The divide within the group gave Lucas an advantage. He capitalized on their disunity, maneuvering through their ranks with cunning and precision. As the chaos ensued, Rebecca turned her focus towards Casper, sensing his presence nearby. She believed that he would offer support and guidance in this critical moment. 

"I can help, come with me!" Casper led the way and took her away from her teammates. As she opened the door in front of her, she found herself in a garden of twisted and gnarled trees, their branches reaching out like skeletal fingers. The moon cast an eerie glow upon the desolate landscape, casting long shadows across the uneven ground.

Confusion washed over Rebecca as she realized that Casper had led her away from the battle. "What's going on, Casper?" she demanded, her voice laced with a mix of anger and desperation, "Where's Lucas?"

With a surge of dark energy, Lucas struck her from behind, knocking her weapon from her grasp. She stumbled backward, her resolve momentarily shaken.

With swift, purposeful steps, Rebecca closed the distance between her and Lucas. She moved with a calculated grace, her knife held firmly in her hand. As she neared, her focus sharpened, blocking out the surrounding turmoil.

Just as Rebecca prepared to strike, a sudden interruption shattered the moment. Casper, her trusted spirit companion and the one she had believed in, unexpectedly leaped to Lucas's defense. In a surprising turn of events, Casper turned against Rebecca, driven by his own hidden motives.

Casper materialized with a burst of spectral energy, positioning himself between Rebecca and Lucas. His once-friendly demeanor twisted into a malevolent sneer as he prepared to face off against his former ally. 

As Rebecca lay on the ground, her body throbbing with pain, a wave of anguish and disbelief washed over her. The weight of Casper's betrayal settled upon her like a suffocating fog, clouding her thoughts.

Maybe Casper intended to help her and mistakenly hit her instead of Lucas. Right? 

Casper turned to face her, his once-familiar features now distorted by a sinister aura. "I'm sorry, Rebecca," he said, his voice dripping with false sympathy. "But you've been blinded by your own naivety. Lucas offered me a chance at power, at freedom. I couldn't resist."

"What do you mean? What the hell are you saying?" Feelings of anger and sorrow intertwined within her, leaving her trembling with a mixture of emotions. She had believed in Casper, and trusted him with her life, only to be deceived in the most painful way imaginable. The realization that someone she held dear had chosen darkness over loyalty tore at her very core.

Or maybe he was just playing around, right?

But as Casper's malevolent intentions became clear, Rebecca could no longer cling to hope or denial. The evidence of his betrayal was etched in his twisted expression, in the way he aligned himself with Lucas, his once-trusted companion now turned enemy.

Her mind raced, desperately trying to make sense of the situation. How could Casper, who had fought alongside her, and shared moments of camaraderie and trust, now stand against her? The weight of the truth settled upon her, a crushing realization that shattered her faith and left her feeling vulnerable and exposed.

Rebecca and Casper clashed their confrontation a display of supernatural power. Their movements were swift and precise, each strike carrying the weight of their fractured bond. Rebecca's knife clashed against Casper's ethereal form, while Casper retaliated with bursts of spectral energy, aiming to weaken and overpower her.

As the fight intensified, Rebecca reluctantly tapped into her reserves of strength and resilience. Yet, her body trembled, not only from the physical pain but from the emotional turmoil that gripped her. Her eyes once filled with determination, now glistened with tears of betrayal. The ground beneath her seemed to spin, the once-familiar surroundings of the garden now twisted and distorted in her perception. She just had to focus on defending herself, cause there was no way she was strong enough to hit Casper. 

However, he fought with an intensity that surprised Rebecca, his spectral powers growing stronger with every passing moment. The battle between them became a desperate struggle, with Rebecca pushing herself to her limits.

But as the clash reached its peak, Lucas, seizing the opportunity, used the distraction to make his escape. With a sinister grin, he disappeared into the shadows, leaving Rebecca and Casper locked in their bitter confrontation. 

Rebecca knew that she couldn't afford to dwell on Lucas's escape. She redirected her focus towards Casper, her determination reigniting. She fought fiercely, anger surfacing beneath her sorrow, attempting to break through Casper's defenses and find a way to reclaim her spirit companion from the clutches of darkness.

Their battle raged on, the air crackling with energy as they exchanged blows and counterattacks. Rebecca's determination was unwavering, even as Casper seemed to gain the upper hand. She refused to let him control the outcome of this fight, refusing to let darkness prevail.

But in the midst of their intense struggle, the fight took an unexpected turn. A surge of energy rippled through Casper, and his expression shifted. For a brief moment, doubt and regret flickered across his face. In that momentary lapse, Rebecca saw a glimmer of her old companion, trapped and conflicted. 

"You have to hit him, Rebecca! Do it!" She heard Austin's voice from a distance, but she kept staring at him, all of Austin's words hung in the air.

Before she could react, Casper made a split-second decision. With a burst of spectral energy, he disengaged from the fight and vanished into the shadows. Rebecca was left standing, her heart heavy with conflicting emotions, as she dropped her knife.
