Prologue

"My head feels like it's going to split open. I lost an eye already. It's hard to see. I feel like crap.

Arms are starting to feel weird, too.

My right arm split into two.

Blood all over my body, can see my bones.

Need doctor bad."

The rest of the text was unreadable, too much of it covered by blood.

She sunk to her knees upon reading these words, the last part of her sister's diary. She knew all along that something bad had happened. Awhile back, they had found her sister's body, though they had thought she was dead. Now, the body was gone, and this book was in it's place. The writing inside all pointed to one horrifying conclusion, one that she didn't want to believe, though she knew it was true. She was not naive enough to believe otherwise. Her older twin had become one of those... things. If only Rachael had joined the BSAA with her instead of the FBC, maybe this wouldn't have happened.

"Rylee..." Jill said quietly, looking at her.

"Rylee, I'm sorry." Parker said over the radio.

"Yeah. Thanks." she said, continuing to stare down at the book she was holding as if it would make some kind of difference.

"Rylee." Parker said. Rylee brushed her blond hair aside for a moment and wiped a tear from her brown eyes. She always wore her hair in her face, just like her twin sister, Rachael, though, unlike Rachael, who parted her hair to the right, Rylee parted hers to the left, Rachel's hair was longer than Rylee's. Aside from that, they looked identical.

"Rylee, you need to get out of there, alright? It's not safe for you to stay here." Parker said. Rylee nodded.

"Yeah, you're right, Parker." she said. Just then, something jumped against the window from the other side. It was deformed, twisted, covered in blood, and it had another arm sticking out of its right arm. It looked like an ooze, though there was a faint semblance to its former self. They knew what it was, or who it had been before. It was Rachael, though she was mutated practically beyond recognition.

"Found you." it said. The voice sent a chill down Rylee's spine. It sounded so much like her sister, yet still not. The creature that used to be Rachael ran off down the hall.

"I can't believe that thing is... Rachael." Rylee said.

"No, Rylee. That's not your sister anymore." Parker said over the radio. He wished at that moment that he hadn't stayed behind at the cargo lift, that he could be there with her to comfort her in person.

"You're right, Parker. That's not her anymore." Rylee said. She closed the book, and she and Jill ran out into the hallway after the Rachael ooze.
