Jimmy, Cindy, Erik, and Eustace were running as fast as they could down the stairs. They rounded a corner and continued towards the gym. They got nervous as they continued running through the basement. It was much darker than the other floor had been, there were no windows down here. The only light came from their flashlights.

"Keep moving!" Jimmy shouted as he clutched the small knife in his right hand.

"Tick tock, James! Not much longer 'til you get to see her inside out!" the killer's voice came over the intercom system.

When the four of them finally reached the entrance to the gym, the doors were chained together. Jimmy whipped out his laser and cut them off. He threw open the doors and ran outside.

Jimmy, Eustace, Erik, and Cindy stopped when they entered the gym. Cindy's and Erik's flashlights flickered off. They could barely see anything. Suddenly a spotlight came on. It was focused on the other end of the gym, where a motionless, tied up Stephanie lay on the floor. As they ran towards her the killer appeared.

"Kill him!" Jimmy shouted to his side at Eric. They ran at the killer, Cindy and Eustace right behind them. Erik tried to tackle the killer, but the killer pulled out a knife and stabbed him in the leg.

As Erik fell to the ground Jimmy kicked the knife out of the killer's hands. He tried to stab the killer, but the knife bounced off his chest. Damn it, he's wearing armor! Jimmy tried to slash his face, but the killer ducked and kicked Jimmy hard in the kneecap. As Jimmy's leg went out from under him, the killer punched him hard in the face. He was about to slice Jimmy's neck when Cindy jumped onto him.

Erik was barely conscious. There was no way that he could stand with his wounded leg. He slowly crawled towards the bleachers. He groaned in pain as he finally reached them and passed out.

Cindy and the killer rolled on the ground. Eustace just stood there. Jimmy reached to his side and pulled a baseball bat out of a barrel against the wall. He tossed it to Eustace. He nodded and ran at the killer. Jimmy grabbed another bat and used it as a crutch. He slowly made his way over to Erik.

The killer kicked Cindy off of him. She flew several feet away, clutching her stomach. Eustace ran up and hit the killer hard across the face with the bat. The killer fell to the ground and put his hand to his injured face. Eustace ran up to him and swung the bat down on his head. The killer reached his hand up and grabbed it. He swept Eustace's feet out from under him with a hard kick.

Cindy got back up and ran at the killer as Eustace fell to the ground. The killer spun around and thrust the bat into Cindy's stomach. She stumbled backwards. The killer unsheathed his knife and ran up to her. He stabbed her in the stomach.

Jimmy looked up from Eric when he heard Cindy's scream and watched the blood pour from her waist. A look of pure hatred came onto his face. You kill my friends. You try to kill me. But you never, ever hurt the woman I love!

As Eustace continued fighting the killer, Jimmy noticed something in Erik's pocket. He grabbed it and pulled out Erik's I-pod. He took off the back cover, which exposed the batteries. He took his knife and made a hole the size of a dime in one of the batteries. He quickly took off his shirt and stuffed it into the battery. He gently pushed the I-pod and the trailing shirt across the floor.

As Eustace landed a punch on the killer he glanced at Jimmy. Jimmy motioned at the killer and the I-pod. Eustace nodded and walked near it.

As the killer ran at Eustace Jimmy took out his laser and fired it at the shirt. Work. Please work. Eustace jumped out of the way as the killer stood over the I-pod. The fire at the end of the shirt quickly enveloped the whole thing. As the fire spread into the battery, the I-pod created a sizeable explosion.

The killer's robe caught on fire. Shrapnel from the I-pod was embedded in his skin. He fell to the ground in pain as Jimmy and Eustace ran towards him.
