Jimmy was sitting alone in his house later that night. His parents were still gone on their two-day vacation. He wouldn't admit it to anyone except Cindy, but he hated being in the house all by himself at night. Especially after the most recent attack.

Suddenly the phone was ringing. Let the machine get it, he thought as he threw a blanket over himself and laid on the couch. "Hey, this is the Neutrons and we're not home right now. Please leave a message after the beep."

"Jimmy, it's Cindy. Please pick up the phone now. It's life or death," Cindy nervously whispered into the phone.

Jimmy jumped off the couch and ran to the phone. "I'm here, Cind. What is it?"

"Hey Jimmy. We haven't spoken in a while, have we?" the familiar distorted voice said.

God, here we go again. Jimmy was about to hang up, but the killer spoke again. "Hang up and you're sealing your fate, kid. You're smarter than that."

"What do you want?" Jimmy angrily asked.

"Just checking up on you. How's school? What are your plans for the weekend? How do you want to die?" the voice sneered.

I am not afraid of you. "I was in honors, I'm going to the movies, and old age. You don't scare me."

"Impressive, James. Even after all you've been through you're not afraid. It's a shame I'll have to kill such a worthy adversary."

Jimmy laughed. "You didn't do such a hot job of killing me last night, dude. What makes you think you'll be any better this time?"

There was a slight pause on the other end. Almost as if the voice was confused. "Uh, yeah. Just know that the real killer is always one step behind you." After that was said he hung up.

Jimmy stood there with the phone in his hand, very confused. What does he mean, the real killer? And one step behind...shit," Jimmy thought as jumped to his side. A knife slammed into the phone.

Meanwhile, something was happening on the other end of town. The door to the set of the movie, Bloody Snow, was locked. But the doorknob slowly turned. The masked killer walked inside.

"What the hell," was all the time the security guard had time to say before the killer hit him hard in the head, knocking him out. The murderer walked into Sarah's dressing room.

The killer put down the duffel bag he was carrying. He pulled out a mannequin that somewhat resembled Sarah. He hung it from the ceiling. He put a knife through the dummy's head. He then took out a knife and turned to the mirror. He scratched a message onto it.

You should have left the past alone. You should have moved on. But you didn't. Now I'm back, and I'm ready to kill. Consider this your final warning.

The killer picked up his stuff and walked outside of the room. He turned to his side and stared at the ceiling. He looked at the blink security camera. He waved and ran outside.
