"Then I will leave you where you can be found," Ari decided. "People need you where the world is soft. Or fierce. Wherever."

It looked like a theater mask, smooth and white, but when Ari turned it in their hands faint lines traced themselves across the surface like veins. A single word had been carved into the inside of the jaw in tiny, careful letters: "isaidub."

Ari kept using the mask. It became a tool and a burden; a lonely person’s miracle and an instigator of necessary accidents. Sometimes Ari muttered questions—Are people worth the upheaval? Is truth that does not ask permission still a kindness?—and the mask answered, always in the same tone: Truth is the river. The rest is how you learn to swim.

Ari walked into the city the next morning wearing the mask under their hood like a secret. The subway compressed everyone into an anthology of faces; the mask hummed, impatient. At the office, the elevator stopped between floors and a woman with too many bracelets stood beside Ari, rehearsing a lie or a compliment—Ari couldn't tell which. The voice inside the mask suggested a single, clean sentence. Ari uttered it aloud.

One evening, when the sky above the river looked like a bruise and the bridge hummed with commuters’ tired feet, Ari found the mask heavier. Not as an object, but in the hollow inside the throat. The city had been changing; in small ways it was kinder, in other ways more precarious. The mask had moved people, but it had also moved institutions, systems that liked the predictability of polite lies.
