“We’re Here. Right Now: THE RESERVOIR’s Hard-Won Grace”

Jake Brasch’s “The Reservoir,” now playing at Atlantic Theater Company, operates through counterpoint: addiction and dementia, comedy and grief, the impulse to fix and the necessity of letting go. Josh (Noah Galvin), a 20-something alcoholic fresh from a Florida rehab disaster, returns to Denver convinced he can save his four aging grandparents from cognitive decline through sheer force of will—spinach, aerobics classes, Hebrew lessons, anything to build their “Cognitive Reserve” and keep the rivers of memory flowing. But the play’s central revelation arrives slowly, tenderly: Josh isn’t rescuing them; they’re rescuing him. Director Shelley Butler stages the action inside what Brasch calls Josh’s “Mind Palace,” with the grandparents (Mary Beth Peil, Chip Zien, Caroline Aaron, Peter Maloney) present throughout as both real people and Greek chorus, enacting Josh’s scattered thoughts, embodying his metaphors, witnessing his spiral and his slow climb toward grace. What emerges is a theatrically inventive, emotionally rigorous meditation on memory, recovery, and mortality that earns its power through Logos (the intellectual architecture of addiction and Alzheimer’s science), Ethos (Brasch’s autobiographical authenticity as a sober Colorado artist), and Pathos (performances that ground theatrical conceits in achingly human truth). This is a play about learning that you can’t fix everything—and discovering what becomes possible when you finally stop trying.

Brasch doesn’t condescend to his audience by oversimplifying the science. We learn alongside Josh as he devours books at the Denver bookstore where his exasperated boss Hugo (Matthew Saldívar) watches him shelve by smell rather than alphabet. The play introduces us to Dr. Yaakov Stern’s actual Cognitive Reserve Theory—the concept that education, curiosity, diet, sleep, and exercise build neural pathways that help brains work around damage from Alzheimer’s or addiction. Josh seizes on this like gospel: if he can just increase his grandparents’ reserve through spinach consumption and senior aerobics at the JCC, maybe he can stop the rivers of memory from running into plaques, maybe he can redirect the flow, maybe he can build reservoirs where nothing is lost.

The theatrical brilliance is that Brasch shows us both the genuine insight and the delusion. Josh IS right that these factors matter. The grandparents DO enact his metaphors—literally becoming the “river of thought” with flowing arms, slamming into cognitive plaques, finding new pathways around the blockages. But he’s catastrophically wrong about his power to fix anything. The play’s central intellectual paradox arrives in Act Two when Beverly reveals what Josh missed in his frantic research: “The higher the reserve, the sharper the fall.” Build up your cognitive strength through a lifetime of curiosity and health, and yes, you stay lucid longer—but when decline comes, it comes fast. “So is it even worth it?” Josh asks. Beverly’s answer defines the play: “Of course it is. We’re here. Right now.”

This isn’t a play that skims surfaces or trades in easy metaphors. It trusts audiences to hold complexity: that Josh’s obsessive project is simultaneously loving and narcissistic, scientifically grounded and emotionally evasive, genuinely helpful and utterly beside the point. The Logos operates on multiple levels—we understand addiction’s broken thinking, dementia’s erasure, and how both involve rivers that can’t be controlled, only accepted.

Brasch grounds this play in lived experience. The script is dedicated to his grandparents, “and more specifically, my grandma b, who would have requested a paper copy of this play to litter with hilarious, scathing, and insightful notes in red colored pencil.” He identifies himself as a sober artist from Colorado, and the play vibrates with autobiographical truth—not just the broad strokes of addiction and recovery, but the specific textures: the shame of missing a grandmother’s funeral during a blackout, the desperate magical thinking that research can prevent loss, the way early sobriety makes you both hyperaware and unable to focus, the bizarre comedy of getting kicked out of rehab for fermenting grapefruit juice in the boiler room.

