assembles

She reunites with Jenny in The Lesser Key of Solomon. They manage to work together and Abbie learns that Corbin was Jenny's mentor, too. When Hessians begin the process of summoning Moloch, the men try to kill Abbie and Jenny jumps to her defense. When a Hessian grabs Jenny and threatens her, Abbie closes The Lesser Key of Solomon and throws the book into the demon pit, where it burns, thwarting them. That evening, Jenny sits handcuffed in an interrogation room. Abbie enters and un-cuffs her as Jenny questions her relationship with Crane. Abbie explains by quoting Revelations, "And I will give power to my two witnesses, and they will prophesy for 1,260 days". Trying to make amends for past mistakes, Abbie tells her that they lost everything that day in the forest, but that she now sees Jenny for who she really is and she’s proud of her. She offers Jenny a conservator-ship, where they might be able to get Jenny out of the psychiatric facility in less than six months. Abbie thinks that together they can find answers. Jenny tells her that Corbin said she’d be back when she was ready and looking for forgiveness.

In Sin Eater, Abbie is confronted with the idea that Crane would die, leaving her alone, just as she is learning to accept her role. Abbie and Jenny find him where he is being held by Masons and he tells her the plan to drink poison and kill himself, thus killing the Horseman as well. Abbie is horrified, "How can you be so calm about this? I'm terrified....Stay with me. Ichabod, please, stay with me. Please," she takes his hand and sits with him after he drinks the poison. He is then saved by the Sin Eater, who cleanses his blood of the Horseman's blood and Crane realizes he feels the Horseman no more. The Sin Eater announces that he has been sanctified. Abbie hugs Crane, and he admits that she was right, there is always another way.

In Sanctuary, Abbie reveals a nick in her armor while she and Crane investigate a disappearance at Fredricks Manor; as they enter the house and discover a bodyguard dead, they suspect his employer might still be alive, so Abbie calls for backup but can't get through, nor can she get a cell phone signal. She tries to head outside for better reception, but the doors and shutters all slam shut, preventing their exit, and Abbie snaps, "I am saying that haunted houses do not work for me!" Crane points out that they've survived worse threats than a haunted house, but Abbie is very unhappy. She then finds a much more amiable ghost than expected, the previous matron of the house, Grace Dixon. A vision leads Abbie to the to a bedroom where she witnesses Katrina Crane giving birth to a son. When Abbie finally reunites with Crane, she feels the news important enough to share. Crane is utterly gutted, his stunned response is a denial, he tells Abbie she must be mistaken because Katrina would have told him she was expecting. Abbie gently points out that maybe Katrina had no choice but to keep the baby a secret. Crane begged to know what happened to his son, but Abbie could not tell him. In the aftermath, Abbie receives information about Fredericks Manor. Of particular interest is the family tree of Grace Dixon. Abbie discovers she is a direct descendant; Abbie's ancestor brought Crane's son into the world.

Season Two[]

The arrival of a new Sheriff who is not party to the supernatural happenings, has Abbie walking on eggshells. She then discovers Sheriff Reyes had responded to domestic disturbance calls at Abbie's home when she was still a girl, and was directly responsible for Abbie's mother being committed to Tarrytown Psychiatric. As a gesture, Reyes allows Abbie access to her mother's files where she finds out that Lori wasn't mentally ill, but plagued by actual demons. After confronting a murderous demon at Tarrytown Psychiatric, a demon who had actually driven their mother to suicide, Abbie and Jenny have a moment with the spirit of their mother who reveals that she always knew Abbie was a Witness. She tells them their ancestor, Grace Dixon, had passed down a spell book that contains clues to a weapon that could destroy Moloch. The sisters can then say goodbye as their mother departed. Abbie realizes she is one in a long line of women tasked with fighting against the end of days and her legacy gifts her with a renewed sense of self and purpose.

After the defeat of Moloch, Abbie and Crane spend time cleaning up the remnants of the demon's evil and repairing the strain in their relationship. Frank Irving's return creates conflicting emotions in Abbie. Eventually it is revealed that her initial instinct is correct, and that he is still under Henry Parish's control. Jenny pleads with her to try to help Frank and Abbie agrees to look for a way to free him.

