What are twins for? (Book 1) (Mortal Instruments)

Secrets and Lies

I wake up to the sound of my mom and Luke leaving the house early in the morning. I quickly get up and check on Clary seeing her awake. She doesn't notice my presence with earphones in her ears sketching. I close the door and quickly grab a change of clothes before going to the bathroom. I take a quick shower and change into a black tank top with black leather pants. I go to my room drying my long pale blonde hair with a towel. I throw all my seraph blades into a duffel bag as a phone rings in the house. I throw my practice gear and a change of clothes with my toiletries in the duffel bag. I run a brush through my hair to get the tangles out of it before pulling it into a tight ponytail. I go into the living room and set my duffel down next to the door as it opens. I look up to give Luke a smile as he puts some folded boxes down. I walk behind Clary as he looks for something in the tool box.

"What would you do if you saw something nobody else could see?"

Luke drops the tape gun he found as I stiffen up. I haven't had the chance to tell my mother about this yet. He looks to me and I put a finger to my lip.

"You mean if I were the only witness to a crime, that sort of thing?"

"No. I mean, if there were other people around, but you were the only one who could see something. As if it were invisible to everyone but you."

I quickly go to the front door and race down the steps. I stand outside watching for my mother to come down the sidewalk. I know that once she knows about what happened last night she will be worried. Well more worried than she has been lately. I was hoping that Clary would forget overnight, but that doesn't seem to be the case. Suddenly she comes over and I take a step forward.

"Mum we need to talk. Something happened last night that you should know about."

"Later Jade. I need to speak to your sister about our vacation."

"Of course you haven't told her yet. I have practice if something is wrong you call me okay?"

"Alright."

I go upstairs and grab my bag as she sits next to Clary. I quickly walk to the Institute and go up to the training room. For about an hour I practice with my katanas that I leave here before I am interrupted. Jace comes into the room and stops what I am doing. Irritated I turn to him and he gives a smirk knowing that I am upset now.

"I want to go do an investigation without anyone knowing. Want to come?"

"Why not it beats practicing for the next few hours."

I strap my katanas to my back and follow him. We quickly leave the Institute before walking around. It seems aimless and at one point I see Clary and Simon. I move out of their sight and quickly put on a glamour. Jace raise and eyebrow seeing me do this. I shrug with a smirk before tightening my ponytail.

"Sorry forgot to activate it when we were leaving the Institute. Don't want the Mundies to see me and my katanas."

"That's fine. Give me a second because I think our person just passed by."

"Fine."

Eventually he takes off in Clary's direction and I frown. After a few minutes we stop outside a familiar place. I see Simon and Clary both eating inside Nacho Mama causing me to squint my eyes. Her phone rings and she frowns at it before listening to the voicemail. A few seconds later my phone goes off and I see my mum is calling. I pick it up and she immediately starts speaking.

"Jade your sister took off with Simon. Later if you have time can you check up on them."

"Don't worry mom I'm already looking at them. I'll bring her home safe."

She hangs up immediately and I stash my phone looking up. Jace has an eyebrow raised looking at me. I sigh looking at Clary, but know he'll ask later. I might as well get it over with right now.

"My mom adopted a little girl who is a year younger than us. She took off and my mother is worried of course. That's all Jace."

He grunts as Clary looks our way causing me to shift in a way she can't see my face. Jace's eyes narrow, but he doesn't question my motives. I breathe a sigh of relief and we wait as he keeps an eye on whoever he is watching. Come to think of it he never told me who we were trailing. It could be anybody or anything. Why he is keeping it a secret I don't know, but I can't say anything. I'm hiding a young shadowhunter and an adult shadowhunter from the Clave. If anyone I have the biggest secret there is. I get a sick feeling in my stomach as if my body is saying something bad is going to happen.

Last time I had this feeling I was ambushed on my patrol. I luckily got rid of the demon quickly, but had to hide it from Clary. I had scrapes and bruises I had to heal before going home. Sometimes I wonder how good of an idea it is hiding all of this from Clary. I mean shadowhunting is in her blood and it's her birth right, but my mother is scared of something. I also wonder sometimes what would happen if I just stayed at the Institute and never come home. My mother and Luke would understand that it is easier for me, but Clary wouldn't understand. Being the type of person she is she would start looking for me and get herself hurt in the process. I have to stay home for her safety.

Suddenly Jace stands taller and I hear the ding of the bell on the door. I look over and see Clary with Simon coming out. I sigh before turning away and pretending to mess with my phone. Once they pass us I put it away and see Jace following them. Realising that we have been following her this whole time I catch up to him. We follow them at a discreet distance, but keep an eye on them. Eventually they stop and we look at our new destination before entering and sitting in a corner of the establishment.
