Our demon walked along the street, fear coating his features at him being followed. He stopped in front of Alec and looked behind him before moving on. Alec turned and followed him before leaping out of sight as the demon turned and stared behind him again. He began walking again and Iz and I moved to follow him on opposite rooftops as he bumped into a man's shoulder and transformed into him. We continued following him until I joined my brother's side before he bumped into a woman in a purple and black dress. We waited for Iz and Alec to join us before jumping down from the rooftop and follow, unseen, into the club Pandemonium. Well, we thought we were unseen.

"Hey would you watch where you're going?" a redhead asked him after he bumped into her shoulder. Jace and I shared a confused look before looking at her.

"You can see me?"

I grabbed my jacket and made my way to where my twin was waiting for the rest of our team.

"Isabelle, let's go!" Alec called out to his sister.

"Hey, there, big bro," Izzy smirked while playing with her wig.

"Really?" he asked her motioning to the wig.

"Demons dig the blondes," I said flipping my hair behind my bare shoulder before putting on my black leather jacket.

"Of course they do, but that's white," Alec pointed out.

"Platinum," Iz and I corrected him.

"And they don't exactly like Shakespeare, okay, Alec? Izzy asked her brother.

"You two are plenty distracting on your own," Alec told us and I turned to him and walked backward while I spoke.

"So, be yourself. Is that what you're trying to say?" I asked him smirking.

"Nevermind. Looking good, let's go," he told us before we joined Jace in the main hall.

"We're ready to go, Jace," I told Jace and he turned to us.

"Nice choice, Izzy. Demons dig blondes," Jace said before turning back to the screen.

"Told you," Izzy smirked at her brother.

"All right, guys, for some reason our demon friends are killing mundanes and draining their blood," Jace told us.

"Why do they want blood?" Alec asked. "Isn't that vampire territory?"

"I don't know, Alec. Lazy vampires maybe," Jace suggested.

"There must be something special about the blood," I suggested.

"What could be special about mundane blood?" Alec asked.

"You get me a sample and I'll tell you exactly what they're looking for," Izzy told him.

"We'll have more answers when we figure out exactly who the demons are working for," Jace reminded us.

"So, you don't think they're acting on their own?" Iz asked.

"Not a chance," I told her. "They aren't the smartest demon out there, Iz. They're shapeshifters." We went back down the small set of stairs going back to one of the many screens we had on our target.

"This is what our target looks like," Jace said pointing out a picture of an older Asian man.

"For now."

"Great. I'll get the approval for the mission," Alec said as we all took a good look at the demons current shape.

"Come on, Alec," Jace said before moving for the door while running his finger down his seraph blade. "By the time you've sent that message, we'll have killed six demons."

"Besides, it's more fun to break the rules," I told him.

"Than to follow them," Izzy finished my sentence.

"Hey would you watch where you're going?" a redhead asked him after he bumped into her shoulder. Jace and I shared a confused look before looking at her.

"You can see me?"

"Yeah, that's kind of the point," the girl told him. "But you obviously didn't see me."

"Did you even activate your rune?" I asked smacking his shoulder.

"His what?" she asked looking at me.

"You have the sight," Jace stated staring down at her.

"Wait, the what?" she asked him confused.

"How can I not know who you are?" he asked her confused. We had records on all mundanes with the sight, but this girl wasn't one of them.

"Has that line seriously ever worked for you?" She asked him, obviously flirting now. "Even once?"

"Jace! Eve!" Alec called us. Jace and I turned to see him motioning us to follow him. Jace and I stared at her before running into the club.

We followed the demon into the club before splitting up. She walked into a back area, but I turned when I felt eyes on me. I stared at a man who was being fed a drink before walking into the curtained off area before it was closed off from the mundanes dancing at the club.

"Izzy." Iz nodded before moving to a table, taking off her coat and revealing her small, white, leather outfit and took off her wig. She started moving her body seductively, drawing in the other demons in the room as Jace made his way to the woman we followed.

"I hear you've been peddling mundane blood," Jace said to her.

"Why?" She asked him. "Are you looking to score?"

"I'm not," he told her turning her to him. "But you're gonna tell me who is."

"Well, you're outnumbered here."

"Oh, I like our odds," he told her. "Last chance." His blade became bare and I smiled at the demons in front of me.

"Watch out!" I turned quickly in time to see the redhead from before pushing the shapeshifter out of the way of Jace's blade. She turned back to them with her true mouth wide open.

