Character analysis
Leah
in DNA by Dennis Kelly
Leah is a key character in Dennis Kelly's DNA, a gripping ensemble drama about a group of teenagers who try to hide the accidental death of a classmate. From the beginning, Leah is characterized by her anxious, compulsive monologues directed at Phil, who mostly remains silent beside her. These one-sided dialogues—covering topics from the nature of happiness to chimpanzee ethics—unveil a sharp, restless mind grappling with guilt, moral confusion, and a deep need for connection. Her tendency to ramble serves as both a coping strategy and a plea for recognition that Phil consistently denies.
Leah's journey reflects a painful moral awakening. Initially involved in the group's deception, she becomes increasingly unsettled as Phil's cold, pragmatic leadership intensifies—culminating in his choice to scapegoat Brian and to silence the innocent Adam for good. While others go along with Phil's ruthless approach, Leah is the only one who consistently raises ethical objections, asserting that their actions are wrong. Unfortunately, her dissent does not alter the group's fate.
By the end of the play, Leah has completely withdrawn from the group—reportedly choosing to align with a different social circle. This quiet exit symbolizes both an escape and a defeat: she couldn't save Adam or reform Phil, but she refused to stay complicit. Her departure highlights Kelly's theme that having moral awareness, without the power or will to take decisive action, may lead to little more than self-preservation. Leah ultimately serves as the play's conscience—articulate, tormented, and tragically powerless.
Who they are
Leah serves as the moral voice of DNA, a teenager whose intelligence and emotional intensity distinguish her from the group. She is introduced in the play's earliest scenes next to Phil in a field, filling the silence with urgent, searching monologues — on happiness, on the nature of human beings, on chimpanzees and their capacity for violence. These speeches reveal a mind that cannot stop interrogating the world, and a heart that desperately needs someone to explore it alongside her. She is perceptive enough to see what is happening around her, sensitive enough to be wounded by it, and, crucially, not powerful enough to stop it. Kelly positions her as the play's conscience: articulate, restless, and ultimately isolated by the very qualities that make her sympathetic.
Arc & motivation
Leah starts as an anxious but compliant member of the group, drawn into the collective deception surrounding the apparent death of Adam. Her initial rationalisation — "We didn't do anything wrong. We were just... we were just there." — indicates she is trying, like the others, to manage guilt through denial. However, as her peers grow more comfortable with the cover-up, Leah becomes increasingly uneasy. Her monologues destabilise, cycling between self-justification and self-accusation. Her core motivation is dual and contradictory: she seeks Phil's approval and companionship, yet her ethical judgements cannot be suppressed even when expressing them jeopardises that connection. As Phil's decisions escalate from concealment to scapegoating to the silencing of Adam, Leah's dissent intensifies. Her departure at the end of the play signals not a triumphant moral stand but rather a quiet collapse of endurance — she leaves because staying has become intolerable, not because leaving will change anything.
Key moments
- The opening field scenes establish Leah's dynamic with Phil immediately. Her line "What are you doing? What are you eating? Stop eating." encapsulates her helplessness — she demands attention, Phil ignores her, she keeps talking regardless.
- Her acknowledgment of collective guilt — "He's dead. We killed him. We have to deal with that." — is one of the few moments in the play where someone clearly names the moral reality. The lack of response to this statement is devastating.
- Adam's return acts as a pivot in Leah's arc. Rather than bring resolution, it introduces deeper horror: Phil decides that Adam must be silenced permanently to protect the group's narrative. Leah's protests here represent her most direct and yet futile attempts.
- Her challenge to Phil — "You don't feel anything, do you? Nothing. You're just... nothing." — is her closest move towards openly breaking from him. This line serves as an accusation, a plea, and a farewell compressed into a few words.
- Her disappearance, narrated through Jan and Mark's detached account, confirms that Leah has left the group. Her absence contrasts sharply with the group's continuity. The casualness of this report serves as an indictment.
Relationships in depth
Phil acts as the gravitational center of Leah's world, which constitutes her tragedy. Each monologue targets him; every pause anticipates his response. His silence is not neutral but a form of dominance that keeps Leah in a state of constant seeking and unease. When she finally asserts he feels nothing, she articulates something she has long understood but could not accept.
