Your primary job at this godforsaken convenience store isn't restocking shelves or mopping up... spills. It's separating the humans from the things that wear their skin. Successfully identifying a doppelganger is a three-part process: aggressive interrogation, minute physical observation, and rigorous story verification. You have five questions per customer to determine if they're a person or a poorly made copy. Fail, and you might just become the next thing that goes bump in the night. Success means living to see the sunrise. The gun is under the counter for a reason—make sure you're pointing it at the right thing.
The Three Pillars of Detection
Every customer that walks through that sliding door is a potential threat. To survive, you must become a master of paranoid observation, treating every interaction like a high-stakes interview. Your defense is built on three core techniques that must be used in tandem. Relying on just one is a surefire way to get replaced. You must question their story, scrutinize their appearance, and listen for the logical flaws that give the creatures away. Think of it as a checklist: Question, Look, Listen. Any single failure on their part is grounds for suspicion. Two failures is a death sentence—theirs, not yours.
Master Your Five Questions
You only get five chances to poke holes in a customer's story. Wasting them on pleasantries is a luxury you don't have. Every question must be a calculated test designed to trip up an inhuman intelligence. Your goal is to force a logical error, an unnatural response, or a blatant contradiction.
Start with Obvious Physical Flaws
If something looks wrong, it probably is. Your first questions should always target the most glaring physical abnormality. Don't beat around the bush. If a customer has bizarre, malformed hands, your first question should be, 'What's with your club hands?' or 'What's with your thick mits?' If they're wearing a scarf indoors in a suspicious way, ask about it. These direct questions put them on the defensive. A human will have a plausible, if flustered, explanation. A doppelganger will often offer a response that is logically sound on the surface but feels rehearsed, strange, or doesn't quite fit the context.

Probe Their Profession and Story
Once you've addressed the visual, attack their narrative. Ask about their job, where they're coming from, or what they were just doing. This is where many doppelgangers crumble. Their programming can't always reconcile disparate concepts. The classic tell is a contradiction between their stated profession and their appearance. A customer might claim to be a flight attendant, a job that typically requires a clean and professional look. If they are simultaneously covered in dirt and grime, you've found your discrepancy. A human would have a story ('My car broke down and I had to change a tire'), but a doppelganger's response might be a non-sequitur like, 'I'm a flight attendant. Why would I be dirty?'—a defensive deflection that fails to explain the evidence.
Ask Unsettling, Literal Questions
Sometimes, the best way to unmask a monster is to ask it a question that no normal person would ever have to answer. Questions about their fundamental humanity can short-circuit their logic. Consider asking, 'Are you alive?' or 'Are your limbs all in place?' A human will be confused or offended. A doppelganger, however, might give you an unnervingly literal answer. One specimen, when questioned, responded with phrases like 'I wear clothes as human as I've ever heard it' and 'I own arms and legs'. These are not human answers. They are the responses of an entity attempting to confirm its disguise by listing its component parts. This is an immediate red flag and often justification enough to reach for the gun.
The Physical Examination: Look for the Flaws
Before you even open your mouth, your eyes should be doing the work. Doppelgangers are imperfect copies, and the manufacturing process often leaves behind telltale errors. These range from the subtle to the grotesquely obvious. Train yourself to perform a full-body scan the moment a customer enters.

Unnatural Anatomy and Bizarre Behaviors
Look for things that just aren't right. Proportions might be slightly off—limbs too long, a torso too wide. Their movements might be jerky or overly smooth, hitting the counter in a 'silly' way. Some tells are impossible to miss. One particularly advanced doppelganger, disguised as a local sheriff, was observed spitting a stream of rain forward from its mouth. This is a complete violation of physics and an undeniable sign of its non-human nature. Don't second-guess these moments; they are the clearest signs you will ever get.
The Telltale Seam
The most definitive physical proof of a doppelganger is the seam. These creatures are manufactured, and sometimes the process leaves a visible line where the synthetic skin is joined together, often running down their back. It's difficult to spot, as you usually only see customers from the front. But if you can catch a glimpse of their back as they turn, look for it. One subject, 'Tommy Delgado', appeared twice. The second version, when questioned about his aversion to shirts, claimed they had 'seams'. A quick look at his back revealed he had one too. This is irrefutable evidence. If you see a seam, the conversation is over.
Cross-Examining Their Story for Inconsistencies
A doppelganger's disguise is more than skin deep; it's also the story it tells. Just as their bodies have flaws, so do their narratives. Your job is to be the editor, finding the plot holes and contradictions that reveal the fiction.

The ID Doesn't Lie (Usually)
If you're presented with an ID, check it carefully. Does the photo look right? More importantly, does the information align with their story? Checking the birth year can give you a quick sense of their age. If 'Jade' from '93 looks fifty, you have a problem. While an ID can be faked, it's another data point. A flawless ID supporting a flawless story is a good sign. A strange ID combined with other oddities is another nail in their coffin.
The Repeat Customer Test
Pay attention to familiar faces. Doppelgangers can and will copy people you've already served. This creates a dangerous scenario: is this the real person returning, or is it a copy? The 'Tommy Delgado' case is the perfect example. The first one seemed human enough, with a plausible story for being shirtless. The second one was a paranoid wreck whose story about 'tracking fibers' in shirts led directly to the discovery of his own seam. If a customer returns, treat them with extreme prejudice. They are now a high-risk subject. Compare their story and demeanor to the first visit. Any deviation is a massive red flag.
Closing Take
Surviving the night shift is a game of inches and seconds. There is no room for the benefit of the doubt. Your default state must be suspicion. Trust your gut, but verify with evidence. Use your five questions like a surgeon's scalpel to dissect their stories. Scan every customer for the seams, the glitches, and the behavioral tics that betray their disguise. Remember the Nonhuman Eradication Taskforce (NET) exists for a reason, but you are the front line. Stay sharp, stay paranoid, and you might just live to clock out.
