Disclaimer: I actually got this idea from one of Katie Bell's stories, but I thought I would take my own spin on Sirius's thoughts. Don't hit me, please. Oh, and all characters belong to JK Rowling, etc.,etc.
I am Sirius Black. I am Sirius. I am Black. I am Sirius Black.
Thoughts grate against my mind, hoping to impound themselves upon my memory. They have little such luck. My body convulsively shudders upon the mat, self-will defunct. I am…
I am a man. Barely. I am a soul-sucked, innocent man. I am lost. I am losing. I am losing to the vile fiends.
Matted hair rests upon my shoulders. I finger it loosely, letting it fall, in clumps, through the gaps in my fingers. I remember this hair. This is my hair. Who am I?
My limbs lack muscle. I feel bones under the skin; fragile, dying bones. I know these limbs. Where have they taken me?
Who am I?
Fingers reach up to the worn face. Mouth, nose, eyes. Those eyes. How many times were those eyes crinkled with laughter? What gave them cause to?
I am…
I am sunken eyes, fragile bones, and matted hair. I am a mess. I am innocent. I am aching.
Oh, God. I'm aching. Aching for James. He knew the truth. He died for it. James, where are you? Where is Lily? Harry?
I pause.
Not Harry. He cannot touch Harry. I will not permit another death to befall the mistake of my hand. He is worth more than that. I am responsible for him.
I am responsible for another life.
I rise to my feet, legs shaking beneath me, and grasp the bars with my weak fingers. A dementor stands guard by the cell, its hood drawn over its ghastly face. I scowl at it, hatred overcoming all other emotions. You will let me out one day. I am responsible for one scared, abandoned child.
I am Sirius Black, and I will be free. I will break away from this desolate despair, and I will find my godson. I will destroy those that destroyed my life; that destroyed Harry's.
I release the bars, stagger back to the mat. Pain clutches my skull, I cry out in agony. I am…I am…
I am lost. I am losing this battle.
I am an innocent man.