Adam stands as Leah's moral test. "He was our friend. He was our friend and we left him." Her guilt regarding Adam is genuine and recurring. His elimination by Phil — a death the group chooses rather than stumbles into — marks the moment the situation becomes irredeemable for her.
Brian's scapegoating horrifies Leah as it highlights the group's readiness to sacrifice the vulnerable for their convenience. His psychological unraveling reflects her own growing instability.
Cathy's casual enthusiasm for violence sharpens the focus on Leah's anguish. While Leah agonises, Cathy takes action. This contrast suggests that having a conscience, in this world, is a disadvantage.
Jan and Mark, as chorus figures, frame Leah's story from an external viewpoint. Their indifferent report of her departure underscores how little her moral stance has impacted the group's survival or self-image.
Connected characters
- Phil
Phil is Leah's closest companion and the central relationship of her arc. She directs all her monologues at him, craving validation he never gives. His silence is a form of control that both frustrates and binds her. When Phil's decisions turn lethal, Leah's inability to reach or change him defines her ultimate failure and motivates her eventual disappearance.
- Adam
Adam's fate is the moral crux of Leah's journey. His return—alive—should be a relief, but Phil's decision to eliminate him to protect the group horrifies Leah. She protests but cannot prevent it. Adam represents the innocent victim whose death crystallises Leah's guilt and pushes her to finally break from the group.
- Brian
Brian is used by Phil as a scapegoat, framing an innocent man. Leah witnesses this manipulation and objects, recognising the cruelty of sacrificing a vulnerable member of their own group. Brian's psychological deterioration mirrors the moral rot Leah is desperate to name and resist.
- Cathy
Cathy's cheerful willingness to carry out Phil's darkest instructions—including violence—stands in stark contrast to Leah's conscience-driven hesitation. Cathy embodies the group's capacity for casual brutality, making Leah's moral isolation all the more acute.
- Jan
Jan, alongside Mark, functions as a chorus figure who reports events to the audience. Their detached narration of Leah's eventual absence underlines how quickly the group moves on, highlighting Leah's expendability despite her moral centrality.
- Mark
Like Jan, Mark delivers expository updates that frame Leah's story from the outside. His matter-of-fact tone when reporting her departure reinforces the group's indifference to her ethical stand.
Key quotes
“He was our friend. He was our friend and we left him.”
member of the peer group (likely Leah or Jan/Mark)
Analysis
This poignant line is from DNA by Dennis Kelly, a brief yet impactful play aimed at young audiences that delves into themes of guilt, complicity, and moral cowardice among a group of teenagers. The quote is delivered by one of the group members following a horrific incident: the gang, thinking they have unintentionally caused the death of Adam, a classmate they bullied, conspires to hide their involvement instead of confronting the fallout. The line reflects the heavy moral burden of their shared betrayal — Adam wasn't just a peer; he was a friend, making their abandonment even more unforgivable. The repetition of "He was our friend" captures the characters' painful realization of their actions. Thematically, the quote is crucial to Kelly's examination of how ordinary young people can perpetrate extraordinary cruelty through groupthink, silence, and the instinct for self-preservation. It also prompts reflection on loyalty, responsibility, and whether guilt can persist in a group that has collectively opted for denial. This line serves as a moral compass in a play that risks normalizing the chilling pragmatism of its characters.
“We didn't do anything wrong. We were just... we were just there.”
Phil or Leah (one of the teenage group members)
Analysis
This haunting line is from DNA by Dennis Kelly, a short yet powerful British play often included in secondary school curricula. One of the teenage characters—most likely Phil or Leah—utters the quote in the context of the group's shared guilt after the accidental death of their peer Adam and the cover-up that followed. The phrase "We were just... there" highlights the moral paralysis central to the play: the characters try to distance themselves from responsibility by focusing on their passive presence instead of their active involvement. Kelly uses this moment to examine how complicity among bystanders operates within group dynamics, suggesting that inaction can also be a moral choice. The ellipsis and the repetition of "we were just... we were just there" reflect the psychological fragmentation of guilt, as the speaker grapples with a defense they don't entirely believe. Thematically, this line captures the play's main concern: the decline of individual conscience under peer pressure and the dangerous notion that silence or inaction can be equated with innocence. It strongly resonates with real-world conversations about mob mentality, teenage social hierarchies, and moral responsibility.

