Cassandra arrived first, as she always did. No one noticed. She sat at a corner table in the hospital cafeteria long after dinner service had ended, the fluorescent lights dimmed but never fully off, as if the building itself refused to rest. She had learned long ago that arrival time didn’t matter. Being early had never helped.

Ignaz Semmelweis came later, hands still damp, as if he’d stopped at every sink on the way. He looked around briefly, then sat across from her, placing his hands flat on the table—palms up, clean, empty.

They regarded one another with the tired familiarity of people who had never met but had always understood each other.

Cassandra had warned cities before they burned. She had spoken clearly, urgently, with devastating accuracy. No one doubted her sincerity; they simply dismissed her prophecies, the result of curse placed by Apollo after she refused his romantic advances.

Semmelweis, by contrast, had not warned of what might happen. He had shown what already was happening—women dying in childbirth, their deaths traced directly to unclean hands meant to heal them. He had brought numbers, comparisons, proof. And for that, he had been destroyed.

People often confused their burdens, lumping them together as examples of ignored truth. But Cassandra knew the difference. She had threatened the future. Semmelweis had threatened the present—and worse, the past. He had suggested that good men, educated men—doctors—had caused harm not through malice, but through the routine practice of carrying “cadaverous particles” from autopsies to maternity patients and causing childbed (puerperal) fever.

That was unforgivable.

Modern medicine, they observed together, liked to think it had evolved beyond such failures. It called itself evidence-based now. It wrapped decisions in guidelines and committees and dashboards glowing green with reassurance. It preferred data that comforted rather than accused. It loved averages because averages diluted responsibility to individuals.

Cassandra watched the cafeteria screens cycle through hospital announcements—quality scores, safety milestones, cheerful slogans about excellence. She wondered how many warnings lived quietly beneath those numbers, unheard because acknowledging them would require implicating those who established the measures and those who accepted them without question.

Semmelweis noticed how clean everything looked. Floors polished. Surfaces wiped. Staff moving with ritual precision. Cleanliness had become synonymous with virtue. He had learned, too late, that cleanliness could also become absolution—bestowed not by repentance, but by a (germ) theory that arrived decades after his death and quietly reassigned the blame to invisible microbes.

In his time, they had accused him of being abrasive, unstable, disruptive. Today, Cassandra noted, they were kinder. Now they reassigned you. They thanked you for your passion and invited you to advisory roles. They asked you to stop practicing medicine directly—for the good of the system.

The system always survived.

They spoke—sometimes aloud, sometimes not—about the language that softened harm. How injury became “acceptable variance.” How suffering that did not register as mortality disappeared into footnotes. How no one said a protocol was wrong; they said deviation was dangerous. Not the outcome. The deviation.

Semmelweis reflected on how the rejection he faced was rarely emotional. It had been procedural. Meetings were held. Notes were written. His findings were discussed and carefully set aside. The harm continued, not because it was unseen, but because the truth was inconvenient.

He turned to Cassandra then, as if offering proof that little had changed. He spoke of modern hospitals where alarms now replaced intuition, where protocols arrived already armed with authority. He described mandates that required physicians to flood frail hearts with fluid in the name of sepsis care, even when experience—and the patient’s own lungs—protested. He spoke of elderly patients stabilized for years on low-dose antipsychotics, only to be stripped of them by regulation, their agitation and suffering accepted as collateral damage in service of compliance.

 In each case, the harm was acknowledged, documented, and justified. No one denied the consequences. They were simply reframed as necessary, inevitable, or statistically irrelevant. The problem was no longer disbelief. It was its opposite: tenacious adherence to procedure, regardless of outcome

Cassandra recognized that evolution. In her world, disbelief had been blunt and cruel. In his, and in ours, it was refined. Polite. Slow. Far more effective.

They wondered whether anything had truly changed.

Alerts still fired. Protocols still marched forward. Patients arrived breathing and left diminished, their suffering categorized as expected. The system recorded success. Charts glowed green.

And yet—here and there—someone noticed.

Someone paused.

Someone remembered.

Those were the dangerous ones now.

As they stood to leave, Semmelweis washed his hands again. The motion was automatic, soothing. Cassandra watched him, amused and sad.

Clean hands were easy, she knew. They were measurable. Teachable. Auditable. Innocence was harder. It required humility, discomfort, and the willingness to admit that harm could occur without malice, reinforced by stubbornness.

They parted without ceremony, drifting back into myth and memory, leaving behind a hospital that would continue humming, counting, certifying itself safe.

Somewhere nearby, an alert sounded. No one looked up.

And the harm—quiet, documented, justified—continued to accumulate.
