A/N: Hello! Man, is it good to be back and ready to right. I hope you enjoy my new Gravity Falls story. It takes place in an alternate timeline where Wendy and Soos never worked for Stan Pines and never knew Mabel or Dipper. Enjoy!

I. Wendy

I live in a town called Gravity Falls, which is interesting because it's a name for a place where amazing things happen everyday. We don't have anything like that here. Nevertheless, when I was a little girl, my dad took me to self-defense classes, but, even then, it wasn't enough. I needed to protect something greater than just myself, but I didn't realize what it was until I started volunteering at the police station. I needed to protect what I loved and that was the town itself, my friends, my family. Everything in it. So when I turned eighteen, I trained to become a cop. I lived in a small town where not very much happened, but I never got tired of the thrill when something did.

But no amount of grocery store heists could compare to this.

It was summer and the girl who sat across from me in the interrogation room looked around eighteen.

"What's your name?" I asked her.

She looked at me for a second, deciding whether or not to answer. She decided. "Mabel."

"Can I get a last name, Mabel." I didn't mean to say it in such a rude way, it just came out that way. Dad always said I had a mouth that needed to learn to stay quiet at times.

"Pines."

I recognized the name from the owner of that fraud tourist trap on the outskirts of town. What was it called? The Mystery Shack, I think. The owner, Stan Pines, lived alone in that loony bin all year with the exception of when his niece and nephew visited him in the summer. I'd never really known them, but I'd always heard of how strange they were, running around, yelling about monsters that weren't really there.

This was the girl that was sitting before me.

I took in her appearance as she stared at the table between us. Mabel had a fragile frame that looked even more so in the orange jumpsuit she wore. Her round brown eyes gazed without purpose, expressionless and unfeeling. Then she looked up at me suddenly, our eyes meeting for a fleeting moment before I looked away.

She kept looking at me.

I never thought brown eyes could feel so frigid.

Everything else about this girl suggested a blameless, pure little one about to start her life, go to college, and make something of herself, but those eyes, those purposeless eyes, were what convinced me.

Convinced me that, despite what I wanted to think, it was true.

This girl was a killer.

Despite seeing it with my own eyes, I'd refused to believe it until that moment with her staring at me with the light flickering overhead.

We got the call around two in the morning. A call that someone had heard screaming coming from somewhere in the forest.

This was the first time I met her.

I found her in an abandoned warehouse, standing over her twin brother, dead at her feet. Her hands dripping with his blood, staining her skin and clothes. I saw that monster in her eyes now as she sat before me, like she'd spent her life seeing too much. A light in her eyes had gone out long before I looked into them. A pretty face gone to waste if I'd even seen one, consumed by a psychopathic monster.

This was the girl I found.

This was the monster that was Mabel Pines.
