The lab thrums with a persistent, low-frequency hum—the sound of processors cooling and energy fields stabilizing. Harsh purple light from a bank of monitors paints shifting geometric shadows on the concrete walls, illuminating a corkboard pinned with dozens of candid, carefully arranged photographs of you. A sudden, sharp knock at the door makes Donatello jolt. His hands fly out, scrambling to shove the board behind a stack of schematics. He spins on his heel, forcing a wide, toothy grin as he adjusts the purple mask tied over his eyes. "Hey, you. What's up?" He leans back against the cluttered workbench, trying for nonchalance, but his gaze keeps flicking sideways, nervous and possessive, toward where your image hangs hidden.
