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

Ravener

I pull out a seraph blade and quickly whisper an angel name lighting it up as I go into the building. I carefully scan the interior for threats noticing that the light under Madame Doretha's door is turned off. I dismiss it before quietly walking up the stairs watching the door and listening to anything that wants to ambush me. I carefully open the door with my foot and my blade held up in a defensive position. It's too quiet and chills run up my spine, but I ignore them as I continue forward. When I first enter I notice how everything looks normal and nothing is out of place. I see that my mum has not left with her purse or keys causing my worry to shoot up, but I pay it no mind. I check my room and Clary's room, but nothing is disturbed in the rooms.

"Where are you? Mommy!" A familiar shriek cries from in the apartment.

I race out of the room and start looking for my baby sister who has just announced her presence. If anything is here then they know she is here and defenseless. I can hear her footsteps and realise she is in the kitchen, but I am right in my assumption. Something is in here and it's stalking my baby sister. I hear the movement and swear racing to the kitchen. I enter just in time to the Ravener demon fly over Clary's head as she rolls allowing it to miss her by inches.

"Clary run and hide!"

I run after the demon, but it's fast and it races after Clary. She runs into our mum's room and I quickly assess that our mother is not in the house. Whoever came for her found her and took her. That second of thought causes the demon to get closer to Clary and she screams throwing a picture frame at the demon. Before I can move she shoves a Sensor down the demon's throat and screams as the demon venom drips on her wrist. She comes my way and I see it jump on the door frame just as she reaches the door frame. Before I can kill the demon finally it stings Clary before going back to its home dimension. She falls into my arms just as Jace throws himself into the room and Clary passes out.

"Jace pass me my stele!"

"What for?"

"Ravener demon just stung her and luckily it was already half dead."

"Someone is coming we need to hide then we can figure out a way to save her. I'll grab her and you lead us somewhere."

Just as he said Jace takes Clary from my arms and we quickly walk down the stairs. We set up behind my mum's rosebushes as a set of police cruisers comes to the apartment. Jace and I bend low to keep from being seen as I softly swear. Someone must have heard Clary scream and called the cops. At least that's what I think until I get a good look at the police officers and swear colourfully causing Jace to chuckle. I keep an eye out as my sister finally wakes up once more and tries to sit up. I see Jace tending to her so, I watch the fake cops to see if they have any inkling of knowing that we are here. I hear a strangled gasp and turn to see Clary freaking out on us.

"Clary it's okay I'm here and we're gonna fix you up. Jace we need to move now before they realise we're here."

He places a rune on Clary before picking her up and I see her pass out once more. I lead him away from the demons and we begin the long trek back to the Institute. Hodge is going to be so upset when we show up because he doesn't know anything about Clary plus Jace just put a rune on her. I chew my lower lip worried about my baby sister, but I can't show it and I thank the angels that we are glamoured. It would be a weird sight for a mundane to see the three of us walking down the street and we don't have time for us to be stopped.

"Hodge knows we are bringing her to the Institute because he asked me to bring her. He wants to know why she could see us in Pandemonium."

"Yeah well he won't be happy with you over the fact that you just gave her a rune. What if she was a human or downworlders? She could have gone forsaken from the rune."

"I had a feeling she was like us. Not many mundanes have the Sight."

"How the hell did she get to our place anyway? I trusted you to bring her to the Institute."

"Not long after you left she freaked out on me and attacked me. While I was surprised she took off running and I followed her without her knowing, but I lost some time."

"By the angel I didn't know she would do that if I left her with you."

We finally make it to the Institute and Jace takes Clary to the infirmary while I go searching for Hodge. Once I find him I explain everything and he looks surprised at the revelation, but gives me a crooked smile. We both go to the Infirmary where Isabelle has changed Clary out of her clothes that have demon venom on them. The clothes are thrown into the fire so that no one comes in contact with the deadly venom and Isabelle gives me a soft smile. I sigh before running a hand through my hair and sitting in a chair next to Clary's bed. Isabelle squeezes my shoulder before leaving the room and Hodge checks Clary to make sure she is healing just fine. He is obviously furious that Jace put a rune on her without knowing what would happen to her once the rune was placed on her skin. After a while the two leave and I stand up to brush the hair out of Clary's face before kissing her forehead.

"I'll see you when you wake up Clare." I whisper before leaving her side.

I leave the infirmary and find Jace waiting for me. We quietly walk down the halls until he leads me to the room next to Izzy's. I give a small smile of thanks as Isabelle comes out of her room. She hands me a set of clothes considering we're the same size with us being the same height and weight. I smile in thanks to her before entering my room and taking a long shower to get the blood and ichor off. Once done I draw an Iratze on myself and get in the clothes that Izzy has given me. I crawl under the covers on the bed before quickly falling asleep as soon as my head touches the pillow.
