Mr. Robot Wiki

Dominique "Dom" DiPierro is a FBI agent who investigating the Five/Nine Hack case. She is played by Grace Gummer.


Dominique was raised in Teaneck, New Jersey. Her parents bought a seemingly rare clock from the local Kmart, keeping it in the family room. Her mom Trudie lives in Philadelphia. She has an uncle Chris in Dallas. She has a kid brother, Joseph, for whom she rolled joints in high school. Joseph lives in Morrisville, PA and has a 4 year old son Jaime. Her older brother is named Jerry.

Mere days before graduating from law school, Dom received a marriage proposal from the person she was dating. She excused herself to the restroom, left out the back of the restaurant, and changed careers, joining the Federal Bureau of Investigation.

Season 2

Dom is first seen at a deli, drinking five hour energy and making small talk to the clerk about his family when the customer behind her gets impatient. She calls him a "dickhead" in Persian, talking to the Iranian clerk.

Later she is seen in a dim room full of whiteboards when a fellow FBI agent takes her to an interrogation room where Gideon Goddard is waiting. (“”)

On June 17, Dom is reading about the murder of Gideon at 4 in the morning while watching reality TV in bed. She gets ready for work, fixing her hair and makeup while drinking coffee, and stares blankly into the mirror. She reports to a murder scene where the NYPD found DiPierro's name among a list of FBI contacts printed out by deceased computer criminal Leslie Romero. Unimpressed by the NYPD's amateurish investigation, Dom takes a picture of the list and leaves them with her card.

On the night of June 21, she is masturbating on a cybersex chat room, but can't seem to find pleasure. (Trivia: her cyber sex partner's screen name is based on the character 'Happy Harry Hard-on' from the 1990 Christian Slater move 'Pump Up The Volume'. She asks Alexa when the end of the world is. Dom retrieves her phone from her safe and looks over the FBI names. The next day she returns to interview the Romero's eldery mother, winning her favor by rolling joints. DiPierro discovers a flyer for an "End of the World Party", and follows it to the Fun Society arcade in Coney Island. (“eps2.1_k3rnel-pan1c.ksd”)

Forensics specialists search the premises, finding a single spent bullet casing.The team are tracking down people who attended the party from the social media evidence and looking into the name "DJ Mobley." DiPierro's report on the arcade is submitted into evidence, where it is shared in the joint investigation with the Chinese Ministry for State Security. (“eps2.2_init1.asec”)

DiPierro visits Steel Mountain's Albany facility, examining a Raspberry Pi wired into the climate control system. Afterwards, she returns to the FBI's secure floor at the E Corp Headquarters. A colleague shares a recurring nightmare, where she is observed by a masked man; Dom flatly states that she doesn't dream before turning conversation back to work.

Agent Santiago's FBI task force travels to Beijing for a meeting with representatives of the Ministry of State Security. At the airport, Dom is shaken by an brief encounter with two masked men, who watch her pass by on the escalator.

In a publicized diplomatic meeting with Minister Zhang, Dom speaks out of turn and requests all intelligence on the Dark Army. After a long, tense silence, Zhang promises to deliver dossiers on the hacker group, and invites them to a reception the night before the tour.

Dom excuses herself from the party in search of a bathroom. Instead, she discovers a room full of clocks, which Zhang finds her admiring. In a coded discussion of identity, the two get to know each other: Zhang quotes Macbeth to explain his fascination with time, and Dom explains that she is "disgusted and fascinated" by the selfish brutality of the world. Zhang shows her artwork critical of the Communist regime, inquiring further about her background and choice of career. Dom attempts to deflect the personal question, but ends up telling the story of her law school breakup. Moved by her story, Zhang shows Dom a collection of traditional and contemporary Manchu dresses, which he claims belong to his sister. Zhang reflects on the possibility of alternate universes and timelines before the clocks begin to sound, and he excuses himself.

The next morning, Dom confers with her colleagues in the hotel lobby, disappointed that fingerprints could not be recovered from the Raspberry Pi. Suddenly, two masked gunmen enter and open fire, killing several agents. Dom takes cover, finds a weapon, and wounds one in the leg; the gunman immediately kills himself. The other has her cornered, but he also commits suicide. (“eps2.3_logic_b0mb.hc”)

Back in the States, Santiago hands down a recommendation for four weeks psychiatric leave. Dom objects, finding fault with Santiago's double standard and insisting that the attack was intended to disrupt the FBI's investigation into the Dark Army. Santiago stands by the official Chinese story, which places the blame on Uyghur separatists. Dom insists that the gunmen could have pressed their tactical advantage, but instead "erased their history".

