PLEASE READ THIS A/N: The phrase, 'Never judge a book by its cover' inspired this fic as today I've said it myself. I've always wanted to write a demon-turning-good fic but I never got round to it. I really hope to hear what you all think of it!

Never Judge a Book

Chapter One

The place is damp, cold and dark. We circle each other and I stare into his host's green eyes. I've been found out to be plotting to leave Hell perminently, and my demon-lover and I are now locked in battle state. Combat between two demons is only good for the one that isn't in the wrong and I'm terrified that more are going to show up, my loaned heart pounding sickeningly in my chest. I'm almost too scared to fight this battle but I stand my ground. It's all I can do.

"You've betrayed us." He hisses angrily, pointing at me with a blade equal to that of my comrade, Ruby's.

"I never wanted to be a demon, Verin!" I cry, trying not to show my fear and distress, "I never asked to be born into this!"

"None of us did, only those angels that fall wanted this!" Verin replies, grabbing my arm and pulling me close, "You and I, my little princess, are going to have everything we ever fought for!"

"No we aren't!" I sob, "Lucifer will slaughter us all when we get him his prize!"

Verin slaps my face so hard that I can feel my host's cheek burning, and tears burn my borrowed eyes as I feel real pain for the first time.

"You insolent bitch, after everything he's done for you!"

"He's done nothing for me! We've all worked for him and received nothing in return, don't you understand that?" I scream, jumping as Verin lunges with the knife.

I try to dodge him and I cope pretty well, managing to keep him away the best I can, until I end up on the ground on my back with Verin above me, that knife pressed to my throat. I whimper (actually whimper).

"Oh, Nina…you disappoint me, my girl. You've gone somewhat soft since you've been wandering Earth." He laughs, about to kill me but being stopped by none other than Ruby's knife being slashed across his throat.

I see Lucifer's vessel before me and then Michael's vessel, also the Angel of Thursday, Castiel. I can do nothing but roll my eyes to black out of instinct and I immediately switch them back, finding myself pressed down again with Ruby's blade against my throat, Michael's vessel right above me. Our eyes meet and I know what he's been through in Hell. He doesn't remember me. Thank the Lord he doesn't remember me, because if he did, it would just add to his already present guilt. I go as far as praying that I won't be killed, and I see softness in Michael's vessel's eyes. I hope that what I've just seen means he's going to spare me.