The grandparents aren’t generic elderly figures but sharply drawn individuals: Beverly the no-bullshit Jewish electrical engineer and recovering alcoholic who attends senior aerobics at the JCC; Shrimpy the Brooklyn jokester studying for his second bar mitzvah at 83; Hank the conservative Nebraskan evangelical who drinks Budweiser and won’t call it drinking; Irene the sweet Midwestern church pianist whose house always smelled like Christmas cookies and who slips away singing “O Come All Ye Faithful” at lunch. These aren’t types—they’re people, recognizable in their contradictions and specificity.

The play earns its authority through this particularity. As someone who views theater through a psychological lens, and who watched my own mother die from complications of dementia, I recognized both the clinical accuracy and the emotional truth of what Brasch depicts. The compare/contrast between Josh’s alcohol-damaged cognition and his grandparents’ Alzheimer’s-related decline isn’t glib—it illuminates how both involve memory loss, confusion, shame, and the terrifying sense of losing yourself. The play understands that Josh and his grandmother Irene are, in some fundamental way, in the same place: “Eyes glazed over. Lost to the world. Trying to remember who we are. Detached? Demented? Broken?”

This credibility allows audiences to connect not just intellectually but viscerally. We’ve all watched someone slip away—to age, to addiction, to illness. We’ve all tried to fix what can’t be fixed. We’ve all learned, or need to learn, how to let go.

The theatrical conceits could easily become empty cleverness, but the Atlantic production anchors every moment in human truth through performances that understand the assignment: make us feel what Josh feels, what his grandparents endure, what recovery costs. Noah Galvin gives Josh exactly the maddening, yet charming quality Brasch specifies—a young man who “copes through humor, but also evades through humor,” whose hyperverbal self-awareness is both his greatest asset and his most dangerous defense mechanism. Galvin never smooths over Josh’s narcissism (his shock that Hugo makes the same minimum wage, his assumption that his research project matters more than his grandfather’s grief), yet his vulnerability remains achingly present.

Mary Beth Peil’s Beverly anchors the play as its moral and spiritual center. She delivers tough love without sentiment, grape juice at the seder without explanation (Josh never noticed she was sober too—”your head is fully up your own ass”), and the play’s most devastating line—”Now get the hell out of my life and go help somebody else, okay?”—with perfect calibration of affection and exasperation. This is a woman who survived being “a newly divorced wino in the 60’s” with “three jobs, acres of debt, no parents or grandparents around to come rescue her, two little kids who wake me up most mornings in a pool of my own vomit.” Peil makes us understand that Beverly’s refusal to enable Josh’s clinging isn’t rejection—it’s the deepest form of love. She knows recovery means leaving, not staying in your childhood bedroom working minimum wage and calling your grandmother when you crave a margarita.

Chip Zien’s Shrimpy provides the play’s emotional counterweight, a man whose crude jokes and preposterous bravado (“I look at the dicks. What can I say?”) are actually attempts to connect—with Josh as a gay man, with his own fading memory, with anyone who will listen. When he asks Josh about threesomes or shares embarrassing stories about getting caught masturbating, he’s not just being outrageous; he’s revealing what he still remembers even as he forgets his mother’s maiden name, and he’s trying to bridge the generational gap by meeting Josh where he is. When he can’t remember his Bar Mitzvah Torah portion but suddenly, effortlessly chants his original portion from 70 years earlier, Zien gives us both the comedy of the moment and its underlying ache: memory is a mystery, holding on to some things while releasing others without logic or mercy.

Brasch’s script note reads: “Play against the pain. In spite of everything, let this be a celebration of life.” Butler’s production honors this instruction. The senior aerobics class with its lion’s breath squats, Josh’s spinach rain from the heavens, Shrimpy’s quest for naked blintzes dipped in sour cream—these moments aren’t comic relief, they’re the point. Laughter and grief aren’t opposites in this play; they’re counterpoints in the same composition, each making the other possible.

