Jace POV

I quickly pulled my blade out of Carly as she slid down the wall. I threw my blade down the alley, crouching by her side. She had one hand over her wound and the other helping her to sit. Carly looked awful and it was all my fault. I think I am completely losing my mind.

"Carly, I am so sorry. I haven't been sane lately and I took it out on you. I hope you can forgive me." I said as she spit some blood onto the pavement.

"Why did you keep calling me Jonathan?" Asked Carly

"My nightmares have also included me seeing Jonathan. Half the time I barely know if I'm awake or asleep. I thought it was real for the most part until now. When I saw Jonathan transform into you, I realized my mistake. I am so sorry." I said

"You need to tell Clary. You might be scared, but at least she can help you." Said, Carly, trying to get to her feet, but failing. I noticed she wasn't healing and that meant only one thing.

I pulled my sleeve up on my jacket and offered my wrist to her. She looked at it for a long while, before pushing my arm away. She painfully got to her feet and tried to leave the alley. She got about one step before collapsing back into my arms. There was no way she was getting out of this alley like this.

"Carly, you need to feed. The only way you'll make it is if you do. I am here and offering. Since I did this to you, it only seems right. Please, let me help you." I said extending my wrist out to her once more.

"I can't. I don't want to hurt you." Said, Carly, never taking her eyes off my wrist.

"I've been to hell and back, a vampire bite is nothing." I said

She looked up into my eyes and then back at my outreached arm. She grasped a hold of it for several moments before sinking her fangs deep into my skin. There was a twinge of pain then euphoric bliss. I had been bitten by Simon before and the feeling never got old. It felt like sex without actually having any.

Carly continued to drink for several more moments, hesitating before pulling away. Drinking blood brings a rush of energy and vitality to a vampire. Experienced vampires can control themselves to allow their prey to live, new ones always have hesitation. Carly pulling away was hard for her, I could see it in her reddish eyes.

I snapped out of my haze and pulled my sleeve back over my arm. I would heal the wound when I got back to the Institute, but right now I had to help Carly. She wiped her mouth and I helped her stand up. I made sure she was stable and then I began to talk, "We can't let anyone know about this. I want to tell Clary on my own terms and Simon would get upset."

"I understand. I will let you tell Clary and I won't make a peep to Simon. He already has enough on his plate and adding this will only make things worse. How we are going to explain the knife hole in my dress?" Asked, Carly, as I noticed the torn hole in the side of her dress.

"We'll say I came out to check on you. You were mad and when I tried to talk to you, you tripped. You tore the dress on a rock and the wound healed. It wouldn't be too hard to see that happening. They should believe that." I said as Carly nodded in agreement.

"Jace…" Began Carly

"Yeah." I said

"In a few days time, I will have to kill someone so I don't go evil again. Since we're both going crazy I want you to promise me something. Clary and Simon must not know about it. Deal?" Said, Carly, with a look of determination.

"Deal. What is it you want me to promise?" I asked

"If I do go evil again, I want you to kill me. I know Simon will be distraught, Clary too, but I can't keep living like this. If I kill again and there is no way around it, I give you permission to kill me. Promise you'll do what is necessary. Please." Said, Carly, with pleading eyes.

I looked her and nodded, "I promise, if there is nothing else we can do I will kill you. Only if you promise to do the same for me. If I go mad, evil, or both, you have to kill me. Everyone else will hesitate and I need someone to be there. I will kill you, if you promise to do the same for me."

Carly looked down at her feet then back up at me, "I promise if you go mad or evil, I will kill you."

Clary POV

After fighting with Carly, I wanted to apologize. When she came back into the restaurant she left; not even saying goodbye. I was hoping tonight would make things go back to normal, but it just made things worse. I know I have been a horrible sister, but I want to do better. If only she gave me a chance.

When we got back to the Institute, Jace wanted to get some rest. I left him in his room so I could focus on the demon attacks. I checked the sensors, but nothing was detected until a little bleep appeared on the west side of town. Izzy and I noticed it at the same time and we knew what we had to do. We collected our weapons and got there as fast as we could. It was something Izzy and I had never seen.

We made our way down a back road when we came upon a creature standing over a woman. From our angle it looked like the thing was shoving some kind of gas down the woman's throat. I got closer and the creature turned its head. I could sense it was a demon, but I had never seen one like this.