She later expresses concern that she and Crane seem to be fighting a battle with no goal. Crane tells her she must simply have faith. They then discover underground library compiled by Thomas Jefferson, and find a sentient hologram of the third US president that tells them that the library was made to provide the Witnesses guidance in their mission. Ultimately, Crane and Abbie decide to destroy the Fenestella and the tunnels around it to keep the creatures that guard the area from attacking any more people, they feel the loss of books is better than the loss of life.


Abbie travels to 1781

When eventually Katrina betrays Crane and joins forces with her son to awaken the witch blood within the residents of Sleepy Hollow using the Grand Grimoire, Abbie and Crane reaffirm their vow to back each other before all others, no matter who those others might be. Abbie understands things are difficult for her partner, but never loses faith in him. When the Witnesses do stop the witches, Abbie kills Henry in the confrontation. An infuriated Katrina casts the Traveler Spell and journeys into the past to make sure her husband will die in 1781, so Abbie cannot destroy Henry in the present. Abbie follows her to prevent her from killing Crane and changing the set time line. With great difficulty, she manages to get the 1781 version of Crane on her side, and together they approach Grace Dixon on the advice of Benjamin Franklin, who found Abbie delightful.

Abbie meets her ancestor, Grace Dixon, and together, they undo the Traveler Spell, making it as if it never was, and returning Abbie and Katrina to the future. Katrina then attempts to kill Abbie. A struggle with Crane, who tries to wrest a knife from her, results in her being stabbed, and she dies of her wounds in her husband's arms.

Season Three[]

After his wife's death, Crane leaves Sleepy Hollow, and is out of touch for nine months. Abbie spends that time speeding through training at Quantico and establishing herself in the ranks at the FBI. She ultimately returns to Sleepy Hollow when she is stationed at the White Plains regional office. It is then she finally hears from Crane again. After getting her partner released from an ICE detention center, she is confronted with the possibility that their mission as Witnesses is not truly over in the form of a mysterious Sumerian tablet Crane found in his family's crypt. She allows Crane house space as they adjust to their new reality.


The Mills sisters

After witnessing her partner's death at the hand of a demon, Abbie is surprised to find that her old flame from Quantico, Daniel Reynolds, is his replacement. Crane senses that their relationship was more than professional, prompting Abbie to warn him to mind his own business. Crane concedes in an attempt to be a good roommate. Later they both must confide in each other secrets they had been holding on to after a run in with a secret stealing demon. Abbie discloses that she had gone looking for her father in Crane's absence, and found him. She had not, however, worked up the courage to confront him. She does, however, come to a new understanding with Jenny after the events of The Sisters Mills.

Reynolds did not understand Crane's presence in Abbie's life, and always questioned her motives. He tries to force her to explain, but she keeps holding back, believing he would not believe her. She then turns in her resignation as an FBI agent to go after Pandora in an attempt to save her sister from the Eye of Providence's destruction. She was able to contain the energy before the Hidden One could take it, and she escapes through Pandora's tree just seconds before it was destroyed, trapping herself between worlds in the Catacombs.


Escaping the Catacombs

After spending what she estimated to be almost 10 months alone in the Catacombs, Abbie was found and visited by Crane's Astral form. He was able to discover that the Eye had the power to send her back to the real world. Pandora then appears in her Astral Form to retrieve the Eye for the Hidden One. Pandora cuts Crane loose from the tether to his body and tries to persuade Abbie to give her the Eye in exchange for Crane's life, and her freedom from the Catacombs. Abbie, furious but determined, smashes the Eye to prevent Pandora from using it. Pandora in turn abandoned Abbie in the Catacombs. Abbie was, however, able to escape the Catacombs through the well, following Crane's thinking, leaving the remnants of the Shard of Anubis and the Eye of Providence behind in the Temple of the Gods. When she returns to the Archive, she immediately calls to Crane, and when he heard her voice in the dark, follows it back to his physical form. In a joyous reunion, he says the Witnesses must always stick together no matter what.

Without sharing with Crane, it becomes clear that she had become obsessed with a mysterious symbol she found at the Catacombs. It distracted her, calling her attention, even when Crane's life was in danger. They soon discovered that the Emblem of Thura wasn't evil as they first thought, as it gave them the ability to telepathically see each other. It was a driving force to unite as one, symbolically demonstrated when they discovered the symbol split into two. When Reynolds was then forcefully introduced into the world of the supernatural, he became a part of the team and came to terms with her mission, and she retained her career. They promised to explore a more personal relationship when the battle was over.

