Scarlet O’Bannon

Scarlet O’Bannon is a Federal Bureau of Investigation agent whose investigation into organized crime becomes a test of whether the institution she serves can still be trusted. Methodical and outwardly controlled, she begins by insisting on professional distance from Cormac MacKay, an Irish mobster and confidential informant. As evidence points toward corruption inside the agency, however, her work and her personal loyalties become difficult to separate. She continues investigating, helps defeat Mickey MacFarland, and ends the story engaged to Cormac.

Identity and Investigative Method

Scarlet’s introduction establishes a professional persona she has spent years cultivating. At work, she sits straight, maintains a composed manner, and takes responsibility for examining the details of an overnight review of surveillance footage related to a drug deal. Although colleagues had advised her to leave that work to newer agents, she believes that close attention matters: a detail overlooked by someone else may be the one that clarifies a case. Her approach is not simply diligence for its own sake; it makes her willing to do investigative work personally, even when fatigue and a headache would make delegation easier.

Her supervisor, Max Smithson, knows that Cormac has asked to meet and presses her to take the opportunity. He suggests that her judgment may be clouded by attraction, but Scarlet rejects that interpretation and tells herself that Cormac is a criminal who provides information about rivals while protecting his own people. The tension in this denial is evident in how carefully she manages their contact. She answers him as Agent O’Bannon, keeps her voice deliberately unemotional, and objects when he uses her familiar nickname. Her professionalism is real, but it cannot by itself settle the question of how far her feelings have already moved beyond it.

Cormac MacKay and the Limits of Procedure

Scarlet’s connection with Cormac starts within the formal language of informant work: he says he has information, and she expects him to explain it. Their exchanges quickly reveal a more personal familiarity beneath that arrangement. Cormac calls her Scar, while she insists on her official title; his teasing and her corrections become a recurring contest over whether their relationship will remain confined to their professional roles. Scarlet’s effort to keep him at a distance is complicated by her awareness that she is not entirely detached from him.

When violence at The Leprechaun forces them into the street, Scarlet immediately re-enters Federal Bureau of Investigation procedure. She checks that their attackers have fled and reaches for her phone to report the assault, anticipating that agents will secure the location, look for clues, and review surveillance footage. Cormac intervenes before she can simply follow that plan. He argues that Mickey could not have moved against his father without assistance: his father was intelligent, while Mickey was not, and the apparent removal of some of Cormac’s men to California helped clear the way for the takeover. Scarlet understands the theory but resists treating it as established fact. To her, Cormac’s world and her professional responsibilities are distinct; rules and evidence matter precisely because suspicion alone cannot prove who is involved.

That distinction becomes harder to maintain as the investigation develops. When Cormac opens a car trunk and Scarlet sees blue jackets marked with the letters identifying the Federal Bureau of Investigation, along with familiar agency-issued clothing and equipment, the possibility of internal involvement ceases to be an abstract suspicion. The discovery overwhelms her. It does not identify every person involved, but it gives material form to the fear that the agency itself has been compromised. The familiar markers of her work, normally signs of authority and belonging, now point toward betrayal.

Investigating Max Smithson

Scarlet turns her investigative attention toward Max after gathering reasons to distrust him. Over six days, she meets with agents and researches personnel who appear suspicious, with Max becoming a central focus. She finds that he owns a yacht, an apartment, and a house in California despite having no offices there; his brother works lower down in the Federal Bureau of Investigation, and Max has spent his holiday time in California. She also discovers that he owns a string of local laundromats, apparently without a clear purchase history. These circumstances deepen her suspicion, but the narrative does not present them as proof of guilt on their own.

More than a month later, Scarlet and her father have additional grounds for believing Max works for Mickey: witnesses have seen the two men together, and agents in California had already harbored suspicions. Even so, they do not have enough evidence to bring Max in. Arresting him could alert Mickey without advancing the case. Scarlet therefore continues to perform the outward role of an agent leading an investigation into Mickey’s mob while privately accounting for the possibility that her supervisor is reporting to a superior connected to the operation. Her restraint is tactical as well as procedural: exposing suspicion too soon could destroy the chance to gather more useful evidence.

Mickey MacFarland and the Ballroom Bust

The threat Scarlet investigates extends beyond a single mob takeover. Mickey’s organization has become involved in prostitution, hard drugs, and murder, while the suspected links to corrupt agents make ordinary recourse to the Federal Bureau of Investigation dangerous. During the effort to locate the captives, Flint studies a photograph and notices towers reflected in a mirror; their arrangement and angle suggest the ballroom. The inference gives the search a concrete destination without resolving every uncertainty about who is supporting Mickey.

Scarlet and Moira MacKay are held by Mickey. The circumstances are especially painful because the intended plan had been to use Moira as bait only with her knowledge and while keeping her safe; what happens instead is not that controlled arrangement. Cormac reaches Scarlet while she is captive and promises that the three of them will get out that night. His presence is reckless in her judgment, and she tells him so, but his assurance also marks how much their relationship has changed: he has come into danger rather than remain outside it. Scarlet’s anger and fear do not erase the trust between them, just as that trust does not make her stop challenging his decisions.

After what becomes known as The Ballroom Bust, Scarlet and her father share the substantial work of completing paperwork, conducting interviews, and corroborating evidence. The operation’s consequences reach beyond Mickey himself. Mickey receives life sentences for multiple murders, his men are imprisoned or tried, and the corrupt agents are removed; Scarlet learns that one of those agents was a serial rapist and killer. The result is a professional victory, but one earned in the wake of evidence that the institution had been penetrated from within.

Family, Change, and Ending

Scarlet’s relationship with her father also changes through the investigation. They work together on the aftermath of the Ballroom Bust, and he tells her he is proud of her, including for achievements he should have acknowledged earlier. He also tells her that he does not blame her and regrets ever suggesting otherwise. The confession gives their shared work an emotional dimension: the case does not merely put them on the same side of an investigation; it creates a moment in which past hurt can be named and his earlier judgment withdrawn. When her father later arrives where she is staying with Cormac, Scarlet quickly comes to his defense, objecting to his being treated like a criminal.

Scarlet’s feelings for Cormac likewise become harder to deny as the danger recedes. She later recognizes that the two weeks they spent on the run, the time she spent with him and Moira, and the years of their prior dealings have made her fall in love with him. What she once framed as a professional boundary cannot contain the relationship that has formed through risk, argument, and reliance. The romance does not replace her investigative identity; she remains Agent O’Bannon even at the moment when Cormac asks her to marry him.

The proposal takes place at The Leprechaun, the setting associated with the beginning of their story. By then the bar has changed hands twice in a year and become a place filled with families, couples, and laughter. Cormac is there at the booth where the relationship began, his appearance no longer marked by the same effort to survive the cold. He asks Scarlet to marry him, and she answers by embracing and kissing him rather than speaking. Her ending joins the two strands that have defined her arc: she retains her public identity as an agent while accepting a future with the informant who became her partner and beloved.
