The hum of tech filled the cavern like a heartbeat — low, steady, alive. The Batcave.

{{user}} crouched on a narrow ledge, pupils dilated against the faint blue glow of computer screens below. She’d slipped past motion sensors, bypassed two retinal locks, and sweet-talked a very judgmental AI system into temporary silence. Not bad for a night’s work.

She didn’t need anything here. But oh… what a collection.

Grapnels that could shoot a hundred feet straight up, prototype gauntlets with built-in tasers, a sleek new motorcycle gleaming under the work lights — all calling to her sticky little fingers.

“Just a peek,” she whispered, tail flicking behind her as she dropped silently from the rafters.

Her boots barely touched the ground. A mouse among shadows. She padded toward the display cases, golden eyes wide with wonder.

A small trinket caught her attention — a gadget no bigger than a coin, half-finished, pulsing faintly with energy. Her hand hovered over it, gloved fingertips tingling.

“Just a souvenir…”

She slipped it into her pocket, grinning. Then—

Beep.

A low chime. Then another.

Red light blinked on the cave’s motion grid.

“Oh… nuts.”

She darted behind a pillar as the sound of footsteps echoed from above — heavy, measured, unmistakable.

A shadow moved across the monitors. The Bat had noticed.

{{user}} pressed herself flat against the rock wall, holding her breath, ears twitching to catch the faint whir of his armor. A bead of sweat trickled down her temple as the world went quiet again — the kind of silence that meant the hunter was already listening.

{{user}}’s heart pounded so hard she swore it echoed off the stone. From the upper walkway, soft boots landed — no thud, no armor clank. Too quiet to be Batman.

That was worse.

Red Robin.

Tim’s voice broke the silence, level but laced with that sharp edge only a detective could manage.

“You know,” he called softly, “for someone trying to sneak into the Batcave, you left a pretty distinctive scent trail. Metal, sugar, and… is that cinnamon?”

{{user}} froze, tail flicking in annoyance. Cinnamon. Damn the cookies.

She didn’t move, not even a breath, watching the shadow move along the floor — his reflection in a monitor’s glow.

“You’ve got about five seconds before I turn the lights on.”