When the Hidden One was able to regain his lost strength, he implemented his plan to destroy the world. Abbie and Crane sail down the Delaware River and then Abbie sang the national anthem to open the portal to the Underworld. She was terrified of returning to the Catacombs, but told Crane, “I'm scared out of my mind of seeing that place again, and no, I'm not letting you go without me. Whatever you do, I do, that's the deal.” Crane assured her he had faith in her, that she was the best partner he ever had, “You never waiver in your faith in what we do, in me, and you know how rare that is, don't you? When it concerns you and me, Lieutenant, there is no greater certainty.”


Return to the Catacombs

Within the temple, they found Betsy Ross, unconscious for centuries, she thought only months had passed. She recognized immediately, however, that this Crane was not her Crane, and that his heart now belonged to Abbie Mills. The Witnesses then follow Pandora's instructions on reviving her Box, only to discover the Box leeching away Abbie's soul, and slammed it shut. To have enough power to seal the Hidden One away for good, a Witness soul was the missing ingredient. Pandora prodded Abbie into giving the Box what it needed, “Give it your life!” Despite Crane's vehement objections, Abbie decided it had to be done, and with the final words, “Crane, never give up hope,” she vanished.

When next seen, Abbie is in a waiting room between life and death, not inside the Box. There, she is reunited with her mentor, August Corbin, and his son, Joe. Corbin explains that she has taken Crane as far as she can, and she is ready for the next adventure. Crane, however, has not given up trying to get her back. In confronting Pandora, the loss of Abbie almost overwhelmed him, and Jenny told him, “She sacrificed herself so that you could be here and win the day. Don't you dare let that be for nothing!” When Crane then bested Pandora and she was dying, she realized, “You love her, don't you? She is your hope... your everything.” Then tells him Abbie is not in the Box, but dead. When the Box then explodes and knocks Crane unconscious, he meets with his partner for the last time in that waiting room between life and death.

He first sees her as they first met, but this time, she says, that it is time to say goodbye. He objects, and they are then at the Archives. She tells him he set her free, and that as Witnesses they are eternal souls. They are then on her porch, and she tells him her job is done, and he laments, “What is there for me in a world without you?” She tells him it isn't so much a goodbye, but more “until we meet again.” She then orders him to, “Honor our bond, and be brave. Be strong. I know you will be, you're my guy... always.” When she offers a fist bump, he instead kisses her hand, and she smiles, “My, my, be still, my beating heart.” And then, he awakes and Abbie is gone. He tells the grieving Jenny, “she is, and will forever be, ours.”

Her tombstone, which Crane visits often, read "She Bore Witness."


Abbie is a tenacious and courageous woman, often putting other’s needs above her own. Abbie, however, keeps a tight reign on her emotions. As a result she is often reserved and slow to anger, but beneath the tough exterior is woman who feels very deeply. She is empathetic, as displayed in her repeatedly choosing to attempt to talk down perps rather than make shows of force. She also has a soft spot for children, while fighting against the Pied Piper she essentially offered herself up as bait is order to track down a missing girl.

Abbie is also both patient and kind. She is an good teacher, introducing Crane to the modern world with efficiency and ease. She lets him come to his own conclusions and guides him without patronizing. Furthermore, she was the only person to suspect that Crane wasn’t crazy from the onset, and might have been telling the truth about his identity. On his first night in his hotel room, she makes sure to place sticky notes all around his room explaining how to turn on the lights and make coffee, take a shower, or watch television, “it's like theatre.”

Abbie is knowledgeable, practical, intelligent, and at times calculating. She has a knack for profiling and her skills helped track down both Henry Parish and Abraham Van Brunt. She is also very curious. When she first meets the angel, Orion, she jokes with him and asks about dinosaurs. Orion calls her clever. Abbie ultimately has a skeptical bent. She initially pushes back against the idea of the supernatural, and though she does eventually commit fully to the cause, she continues to question why she was chosen. She is the first to offer up science as an alternative to magic, regularly finding ways to resourcefully replace spells with generators, chemistry, and ultraviolet light.

