A/N: Hello, thank you to everyone who has liked and reviewed so far! It's quite motivational, you know :) and apologies for the late update. I had some laptop difficulties, and had to rewrite this whole chapter. I keep thinking I preferred version one...but hopefully this will do. Also, I started a new job a few weeks ago, so my brain has been a little fried, so writing has been going a tad slower. Anyway, I hope you enjoy this chapter.

Jon POV

We're back at the institute, handing in our mission report. My head is feeling better. Izzy and Alec found me just as I was regaining consciousness. After my blackout, I sat up and looked around, all evidence of the fairy and the candle ritual were gone, so was the greater demon. The siblings made sure that I wasn't hurt. I queried if they saw anything, but they assured me that I was already coming around just as they found me, so I made the decision not to mention anything. The whole Valentine thing was freaking me out. I told them that someone knocked me out just as I was entering the room. They seemed disappointed that we were going back empty handed, but happy that I was ok. I was in the perfect position to hide the appearance of this demon guy. I will find him and find out his connection to my father. And the plan for me, whatever he meant by that.

"Help!" We turn around simultaneously.

There's Jace, stumbling into the institute. He's carrying a shape. He falls on his knees. I see red hair and my heart literally stops. In front of him on the floor is an unconscious and severely injured Clary. Panic flows through me like ice. I run over and slide to the floor next to her. There's blood. It's everywhere. There are deep gash wounds on her abdomen, arms and legs. "What happened," I scream at him. Fear, like nothing I've ever felt before is turning me to ice. I can't breathe. I want to fall apart at the sight of Clary hurt. I take out my stele to start applying iratzes. It's not like I can use my demon blood here, so starting with the healing runes is a good bet.

Jace grabs my hand to make me stop. I look up at him angrily and snarl, "What do you think you're doing?"

He looks positively disturbed. "It...it won't work. I've tried."

"What do you mean it won't work, Jace?" I growl.

"It's not healing the wounds and every time I've applied a rune, it seems to make her cough up blood. I've tried a few times and it's done it every time. Trust me. Ok?"

Izzy and Alec are shouting, but I've tuned them out. All I hear is "Clary" and "Healers." I see Izzy pulling up Clary's bloodied top and the wounds on her belly look horrendous. I feel sick. She's dying. I know she is. I need to take her away and use my blood to heal her.

But I'm losing it. I look at Jace. I see red. It's his fault. Why did I agree to let her go with this oaf. There's another voice at the back of my head, telling me that this is my fault. But I ignore it, I don't think, I move towards Jace with murder on my mind. I pin him to the wall by his throat. He's choking. Good. I'm going to kill this fucker. "What did you do?" I scream at him. I can hear my voice sounding rather demonic. "I will kill you if she dies. You hear me?"

Suddenly I'm being swooshed backwards through the air. I land on my back on the other side of the room. "None of that Jon," I hear Magnus reprimanding me.

I'm infuriated, how dare he? I see Alec checking on Jace who's wheezing on the floor. Izzy is trying desperately to cover Clary's wounds that are seeping blood. Magnus approaches the girls. "Hmmm looks like some kind of undead poison." He takes out a vial and moves it towards Clary's mouth.

I grab the warlock's arm, "What are you giving her?" I demand.

"Relax, relax little trouble maker, only something to slow the poison from spreading." Then he adds, "I need someone to go see Raphael, he's the head of the Night children's clan." He looks at Izzy. "You should go. He'll appreciate a pretty face. Tell him Magnus sends you. Tell him he owes me a favour. Ask for the undead antidote. He'll know which one. Bring a vampire back with you for insurance."

Izzy looks at me desperately, "Jon, I won't be long. Promise." I nod. I'm still heaving from the rage. I see her leaving. Be quick.

I pick up Clary and carry her to her room. She feels so tiny in my arms, my heart aches. I will lose her. I lie her down on the bed. She looks so pale. She's going to die and it's my fault for abandoning her. "Jon, she's going to be ok. The medicine I gave her will slow down the poison and once Izzy returns, I'll give her the antidote and it'll be fine. She will live." I feel Magnus putting his hand on my shoulder. I shrug him off. I can't have anyone touching me right now. Then I hear steps coming this way. Jace. Fucking Jace.

"Jon. I'm sorry man. It was ten vampires. We were outnumbered. And...and Clary had my back. She saved me, man. I wouldn't be here without her. Please. I feel really bad. You have to know that!"

