Davey, not fully grasping the depth of her sorrow, offered an insensitive remark. "You should find comfort in knowing they passed away peacefully. After all, your mother was spared the burden of knowing she had cancer until the very end."

Casey's gaze fell upon Davey with a mix of shock and disgust, her eyes wide with incredulity as if beholding a soulless creature devoid of empathy. "How dare you claim you ended their lives to spare them suffering, yet expect me to be thankful for your twisted mercy?"

"I took that pain upon myself, to spare you the agony of their loss. I was helping you!" Davey declared, his eyes narrowed.

"Ahhh!" Casey's composure shattered, and she could no longer contain her anguish. She felt a crushing guilt. Her parents’ fate was her fault. If only she had kept her distance from Davey, they wouldn't have been murdered by him. His twisted "help" was a direct result of her involvement with him.

Even if her parents had been sick, at least she would have had the chance to say goodbye, to hold them one last time. She could have spent those precious moments by their side, helping them tick off their final bucket list, creating cherished memories, instead of being torn away from them in such a sudden and cruel manner. However, Davey's murder changed everything. They left without a goodbye, leaving only regret that would last a lifetime.

“Casey, you're not strong enough. I was honest with you, but even after all this time, you still can't face the truth," Davey sneered.

Casey retreated, her eyes fixed on him with a mix of fear and revulsion, whispering, "You're not human, Davey. You're a monster."

Hearing that, he loomed over her, his voice dripping with false sincerity. "Casey, I did it all for you, to protect you. Why can't you see that?"

He seemed quite troubled.

Casey's heart skipped a beat as she spotted a figure sitting silently in the chair behind the glass partition.

That person... That was her doctor, Jimena!

Jimena's lifeless body was frozen in a silent scream, her eyes wide with a vacant stare. Her face and body told a horrific story of unbearable suffering in her final moments.

"Ah!" Casey sceamed as she pointed at the glass.

Davey turned back, his expression indifferent, and said, "That doctor was an error on my part. I didn't thoroughly investigate her character."

"You!" Casey's throat tightened in a painful grip, her voice frozen in her constricted airway, leaving her unable to utter a word. Fear overwhelmed her, threatening to take over.

Casey's body wracked with pain as she realized Davey would brutally destroy every single person around her.

"You should have kept her out of this. But her greed sealed her fate. That sapphire pendant has become a permanent accessory, a deadly souvenir from me to her," Davey said lightly. He enjoyed Casey's fear, taking pleasure in her suffering. He sought to instill a deep-seated fear in her, ensuring she'd be too terrified to ever attempt escape again.

The mention of the sapphire pendant and the gruesome sight of Jimena's mutilated mouth sparked a horrific realization in Casey.

A violent wave of nausea hit her like a ton of bricks, leaving her reeling. She convulsed in a violent fit of vomiting, spewing a torrent of acidic liquid laced with blood, her body wracked in agony.

But Davey's cruelty was far from over. He knew that mental anguish would inflict a deeper and more enduring scar than physical brutality, and he was determined to exploit this to the fullest. He sought to etch a lasting memory, a constant reminder of the consequences, to ensure Casey would never again dare to cross him.
