Key Themes
Theme: Class and Inequality
Class is the dominant theme of Blood Brothers. Every character, event, and structural choice in the play connects to Russell’s argument that the British class system is unjust and destructive. The twins are his central device: identical DNA, different classes, tragically different outcomes. Russell uses them to demonstrate that a person’s life chances are determined not by ability or character but by the wealth of the family they are born into.
The class divide is visible in everything: the Johnstone council estate versus the Lyons private house; Mickey’s dialect versus Eddie’s standard English; Mickey’s factory job versus Eddie’s university degree; Mickey’s prison sentence versus Eddie’s council seat. Russell accumulates these contrasts relentlessly, building an overwhelming case that class is a system of inherited privilege and inherited disadvantage.
The Narrator’s closing question — “And do we blame superstition for what came to pass? Or could it be what we, the English, have come to know as class?” — is Russell’s thesis statement. The rhetorical question makes the answer obvious: class, not fate, caused the tragedy. By saying “we, the English,” Russell implicates his audience as participants in the system.
Theme: Nature versus Nurture
The nature versus nurture debate is embedded in the play’s premise. If the twins share identical DNA, then any differences in their lives must be caused by environment — by nurture. Russell’s answer is unambiguous: nurture (class, money, education) determines everything.
This is not just a theoretical argument. Russell grounds it in specific, observable differences. Mickey’s language is shaped by his environment: “Gis a sweet” is working-class Liverpudlian. Eddie’s language is shaped by his: “smashing” and “fantastic” are middle-class. Mickey’s opportunities are limited by his school and postcode. Eddie’s are expanded by his parents’ wealth. The play is Russell’s controlled experiment, and the results are devastating.
Language: Mickey speaks in dialect; Eddie speaks in standard English. Both are equally articulate, but society values Eddie’s speech over Mickey’s.
Education: Eddie attends private school and university. Mickey attends a comprehensive and leaves at sixteen. The education gap creates the opportunity gap.
Employment: Eddie becomes a councillor. Mickey becomes unemployed. Identical ability, different outcomes.
Crime: Mickey turns to crime out of desperation. Eddie never faces the circumstances that would drive someone to crime. Russell argues that crime is a product of poverty, not character.
Theme: Superstition and Fate
Superstition runs through Blood Brothers like a thread. Mrs Lyons’ invented curse (“they shall both immediately die”), the Narrator’s warnings (“shoes upon the table,” “the devil’s got your number”), and Mrs Johnstone’s deep-seated fear of bad luck all create an atmosphere of inevitable doom. The audience is constantly asked: is the tragedy caused by supernatural fate, or by social forces?
Russell’s answer, delivered through the Narrator’s closing question, is that class — not superstition — is the real cause. But Russell deliberately leaves ambiguity. The twins do die when the truth is revealed, exactly as the curse predicted. The superstition works as a dramatic device that keeps the audience in suspense while Russell builds his political argument underneath.
Superstition in Blood Brothers serves two functions: it is a plot mechanism (keeping the secret) and a thematic red herring (distracting from class as the real cause). Russell uses superstition to engage the audience emotionally, then challenges them intellectually with the closing question.
Theme: Motherhood
Russell presents two models of motherhood through Mrs Johnstone and Mrs Lyons. Mrs Johnstone is a natural, instinctive mother — warm, loving, and emotionally present, despite her poverty. Mrs Lyons is an anxious, possessive mother — she loves Edward but smothers him with overprotection driven by guilt and fear. Russell suggests that motherhood is shaped by class: Mrs Johnstone’s poverty forces her to give up a child, while Mrs Lyons’ wealth allows her to take one.
The play also explores the limitations placed on working-class mothers. Mrs Johnstone’s husband abandons her. She has no financial support. She cannot afford legal advice or childcare. Russell shows that the system fails working-class mothers at every turn, then judges them for the impossible choices they are forced to make.
Theme: Violence
Violence escalates throughout the play, from innocent childhood games to fatal adult confrontation. The children play with toy guns. Sammy burns the school down. Sammy commits armed robbery. Mickey takes a real gun to the Town Hall. The police shoot Mickey dead. Russell structures this escalation deliberately, showing how violence in deprived communities grows from play to reality when opportunity is absent.
Childhood: Toy guns and war games — innocent play that normalises violence.
Adolescence: Sammy burning the school down — real destruction driven by boredom and lack of opportunity.
Adulthood: Armed robbery, prison, the final shooting — violence as the inevitable product of poverty, unemployment, and desperation.
Russell shows that violence is not inherent to working-class people — it is produced by a system that denies them alternatives. Eddie, with identical genes, never commits a violent act. The difference is class, not character.
The Narrator’s Role in Developing Themes
The Narrator ties all the themes together. He represents superstition (through his ominous songs), fate (through his foreknowledge), and class (through his closing question). His presence on stage is a constant reminder that the characters are not in control of their own destinies. Whether the Narrator represents a supernatural force or the social system itself, his function is the same: to show that the outcome was always inevitable.