I look at him calmly, but inside I'm anything but, keep it together. Slowly I respond, "Jace. If she dies, or if she even gets the slightest bit worse. You'd wish those undead killed you. Because I...I will take my sweet time with you. Now leave. Before I lose my shit completely," I snarl at him. Jace looks upset. I see him looking at Clary. "Don't even dare look at her. GO. Before I change my mind you idiot." Jace looks like he wants to say something, but makes the decision to leave. I see that he has some brain cells left in that thick head of his.

I look at Clary. Her breathing is raspy. The blood is still oozing from her wounds. I grab a first aid kid, yes Clary has one, god knows why. I grab something that looks like it would clean wounds and some gauzes and start cleaning and covering her wounds. But it's not doing much. Her blood flow is slow, however, it's constant. She doesn't have much longer. The thought is unimaginable. A world without my Clary? I'd rather be dead myself.

I lean down to breathe her in, to assure myself that she's still alive. I sit next to her and take her hand, stroking her hair. Please Clary. Please come back to me.

"You have quite the Shadowhunter temper, don't you?" I look up and see Magnus studying me. "If I didn't know any better, I'd say you meant what you said to Jace, 'That you would take your sweet time with him.' "

I look at him again. See him studying me. Does he know? There's no way. I give him what feels like a warm smile, "Magnus, relax. I was half joking." He seems skeptical, but I think he believes me for now, so he sits down. We sit like this in silence for what feels like an eternity. I keep close to Clary, holding her hand and stroking her hair. Please be ok little sister.

Finally I hear Izzy and rush towards her. "I've got it!" She's hyperventilating, "I've ran the whole way, and brought this undead guy, too," she points behind her.

"Hi everyone, I'm Simon," I ignore the vampire imbecile and take the vial.

Magnus grabs the antidote from me, "Marvelous," he unplugs the apothecary bottle and sniffs it. "You," he waves the vampire guy over. "Yes, you."

The vampire walks towards the bed, Magnus grabs his arm and slices it. "Man, was that necessary," he shrieks to the Warlock and Izzy stumbles back in shock.

Magnus seems to be in a magic zone, he doesn't respond, just holds the bottle underneath the vampire's arm, collecting a few drops of the blood and chanting under his breath. I realise what he's wanting to give my sister, "Fuck, Magnus. You are under no circumstance giving any of THAT Vampire blood to my sister!" I wave in the direction of the substance. I'm rushing towards him, but he magically freezes me before I can reach him. I cannot move.

"None of that Jonathan, get it together. This," he points to the bottle, "Is the antidote and only a few drops of vampire blood can activate it. So stay calm my angry Shadowhunter. I'm going to unfreeze you now, all right. One drastic move from you and I may decide to send you to Edon until you cool your angry socks. Understood?"

He looks at me patiently and all I can think of is Clary. I nod hesitantly, "I hope I won't regret this, warlock."

I make my way back to Clary and take her hand and start placing little circles on the back of it. You will wake up.

Magnus bends over her little form and gives her a few drops of the antidote followed by some magic hand waving. Izzy, and the vampire called Simon are in the background, whispering, but all of my attention is focused on my sister. "All right, this will do," Magnus says cheerily. "Now, it'll take a few hours for the poison to dissolve completely, and for her wounds to heal. She'll wake up as soon as her body is fully healed."

I barely pay anyone any attention. All of it is on Clary. "Jon, do you need anything," Izzy asks from behind me.

I shake my head. I want to be alone with my sister, so I add, "I'm going to stay here until she wakes up. You guys go. I know it's late."

"But we don't mind," Izzy stutters from behind me. I want them all gone, now.

"Just go." I realise the words came out too harshly, so I add a hesitant, "Please. I will get you when she wakes up, OK?"

" We will, but promise that you will get me, as soon as she wakes?" Izzy asks desperately.

"Yes!" I grunt.

I hear them all moving towards the door. "Jon. She'll be ok. I promise."

I look up at Magnus and mutter, "Thanks." He smiles at me and leaves the room.

I'm still focused on Clary and notice that she's still dressed in the soiled clothes. I get some towels from the bathroom and a bowl with warm soapy water. I move towards her. She looks so small and delicate in that big bed. Her hair hangs in messy waves around her. She's so pallid looking, it breaks my heart, if only I had one. This is my fault for ignoring her, for not insisting that she'd go with me. My fault. I pull her up and take off her top. I remove the already bloodied bandages. The wounds are slowly healing. Good. I soak the cloth and start wiping her clean. I cover her wounds with fresh bandages. I grab a clean top and put it on her. I then strip her out of the muddied and ripped jeans and wipe her legs clean. I'm so concentrated on my task, all I can think of is for my little sister to be ok, so much so that her nakedness isn't affecting me. Stripping her out of the clothes is only a task that I'm completing. Nothing else. I cover the wounds on her legs and put some pyjama bottoms on her.

