Grace Abigail "Abbie" Mills (Nicole Beharie) is a police lieutenant in the small modern-day town of Sleepy Hollow. At a very young age she had a mysterious encounter with a demon named Moloch that upended her life and led to a long term estrangement between her and her sister that she is just now repairing. Upon meeting Ichabod Crane, she learns she is one of two Witnesses foretold in the book of Revelation to fight against the coming apocalypse. Abbie and Ichabod, the show's two main protagonists and biblically ordained Witnesses, must team up along with their fellow comrades, in order to fight Moloch's minions, Hessian soldiers, and the Four Horsemen of the Apocalypse.



Before Abbie became a cop at the Sleepy Hollow sheriff's department, she had a troubled childhood, which included brief run-ins with the law. Both Abbie and her sister, Jenny Mills, dealt with instability at home as children. Their father was an alcoholic and their mother though loving, struggled with mental illness. It is also implied that the family was not financially well off. But Abbie and Jenny were very close, often locking themselves in their room to play with their dollhouse and escape their parents. Also of note, was their mother making Abbie and Jenny memorize and recite bible verses. This as well as Abbie's relation to Grace Dixon has led fans to speculate that one or both of Abbie's parents may have known their child was special in some capacity. Eventually, their father left the family and their mother was institutionalized, leaving Abbie and Jenny to be placed into the foster care system. Abbie confirms in a conversation with Ichabod that her mother passed away sometime later.

Abbie and Jenny apparently cycled through a few homes before settling in a place that Abbie felt was a good fit. During that time Abbie taught Jenny to pick locks, and they seem to have acquired a taste for criminal activity. Around the age of 13 (give or take), 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 due to Moloch sealing away their memories in purgatory. After being found by a civilian from a local search party, the girls were then taken into police custody and questioned rather callously. 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 didn't 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 that day and her feelings of resentment and guilt towards her sister. By the time she was 16, she was using drugs and pursuing a life of crime. After a botched attempt at robbing a pharmacy, she is taken into custody by Sheriff August Corbin but instead of arresting her he offered her a chance to change. She accepted and under Corbin's tutelage took a class in latin, graduated high school, went to college, rose to the rank of Lieutenant as a police officer and was accepted into an elite FBI entrance program at Quantico to become 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 OneEdit

Detective Abbie Mills is a smart and tough detective with the Westchester County PD in the small town of Sleepy Hollow. She is poised to leave the town in a week for the FBI Academy in Quantico, Virginia, but the gory slaying of her mentor and partner by a headless horseman derails those plans. Unwilling to divulge the more supernatural elements of partner's murderer without further proof she teams up with Ichabod Crane, an unwilling fugitive from the past who claims to be soldier in the Revolutionary War and the only person that can collaborate her story. Together they learn they are the Witnesses foretold in the book of Revelation to fight against the coming apocalypse. Throughout the season, Abbie struggles with the death of her mentor, her skepticism, her partnership with Ichabod, rebuilding her relationship with her sister and accepting her role as a witness.




Jenny MillsEdit

Jenny mills
Jenny Mills is Abbie’s strong-willed and snarky younger sister. As children the sisters were very close. Sadly, they were both subjected to traumatic childhoods that included a string of foster homes and an encounter with a demon in the woods. Jenny was sent to a mental institution after she insisted on telling the truth about what she saw that day. Abbie escaped a similar fate by lying, but Jenny always believed Abbie’s actions to be a betrayal.

Jenny’s anger at her sister continued to fester over the years, spurred on by demon named Ancitif that repeatedly took possession of her body. During these fits of possession Jenny would make threats against Abbie’s life. Jenny, fearing she would actually go through with the threats, 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 do manage a strained working relationship early on. Abbie came to rely Jenny’s know-how involving just about all things supernatural and they 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. The first season closes with the two sisters closer than ever: Abbie declaring that she wants to confront Moloch for both their sakes and Jenny promising to hunt her down if she isn’t back by sunset.

  • Abbie is particularly talented at picking locks.
  • Abbie is very skilled as a police woman having risen through the ranks fairly quickly for someone that young and it has been hinted that she has a talent for profiling.
  • Abbie is very experienced with modern weaponry, as well as boxing.


Season 1Edit


'"Okay. I'll play along here. I am a black female lieutenant for the Westchester County Police Department. Do you see this gun? I'm authorized to use it. On you."

