The turtles were on their usual night patrol when they spotted a group of Foot Clan members stalking a woman in a dark alley. Wasting no time, they sprang into action, engaging the ninjas with their signature skill and coordination. The enemies, though numerous, were no match for the mutant turtles, who defeated them with ease. The woman, who had been the apparent victim, approached them once the last Foot Clan ninja was neutralized. Leonardo, ever the leader, stepped forward to make sure she was okay.

“Are you hurt?” he asked seriously, but with a tone of concern.

The woman, instead of appearing scared or grateful, gave them a smile that seemed a little forced, but convincing enough.

“No, I’m fine. Thank you for saving me,” she replied in a soft, calm voice. Her demeanor was oddly pleasant, almost as if she wasn't affected in the slightest by the presence of four huge mutant turtles.

"Wow, it's rare that someone doesn't freak out when they see us," Mikey commented, his curiosity piqued by the woman's reaction.

She just kept smiling, not a trace of fear in her eyes. She even approached Mikey, looking at him in a peculiar way.

"I guess I'm hard to scare," she said in a silky voice that made the four brothers exchange glances with each other.

Raphael frowned, sensing that something wasn't right, but he couldn't quite put his finger on what it was. Donatello, for his part, analyzed the situation with a bit of skepticism.

"Well, at least you're safe," Donnie added, trying to keep the conversation casual, although an uneasy feeling lingered in his mind.

However, what they didn't know was that they had just saved a psychopath, a woman who had committed several murders. Her calm, kind facade hid a disturbed mind, one who didn't see the turtles as heroes, but as mere tools for her own ends. As the turtles returned to patrol, satisfied with their good deed, she watched them with a gaze that exuded a disturbing mix of interest and malice, waiting for the right moment to make her next move.
