Hi! This is my new story I'm working on. After I read the first book 2 years ago, this has been stuck in my head all this time. I only just decided to start writing it now because it was taking up most of the space in my head and I couldn't think of stuff for my other stories.

Disclaimer: I don't own anything from The Mortal Instruments series. The characters, items, and everything else all belong to the amazing Cassandra Clare (both she and Stephenie Meyer are amazing writers in my opinion.)

Summary:
What if Jace went with Valentine through the Portal in CoB, and a few years later, found out he wasn't Clary's brother? What if he came back after? How much has Clary changed in those few years apart, and how will she take it knowing that they aren't related at all?

Ch. 1 Jace's POV

It seemed like it has been centuries since I was on these ground last. The Institute still looked exactly the same, standing tall and proud as it was safely hidden from the mundanes with the glamour that was placed on it. The Gothic cathedral structure with tall towers seemed to pierce through the clouds that were turning pinks and gold with the setting sun. I almost forgot about why exactly I had left this place for, but then I remembered; Valentine.

I felt the anger that I was holding in seemed to grow at the mere thought of him and what he had done to me; how he had tricked me into thinking that I was his son, and how he convinced me to follow him into Idris. How he tricked me into leaving behind the Lightwoods and Clary.

God how I missed Clary! All this time I thought I was her big brother, and I felt so wrong about my feelings for her. It had only been a short while ago that I had found out the truth.

Flashback

"Alzric!" I ordered and not a second later did the warlock appear. He looked like he would have been no younger then I am, with skin a deep, dark color, as though he had been out in the sun for too long, and long hair that looked like the color or an oil slick. He would have looked like an ordinary mundane, if not for his eyes being completely black and the electric blue wings producing from his shoulders.

"Yes, young master Johnathan?" the warlock spoke as he bent so low that his nose could have touched the ground. I held out a large brown envelope to him.

"I want you to send these to a hospital, whether it be mundane or one of our own, I don't care. The following instructions that are inside are not for your eyes to see. If I find that you have read them, and trust when I say that I will, I shall prove to you that my father is not the only one who knows how to torture your kind," I hissed out the last part so dangerously that I had him cowering before me. He raised a shaking hand and grasped the envelope, turning to leave.

"And you will tell no one of this- including my father. Is this understood?" I threatened. Alzric nodded obediently and then disappeared into thin air

End Flashback

That is how I found out about the lies Valentine had told me. With a DNA test coming back negative for a parent/child match, I found the truth- I was not Johnathan Morgenstern. If I really was Michael Wayland's son, I did not know. But that mattered little at the moment.

Now, after finding the perfect escape from Valentine's manor, I was home. As I walked up to the doors to ring the bell, two figures appeared in the doorway, each heavily armed and dressed in basic Shadowhunter gear. I recognize the heads of pure black hair anywhere.

"Izzy! Alec!" I exclaimed joyfully as I began to walk faster towards them. But as I got closer, Isabelle lashed out with her gold whip and snapped it tightly around my ankles, pulling me to the ground with a hard thud. When I pushed myself up and turned around, I found an angel blade pointing directly at my throat.

"Guys, it's me- it's Jace!" I said as I held my hands up in surrender.

"Prove it," Isabelle hissed.

"Fine; Isabelle, your motto is nothing less then seven inches when it comes to shoes, your cooking is absolutely terrible, and you love the color purple. Alec, you've never been able to kill a demon before, you dislike spiders, and-"

"Ok, we get it," Alec said as he pulled the blade away from my neck and sheathed it and Isabelle untangled the whip. As I got up on my feet, I was almost knocked back down again as Isabelle plowed into me.

"I'm so happy to see you Jace!" she squealed as she hugged me to death. I returned the gesture and gave a hug to Alec as well.

,:~:,

We were all sitting in Izzy's room, and I realized that it hasn't changed one bit. Same bright colors, same giant mess of clothing; everything.

"So let me get this straight," Alec started. "You got a DNA test, found Valentine wasn't your dad, and then you left in the middle of the night and came here?"

"Yeah, and I'm relieved about it. Where's Clary, by the way? I want to tell her the good news," I said happily. At the mere mention of Clary's name, both siblings paled in color and turned to look at each other.

"Well… Jace, there's something you should probably know-" Izzy started up, but a knock on the door caused her to stop and turned her head as it opened.

"Hey Izzy, you in here? I was wondering if you knew where-" the voice said and I turned to see who it was, and I was stunned.

There, standing in Shadowhunter gear and the jacket open to reveal a black tank top, was Clary. Her red hair had grown longer and slightly darker, she stood taller- maybe almost my height- and she filled out in all the right places. She had a few weapons in the belt she was wearing and a whip like Izzy's was wrapped around her left arm. Beside her was the electric blue cat Church.

"Well, well, well. Look at what the cat dragged in. No offense Church," Clary said as she bent down to scratch at his fur. Then she straightened up and walked over to us, wrapping into a hug. I returned the gesture, feeling so happy to have her in my arms, where I was determined to keep her. "Hey there big bro. How's it going?"

"I'm good. I'm really, really good," I said as I squeezed tighter. But as I did, she pulled away.

"Careful!" Clary squealed as she pulled back. "I'm still a little messed up from earlier. Damn Forsaken downtown threw me into a brick wall."

"Are you hurt?" I asked as I checked for injuries, but couldn't see any.