"Careful!" Jace shouted as the girl gasped. I turned back to the demons in front of me. The first one came at me and I immediately pulled my sais from their sheaths and threw one at him. He disintegrated before his friend jumped through him and came at me. I used my one remaining blade and cut at him, but he dodged me and wrapped his arm around my waist, pulling me close to him. He tried to bite me, but I headbutted him and he fell back slightly giving me just enough space to grab my second sai and stab him in the head. Another demon came at me as I made my way to me thrown sai and I jumped back out of reach. He punched at me and I dodged him while grabbing his hand. I pushed his hand back at him, making him hit himself a couple times before kicking him away. I quickly turned when I felt another demon behind me and kicked him in the gut. He grabbed my foot and twisted, knocking me to the ground. I swung around, extending my leg as I did to knock him away from me. I crawled to my sais and threw them both at the two demons surrounding me. They disintegrated and I sighed with a smile on my face. I looked around and saw Jace staring at the curtain cutting us off from the mundanes and the redhead gone.

"Where is she?" I asked him.

"Gone."

When we got back to The Institute I stretched my arms above me. Jace immediately went to the monitors and started looking something up and I shook my head. That's my brother. Always working on something. Then again, that's how we'd been raised. Protect the mundanes from the demons while controlling all emotions and making no connections. Not even with each other. That was, of course, the one rule we didn't follow. We were the only family we had left.

"Go," I told him. He turned and looked at me confused. I tossed him a scrap of cloth that didn't belong to any of us. "Find her."

Two days later, I sat next to the girl as she slept uneasily. I watched her place a hand on a purple stone she wore around her neck and it started to glow. I stared at it confused, leaning down to get a closer look when she lept up gasping and hitting my forehead with hers.

"Ow," I said touching my forehead that had started pounding.

"Wait, I don't know who you-"

"I'm Eve. This is Isabelle," I said motioning to my second oldest friend.

"I've never seen Jace so curious about a mundane," Iz said as the girl started looking around the room she was in.

"Unless he was trying to sleep with them, but even then he's never been this distracted by a pretty face," I said. "But like you saw earlier, distractions are deadly in our line of work."

"I have no idea what you're talking about," she told us. "Who's Jace?"

"You really don't know, do you?" I asked her.

"All I know is some psychos took my mother, and now you people have taken me," she told us and I nodded.

"Nice thanks."

"By taken I assume you mean saved your life?" Iz chuckled.

"You're welcome, by the way."

"A mundane shouldn't be here," Alec said as he and Jace joined us.

"Where is here exactly?" she asked us.

"She's not a mundane, Alec," Jace insisted for the millionth time.

"How do you know that?" Alec asked him.

"Because the seraph blade lit up when she touched it," Jace told him. "Look, Isabelle, can you..." he motioned her to move and she did so. He sighed before sitting in front of her.

"I'm Jace Wayland. You've met my twin, Eve, and our siblings, Alec and Isabelle Lightwood."

"I'm, uh-"

"Clary Fray, we know who you are," he told her.

"Am I the only one who finds this unusual?" Alec asked.

"You find everything out of the ordinary unusual," I commented.

"I have to report this to the Clave," Alec insisted.

"You know what?" Jace asked. "Dial it down a notch."

"My brother doesn't have a dial," Iz joked. "I love you, Alec, but you have a switch that's always on."

"I love you too, but this..."

"Hey, you know what? Give me a minute," Jace told us. "Here's a word you never hear me say. Please?"

"What is with you?" Alec asked him. "Really no, what is with you?"

"Walk with us, big brother." Iz grabbed Alec's arm and together the three of us walked out of the infirmary.

"I'll explain it to you," Iz told him as we back out way back to the main room.

"We don't know this girl," Alec pointed out again. "There's no such thing as new Shadowhunters."

"There is now," Iz said.

"You don't find that strange?" Alec asked us.

"What we find strange is that you're so upset," I said stopping the pair of them from walking.

"Maybe you're upset by the way Jace is looking at her," Iz chuckled. "You know, you should be happy that Jace is interested in someone other than himself."

"I think we all should be," I added.

"Maybe I'm pissed that she's ruined the mission," Alec reminded us. "We never found out who's buying the blood. That was our one job."

"You are such a buzzkill sometimes, Alec," I groaned as he walked away from us.