The final scene earns its emotional weight through this accumulated specificity. When Josh returns after a year sober to find Beverly in cognitive decline—the woman who saved him now staring into space—the play calls back to an earlier moment when Beverly cleaned Josh’s snot-covered shirt with her handkerchief. Now Josh cleans Beverly’s face with a tissue, completing the circle of care. She briefly awakens (“Stop that! Fucking stop that!”) before retreating, but then she grabs his arm and they hold each other. The person sitting next to me was in tears. So was I. We’d earned this moment through two hours of theatrical invention grounded in human truth, comedy counterpointing sorrow, the slow accumulation of grace.

Brasch’s script includes a crucial note: “There are no proper transitions in the play. This will necessitate divorcing yourself from the literal and finding creativity workarounds in design and staging.” Director Shelley Butler and scenic designer Takeshi Kata take this challenge seriously, creating a space that feels like “the inside of Josh’s brain—scattered, irreverent, and slowly healing.” The Atlantic production doesn’t try to show us a realistic bookstore, then a realistic assisted living facility, then a realistic canyon—instead, it gives us a fluid theatrical vocabulary where the grandparents’ four chairs remain constant anchors while everything else shifts through association and memory.

The genius of Butler’s staging is making the grandparents function simultaneously as real people Josh visits and as manifestations of his consciousness. They sit in their chairs throughout, watching, reacting, occasionally stepping forward to enact a memory or embody one of Josh’s spiraling metaphors. When Josh describes his “train of thought,” they line up like rail cars; when he shifts the metaphor to a “river of thought,” they undulate in waves across the stage. This could feel precious or arch, but Butler and the ensemble commit so fully that it becomes emotionally legible: this is what it feels like inside a mind trying to make sense while broken, where past and present collapse into each other, where the people you love become both themselves and the stories you tell about them.

The convention allows Brasch to dramatize what’s typically undramatizable—the texture of early sobriety, where you can’t focus, can’t remember, can’t stop your thoughts from racing toward the “Wild Wild Turkey Ocean.” It also lets him show us how Josh’s grandparents are always with him, even when he’s alone, shaping his thinking, offering wisdom he doesn’t yet know how to hear. They’re not just his Greek chorus; they’re his conscience, his memory, his better angels.

This theatrical vocabulary proves essential in the play’s most wrenching moments. When Josh blacks out after drinking vanilla extract at the grocery store, the stage goes dark and we get “sounds from the following night punctuated with images, quick flashes, impressionistic windows into a mind under the influence.” When Irene appears in Josh’s dream dressed as a Nebraska farmer wanting to be buried in a cornfield, we understand we’re in that liminal space between memory and imagination where grief does its deepest work. The form doesn’t explain these moments—it trusts us to feel them.

Butler’s direction makes clear that Josh’s interior reflection on his life, his attempt to help his grandparents, and his eventual realization that he needs their help constitute the “reality” of the action. We’re not watching a straightforward narrative of a young man’s recovery; we’re inside that recovery as it happens, messy and associative and slowly, painfully coherent.

The play’s architecture rests on a fundamental reversal: Josh arrives in Denver convinced he’s there to save his grandparents from cognitive decline, but the deeper truth emerges slowly—they’re saving him from himself. His research project (spinach, aerobics, Hebrew lessons, museum trips) isn’t wrong exactly, but it’s beside the point. He’s trying to control the uncontrollable, to fix broken thinking with broken thinking, to avoid his own grief and shame by drowning himself in someone else’s crisis.

Beverly sees through this immediately. After Josh misses Irene’s funeral, she confronts him with surgical precision: “I don’t think you’ve given a single thought to how I feel. Not one. The whole world revolves around you. Your feelings. Your thoughts. Your problems.” But she also offers him the path forward—not through Josh’s elaborate cognitive theories but through the simple, humbling work of recovery: meetings, phone calls, asking for help, showing up. “If she can ask for help, if she can forgive herself, if she can go to meetings with her two toddlers in between shifts, you can surely muster the strength given your subsidized suburban lifestyle to extract your head full of shitty thoughts right out of your ass.”