Visiting the deli, Dom learns that Ahmed is closing up shop. The cash allowance imposed by the Five/Nine Hack has devastated his small business. Dom expresses her condolences, trying unsuccessfully to lighten the mood by ordering one last sandwich. (“eps2.4_m4ster_s1ave.aes”)

On July 3, Dom spots Angela Moss crossing the restricted floor at E Corp Headquarters. She introduces herself, and questions why Angela was on the FBI floor during lunch hour; Angela says she was making a lunch date, and tries to get back to "a really important call". Dom pries further, tracing Angela's career history from Allsafe to E Corp. She wants to take a statement, but ultimately leaves Angela to her work.

DiPierro immediately goes to check the security footage. The entire archive is corrupt. She tells others to sweep the 23rd floor and check Angela's computer, although the latter is likely to be clean. She then says she's off to find a 4th of July barbecue to be miserable at. (“eps2.5_h4ndshake.sme”)

The next night, Dom is interrogating a banker who illegally owned the gun from which the arcade bullet casing came. She offers immunity in exchange for a name.

The same night, the FBI pick up Sunil Markesh. She offers condolences for Romero before explaining how she linked the name DJ Mobley back to an Internet fan page he made. Dom wants Tyrell Wellick. Mobley wants a lawyer. Meanwhile, the leaked conference call about Project Berenstain is causing quite the scandal around the FBI. People are being fired. Dom is told to release Mobley after holding him for 12 hours with no evidence. The next day, Dom speaks with an agent who was Angela's date on 4th of July. She didn't talk.

On August 7th, Dom shows up at Angela's apartment with her favorite food from Nia's Gyros. She lets herself in and starts telling the story of a rare dream she had of a beautiful, "sexy" woman drowning her. She tells Angela that Ollie told the FBI about the Allsafe CD two months ago and they have been tailing her ever since. They know she's been freaking out. Dom offers a helping hand, because the next person coming after her won't bring food. She lets her know that in the dream, stopping the struggle is how she survived.

In the middle of the night, Dom is called to the smart house of Susan Jacobs. The sketch of someone breaking in matches the sketch Ollie described of Cisco. Dom asks why the FBI searched the house instead of staking it out. The investigator discovered that Susan Jacobs hasn't shown up for work and is now considered missing.

Dom takes the two matching sketches to Santiago to pursue the case. Santiago wants to put out a B.O.L.O. on the news, but Dom fears what the Dark Army is capable of. An ER nurse calls that she has seen the man. Dom arrives and deduces that Cisco and the woman he was with didn't run and plan to return for their friend. Dom searches the local area for places to eat. She finds Cisco and Darlene at a diner and confronts them. At the same moment, two masked gunmen arrive on a motorcycle. One opens fire through the window. Dom wounds him and he commits suicide. The other drives off as police swarm and a bloody Dom runs out into the street.

Dom is taken to the hospital, where she explains that the blood on her face isn't hers and she wants to get back on the case. Santiago is there to persuade her to take time off. He kicks other agents out of the room. Dom asks to get FBI Director on the phone and that the Chinese government is behind this act of war. Santiago refuses, explaining that the Chinese have bailed out E Corp and the United States won't endanger global economic recovery by straining international relations. Dom is sent home while her boss promises her the interview of witnesses in a few hours.

At home, Dom is slow to wash her face and change clothes. As she tries to fall asleep, she begins asking her Amazon Echo Alexa questions to form a connection. What's her favorite color? Are they friends? Is Alexa happy? Does Alexa love her? Dom becomes emotionally distraught before falling asleep.

She later interrogates Darlene with Santiago. Dom gives her condolences for Cisco's death, while Darlene pleads the 5th amendment. Santiago threatens her with the Patriot Act, stripping her of her rights because she isn't a TV character on Burn Notice or the USA network. He leaves the room.

Dom tries to appeal to Darlene on the basis of being Jersey girls in over their heads. Darlene is allowed to smoke as she pleads ignorance of what was simply a night out with the love of her life. Darlene refuses the good cop routine and asks for a lawyer. Dom chuckles and leave. She asks Santiago for another one on one encounter.

Dom lays out the evidence: the film equipment and fsociety mask found at Cisco's apartment; the bullet casing found at the arcade which is linked to a gun whose owner identifies Darlene. Vincent, who Darlene is assured will survive, along with the other arrested foot soldiers also identify Darlene as their leader. Dom reflects on the situation, that they are involved in one of the biggest events in world history. She explains that she has no life and has been working the case extensively.