Its head was that of a molded, evil looking, owl. His eyes were 2x bigger and as black as a starless sky. It stepped off the woman with ease and turned its full attention to us. The demon began to walk forward, but stopped as if a force was holding it back. It screeched and jumped on top of one of the buildings; disappearing.

I wanted to go after the beast, but Izzy told me we should focus on the woman. I nodded in response as we crept forward. The woman was lying still, but you could feel the evil shrouding her. Isabelle got beside her and checked for a pulse. The second her fingers touched the woman, she opened her eyes.

She looked up at Isabelle and her face turned sour. She yelled and tackled Izzy onto her back. I grabbed ahold of the woman's arms and pulled her off. The woman fought me, screaming at the top of her lungs. Isabelle took a tranquilizer from her bag and injected it into the woman. She relaxed and collapsed into my arms.

Isabelle and I carried her to the Institute. We informed Alec of the situation and he helped us get her into one of the cells. Alec locked the cell door while Isabelle and I watched from the one sided glass. The woman woke up and began rambling; she looked insane.

"What exactly did you see?" Asked, Alec, coming to stand beside us.

"Clary and I found a demon standing over this woman. It looked like he was forcing some kind of gas down her throat. When it noticed us it turned around and I have never seen a demon like that. It had the face of a deformed owl and the body of man. This demon allowed another to possess this woman. I don't know how he did it, but somehow he did." Said, Isabelle, staring at the woman pacing back and forth.

"He must be apart of the demon attacks. That is why so many are being possessed and killed. This owl demon must be apart of it somehow." Said, Alec, as confusion spread over my face

"I thought there were only two possessions." I said

"Right after you left a man became possessed on the east side of town. He killed his wife and vanished before we could catch him. This is the third out of many to soon happen. If the pattern continues: the people will become possessed, kill a loved one, and then go somewhere I do not know. This is bad, very bad." Said, Alec, with worry.

"How did the demon get from one side of town to the other within minutes? It doesn't make sense." I said as Isabelle and Alec agreed

"None of this makes sense. All we can do is hope we catch this owl demon off guard. We took one of its victims, allowing us to hopefully learn something. Until we have another shot all we can do is wait." Said Alec

"Are we going to interrogate the demon inside her?" Asked Isabelle

"I am going to get ahold of Magnus so he can help us figure this out. After finding out what we need to know Magnus will hopefully be able to get the demon out. I just hope we're not too late to save her." Said Alec

"There is nothing you can do, shadowhunter. She is gone and there is nothing you can do to save her. Hahaha. My master needs me and keeping me here is defying orders. I must goooooo, hahaha. Before you anger my master." Said, the possessed woman, in a sing songy type of voice.

"Who is your master?" I asked

"Someone you will meet very soon. They are going to win and there is nothing you can do about itttt. They are more powerful than you can imagine. They need meeee, so I must go. You will let me go. Hahaha." Said the possessed woman

"You aren't going anywhere. We are going to save the woman instead of you. You aren't leaving this cell." Said Isabelle

"You can't save her, hahaha. She must kill her sister so my master has what they need. If you do save the woman she will already be damned. How can she forgive herself for such a terrible act? She is a goner, hahaha." Said the possessed woman

"She isn't going to kill anyone because you aren't leaving." Said Alec

The possessed woman got closer to the glass and smiled, "Are you sure I haven't killed her sister already? You saw me possess the woman, but that doesn't mean I hadn't been her before. I could've already ended her without blinking, without thinking."

"We would know if you did." I said as the possessed woman turned toward me.

"Would you? Hahaha." Said, the possessed woman, going farther into cell.

"Do you think she killed the sister?" Asked Isabelle

"I will get some shadowhunters to look into it. Meanwhile I need you both to track this owl demon. You are the only ones who have seen this thing in person. Make a sketch and get it to every hunter you can. If we're gonna stop this thing we need all the help we can get." Said, Alec, as we all looked down at the woman condemned to darkness.

Carly POV

After dinner, my situation with Clary was worse. Before, I hated myself for what I had done and I was worried about her hatred. Now I hated both of us, for my acts of evil and how Clary mistreated me. I tried to ignore the fight and just focus on the now. Neither Simon nor Clary knew of what happened in the alley and I was glad; worrying is something I did not need right now.

When we arrived back at the boat house I began feeling this sharp pain in my side. It started out as an ache, but then it got dramatically worse. Ever since I fed on Jace I felt different, odd even. That wasn't all, when I drank Jace's blood there was something off about it. Like a darkness had tainted it.

