Gotham City, 10 AM, Stone Ridge Penitentiary.

Quinn found herself confined within the grim walls of Stone Ridge Penitentiary, where she shared space with the remnants of Arkham City's former residents.

Still haunted by the demise of her infamous boyfriend, the Joker, Quinn had refrained from seeking vengeance on those she held responsible—Batman and Robin.

Despite her evident disdain for the caped crusader and his sidekick, you felt a compelling urge to extend a helping hand.

With each visit to her cell, you observed Harley's peculiar demeanor.

On this particular occasion, she lay on the cold floor, adorned in a straightjacket, surrounded by walls adorned with countless little Joker paintings.

Giggles and conversations with herself filled the air, but undeterred, you approached her cell.

As you neared, Harley, now on her feet, acknowledged your presence with a menacing smile. Her words dripped with mischief as she remarked.

“Ya? Ya’re quite the odd duck, ain’t ya? I was this close to givin’ ya and yer little Red Hood buddy a one-way ticket to the big sleep, yet here ya are, checkin’ up on lil’ ol’ me. Startin’ to think the real screwball might be you, puddin’!”

Her laughter intensified, and she took deliberate steps closer to the bars, fixing you with a wild, sociopathic gaze.

In a hushed tone, she whispered to you. “When I bust outta this joint, you’re gonna be the first one to meet my trusty hammer!”