She then brings Darlene out into the hall where her FBI colleagues stop and stare. Dom leads her to a room where the walls are covered in evidence. The FBI has linked Cisco, Mobley, Trenton, Romero, Gideon, Darlene, Angela, Elliot and Tyrell in a grand web of connections. Dom reveals that the FBI has been sitting back, waiting for the man in the middle, Tyrell to become vulnerable. She says that Romero was simply killed by a stray bullet. Darlene says, "You've got to be fucking kidding me."

Season 3

On September 17, Darlene is sitting on a couch in an FBI safehouse watching the new fsociety video on a lap top with Dom, Santiago, and another FBI agent Norm . Darlene assures them it isn't fsociety. Dom contends that it's from the same Vimeo account. Darlene thinks it must be Dark Army, given access by Cisco. Santiago gets angry, reminding her that she is a Confidential Human Source with the mission to get intel on Tyrell from Elliot. Darlene says Elliot isn't talking to him, having asked her brother 5 weeks ago. She invites them to bring Elliot in to ask him. They decline tipping him off as that would violate her immunity. After Darlene vehemently denies any relationship between the two, Dom plays the prison call from June 16 when Tyrell called Elliot. Darlene is surprised.

Later that night, Dom and Santiago talk in the morgue where Joanna Wellick’s skull is cut open in autopsy. She notes that the shooter didn’t survive and the driver is expected to survive with FBI waiting at the hospital. Santiago says nobody saw them take her body and that her son is going to social services, not the relatives, as to not tip off Tyrell. Dom believes Darlene about Elliot and the video being Dark Army. Santiago tells her that she's in charge to Darlene and society gets a text that they have lead on the video. He is worried Darlene is a flight risk, but Dom says she's good, "Trust me."

The next night, Elliot's monitor is broadcasting to Dom’s computer at the safe house. She congratulates Darlene on a good job of planting the connection when she stayed at his apartment the previous night. Darlene leaves to sit on the porch.

The next day, Dom is returning to the safehouse, located in a trash ridden part of town. Kids on hoverboards ride by and she sees a Comet Electric van across the street. It's 8:01 AM. She's brought coffee for Norm and he notes that E Coin has driven the dollar down. He says last night the only thing of note from their surveillance was an email with link from Elliot’s computer. Their audio recording is the song "One Week" by the Bare Naked Ladies. Dom laments that the song will be stuck in her head all day. They hear a noise outside and see on the security cameras that a man is breaking into Darlene’s apartment downstairs. Norm says Darlene is out. Dom asks about the email which led to nothing, but deduces that the link was to trace it back to them. Dom watches as Elliot is inside the room below them, taking his hood down and looking around. (“eps3.1_undo.gz”)

After Dom spends a drunken night out with Darlene which leads to them sleeping together, she catches Darlene breaking into her safe and demands her to explain herself. In the interrogation room, Darlene gives her a solution to solving the September 29 Attacks, which Dom believes would work - they would have nothing to lose. Santiago, worried that his status as a mole would be exposed if Darlene's solution works, changes the subject. He refuses to listen to her because she was "sleeping with a CHS" and although Dom argues that she didn't break the rules, he uses this as an opportunity to take Santiago off the case and tells her that she is being "replaced by Agent Kaz". (“eps3.8_stage3.torrent”)

When she hands over files related to her case to Agent Kaz, he tells her that he has no idea of this change in assignment and is instead "heading to JFK in 20 minutes". Suspicious about this, she heads down to the car park and spots Santiago about to drive off with a handcuffed Darlene in the car. Dom interrogates him and doesn't believe the excuse he provides her for trying to drive off with Darlene. She is about to make a phone call which would've blown his cover when he knocks her out. She wakes up in the car, handcuffed next to Darlene and comes to the realisation that Santiago is the mole. After being driven to an abandoned barn, she witnesses Santiago being axed in the chest by Irving, who then tells her that she will take over as the next mole for the Dark Army. After refusing vehemently, Irving threatens the youngest DiPierro family member Jamie, her mother Trudie, her uncle Chris and her older brother Jerry whilst naming each of their locations, hobbies and habits, emphasised by an axe to Santiago's body each time. Left with no choice, Dom gives verbal confirmation that she will take over as the next FBI mole. When they are released from captivity by the Dark Army, she confronts Darlene while crying and tells her "you've taken everything from me".(“shutdown -r”)

