Tomáš and Zdenka’s trip to Paris

Tomáš and Zdenka’s trip to Paris is at once a professional opportunity, an intimate interlude, and a turning point in their relationship. Tomáš quietly arranges for Zdenka to attend an international polio conference, then preserves her belief that their joint selection was coincidence. In Paris, their five days together give Zdenka a glimpse of life and freedom beyond home; for Tomáš, the same closeness makes the future’s claims feel oppressive. The journey returns them not to a shared plan but to the first argument about whether their love can become a life.

The conference and its hidden arrangement

Zdenka receives the news at the hospital gymnasium, where she is excited to have been nominated for a Paris conference on polio and its treatment. The gathering brings international experts together, and selection is a significant honour. Tomáš tells her that he has come to speak about the conference, but she does not yet understand that his own involvement has shaped the opportunity.

His place on the delegation is nearly automatic: he is the hospital’s leading polio expert, and the Head of Paediatrics expects to attend with another doctor. The scientific programme includes Albert Sabin, an American of Polish origin, discussing trials of an oral live vaccine. Unlike the Salk vaccine, Sabin’s vaccine promises stronger immunity, but carries the danger of causing a real infection in some children. Tomáš is drawn to the balance the choice demands: the prospect of protecting many lives against the possibility that a few children may be harmed. The conference is therefore not merely a backdrop to the romance; it connects his professional work with his interest in judgments whose benefits and risks cannot be separated.

When the professor considers the programme’s physiotherapy sessions, Tomáš suggests Zdenka as an appropriate delegate because she is responsible for much of the remedial work with polio patients. His knowing smile makes the suggestion legible to the professor without requiring him to say anything more. The professor agrees and notes that Zdenka’s Party membership may help secure her exit permit. Tomáš never tells her he helped make the trip possible. He would rather leave intact her trust in a marvellous coincidence, which the narrative connects to his belief in contingency.

Paris as a brief shared life

For Zdenka, Paris is her first journey outside her country; for Tomáš, it is only his second visit to the West, after a military trip to Vienna when the city was still divided. Against the dull, monochrome impression of their home town and country, Paris seems bright and colourful. The hotel itself is a revelation to Zdenka: each room has a bathroom, and even free soap and toothpaste appear to her as emblems of capitalist luxury. Her wonder registers the distance between the material conditions she knows and the comforts the trip briefly makes ordinary.

They find it easy for Zdenka to move her belongings into Tomáš’s room, where an enormous double bed makes a new arrangement possible. For five days they share something close to married life: they make love in the same bed, fall asleep in one another’s arms, and wake to find the other still there, warm and creased with sleep. The intimacy is not abstract. It is built out of repeated nights and mornings, a shared room, and the unfamiliar permanence of waking beside the same person.

That domestic closeness brings incompatible feelings. Zdenka seems fragile against the scale of the bed, but Tomáš also feels nearly smothered by her presence. He longs to return with her to the Glass Tranquillity, where their lovemaking can resemble that of casual acquaintances, without what he experiences as the binding weight of obligation. The contrast shows why the trip cannot simply settle their relationship: physical intimacy deepens their bond, while the ordinary implications of shared life intensify his desire to evade commitment.

On the conference’s third day, the professor remarks that Zdenka seems a lovely young woman and hopes Tomáš will marry her. Tomáš agrees with the compliment, calling her a rusalka, but does not answer the question of marriage. Inwardly, he attends instead to the present: Zdenka in their shared bathroom, emerging from the shower, and coming into his arms. Marriage belongs to the future, and the future is precisely what he refuses to inhabit. His attention fixes on the immediate scene, not on what the five days might require of them afterward.

Return and the question of freedom

Back home, Zdenka almost weeps. Paris has shown her that doctors and physiotherapists are wanted there; she believes the two of them could have stayed, found work, and been together in freedom. Her response turns the journey from a pleasurable visit into a possibility she cannot easily dismiss. Tomáš answers by asking what has happened to her admiration of the Party. She clarifies that she is thinking not of the Party but of the two of them. Her proposed future is personal: staying together freely, outside the political loyalty he invokes to challenge her.

The episode’s reversal is sharp. The trip presented itself to Zdenka as an unexpected shared opportunity, but Tomáš had helped arrange her attendance; Paris then makes escape and life together seem imaginable, yet he cannot treat that possibility as a reason to choose a future. By the time they return, the five days have become past. Tomáš’s outlook admits only the present moment, figured as the Glass Room or Glass Tranquillity, with its cigarette and view over the city. The glass image offers a bounded refuge from obligation even as Zdenka asks what will happen to them now.

The question provokes their first argument. Tomáš does not wish to participate, but cannot avoid it. When he says there is no future, Zdenka names what a future would mean to her: motherhood and fatherhood, a place on the housing list, a home, and growing old together. These are concrete expectations, not a vague demand for permanence. She sees them as a possible shared life; she also recognizes that such a life seems unlikely with Tomáš as he is.

Zdenka proposes a break. She has been considering it since their return from Paris, perhaps even before the trip: they should be apart for a while, gain perspective, and wait to discover what each wants. The proposal makes the holiday’s closeness yield to separation. In the cool light of the Glass Room, the pair who had slept together in Paris begin to slip apart. Tomáš experiences the prospect as a loss, but is particularly unsettled by its ordinary terms: he had imagined losing his Ondine through a terrifying curse, not through a banal conversation about commitments and obligations.

Memory, contingency, and the unfinished ending

Afterward, they continue to encounter one another by phone, at the hospital, and eventually over a drink. Paris gradually recedes into the past and comes to seem like a fantasy with little footing in their ordinary lives. Even their recollections diverge. Tomáš remembers a visit to the Panthéon that Zdenka says never happened; she remembers a market on the Île de la Cité that he cannot recall, with a stall displaying tropical fish, caged birds, mice, and a sleek, self-sufficient rat. They laugh about the discrepancy, but Tomáš takes it as evidence for his belief that memory and imagination are alike.

The differing recollections give the trip an afterlife without restoring a shared version of it. Paris first appears to confirm possibility: the conference, the hotel, and the days in the same bed make another kind of life seem close. Once the journey is over, even the details that might anchor it are unstable. Zdenka’s hope for freedom and a family meets Tomáš’s refusal of futurity; their memories, too, cannot be made to coincide. The trip’s decisive consequence is not a settled departure or reconciliation, but the exposure of a divide between two understandings of time and commitment: she wants a future they can build, while he remains sheltered in the eternal present.
