A new but old ghost

She pushed herself up, her body protesting. Her head throbbed where she had hit it against the tree earlier, a dull counterpoint to the adrenaline still singing in her veins. She looked over at the woman, who was now struggling to her feet, brushing dirt off her torn blouse.

"Are you okay?" Rachel asked, her voice a little shaky.

The woman, who looked to be in her late forties with kind eyes framed by worry lines, stared at her, then at the **** man, then back at her. "You... you stopped him. He had a knife."

"I know," Rachel said, bending down to pick up the woman's purse. She handed it to her. "I think he hit his head pretty hard. We should call the police."

"Yes, of course," the woman said, taking her purse with trembling hands. She fumbled for her phone. "Thank you. Thank you so much. You're incredibly brave."

Rachel managed a weak smile. Brave. If only she knew. She watched as the woman dialed 911, her voice steady as she gave the dispatcher their location. A strange sense of satisfaction settled over Rachel. She had done it. She had used her power for good, for a real, tangible reason, and she had managed to get back into her body without any sign of Trevor. Maybe the fear had been for nothing. Maybe, now that Mark's body was occupied by a comatose mind, Trevor was truly trapped, a ghost with nowhere to go.

The woman finished her call and walked over to Rachel, placing a hand on her arm. "They're on their way. What's your name, dear?"

"Rachel," she replied.

"I'm Helen," the woman said. "You saved my life, Rachel. I don't know how you did it, but you did."

Rachel was about to say something, to deflect the praise, when she felt it. A shift in the air. A subtle change in the woman's posture. The warm, grateful look in Helen's eyes vanished, replaced by something cold, calculating, and utterly alien. A slow, predatory smile spread across Helen's face, a smile that didn't belong on the kind features of the woman who had just been mugged.

"You know," Helen said, her voice dropping to a low, conspiratorial whisper, "that was a very impressive trick. Possessing one body to protect another. A little reckless, but impressive nonetheless."

Rachel's blood ran cold. Her heart, which had just begun to slow, started hammering against her ribs again. "Who... who are you?"

The woman—Helen—tilted her head, her smile widening. "Oh, I've been called many things over the years. But you can call me Tom."

Before Rachel could process this, before she could even think to defend herself, the world dissolved. It wasn't the gentle lurch she was used to. It was a violent, brutal expulsion. An invisible ****, a tidal wave of pure will, slammed into her from within her own body. It felt like being physically thrown, her consciousness ripped from its moorings and flung into the cold night air. She cried out, but no sound came from her disembodied form.

She floated, dazed and disoriented, for a moment before her senses cleared. She was looking down at the scene. She saw her own body, standing there, looking perfectly fine. And she saw Helen's body, which was now slumped on the sidewalk, just as **** as the mugger. But that wasn't the worst of it.

Lying on the ground beside Helen's body was another ghostly form. It was translucent, shimmering in the dim light, but there was no mistaking who it was. The lanky frame, the sullen expression, the shock of messy blonde hair. It was Trevor. His ghostly form was stirring, his eyes fluttering open as he looked around, utterly confused.

"What... where am I?" he mumbled, his voice a hollow echo. "What happened?" His gaze fell on Rachel's body, which was now standing with a confident, almost arrogant posture. Then his eyes found Rachel, floating nearby. The confusion on his face vanished, replaced by a surge of pure, unadulterated rage.

"You!" he snarled, launching himself at her.

Rachel tried to back away, to float out of his reach, but she was still reeling from the violent ejection. Trevor's ghostly hands closed around her arms, his grip surprisingly strong for a non-corporeal being. He pulled her closer, his face twisted with fury.

"You did this!" he hissed. "You trapped me! You left me in that... that void!"

"I had to!" Rachel shot back, struggling against him. "You were hurting people!"

"I was having fun!" he screamed, his voice a chilling shriek in the night air. "And you ruined it! You took it all away!"

While they struggled, Rachel's body—controlled by the entity calling itself Tom—looked on with an amused expression. It chuckled, a deep, rumbling sound that was completely wrong coming from Rachel's mouth.

"Now, now, children," Tom said, using Rachel's voice. "Play nice."

Trevor ignored him, his focus entirely on Rachel. He shoved her, and she stumbled back, her ghostly form colliding with the solid trunk of the oak tree. She felt a jolt of pain, a phantom echo of the impact.

"Who is that?" Trevor demanded, gesturing wildly at Rachel's body. "Who's in you?"

"Oh, him?" Tom said, a smirk playing on Rachel's lips. He brought Rachel's hands up to her chest, cupping her own breasts through the thin fabric of her soccer practice shirt. He gave them a speculative squeeze. "Just an old friend. The name's Tom. And I'm the one who started all this."

Trevor's anger faltered, replaced by confusion. "Tom? What are you talking about?"

Rachel watched in horror as her own hands roamed over her body, touching her in ways no one but she ever had. It was a violation, a deep, intimate intrusion that made her skin crawl even in her ghostly state.

"So you're just a ghost?" Trevor asked, his fascination warring with his anger.

"Something like that," Tom replied. He slipped one of Rachel's hands down the front of her athletic shorts, his fingers disappearing beneath the waistband of her underwear. A soft moan escaped Rachel's lips, a sound that was both alien and horrifyingly familiar. "It gets lonely. But every now and then, a new player joins the game. Like you. Like her."

Trevor's eyes widened as he watched Tom's hand move beneath the fabric of Rachel's shorts.