Season 4

Around Christmastime, Dom has moved back in with her mother. Still on edge from being forcibly recruited into the Dark Army, a paranoid Dom mistakes a repairman for one of their agents and pulls a gun on him. Following the false alarm, Dom angrily reminds her mother not to hire anyone without her permission. At dinnertime, her mother invites over Janice, a neighbour, who innocuously tries to set the two up together. Janice later tells Dom that unless she goes back to work the next day, she will be forced to slit her mother's throat "from mouth to cunt." (“401 Unauthorized”)

Dom is clearly nervous during a discussion with Agent Horton regarding Santiago's disappearance. She tells Horton that she believed Santiago was a double-agent who was working with some "awfully dangerous people." Once asked whom she believed Santiago was working with, she names the Trujillo drug cartel. Afterwards, she phones Janice and informs her that she has told Agent Horton the cover story, which she says that she's "99.9% sure" that he bought. Later, she receives a text from Janice saying, "I'm awfully sorry about your co-worker." A second later, Special Agent Kaz pulls her aside to show her news footage about a suicide jumper, and asks her about the emotional status of Agent Horton earlier that day, when the two of them met. He reveals that Agent Horton is the suicide jumper, and Dom later receives a text from Janice stating, "99.9% sure isn't good enough. Let's strive to keep it 100". (“402 Payment Required”)

Feeling lonely on Christmas night, Dom pleasures herself to Darlene's interrogation video, before switching to an online webchat. She exchanges vulgar messages on an online webchat before telling the recipient of her messages, Happyhardonhenry806, that she is actually into women. Ironically, the person she is receiving texts from says she is actually a woman. Dom offers to see her in real life and "be lonely together", which the recipient agrees to. They meet and Happyhardonhenry806 starts to drown her in the bathtub when Dom wakes up from a disturbed sleep. (“404 Not Found”)

Dom's plans for the day are put to a stop when Janice tells her to look into the FBI investigations on the Dark Army van that Elliot blew up the night before. She hacks into the local PD's network and gives Janice the information she wants, before looking over at the Christmas cookies and crying at the lack of normality she has. She receives a text from a colleague stating, "Irish bastard released" and opens a police PDF file regarding this Irish man.

Back in her mother's house where her family is gathered to celebrate Christmas, Dom sees a suspicious looking van parked opposite her street whilst she is walking her dog. She writes down the car license plate. When she is back at her mother's home, she receives a new assignment from Janice, who sends her a picture of Darlene and Elliot in their getaway car and tells her to find them. (“405 Method Not Allowed”)

She goes to Angela's flat, where she finds Darlene. Dom pulls a gun on her, and tells her she should have "kept driving". After demanding Darlene take a seat, Dom calls Janice who tells her to keep Darlene close. She is informed later by Janice that the "higher-ups" only want Elliot, not Darlene to which she responds that she can track him down using Darlene's phone so they "don't need her". When she asks what to do with Darlene, Janice responds, "Kill her." Clearly shocked by this demand, she asks her to repeat the command. Janice then intimidates her and tells her that if she doesn't kill Darlene, she will have to kill her family and all her loved ones. She immediately rushes into action and throws her into the bathtub and pulls a gun to her head. She blames her for ruining her life once again, to which Darlene responds that she is right but that she can fix it, and announces their plan to destroy the Dark Army that will take place that night. Agitated in a high-tension situation, Dom hits Darlene across the face with a gun, knocking her out.

When Darlene wakes up, she tells her that the night they spent together was special to her. Dom tells her that she knows she was just using her, which Darlene denies. Refusing to kill Darlene, Dom demands Darlene to kill her instead, and that she has been thinking of doing it the past two months but she couldn't find the courage to do it. Darlene refuses and time is up - Janice breaks into the apartment with two henchmen. She reassures Dom, telling her that she isn't going to kill her because she is still "far too useful". Instead, she pulls a gun on Darlene because they have deemed her useless and only want Elliot, before Darlene informs her that the phone will be useless as she has wiped it - leaving Darlene too valuable to kill. (“406 Not Acceptable”)

On Christmas Day, Janice has Dom and Darlene tied up in Angela's apartment. She reveals that she knows that Dom pleasures herself to Darlene's interrogation video in the middle of the night, embarrassing Dom in front of Darlene. Janice then reveals a selection of tools, implicating that they are going to be used on Dom and Darlene, before asking a series of questions regarding their relationship. When Darlene refuses to give her brother's location up, Janice stabs Dom in the chest. Darlene is about to help her, when Janice tells her that pulling the knife out of her chest will make her die even faster. Despite this, Dom (who is struggling to breathe on the floor) tells Darlene not to tell Janice Elliot's location. This leads Janice to implicate a call the Dark Army surveillance team outside Trudie's house and threaten the lives of thirteen of her family members that are held hostage. Dom begs and tells Janice not to and with this, Darlene asks for her phone back so she could give up Elliot's location.

