"Please. I have to be a part of this." You beg. You notice Dean grinning at you.
"You know, your very brave." He said. "Yeah, she's a part of it." He hand you a rifle. "Know how to use it?"
You look at him skeptically and he shrugged. "You never know." He sits down with you and starts going over the basics of firearms. Sam looks uncomfortable, and you can tell he still thinks it's a bad idea, but Dean is obviously in charge. He picks up some chalk and starts drawing pentagons and stars on the ground.
"Hey, I've seen one of those!" You say, interrupting Dean. "It was part of a book! That's a devil's trap!"
"Yes it is." Sam said. "If we can lure the demon into it, it can't move out."
"So, we'll cover the symbol with a mat, you will stand over it, and when the demon comes, wait until it steps onto to the mat, then GET OUT OF THERE." Dean tells you the plan. You shrug.
"Okay. But I still want the gun." You point to it. Dean grins and hands it to you, continuing the lesson on firearms.
A few hours later you are sitting in the middle of the mat, and the brothers are nowhere in sight. They had pretended to leave to trick the demon into coming for you. You don't glance around, but try and stay still and calm, so that he won't know you are trying to trick him.
The lights start to flicker and you hold your breath. That's the sign then... the sign it's coming. Behind you you hear a floor board creak and you know it's there. You finger the gun in your lap. It's packed with salt bullets. You ache to turn and put one into it's head, but you don't, you know you have to wait for it to step onto the mat.
The wait is forever, and you become very scared, but you are determined. It MUST die. Then a hair on the back of your neck stands up and you feel the mat move slightly. So it's stepped on it. You wait another two seconds for good measure, then you roll forward, off the mat. Something grabs your foot, but you lash out with your leg and it drops it! And then, you're off!
When you turn the demon is watching you, spitting mad. "Let me go!"
"No." You say. You raise the gun and fire. The noise is freaking loud, and the gun jolts in your hand, but the bullet goes flying into the things stomach. You know it won't kill it, but it was fun anyways. At the noise the brother's burst into the room.
"Are you okay?" Sam says, rushing over, but then Dean is laughing.
"She shot it! Ha!" He gins at you. "Bet you must have liked THAT."
"Yeah, it was satisfying." You answer almost evilly, "But I still want it dead."
"Well the only way to kill a demon is with this knife." He took out the strange-looking knife and twirled it around.
"Let me out!" The demon hissed, looking warily at the knife.
"I don't think so." Dean replied and proceeded to cut apart the trapped monster.
A few days later you leave back for the University, but you know you'll never be satisfied with it again. Now that you've had a taste of the supernatural life, you know that it'll be difficult to revert back to the same boring classes. Maybe, if you DO decide to drop out, you yourself will go hunting. Oh sure, there's no pay, no thanks, and you might end up on the cops 'most wanted' list, but ridding thew world of those horrible monsters...
You and Dean really hit it off after the demon was dead. Nothing ever really happened because you, at least, are a civil person, and you're fairly sure that you'll never see him or Sam again, but if you DO get caught up in the Supernatural world, perhaps you might cross his path sometime in the future.
THE END! But then, that isn't the end is it? If you want, you drop out of University and go hunting, and if you really want, you can meet the Winchester's again. Or maybe you do decide to live low, but nevertheless your life will never be the same again now that you know what lies in the shadows...
