The “Just Keep Swimming” Mantra: Resilience and Healing in It Ends with Us
What Is the “Just Keep Swimming” Mantra?
The phrase “just keep swimming” originates in Finding Nemo, spoken by the relentlessly optimistic blue tang fish Dory. In It Ends with Us, it becomes a private motif between Lily Bloom and Atlas Corrigan, evolving from a shared childhood comfort into a personal philosophy for enduring hardship and, eventually, a signal that the time for mere survival is over. This analysis traces the mantra’s recurring appearances, the ways its meaning shifts across Lily’s life, and its deep ties to key characters and themes.
Origins: A Cartoon, a Sick Boy, and a Whispered Promise
The mantra first appears in Chapter Eleven. Lily is fifteen, and Atlas—the homeless boy she has been secretly sheltering—has fallen violently ill. After a long night of caring for him, she lets him stay at her house while her mother is at work. To pass the time, they watch Finding Nemo together. When Dory tells a defeated Marlin “When life gets you down do you wanna know what you’ve gotta do?… Just keep swimming…,” Atlas grabs Lily’s hand and squeezes it. Lily instinctively whispers the phrase back to him: “Just keep swimming.”
In that moment, the words are a simple act of comfort. Atlas is sick, exhausted, and living with the trauma of homelessness; Lily is helping him stay afloat literally and emotionally. The cartoon line becomes their secret shorthand for perseverance—a promise to keep one another going.
From Childhood Comfort to a Mantra of Survival
After Atlas is beaten by Lily’s father and disappears, the mantra detaches from its original source of shared strength and becomes a lonely survival tool. In the diary entries that make up Chapter Seventeen, Lily writes about the aftermath. She confides to Ellen DeGeneres that she cries herself to sleep every night and whispers, “Just keep swimming.” But she immediately complicates the image: “it gets really hard to swim when you feel like you’re anchored in the water.”
This shift is critical. The mantra once signified an active, mutual effort to move forward; now it describes a desperate attempt not to drown in grief and fear. Lily admits she will “keep pretending to be okay. I’ll keep pretending to swim, when really all I’m doing is floating. Barely keeping my head above water.” The metaphor reveals that the mantra can mask a dangerous passivity: merely going through the motions while sinking inside. For the first time, the phrase carries the weight of the cycle of domestic abuse and rationalization: survivors often keep moving to survive, even when that movement is more illusion than action.
The Ellen DeGeneres Book: A Tangible Return of the Mantra
Years later, the mantra resurfaces as a physical object. In Chapter Sixteen, Atlas walks into Lily’s flower shop and hands her a late birthday present: an autographed copy of Ellen DeGeneres’s book Seriously… I’m Kidding. The inscription reads, “Lily, Atlas says just keep swimming.” The gift proves that Atlas has held onto their private language all these years. The phrase now bridges time and loss, becoming a token of an unbroken bond.
The choice of Ellen DeGeneres is no accident. Lily’s teenage diaries are addressed to Ellen, the imagined confidante who received all her secrets about Atlas. By having Ellen herself echo the mantra, Atlas weaves their past into the present. The book sits in Lily’s closet with her journals, a physical reminder that the mantra—and the love it represents—has not been forgotten.
Lily’s Adult Struggle: Pretending to Swim While Drowning
As an adult, Lily does not explicitly repeat the mantra during her marriage to Ryle Kincaid, but the psychological pattern she set in her teenage years persists. Her earlier confession of “pretending to swim” while really only floating echoes through her rationalizations of Ryle’s abuse. She tries to convince herself that the good moments outweigh the violent ones, mirroring the survival tactic of her mother, who endured decades of abuse in silence.
The mantra’s evolution here is subtle. It no longer functions as a buoy thrown between two loving people; instead, it has become an internal mechanism that blurs the line between resilience and self-deception. The connection to the impact of childhood trauma is strong: Lily learned early that one must keep going even when every instinct screams to stop, and that lesson nearly traps her in the same cycle her mother suffered.
Naming Emerson Dory: The Mantra Becomes a Legacy
The mantra takes its most hopeful turn in the Epilogue. After giving birth to her daughter and making the wrenching decision to divorce Ryle, Lily chooses the middle name Dory. She does not announce it publicly; it is a private homage. When she bumps into Atlas on a Boston street, she rushes after him to share the news: “I forgot to tell you Emerson’s middle name.… It’s Dory.”
This act transforms the mantra from a whispered survival trick into a lasting legacy. Lily does not want her daughter to merely “just keep swimming” through abuse. By giving the name Dory, she reclaims the phrase as a symbol of hope, not endurance alone. It also reconnects her to Atlas, who instantly grasps the meaning. The name links the new generation to the old promise, tying together Lily’s past and her future.
Reaching the Shore: The Mantra’s Final Transformation
The resolution of the motif comes in the Epilogue’s closing lines. After Lily tells Atlas she is ready to be with him, he pulls her close. In a whisper, he says, “You can stop swimming now, Lily. We finally reached the shore.”
The shift from “just keep swimming” to “you can stop swimming” is the mantra’s final transformation. The shore symbolizes safety, the end of a long and painful journey. Lily no longer needs to fight merely to stay afloat; she has broken the cycle of abuse, protected her daughter, and found a partner who shares the language of her survival. The mantra’s arc—from a cartoon line, to a survival tactic, to a declaration of arrival—mirrors the novel’s central arc of breaking free from generational patterns.
Character and Theme Connections
The mantra is primarily carried by Lily and Atlas, but it also illuminates surrounding characters. Lily’s mother, Jenny Bloom, never speaks the phrase, yet she has lived its logic for years—enduring abuse and “swimming” in place because she saw no shore. The difference, as the novel makes clear, is that Lily finally decides to stop swimming in that destructive direction. The mantra thus deepens the theme of the duality of love and pain: love can be the very thing that makes swimming possible, but also the current that drags someone under. Lily’s love for Atlas was a lifeline, while her love for Ryle kept her treading water in a dangerous sea.
The mantra also relates to female support networks and resilience. Allysa, as a friend, becomes part of Lily’s “shore team,” helping her see that she does not have to swim alone. And in the end, Lily’s decision to name her daughter Dory emphasizes that the next generation will inherit hope, not trauma.
