Self-reinvention and identity
The Girl on the TrainSelf-reinvention and identity are presented not as a settled transformation but as an ongoing effort to name, perform, and sometimes escape the self. Megan Hipwell imagines that she can choose who to become next; Rachel Watson, by contrast, struggles with a sense that drinking and other people’s perceptions have made her into someone she barely recognizes.
Megan’s Chosen Selves
After quitting her job, Megan feels newly free and starts imagining practical alternatives: a photography course, a market stall selling jewellery, or learning to cook. She expects Scott Hipwell to be annoyed only briefly and believes she can make things right with him. Her plans make reinvention feel like an open field of possible lives rather than a single dramatic change.
That possibility has a history. A teacher once called Megan a “mistress of self-reinvention,” a phrase she says she came to like. She describes herself through successive roles—“Runaway, lover, wife, waitress, gallery manager, nanny”—and treats the question of who to be tomorrow as still open. The list turns identity into a story repeatedly revised through work, intimacy, and circumstance. Yet the freedom of that story also carries uncertainty: reinvention means that no one role, including wife or gallery manager, has to be final.
Rachel’s Damaged Self-Image
Rachel’s experience is less chosen. She believes she is no longer desirable and imagines that the effects of drinking and sleeplessness are visible in her puffy face, her body, and the way she moves. A stranger’s glance on the train seems to confirm her fear that others can read her damage, though the distaste she attributes to him remains her interpretation rather than established fact.
That self-consciousness has a social counterpart. Rachel overhears Cathy worrying that she is lonely and asking whether there might be someone at work or the rugby club for her; Cathy’s boyfriend dismisses the idea with a cruel remark about who would be desperate enough. The exchange gives Rachel’s fear of being undesirable an external echo, while also showing how casually other people make her into a type. Her identity is shaped both by her own harsh appraisal and by judgments she hears or believes she sees in others.
Improvisation and Division
Rachel’s attempt to leave Anna Watson’s nanny job shows another, more immediate kind of reinvention. In the awkwardness of sitting with Anna, the baby, and Tom Watson, she feels that she is intruding; the words announcing that she has found another job come out before she has planned them. Anna does not ask what the job is, sparing Rachel the need to invent a convincing explanation. Unlike Megan’s imagined options, Rachel’s new identity in this moment is an improvised cover for discomfort.
Alcohol further divides Rachel’s sense of self. After contacting Scott with a lie to persuade him to talk, she contrasts a clear-headed version of herself, which had decided to accept that her part in the story was over, with “Drunk Rachel,” who sees no consequences and exists only in the moment. That persona can be expansive and optimistic or consumed by hate. Her shame afterward, and her repeated attempts to write and delete an apology to Tom, expose the cost of treating the drunken self as both separate from and answerable to the person she wants to be.
Narrative Significance
Together, the two trajectories make identity unstable in different ways. Megan’s list of roles presents the self as revisable, with tomorrow still available for reinvention; Rachel’s account reveals how that freedom can fail when social humiliation, self-loathing, and alcohol shape the story a person tells about herself. The contrast is not simply between a confident and a damaged woman: Megan’s many roles also imply impermanence, while Rachel’s divided selves show how urgently she wants to believe that her actions belong to someone other than her. In both cases, identity emerges through narration—through names for the self, roles adopted or abandoned, and stories that can be revised but not made consequence-free.