I could sense something was wrong with him, more than nightmares and hallucinations. Whatever happened at Lake Lin caused this darkness. The blood was reacting badly to me and I tried to hold back my pain. Luckily, I was a good actor in hiding my pain and feelings.

Simon and I arrived at the boat house when we became surrounded by werewolves. We tried to continue past, but they moved in front of every direction we tried to go. I knew they weren't happy about a vampire living near their den, let alone two. So this was bound to happen, but now was not a great time.

"Hey, guys. What's up?" Asked, Simon, in a awkward tone.

"We want you both to leave. Having vampires this close to us, is making us sick. Pack your bags and we won't have any issues. We'll leave you be and you can just get out of here. No fuss from our part." Said Russell

Simon looked at me and then back at them, "We have nowhere to go. I know you guys hate having us around, but we stay out of your hair. I might visit Luke at the Jade Wolf, but we don't want to cause trouble. All we need is a place to sleep."

"We know that, Simon, but we don't want you here. The smell of you guys is making us cringe. You are going to leave and you are going to leave now. If you don't leave by choice, we can make you leave by force." Said, Russell, as wolf beside him growled.

"Does Luke know about this? How you are trying to kick us out?" I asked grasping my side with little notice.

"He doesn't need to know if you go quietly. Luke has gone soft because your family, but we're his family too. He needs to look out for us and you being here is going against that. Luke needs to focus on his priorities which does not include either of you." Said Russell

"We are not leaving." Said, Simon, as I surprised by his sudden confidence.

"So be it." Said, Russell, as the wolf beside him ran at us. Simon pushed me out of the way as the wolf swung his fist toward Simon. When the werewolf's fist was an inch from Simon's face, a rune appeared on Simon's forehead. When it did, the werewolf was thrown 20 feet back into a truck.

The other wolves backed away from Simon as the symbol began to disappear. I took note of what it looked like and walked back over to Simon. Everyone stood there in utter surprise, but not as much as Simon. He had no idea what just happened. He didn't even touch the guy.

Lilith POV

Things were not going as I first planned. Two of my disciples have completed their mission, while the third was captured. My favorite disciple wanted to attack the shadowhunters, but I held him back. Revealing who he was, was not part of my plan, yet.

He returned to me with a bow. I nodded in response and began to talk, "You failed tonight, but we can remedy that soon. I need 29 more disciples and the one at the Institute must be moved to a new body. We can't have people figuring out my plans, just yet."

"As you wish, my lady." Said, the owl demon, in a gruff voice.

"You don't need to hide with me. Show me your face." I said as the owl followed my instruction.

He stood still as his mask slowly came off to reveal a man underneath. His hair was blonde, his eyes two different colors, and he was built. If he weren't my son's murderer I would have let him live, but that is not how the cards fell. I got closer to him and looked up into his eyes.

"You are strong willed, Jace Herondale, but you will not come out on top this time. You will do my bidding and when my mission is complete, you'll die. I will make you watch everyone you care about wither and die, then I will end your suffering. Kiss me." I said as I grabbed ahold of his head.

I pulled him in close and began to kiss him. As I did more of my demonic energy entered his body. Making him stronger, faster, and meaner. The real Jace would began to slowly fade away so he can no longer fight me. I pulled away from Jace and he bowed once more.

"Thank you, my lady." Said Jace

"Return to the Institute and be ready for when I call. There is much to do and little time to accomplish it. When I call upon you, you must follow. Or more people you care about will die. See you soon, Jace. Very soon." I said as he left my house with a blank expression.

Jace POV

I woke up laid across my bed, but I have no idea how I got there. I remember getting some rest and then going out for a much needed walk, but after that my memory is blank. I have no idea where I went or how I got back to the Institute. Something was seriously wrong. I needed help.

I wiped the sweat from my face as Clary came in to check on me. She noticed the terrible state I was in and came closer, "Are you okay?"

"No, I am far from okay. I've been hallucinating the last few weeks and having nightmares whenever I close my eyes. I can't sleep, eat, or concentrate. I went for a walk earlier this evening, but I don't remember coming home. I don't even know how I got here." I said putting a hand through my hair.

"What are you saying?" Questioned Clary

"I think I'm losing my mind." I said as she brought me in for a hug. I broke down my defenses and cried into her shoulder. She held me close as I continued to cry. Whatever is happening to me I do not know, but I think I've gone insane.