"Wait, back up, you're offended?" -Abbie to Ichabod when he expresses offense to the insinuation that he endorses slavery 

"Congratulations. Slavery has been abolished 150 years. It's a whole new day in America."

"Two hundred and fifty years, huh? Civil War didn't wake you? Noisy neighbors to the south. Did you get up to pee? Don't know about you, but I'm getting up to pee every 75, 80 years."

"Convenient part for me is if you tell anyone, no one will believe you." -Abbie to Ichabod about believing his fantastical story

"And even if I thought what I saw was possible, I would be alone again arguing a case i cannot understand based on something I cannot explain. Let's. Go."

"Back in High School... me and my sister Jenny were walking home one night in the forest. All of a sudden there were these four white trees; there was something not right about them. And then there was this voice. I couldn't see it clearly, I couldn't tell if it was a person or a thing. And, uh...We blacked out! Next thing we knew someone found us on the side of the road, and everyone said we were crazy... I guess after a while Jenny started believing it. [...] But then you showed up. And everyone said that you were crazy. So I guess I just know what that feels like." -Abbie to Ichabod

"Stand down and let me do my job!"

"Walk fast. We've got about one minute until she realizes that court order is a practice sheet from my academy exam."

"I think this is where I'm supposed to be." -Abbie to Irving about no longer leaving Sleepy Hollow'

Blood Moon

"That's one way of putting it, another way would be to say that he was killed with an axe by a man with no head without making me sound crazy" - Abbie about Corbin

"Okay. It's a little early in the morning for a constitutional debate - have a donut hole."

"I'm trying to hold onto my sanity! Not to mention my job."

"Do me a favor and don't look at me like I'm the one that's crazy okay? I've had enough of that for one lifetime."

"Somehow you fell in love. You get married, but the whole time you have no idea that your wife is a witch?" - Abbie about Katrina

"Here's what we can do: No more first-hand accounts of witches, or founding fathers, or donut tax outrage unless you want to be sent back to the asylum."

"You gotta give me a minute to find my feet here. I was on my way to Quantico two seconds ago to be a criminal profiler, and now I'm profiling a witch! [...] I mean what are we supposed to do, put out an APB on a woman with warts and a broom?"

"So I changed, right there. I got more fathering in those five minutes than I got my whole life." - Abbie about Corbin

"He's my ex. We were not bethrothed, there was no bethrothing. And we've got bigger problems." - Abbie about Luke "I will literally pay you to stop talking."

"Jolly good. Let's set her aflame and bury her bones where she'll never find them!" - said with a fake and comedic British affectation

"I am so far down the rabbit hole here. I never thought I'd say this, not in a million years, but I just want to go back to the way it was... before."

  • Corbin : You look lost, kid!
  • Abbie: What is this? I'm dreaming right?
  • Corbin: What difference does that make? I'm here right now, aren't I? With you?
  • Abbie: Look if you're gonna haunt me... be helpful? Okay?
  • Corbin: Okay. What seems to be the problem?
  • Abbie: [sighs] What seems to be the problem... How about what the hell is happening here? You were ahead of me the whole time, were you ever planning on telling me anything?
  • Corbin: Would you believe me if I did?
  • Abbie: Maybe!
  • Corbin: Maybe not. You've spent a lot of time running away from what happened to you, Abbie.
  • Abbie: I asked you to be helpful. I don't know how to do this.
  • Corbin: You're scared. Anxious.
  • Abbie: Scared? Yeah. I'm furious. And outraged that you didn't tell me-!
  • Corbin: Good. That's progress! Ever since you were little you let your life be ruled by fear. You're so afraid of what you don't understand that it kept you from seeing who you really are. What you're meant to do.
  • Abbie: Which is?
  • Corbin: The only person that can tell you that is you. That's what faith is, honey. 
  • Abbie: I really miss you.
  • Corbin: Don't be afraid of number forty-nine. That's where you'll find you're not alone.

For The Triumph Of Evil

  • Crane: You had a prophetic dream warning you of an impending event.
  • Abbie: Which stands to reason, given that, according to Washington's Bible The Book of Revelation foretells of two witnesses, I know. I am a cop in a small town. So let's not curse me as a capital "W" witness just yet.

"Unless you have an encyclopedia of faceless nightmare monsters, why don't we just start with a little regular detective work here?"

"I saw a demon. I saw a demon in the woods and I lied to protect myself. I was a coward and I betrayed my sister. I turned my back on her when she needed me. And I will not do it again. It was my fault. You can come at me all you want, but I see you. I'm not afraid anymore!"