Then I lay down next to her and gaze at her. I take her in. Her beautiful little form. This. This situation. Clary's almost death. It is my fault. It's karma getting me. It's the universe punishing me for my actions. It's because of my sick fascination with my sister, it's the love I harbour for her. It's my demon. It's the blood I've spilt. It's the innocent girl I raped. It's my actions afterwards, ignoring the one person I love in this world. Making her feel unimportant. How will I fix this? How can I? I need to find a way. I contemplate everything that has happened these past few weeks. What I don't understand is why now. I've been fine all these years. Well not fine like any other normal person, but I've never felt this intense, all consuming longing for Clary's body and soul, so why now? I go over it a million times until the sun rises, but still Clary hasn't woken up.

CLARY POV

Everything hurts. It's dark and I can't see. What happened? We were overrun by vampires and I fought and fought, but they kept coming and then everything went black. I slowly open my eyes and regret it instantly. The bright light is hurting my eyeballs. A painful moan escapes my lips.

"Clary?" It's Jon. He's here. He's really here. Relief washes through me. I slowly open my eyes again and see him staring at me. My mouth is so dry, I can't speak. It's like I've lost the capability to form words. "You're OK Lily? My sweet Lily?" He looks at me with sheer relief and love in his eyes, the next second he's covering me with his body and I can hear a wailing. Is there an animal in the room? But no, the sound of agony is coming from my brother. He's broken down crying. "I'm so so so sorry Clary. Please forgive me."

He continues to cry and I lift my hand to his head and start stroking my fingers through his blond strands. I rasp my throat and only a whisper escapes my lips, "It's ok Jonathan. It's ok. I'm ok. What happened?" He doesn't respond, his whole body is shaking and he's still crying. I've never seen him like this. I slowly prop up and keep his head on my lap. Holding him close and muttering assuring words to him.

I suddenly hear a commotion from the corridor, so does Jon. He jumps up and disappears behind the bathroom door, just as the other door to the hallway opens and Magnus enters my room, followed by Izzy, Alec and Jace. Jace runs towards me, "Thank Raziel, you're fine." I look up at him and see huge welts across his neck.

"Jace, what happened to your neck?"

"Oh this? It's nothing."

"It was Jonathan."

I look up at Alec who just accused my brother. "What do you mean it was Jonathan?" I look at Jace incredulously. "Has he hurt you?"

"I told you to stay away from her!" Suddenly Jon is here, moving towards Jace like a predator. I'm too stunned to react until he has Jace pinned against the wall. I jump up and shout at my brother to stop, but he doesn't hear me. My knees still feel weak, but I can't let Jon hurt anyone, not for me. Besides, it's not Jace's fault and even if it was, he has no right. No right. How does he go from crying to this fury in less than sixty seconds?

I can hear Alec from behind me, "See, that's what I mean. He almost killed him last night, he blamed him for the state you were in and look at him now! Your brother has gone mad, Clary." I want to snap at Alec to shut up, but I bite my tongue.

"Stop exaggerating Alec." Izzy snaps at him and I'm thankful.

I decide to ignore them, I only see my brother now. I move towards Jonathan who still looks like he may kill Jace. I grab his arm and pull him back with force. He growls at me like an animal would. Then he recognises me and stills instantly. His eyes are still black orbits and anger shapes every angle of his handsome face. He looks evil, that's how I would describe him, but he doesn't scare me. He could never make me fear him. I love him too much.

"Look at me Jon." He turns his onyx eyes towards me. He's still seething, I can see it. "How dare you hurt Jace? He is innocent. You hear me? Only I am to blame for what happened."

His fists are clenched. "It's his fault you got hurt. He should pay for this."

"No, Jon. No, he didn't do anything. How dare you hurt our friend?" I point towards the door angrily, "Just leave and don't come back until you've calmed down. You hear me?"

A/N: poor Jonathan, but Clary is ok. And yes, Simon has made an appearance, I'm not quite sure yet how to weave him into the storyline, so for now he only has a little 'cameo' role.