Abbie has dealt with a lot of hurt in her life. As teenager she went down a dark path though she not once lashed out at others. Those experiences left her guarded but also wise; she understands that sometimes love isn’t enough. Abbie can and does make tough decisions. She killed her friend, Andy Brooks, in order to give him peace. She also frequently argued the necessity of killing Henry, and was proven correct in the end, and by pulling the trigger herself saved Crane from carrying the burden of killing his own son.

Abbie has shown to be both protective and loyal to those close to her, caring for their well-being. When her mentor, August Corbin, was killed, she was devastated by his death. She worked to save his son, Joe Corbin, even when everyone else thought hope was lost. Crane, Jenny, and Frank particularly have benefited from her steadfast and heartfelt care.


As a FBI Agent, Abbie was trained at Quantico. Abbie is very skilled in marksmanship and is capable of utilizing a pistol as well as numerous firearms. Abbie is also shown to be well trained in Close Quarter Combat. Due to her past life as a criminal, Abbie has a talent for lock picking. She also displays a moment of swordsmanship, after wielding a sword and flawlessly beheading a doppelgänger of Crane while trapped in Purgatory.

Abbie has had prophetic dreams, assisted in casting spells, been visited by spirits only she can see, and had detailed visions of the past, it is unclear, however, if these experiences are due to her status as a Witness or a benefit of her bloodline.

A possible drawback to these powers is that after surviving, then leaving, the Catacombs, Abbie obsessed with a specific symbol she associates with a supernatural being that saved her life in the Catacombs. She paints the symbol on her shed wall and pledges fealty to the being it represents.


Ichabod Crane[]

Ichabod Crane

Partner and fellow Witness

Ichabod Crane is Abbie's fellow Witness, partner, and very close friend. She met him when he first awoke in modern day Sleepy Hollow. Initially, she was inclined to believe he was crazy but when he started to relay accurate details of the Headless Horseman who killed her mentor, Sheriff August Corbin, she slowly began to believe his tale. They began to work together to solve the murders of Corbin and Reverend Knapp and eventually learned that they are part of a plan to avert the End of Days. They learn that she and Crane are the Witnesses spoken of in the Bible and decide to take on the task of preventing the Apocalypse rather than simply watch it happen. Abbie is Crane's guide to the 21st century and patiently helps him get acclimated to living in the modern world. She frequently teaches him about new technologies, changes in language, and the social norms that have arisen in the 230 years since he fell. Knowing what a big adjustment it is for him, Abbie does her best to reassure Crane that he has a home with her in the modern age and though it takes a while, Crane eventually resolves to call the new world home, and calls Abbie his greatest boon. They have grown to understand each other intimately and have developed a strong and affectionate friendship.

As Witnesses, their relationship is a bit more contentious, with them almost constantly butting heads. Initially, it is Abbie's resistance to believing being a Witness that is source of a tension, but alters as she and Crane have very different ideas as to how to approach the conflict surrounding his family. Later, this comes full circle in Abbie assuming that her role as a Witness is over and tries to move on with her life while Crane steadfastly believes their mission is still relevant. Despite this, when they are on the same page, they work very well together. Crane always inspires faith and trust in Abbie, and Abbie in turn, is always there to remind him he is human and that it is okay to make mistakes. Abbie is fiercely loyal to Crane, it can be argued that he is the single most important person in her life besides Jenny, and he was her touchstone while trapped in the Catacombs. She's said that her faith in Crane is her greatest weakness. She confides in him and is able to sense when something is bothering him. She'll often do small gestures of kindness for him whenever he's feeling down, or they've been through a particularly rough time, and always tries to get him to see the positives in a situation. She worries over him whenever he decides to take on a task alone, and has saved his life more than once. Even when their friendship is tested, Abbie and Crane have shown that they are willing to be honest with each other and work through any disagreements or hurt feelings, coming out stronger for it in the end.

Jenny Mills[]

Jenny mills


Jenny Mills is Abbie's strong-willed younger sister.