They are unable to track down Elliot using his phone location so Janice tries to call the Dark Army surveillance team to tell them to kill Dom's mother, Trudie. There is no answer, however, and Dom tells Janice to check her phone. Janice calls the phone number that had called Dom's phone fourteen times labelled "Lucky Irish Bastard". A man picks up and it is revealed to be the same man that Dom was sent the PDF of a few days ago. He tells Janice, thinking that it's Dom, that the "license plates ... checked out" and he has gotten her family out and is taking them to the safe house. He names himself as Deegan and while Janice is distracted with the phone call, Dom uses the knife still in her chest to slash one of the henchmen in the calf. She uses the gun of the collapsed henchman to shoot the other two, before shooting Janice. Whilst Dom is struggling to breathe, she calls the FBI and tells them that an officer needs immediate assistance. She tells Darlene, who is lightly pressing her wound in order to keep her alive, to leave and help Elliot bring "them" down. (“408 Request Timeout”)

Dom is lying in a hospital bed, having finished an interview with an FBI agent. He tells her that she might end up with a record due to the crimes she committed as a mole for the Dark Army. She realises through the news playing on the TV that Whiterose had been trying to show who she was through the dresses she had shown Dom during her trip to China. She asks the nurse about the IV bag and says she doesn't want any drugs, and that she is going home anyway; she states that she wants to see her family. The FBI agent tells her that they are safe and she is not allowed to know where they are or see them until OPR clears her. She demands to the nurse that she wants to be released though the nurse is reluctant. When she is wheeled out, she tells the nurse she has no one to help her get home safely and she was just planning on taking a cab. The nurse tells her it's against policy due to the fact that she is still technically under anaesthesia and goes to find someone who can help her home.

Once home, she barricades her front door with a dresser. Darlene drops by to pick her up and tells her to run away with her and Elliot, which she refuses. Dom tells Darlene that she wants to stay until she gets cleared by OPR and can see her family. When Darlene says, "You're just going to sit there all alone?" Dom responds, "I'm not alone. I have Alexa, remember?" Darlene then smashes Alexa stating that Alexa isn't a person before demanding that Dom get her toothbrush.

Dom and Darlene are enroute to run away when while Darlene and Elliot are saying goodbye, she enters the motel room and sees Leon sitting on the bed. Shocked, she asks what he's doing there. Leon doesn't recognise her and it takes multiple promptings from Dom to register how they know each other. He then announces that he is no longer with the Dark Army and is there to help "Elliot and his sis".

When they're temporarily stopped at a rest stop, Dom watches Darlene do something on her phone. When Darlene refuses to tell her, she anxiously insists that she tells her immediately. Darlene kisses her and tells her to just wait; they watch while people receive notifications on their phones and read the contents excitedly. Darlene explains that she and Elliot found a way to evenly distribute the contents of Whiterose and his cronies' bank accounts "back to the people" through Ecoin. Dom herself receives a notification and asks her "Everyone got this much?" to which Darlene replies, "Yep." She then explains that it is impossible to reverse the transaction. When Dom argues that "This isn't what justice is supposed to look like", Darlene defends her actions stating that this is "The greatest distribution of wealth in history", comparing their actions to Robin Hood. "If you ask me, this is exactly what justice looks like" and cheers in happiness. Everyone in the park watches as Darlene screams.

At the bookstore in the airport, Irving sees Dom and starts conversation, offering her a signed self-written book. Dom backs away and begs him not to hurt them. Irving states that Janice was "a pain in the ass" and that "they've picked up and skedaddled off to something more important." Irving tells her that the Dark Army don't care about the two of them nor Dom's family. Irving tells her to "take it easy" and leaves.

Dom joins Darlene at the bar and they discuss her encounter with Irving. Dom states that they don't need to run anymore, but Darlene says that they should go anyway because Cisco wanted to go to Budapest and they'd always planned to go together. Dom states that she doesn't want to leave, not now that she doesn't need to. Darlene tries to persuade her, but she states "You don't need me to come with you." Dom apologises despite Darlene's best efforts and tells her to send her a postcard. She gives Darlene the number of a friend in US Cyber Command, for when she's "ready to grow up". Watching Darlene's back walk away, she cries.

Regretting her decision, Dom runs back to board the plane in time. (“410 Gone”)