"Yeah, I'm good. Takes more then some lame-brain creature like that to get me down," she said proudly.

"So did you get it?" Izzy asked.

"Damn straight! Oh, and thanks for the ring Iz. Worked like a charm." Clary raised her right hand to show a thick ring with black runes of strength and speed on her index finger. But what really caught my eye was the one on her actual ring finger; an Irish claddagh with an emerald stone centered as the heart… that was pointing inwards. (AN: A claddagh is an Irish ring that represents relationships. On the right hand, if the heart points to your wrist, it means you're in a relationship.)

"Where did you get that?" I almost whispered as I pointed to the ring. Clary looked at her hand in confusion to what I asked before letting out a small laugh.

"Oh, this! It's from Simon!" I didn't like how she said the mundane's name. "That reminds me Iz- you know where my fave top is at?"

"You mean that halter/corset one? The dark green one?" "Yeah, that's the one." "It's in the laundry room. Mom washed it for you the other day."

I looked at Clary nervously. "What are you talking about?"

"I'm going out tonight. I've got a date," she answered, and I felt that the world had stopped.

Clary? On a date? A part of me should be happy for her. She was able to move on with her life. But all I felt was pure torture. How could she have forgotten me that quickly? As I looked at her face, I noticed that there was a small scar along her throat. Where did she get that from?

"Yikes! I gotta jet! I'm gonna be late!" Clary said as she looked at the clock by Izzy's bed before she ran out the door and down the hall.

"What the Angel's name was that about?" I turned to ask the two Shadowhunters before me. Alec looked away, almost scared by me, but Izzy stood her ground like she usually did.

"You remember Simon, right?" I nodded at her question, starting to feel impatient about this. "Well, a couple weeks after you left, Simon was attacked. A mundane mugger in some dark alley. Anyway, Simon still had blood in his system from that vampire when he was at Dumort, and he was badly hurt from the mugger. He turned vamp.

"Simon's still a great guy!" Izzy quickly added at my terrified expression. I wasn't scared for myself. I was scared for Clary. I didn't want her to get hurt. "And the weirdest thing is he's able to walk in the sunlight!"

"How is that possible? All vampires burn in sunlight!" I nearly shouted as I shot up from my seat.

"No clue," Alec said finally. I nearly jumped again when I heard him; I forgot that he was even there. "All we know is that he can, and there are plenty of vamps that want his head on a silver platter."

,:~:,

"A vampire, Clary? A vampire?!" I asked to the door of her bathroom. I was sitting in Clary's room, waiting for her to finish getting ready for her date tonight. The walls were painted a deep purple, but were covered by at least a dozen posters from magazines. The bed was neatly made, not a hair out of place, and the clothes in the open closet were perfectly arranged.

"Yes, I know he's a vampire Jace. I'm not dumb, jackass," Clary said as she opened that door. When she did, I thought my jaw hit the floor.

Clary was wearing a deep green halter corset shirt and black leather pants that hung low on her hips. She had a pair of black stiletto boots which reached up to her knees and looked like they were at least three inches tall, silver and green metal bracelets around both wrists, and silver hoops in her ears. Around her neck was black velvet choker, with a silver bat-winged emerald, and on her hand was the claddagh and Izzy's ring. Her eyes were lined heavily with black eyeliner and dark green eye shadow.

"What are you wearing?" I asked as I raised a shaky finger. Yes- shaky; that outfit was way too sexy for her to wear out in public.

Clary looked at herself in the mirror beside her and looked back at me confused. "It's called an outfit Jace. I'm going to Pandemonium tonight. Major party and I need to dress to impress after all."

"No way! You are NOT going out like that!" I yelled at her. She just simply shrugged and muttered 'whatever' before heading to the door. She didn't even take two steps before my hand lashed out and wrapped around her arm.

"Clarissa Fray, you are not going out with that leech looking like that!" I yelled as I spun her to face me. When I did, I was lucky that I ducked just in time, because her fist would have made contact with my face.

"Fuck you Jace! You may be my brother, but I don't give a shit!" she shouted at me as she walked closer with a deadly look in her eyes that had me backing up.

"Simon may be a vampire, but at least he didn't just ditch me when I needed a friend! Maybe you may not realize it, but Mom's still in the hospital, Valentine's still at large, and he has two of the Mortal Instruments! Add that to the fact that my memories of all this shit were only starting to come back at the time, and I needed to begin my training, and you get one very fucked up life!

"Simon was there for me, and I care about him. He's the best boyfriend a girl could ever have and he would never do anything to hurt me. So don't you dare insult him, or I swear to the Angel that you'll regret ever meeting me!" And with that, she grabbed her jacket from the back of her desk chair and walked out of the room.

I stood there stunned for a moment before I snapped out of it and ran after her. But with my hesitation, Clary was already too far ahead, and I caught up with her just as the elevator was descending. I slammed my fist into the wall beside me and looked out of the window there.

Out on the street was a boy, who I realized was Simon dressed in a dark green shirt, jeans and a leather jacket, on a pure black motorcycle. I heard the doors to the Institute open and slam close and noticed Clary run up to him and wrap her arms around him, pulling him into a kiss. I felt the rage in me intensify and watched as she then jumped on the back of the bike and they sped off to Pandemonium.

So here's the first chapter. What do you think? A good story idea or a total flop? Please review and give me your honest opinion- criticize me, tell me it's terrible if you want to, but please be honest with me.

Thank you!!