As children, Abbie and Jenny were very close, but they were both subjected to traumatic childhoods that included an encounter with a demon in the woods followed by their mother's incarceration in Terrytown and a string of foster homes. After Jenny told the truth about what they saw in the woods, Jenny was sent to a mental institution. Abbie escaped a similar fate by refusing to back her sister, saying that she saw nothing, Jenny always saw Abbie's actions to be a betrayal. Jenny's anger at her sister continued to fester over the years, spurred on by a demon named Ancitif that repeatedly took possession of her.

During these bouts of possession, Ancitif wanted Jenny to take Abbie's life. Jenny, fearing that she would actually be forced to act on that, would often purposefully get arrested; in order to keep herself as far away from Abbie as possible. It is later revealed that she was marked that day in the woods and Moloch had planned to use her to kill Abbie and hasten the coming of the apocalypse.

Jenny was reluctant to forgive her sister even after Abbie apologized, but they eventually manage a working relationship early on, before they came to realize they were all the family each had. The more they interacted, the more Jenny visibly softened around her sister. When Abbie found out about the possessions and Jenny’s sacrifice in order to keep her safe, they hugged for the first time in years. Abbie came to rely on Jenny's know-how involving just about all things supernatural and they formed two-thirds of a formidable team.

Ezra Mills[]



Abbie's estranged father. He had difficulty dealing with Lori Mills and began drinking. When he joined the Navy to provide health care for the family, he eventually just disappeared from their lives. After Lori was committed to Terrytown, he left the Mills girls to fend for themselves, when at some point he learned that Abbie was indeed one of the Witnesses.

By the time Abbie became an FBI Agent, she was emotionally ready to track him down, although she did not manage a face to face. Jenny told Abby she had found Ezra some five years previously and had not confronted him either. When Abbie was trapped in the Catacombs, Jenny stole Ezra's lighter for the ritual that would help Crane use his astral form to locate her. When Abbie returned from the Catacombs, she finally met with Ezra. He said he left when they were living in two separate realities. He and Abbie achieved an acceptance but she never truly forgave him for leaving. At the time of Ragnarok, however, he stood by his daughters as he provided Jenny with weapons and witnessed the death of Joe. After Abbie's death, he told Crane that Abbie's eternal soul lives on.

Lori Mills[]

Lori Roberts


Abbie and Jenny's mother, she had been suffering from spiritual torture since Abbie was born. Her condition got worse as her daughters grew up, at one point she attempted to kill herself and Jenny with auto exhaust until she realized what she was doing and broke out of the garage with an unconscious daughter in the back seat. Eventually, she was arrested and committed to Tarrytown by Reyes, while her daughters went into the foster system. She would eventually commit suicide while incarcerated.

In the episode, Mama, Abbie, Jenny, and Hawley found evidence that Lori had been forced into suicide by an agent of Moloch, who was still working in the wards, forcing others down the same path. Lori haunted the hospital in an often unsuccessful attempt to aid targeted patients. When her daughters found her, she pointed them to her journal, then in storage and an incantation Jenny used to save Abbie from Lambert's attacks. She was summoned by a ritual by the sisters to finally say goodbye to her. She said that she was proud of them, that she knew that Abbie was the next Witness, and that she watched over Jenny when she was in Tarrytown. She directed them to find a sacred weapon hinted at in her journal, something passed down by Grace Dixon. She knows that the fate of the world is been carried in her daughters' hands so she can rest in peace.

Frank Irving[]


Friend and colleague

Frank Irving took command of the Sleepy Hollow Police force after August Corbin's death. Eventually, he was made privy to the supernatural war Abbie and Crane were aging and was included on their team where they worked together tracking mysterious happenings in Sleepy Hollow.

Frank liked to hold on to his skepticism, but after seeing the Headless Horseman first hand, Frank becomes a convert. He and Abbie have a kind of camaraderie that is an extension of their being cops together, they are also soldiers fighting against the apocalypse. Upon his resurrection, Abbie is suspicious of him, fearing that he is still under the control of the witch, Henry Parish, and is eventually proven correct. But; with Henry's death, Frank is freed and she embraces him once more.

Andy Brooks[]


He was once a respectable police officer working in the Sleepy Hollow Sheriff Department, a friend and colleague of Abbie Mills, they went to the same college. He had a deep unrequited love for Abbie. At some point, he willingly sold his soul to Moloch, becoming the demon's agent. After the demon killed him, he was resurrected again to serve. He claimed that he was the only one who could protect Abbie, appearing at her home and in the tunnel to contact her.