The canyon scene crystallizes the play’s central wisdom. Josh asks if Cognitive Reserve is even worth pursuing given that “the higher the reserve, the sharper the fall.” Beverly’s response cuts through Josh’s anxious intellectualizing: “Of course it is. Look at this. We’re here. Right now. We know nothing and yet: We are here, honey.” Then she makes Josh yell into the canyon—”I KNOW NOTHING!”—and the grandparents echo it back. This is the opposite of Josh’s controlling research project. This is acceptance, humility, presence.

The play’s most devastating irony: Josh succeeds in helping his grandparents not through his Cognitive Reserve project but simply by being present, by playing Scrabble with his mom, by holding Shrimpy’s arm at his Bar Mitzvah, by sitting with Irene even when she can’t respond. And they help him not through any grand intervention but through their mere existence—Shrimpy’s vulnerability beneath the jokes, Irene’s grace in her dream visitation, Beverly’s refusal to let Josh make her his crutch. “Now get the hell out of my life and go help somebody else, okay?” This isn’t rejection. This is the final gift: permission to leave, to grow, to live.

When Josh returns after a year sober to find Beverly in decline, he’s learned the lesson. He doesn’t arrive with spinach or theories. He cleans her face, he holds her, he stays present with what is rather than what he wishes could be. The higher the reserve, the sharper the fall—but they had that year together, and it was worth it. The Cognitive Reserve was never about preventing loss. It was about building a life rich enough to withstand it.

Some critics at the Geffen Playhouse premiere felt “The Reservoir” was “a good play that could be a great one,” that it “skims the surface” and needed to “plumb the depths more.” I suspect they were looking for a different kind of play—one with more traditional dramatic architecture, where Josh’s transformation is spelled out in clearer beats, where the emotional payoffs are more conventionally earned. But Brasch has written something more ambitious and, ultimately, more truthful: a play that trusts its audience to feel the depths rather than having them explained.

The “scattered” quality that some critics read as lack of focus is actually the play’s formal precision. This IS what it feels like inside a mind broken by addiction and early sobriety—the racing thoughts, the inability to sustain attention, the constant collapse of past into present, the desperate search for patterns and answers that might make sense of chaos. The grandparents functioning as Greek chorus aren’t a gimmick; they’re how we actually carry our loved ones with us, as both real people and internalized voices shaping our consciousness. The play doesn’t skim surfaces—it operates on multiple levels simultaneously, trusting us to hold complexity.

What makes this Atlantic production succeed is that Butler and her ensemble understand Brasch’s script note: “Play against the pain. In spite of everything, let this be a celebration of life.” They don’t push for tears or inflate moments with false emotion. They let the comedy be genuinely funny and the grief be genuinely wrenching, trusting that audiences can hold both at once. Galvin, Peil, Zien, Aaron, Maloney, Heidi Armbruster, and Saldívar create a true ensemble where no one is merely serving the mechanics of Josh’s journey—they’re all living, breathing people with their own reserves and their own inevitable falls.

The play’s final image—Josh holding Beverly, who briefly awakens before retreating back into her decline—earns every ounce of its emotional weight through the two hours and fifteen minutes that precede it. We’ve watched Josh try to control everything, fail spectacularly, learn humility, leave, return changed. We’ve watched Beverly teach him the hardest lesson: that love sometimes means getting the hell out of someone’s life so they can grow. We’ve learned alongside Josh that you can’t fix broken thinking with broken thinking, that the higher the reserve the sharper the fall, and that it’s worth it anyway because we’re here, right now, and that’s enough.

“The Reservoir” is a theatrically inventive, intellectually rigorous, emotionally earned meditation on memory, recovery, and mortality. It’s about learning that you can’t save anyone—and discovering what becomes possible when you finally stop trying.
