Cindy was rubbing the back of her aching head when a killer came up behind her. She turned around to see him holding a knife above her head. She was about to scream when Jimmy's words swam through her head. Expect the unexpected. All bets are off. She covers herself with a towel instead of running. Instead of running. Instead of running.

Cindy held in her scream and jumped to the side. The killer slammed his knife into the floor. He struggled for a second to pull it out of the ground, but that second was enough for Cindy to start running.

The killer chased after her as she ran down the hallway. Cindy ran faster than she had ever run before. She looked over her shoulder and saw that the distance between the killer and herself was growing. Her sides started to hurt. She was about to slow down due to the pain when she remembered something. Never assume you're safe. She ignored the pain and kept running.

"Cindy!" Jimmy shouted as he took the gun back out of his pocket and cocked it. He was running as fast as he could down the hallways. He wasn't sure where she was, or if she was conscious. He just prayed that he could reach her in time.

As one killer continued to chase her down the hallway, another masked murder waited at the other end. He hid in the shadows as Cindy made her way towards him. He saw Jimmy coming from another hallway, about to intercept the killer. Ok, the kid is coming. And he's got a gun. I can stick with the plan and risk getting killed, or I can do something else and watch the kids finish each other off. Yeah, I like the second idea better.

He pulled out a smoke grenade and a gun. He fired several shots into the other killer's head. He then threw the smoke grenade and ran towards the other killer's body.

The one remaining killer knew he had to act fast. The smoke would clear in about thirty seconds. He stopped by the body and ripped the cloak and mask off of the now dead Mr. Benjamin. He tossed the robe in Jimmy's direction and the mask in Cindy's. He threw his gun towards Cindy as well. He pulled out another gun and ran back into the shadows behind Cindy as the smoke cleared. This should be fun.

Jimmy coughed as the hallway became enveloped in smoke. He felt a light object cover him. He squinted and realized that it was the killer's robe.

Cindy also coughed as the smoke became thicker. She felt something slam into her thigh. She fell onto the ground and groped around the floor. She picked up the killer's mask and a gun. What the hell?

Eustace and Dave had taken a wrong turn and were in a completely different hallway.

When the smoke cleared Jimmy and Cindy were across from each other. Mr. Benjamin lay between them, dead and covered in blood. Both kids held a weapon and part of the killer's costume. They aimed their guns at each other as a reflex.

Jimmy spoke first. "Somebody killed Mr. Benjamin. He, he wasn't the killer. But...who is?" He noticed the gun in Cindy's hand and the mask at her feet. "Cindy?" he incredulously asked.

Cindy stared at Jimmy. "Jimmy, tell me it's not you. I'll believe you," she said as she kept her gun aimed at him. Her smile of hope turned into a frown when she remembered what Jimmy had said just a few moments ago. Expect the unexpected.

"I'm not the killer, Cind. Now I know you had a good reason to kill Mr. Benjamin. Why did you do it?" Jimmy cautiously asked.

"I didn't do it!" Cindy shouted.

"Why do you have the mask?"

"Why do you have the robe?" Cindy shot back.

They stood in the dark hallway, the only light coming from their fallen flashlights. They were across from each other, about ten feet apart. Both had their guns aimed at each other.

"Cind," Jimmy started to say. His eyes widened in terror as the killer slowly came up behind Cindy. "Look behind you!"

Cindy laughed. "I'm not falling for that old trick. Put down your gun," she instructed him.

The killer continued slowly walking towards Cindy. He reached into his robe. "Cindy! Trust me and look behind you!"

"Put the gun down!" Cindy said as the killer pulled out his knife.

"LOOK BEHIND YOU!"

"DROP THE GUN!"

Jimmy couldn't wait any longer. The killer was right behind Cindy. He aimed the gun over her shoulder and fired two shots. Cindy, thinking he was firing at her, let loose three rounds into his chest. Cindy looked behind her now that Jimmy was no longer a threat. Her face fell as she saw the killer running away.

"Jimmy!" she shouted as she ran towards the fallen boy. "Jimmy!" God, he was trying to save me and I killed him! I killed him!

Cindy ran up to Jimmy, who lay motionless on the ground. She could see holes in his shirt. Jimmy moaned softly. "Jimmy, I'm so sorry," she whispered as she cradled his head and began to cry.

"Cind," Jimmy whispered. "Cindy," he said a little louder. Cindy stopped crying and stared at him. Jimmy lifted up his shirt to reveal that he was wearing body armor. There was only a few drops of blood on him. "First rule of horror films...always aim for the head," he weakly joked.
