I could see. I was in the corner of the office but something was wrong. I could see myself. My hair was pure white, my eyes as well. The other me gave a spin and she was in front of me. She gave a little laugh and I saw the three professors turn around.

"Oh dear well that was fun." my replica said, grabbing my chin and looking at me. I pushed away and bumped into the wall.

"Who are you?" I asked.

"Oh well Cassy isn't it obvious?" The other me answered and I stiffened as she said the name Julia had given me.

"No."

"Oh well I never accused you of being very bright. I'm you Cassy. I'm your power." She answered and the three professors shared a look.

"Stop calling me that."

"Fine then I'll be Cassy, I always did like Julia. The… short… time we knew her." Every word sounded like bells. My voice didn't sound like that.

"Wonderful. Now go away. Leave me alone. I don't want you."

"You don't want power?"

"No."

"You're lying."

The other me slapped me across the face and I pushed her away. She gave a playful smile and touched her mark. I screamed, my wrist on fire. She took off her finger and I stopped screaming and looked at her.

"What the bloody hell was that?" I asked and she gave a little laugh.

"I'm the Power Cas. I control your power. You cant beat me." She answered and then looked from McGonagall to Snape to Dumbledore.

"Ooooh wonderful you brought me something to play with." She said and with a flick of her wrist McGonagall was sent flying into the shelves.

"Stop!" I yelled and put my finger on my mark. She twitched and looked at me, her eyes burning.

"You wanna play Cas? I'm more than happy to… whip you into shape… as some people say these days."

"Stop hurting them, what do you want?"

"I want control. You've been hiding me in that horrid head of yours. I must say you are no stranger to lies."

I ignored Snapes look and instead looked at Dumbledore who was supporting McGonagall. He was looking straight back at me.

"Then go back." I said, still looking at Dumbledore.

"S'cuse me?"

"I said go back. You're not wanted here."

She put her finger back on the mark and I screamed falling to the ground.

"You can't fight me." She laughed, stepping on my leg and breaking it with a sickening crunch.

"Says you." I spat out and kicked out, hooking my foot with hers and pulling hard. She fell crashing to the ground and I put up my walls, watching her disappear. I stayed on the ground, holding my leg and falling in and out of consciousness. I saw Snape walk over to me and pick me up with ease. Following Dumbledore and McGonagall, he carried me to the hospital wing where I fell unconscious.

I woke up and looked around groggily. Snape was sitting in the chair next to me, grading papers and Madam Pomfrey was pacing by her office.

"Go away you're gonna make the sick people depressed." I groaned and he turned his head.

"I'm glad you're awake." He said and I ran my fingers through my hair.

"How long was I out?" I asked and I could see the hesitation on his face.

"About a week."

I sat up, alarmed and then immediately wished that I hadn't. My head felt as if it was about to burst, and I lay down again.

"Wonderful." I muttered and he gave a nod, I almost thought that he was going to smile.

"Well the blasted red headed twins have been coming here everyday to check on you, its rather bothersome." He said and I gave a smile.

"And how long have you been here?" I asked, he stood up, essays in hand and looked at me.

"Whenever I don't have a class, although my potion stores are a mess." He answered then left.

I got up, ignoring my head, and attempted to stumble out of the hospital wing, collapsing next the bed and resting my head on the floor.

"Miss. Potter where do you think you're going?" Madam Pomfrey asked and I sighed.

"Nevermind." I answered and she gave a small smile.

"Do you need help up?"

"No, just leave me here I'm fine."

She shook her head and walked away, leaving me alone. I felt a single tear escaped my eye and I felt it trail down my face, hearing it slip onto the hard floor under me. I sat up with difficulty and tried to bring my knees up to my chest. One of my legs was completely useless, lying limp and unfeeling. I tried to heal it but more pain just shot up my leg and I cried out.

"What's wrong?" Madam Pomfrey exclaimed and she was out of her office in a second.

"You tell me I can't heal my leg." I said and she stopped. "What?"

"I don't know what's wrong with your leg and why you can't heal it but I can't seem to heal it either. You should be in St. Mungos right now but the Headmaster is saying no." She said this last part like it was a huge thorn in her side and she just wanted it out.

"Wait!" I yelled and she jumped, "Wheres McGonagall is she okay?"

"Yes Minerva's fine although she had a horrid hit to the head and she has quite the limp." She sighed then walked back to her office. For an hour I stayed on the floor, alone, and hurting more on the inside than out.

"Is the bed not comfortable?" I heard and looked up to see Dumbledore.

"No its fine." I answered and he sat down beside me.

"Well then why are you on the floor?" He asked.

"I dunno, I was trying to walk out of here." I looked at my leg again, "Great success that was."

Dumbledore sighed deeply, looking too at my leg.

"Professor McGonagall would like to thank you."

"Why? I'm the reason she was hurt."

If I had never taken my walls down then McGonagall would never have been hurt. It was my fault, no one elses.

"You're not you're, Power, I suppose we'll call her, would have killed her if you hadn't stopped her. You probably saved the lives of everyone in that room, including myself." He answered and I looked up. He couldn't be serious.

"She's apart of me. Its my fault. Anyway you could probably beat her."

"I'm flattered."

"Its because of your beard, not really you but you're welcome anyway."

He laughed and stroked his beard making me give a little smile too.

"What are you to doing?" I looked up to see Professor McGonagall standing in the doorway with a smile.

"Well we were discussing the quality of my beard." He stated and McGonagall looked at us both strangely.

"On the floor?"

"Well I found her on the floor."

She looked at me now and I felt my heart break. She wouldn't be hurt if it weren't for me. She wouldn't be limping. It was my fault.

"Well she should be in bed." McGonagall said and I got up with difficulty, dragging my limp leg behind me as I struggled back onto the bed. I sat on the side of the bed, rubbing my sore leg then propping up my pillows up. Little did I know that while watching me work, McGonagall's heart was breaking too.
