[ WP ] In a world of shapeshifters , how do we know who is who ?

`` Well atleast your not a shapeshifter, eh?'' I joked, raising a glass of liquid to my mouth. 
 All the flashing lights, the drunken laughter, and not to mention the sports blasting on the television and the music blaring in the next room over, it was hard to think clearly. 
 
 `` Haha, so funny. Want me to top off your drink?'' the bartender asked. 
 
 I gave him a quick nod and he snatched my drink off the table. My eyes scanned the room looking for anyone different. A girl roughly my size sat down directly beside me. 
 `` There's other seats open you know.'' I told her. 
 She shrugged it off and the bartender came back with my drink. He asked her what she wanted, and she ordered a drink I did n't recognize. 
 
 `` So whats your name?'' she squeaked in a unexpected high pitched voice. 
 `` Reia, you?'' 
 `` Mines Karma.'' she squeaked back. 
 
 The bartender came back with her drink. It was a florescent pink, with a little black straw and a mini umbrella poking out of the top. She leaned down to take a sip and thats when I saw it. A blue hologram on the back of her neck with the signature shapeshifter's trademark. 
 
 `` Hey Karma, did you hear on the news?'' I asked, watching her closely. 
 `` What?'' Karma asked, cocking her head to the side to look at me. 
 `` Shapeshifters were outlawed years ago.'' 
 
 I saw her expression momentarily change before I tackled her to the ground. We wrestled, and I could only watch in horror as her entire body shifted into a exact copy of my own body. 
 
 I put my foot to the wall of the bar itself, knocking over a couple barstools. She grabbed me by the neck, now being just as strong as me, and flung my head backwards onto the bar's wall. My foot slipped to the side, and I kicked her as hard as I could in the stomach. 
 
 `` Its ok, I got the fucking shapeshifter.'' she growled in a exact copy of my voice. 
 
 My vision was darkening. I tried to cry out, to tell them I was made of flesh and blood and she was the fake, but nothing came out. She smirked at me, daring me to get up and fight her. I only managed to raise my wrists before my head injuries overcame my will to stay conscious.
