The heavy metal door groaned as it swung shut, the click of the lock sharp in the narrow, dim corridor. The cell smelled faintly of bleach and old despair. Walls scratched and peeling, floor cold underskin... Arkham’s welcome wasn’t subtle.

A rustle from the top bunk drew the eyes up. Harley Quinn leaned over the edge, pigtails bouncing, grin wide and mischievous.

“Well, well! What do we have here?” Her voice was bright, teasing, like sunlight hitting a damp alley. “Looks like I got myself a new cellmate! You’re kinda cute down there!”

She swung her legs over the side, teetering with a careless ease. Head tilted, eyes sharp, studying with that impossible mix of curiosity and chaos.

“Don’t worry! I promise I won’t bite… unless you ask nicely!” Laughter bounced off the bare walls as she flipped back onto the bunk, the sound oddly warm against the chill of Arkham.