Analysis
This haunting line comes from DNA by Dennis Kelly, a short but powerful British play aimed at young audiences that delves into themes of collective guilt, moral responsibility, and the psychology of group dynamics. The quote is spoken by the teenage gang after they think they have accidentally caused the death of Adam, a peer they bullied and left for dead. Likely voiced by one of the more pragmatic or dominant members of the group, the line cuts to the core of the play's main tension: the characters must now face the consequences of their actions together. Instead of leading to real remorse or confession, this acknowledgment of guilt triggers a cover-up, showing how moral awareness can be distorted into self-preservation. Thematically, the quote captures Kelly's examination of mob mentality, the fading of individual conscience in a group, and how easily young people can justify their wrongdoings. It compels both the characters and the audience to grapple with the burden of shared responsibility — and the unsettling question of what "dealing with it" truly involves.
“What are you doing? What are you eating? Stop eating.”
Leah
Analysis
This quote is from DNA by Dennis Kelly, a brief yet powerful British play from 2008 that is often included in secondary school curricula. The line features Kelly's signature fragmented, staccato dialogue style—short, overlapping, and interrupted speech that reflects the chaotic moral landscape of the teenage characters. Leah delivers the quote as she bombards Phil, her mostly quiet partner, with anxious, rapid-fire questions and commands. Phil's tendency to eat during their interactions serves as a striking dramatic symbol: his calm consumption signifies detachment, control, and a troubling indifference to the rising moral crisis facing their group. Leah's frantic efforts to elicit a response from Phil—even over something as minor as eating—highlight her emotional fragility and her longing for human connection and validation. This moment thematically captures one of the play's key issues: the peril of moral passivity. Phil's silence and lack of action prove to be more harmful than the openly cruel behavior of the other characters, prompting reflection on complicity, leadership, and conscience.
“You don't feel anything, do you? Nothing. You're just... nothing.”
Leah
Analysis
This biting accusation comes from DNA by Dennis Kelly, a brief but powerful British play aimed at young audiences that delves into mob mentality, moral emptiness, and the troubling appeal of passive leadership. The remark is directed at Phil, the unnervingly quiet and emotionally detached co-leader of the teenage gang, likely spoken by Leah, his anxious and talkative friend who desperately craves connection and a reaction from him throughout the play. Leah's monologues are mostly one-sided dialogues with Phil, who seldom replies, and this outburst highlights her increasing fear of his complete emotional numbness. Thematically, the quote taps into the play's core issue: the lack of empathy as a precursor to evil. Phil's emptiness isn't just personal indifference — it allows the group's escalating moral transgressions, including covering up what they think is a murder. Kelly uses Phil's blankness as a mirror reflecting the group and, by extension, the audience, prompting the question of whether moral sentiment is essential for being human. The line also hints at Phil's unsettling effectiveness as a leader precisely because he feels nothing.
“People are happier, Phil. Did you know that? There are studies. People are happier since this happened.”
Leah
Analysis
This quote is from DNA by Dennis Kelly, a brief yet impactful play aimed at young audiences. It delves into the moral and psychological consequences faced by a group of teenagers who try to cover up the accidental death of one of their peers. Leah, an emotionally charged and restless character, delivers this line to Phil, her mostly silent companion who she constantly engages throughout the play. This moment occurs during one of the play's recurring scenes where Leah monologues to the indifferent Phil, referencing supposed scientific studies to argue that their terrible secret — and perhaps general cruelty and complicity — has oddly made those around them happier. The quote is thematically powerful: it challenges the audience to grapple with the unsettling notion that wrongdoing, denial, and the suppression of truth can exist alongside — or even foster — social happiness. Kelly uses Leah's pseudo-intellectual arguments to examine mob mentality, moral disengagement, and the unsettling human ability to normalize horrific acts. The line captures the play's central dark irony: happiness and horror can coexist, and communities may thrive on deception.
