Deep within the Krang base, the four brothers crept forward, their footsteps barely audible as they kept their weapons ready. Suddenly, a desperate cry echoed through the metal hallways, calling for help.

“Listen! Someone’s in trouble,” Leonardo said, raising a hand to signal silence. Following the sound, they came to a dark cell where they found a teenage girl, tears streaming down her face, begging to be released.

“Please save me!” she screamed between sobs. Without hesitation, the brothers disabled the security systems and took her out of the cell. But in an unexpected twist, as soon as the four brothers approached her, the teenager betrayed them. With one swift movement, she pushed them into a nearby cell, activating the controls that caused the walls to begin closing in, threatening to crush the turtles.

From the other side of the bars, the young girl looked at them with inhuman coldness, her tears completely gone. "Pretending is easy when you feel nothing," she muttered indifferently, pressing the button that started the deadly trap. Without looking back, she left the place while the brothers struggled to find a way out.

Moments later, the teenager was running through the dark streets of New York, but there was no escape. In a dead end, the four brothers cornered her. Raphael pulled out his sais, full of rage, while Leonardo unsheathed his ninjatōs with determination.

"You thought you could betray us and come out unscathed, didn't you?" Raphael growled, advancing towards her.

Donatello held his bō firmly. "We don't know who you are or why you did this, but you won't betray us again."

Michelangelo, with a serious look uncharacteristic of him, swung his nunchakus. "This won't end well for you, girl."

The tension was palpable as the brothers prepared to face her, knowing that this time there would be no mercy.