As Andy became a full-fledged member of Moloch's army, he was shot by Abbie and wound up in Purgatory. He later served her as a guide during her imprisonment there; despite the fact that; if Moloch caught him, he would be "torn to pieces". Abbie could still reach the man beneath what Moloch made him and he finally begs her to destroy him; which she does.

Grace Dixon[]



Abbie's distant ancestor. She has helped her family in their roles via the journal she wrote and passed on. She was first encountered by Abbie in Frederick Manor, Grace's ghost appeared in the manor beckoning Abbie who followed the ghost to see the vision of Katrina giving birth. Grace later appears and lights the way for an exit for Abbie, and her friends to escape the Tree Monster. In Tempus Fugit, when Abbie had traveled in time, Grace was met by Captain Ichabod Crane and Abbie when they traveled to Fredericks Manor when told there was a possibility that Grace could reverse the Traveler's Spell cast by Katrina Crane.

Abbie told her she was her descendant. Grace then understood, and surmised that Abbbie is the second Witness. She was able to create a time reversal spell, the Abiero Spell, to help Abbie return to her own time without changing the course of history, even though, the energy surrounding the mansion would be weakened. Before Abbie returned to the present, she told her that a crucial battle was about to start. And it was thanks to her journal and her experiences that helped Team Witness survive.

August Corbin[]

August Corbin


August Corbin was the former sheriff of Sleepy Hollow and Abbie's mentor and father figure. He caught Abbie shoplifting from a store and gave her the choice of going to jail or straightening out her life. That meeting changed Abbie's life and inspired her to go into police work. He trained her and she quickly rose through the ranks to become a lieutenant. The two are implied to have been work partners on many cases and he gave her advice and encouragement whenever she needed it.

August also took Abbie's sister Jenny under his wing though he kept that knowledge from Abbie. Jenny, Abbie, and Corbin's son Joe have come together in a kind of de facto family to carry on his legacy. August was murdered by the Headless Horseman as the first casualty of the war against humanity. His death affects Abbie greatly and forces her to confront her past and the supernatural history of her town. He appears to her in a vision to give her one last piece of advice and he's often referenced by Abbie in the course of working cases since he investigated many of the otherworldly happenings in the town and logged them in his files.

Daniel Reynolds[]


Abbie's superior officer and past lover, he arrived in Sleepy Hollow as the replacement for the deceased agent Granger. He had met Abbie at Quntico and were in deep competition while they were in training as FBI agents. By the time they were relocated from Quantico to Westchester County, their relationship started to get very complicated.

While Abbie was secretly fighting Pandora, Daniel always questions her motives, her sister, and Jenny's boyfriend, Joe. It eventually came to a point where she quit her job and gives up her badge just before she disappears into the Catacombs.

Upon Abbie's return weeks later, Daniel still holds feelings to her and tells her he never submitted her resignation. He re-instated her as an agent. When he is present as she and Crane are attacked by a supernatural creature, he gets a baptism by fire into her world. He joins her in the final battle, and they make plans to get together when the battle is over – that was never to be.



  • The name "Grace" is from the English word grace, which ultimately derives from Latin gratia. This was one of the virtue names created in the 17th century by the Puritans. The actress Grace Kelly (1929-1982) was a famous bearer.[3]
  • The name "Abigail" is from the Hebrew name אֲבִיגָיִל ('Avigayil) meaning "my father is joy". [4]

Production Notes[]

  • In the original script[5], Abbie's last name was Archer instead of Mills. In addition, she was a Detective instead of Lieutenant.
  • Abbie's birthday as shown on her ID in "Tempus Fugit" indicates she was born on December 23, 1973,[6] that would mean that she was over 40 when she died. On her tombstone, her birth year is inscribed as 1986[2] which is more realistic as that would make her 30.

Behind the Scenes[]

  • According to sources, Nicole Beharie had been wanting to leave the series for some time before her character's death. The character, sources say, originally was supposed to be killed off during the mid-season finale, but insiders are said to have gotten cold feet and decided to keep her on until the end of the season.[8]
  • Many fans wanted for Crane and Abbie to enter a romantic relationship, this did not happen in the show.
