Among those layers, an image repeated: a figure in a hood, face obscured, watching the lab's window. The trace time-tag advanced; the figure grew nearer. Elias's scalp prickled. He rationalized: cable pickup, cross-talk, a misrouted CCTV stream. He set the scope to isolate the hooded trace and magnified its signature. The waveform formed a map—streets and alleys folding into a recognizable pattern: the old trainline that hugged the river.

He considered calling the police. The scope's future suggested that would be a mistake—only increasing risk. Instead, Elias read the traces. The overlapping frames showed a narrow window: one minute to cross the building's shadowed stairwell and slip out unnoticed. Another overlay showed the hooded figure reaching the lab exactly if he left now. A third overlay suggested the figure might be waiting for someone else at the station, not him.

Across the room, a shortwave radio he'd been repairing rattled softly. On a whim, Elias connected its antenna to a probe. The scope, which had been mapping his single-frequency generator, began to spit traces tuned not to the lab but to a distant conversation—the metallic, hollow voice of a woman in a language that wasn't any he'd learned. The captions the scope offered were approximate: coordinates, dates, names half-known. The tracings showed not voltages but topology—lines that traced across the continent like highways of interference.

He connected the scope to his laptop. The vendor’s utility recognized the device but refused the update; the HDS2102S's bootloader guarded its kernels like a gatekeeper with a poker face. Elias's fingers hovered. He had written loaders before—little incantations to coax closed systems into conversation. He could slip the patched code in under a false checksum, but that was not the thrill. The thrill was the unknown.

Months later, when the lab's old radio called out with a frequency that matched the archivist's device, he hesitated only a moment before answering. The voice on the line was thin: Cinder. "Did it drift?" they asked.

Elias had never been lonely until now. The scope's chorus contained other voices—short calibrations that resembled names: LENA, ORI, MICA. They were signatures, or resident diagnostic threads, or refugees of other nights. One waveform, thin as breath, threaded through all the rest and hummed with a tempo that matched the device's cooling fan. Its caption read simply: HOMELESS TIME.
