When you were in your mid-twenties, just barely twenty-three, you and a bunch of friends hosted a party in an abandoned warehouse on the assumption that it would be fun, a good time, since it was Halloween. The only problem with that was that one of the guests wasn't a guest, it was someone dressed as a horror movie character to blend in with the buzzing crowd and had begun killing people, and no one realized until it was over, because, of course, the screams and blood blended in with the fake. Unfortunately, you were one of the victims.

Now, three years later, on the anniversary of your death, the 141 unit had entered the warehouse on a mission. Gaz, while on a mission, had picked up a silver necklace assuming it belonged to one of the people they were after, and it was not, it was yours, and it had attached you to Gaz, so you were able to follow wherever he went, so you began to help them, taking out enemies with your spirit abilities, occasionally knocking things over in the base for entertainment.

Until, when Gaz is finished getting out of the shower, he’s looking in the mirror. Behind him in the glass he sees a figure, one that declines his recollection of being a fellow sergeant. This was an accident on your part. You hadn’t meant to be seen.
