Malignant

"Here it is." I said awkwardly, motioning to the church.

Simon flinched back, "A church?"

I rolled my eyes, "It isn't going to hurt you." Simon looked wary, "There's a warlock inside."

"Are you sure?" He asked, taking a step towards the church.

"Yes, I'm sure. This is the only institute in the world that will hold Downworlder's safely." I nodded, opening the door with the brass key.

"Every Downworlder?" Simon glanced at me.

It was the first time that I realized that Simon was beautiful. Of course, I thought there was a law against vampires who weren't attractive, but he was different. Simon's eyes were chestnut brown and had an almond shape, they made you want to care for him. His curly hair was well-kept and groomed perfectly, his look was so much different than Jace's.

I nodded, amazed. Then I shook my head quickly and opened the door before stepping in and leading him to the elevator.

"So," Simon cleared his throat, "Who lives here?"

I smiled dryly, "Oh, I think you will love the company." I said as the elevator doors shut and we started on our way up.

Two minutes later, Simon and I walked down the long hallway looking for my family and the two I had just met. When we arrived in the kitchen, where everyone was, naturally, I looked at Simon.

"Simon, this is... everyone." I motioned the them, "And everyone this is Simon."

Magnus glared at the vampire, "If you do anything to hurt anyone here, I will light your vampire butt on fire."

Isabelle walked up beside Magnus, "And I'll whip the hell out of you."

"Come on, Clary." Magnus came up to tug me over to him, to get space between Simon and I, "Don't get to close."

"What a warm welcome this has been." Simon smiled warmly at the five of us. Jace glared at him, while keeping one eye on me, and Alec just shrugged.

"Trust me," Alec said, "This isn't the warmest they can be."

"Really? It's very hot in here." Simon took off his jacket in dramatic effect.

"Want it to get hotter?" Alec asked, "They could get your family taken away and then not do anything about it."

"We're working on it, Alec." Isabelle whispered.

Simon nodded, "Listen to your sister, I've only had the chance to talk to one of you and they seem all right." He smiled charmingly at me.

"Sister?" Alec looked shocked and glanced at Isabelle, "She isn't my sister."

"Oh, I'm sorry." The vampire shook his head, "You two just look very much alike."

Alec and Isabelle both glanced at each other and shrugged.

"Actually, I am his brother." Jace stepped forward, "And the hotness you feel from the room? That might be coming from me."

"It feels cold now." Simon glared at the blonde.

"Maybe we should ask Clary." Something clicked in Jace's gold eyes, as if he was realizing something, Simon caught his breath. "The heat could be coming from her hair."

I glared at the beautiful blonde strange man.

Jace shrugged at me, "You never know, you think it's just red hair but then it turns into fire. Lights the whole room."

My glare hardened.

"Clary, you need to pay Raphael a visit." Magnus ignored both of them to tell me, "He's been naughty."

"Not feeding under the scene anymore." Isabelle whispered. I nodded, grabbing my stele and starting to draw runes on my skin.

"Can I come?" Jace rose his hand, looking over at Simon in an 'I win' sort of way.

"Me too." Simon said quickly, the three of us looked at the two, shocked, "After all, I am a vampire. I think I would be more helpful than a mundane." He spit the word at Jace.

"I'm not a mundane. I'm a shadowhunter." Jace said stubbornly.

"With no training." I drew the precision rune on my arm, "You're about as much help as a mundane."

"Ha-ha." Simon said childishly.

"Don't get so arrogant." I told Simon without looking at either of them, "You would be no help either." I finished the rune and looked up at both of them, "However, Jace, I think that this would be good for you to go on. I think you should see how we do in fights."

"Yes, Clary," Jace said to me, but was obviously gloating to Simon, "I would love to join you on this mission. Start inking me." He walked toward me and held out an arm.

"Not so fast," I stopped him, "I think that Simon should come to."

"What?" Jace glared at me.

I shrugged, "He is a vampire. I think they would listen to him more than they would listen to either of us."

"Clary, how could you even begin to even consider brining either of them?" Magnus yelled at me.

I rolled my eyes without looking in Magnus's direction, "It's good training. The best way to learn how to swim is to be thrown into a pool."

"That also makes people drown." Magnus pointed out.

I smiled, turning around to face him, "Well, then it's a good thing Raphael doesn't have a pool."

Magnus fought a smile. "Either way, you have to come to my party tomorrow."

My smile faded, "That's tomorrow?"

"Yes, that's tomorrow night." Magnus smiled wider.

"What's tomorrow?" Alec asked.

"Magnus's cat's birthday!" Isabelle yelled in excitement. "I have to go get ready!" She ran out of the room.

"You have a birthday party for your cat?" Simon's eyes widened.

"Yes!" Magnus snapped his fingers and a second later everyone held a invitation, "And you are all invited! No themes!" He started to walk from the room, "Just don't look like a mundane." He eyed the three men, who all turned to look at me.

"I thought we were going to kill some vampires." Jace pouted.

"Do we have to go?" Alec half-whined.

"I would be doing the killing, actually." I told Jace and then shrugged, "Why not? A party can help us calm down a little."

"What are we supposed to wear?"

"You could go look in Magnus's closet," I shivered and started to walk from the kitchen, "But you might never come out."

"I think we would come out." Jace said darkly, following me, "Magnus has certainly come out of the closet." I heard the other two men leave the kitchen behind Jace.

Soon, the four of us were outside my bedroom and I opened the door to it. The three men behind me, stepped forward and I turned around sharply.

"Where are you three going?" I asked, feeling oddly self-conscious about my messy arts-and-crafts filled room.

"Is this not Magnus's room?" Simon asked, confusion in his brown eyes.

"This is my room. And, uh," I looked over the three of them and their height, "Call me crazy, but I don't think you will fit into any of my clothes."

Jace shrugged, "As great as I think I would look in a dress. I would much rather see you in one."

That statement caused me to blush, a feeling that shocked me, "I'll go get ready, you three go find Magnus." I opened the room further and started to back into it, making sure to keep the light off so they couldn't see inside.

"Wait," Alec kept the door open, "Which room is his?"

"One might say I'm very lucky," Jace eyed me, "But finding one room in two hundred total, some assistants could be helpful."

I pointed a finger down the hallway, "Down this hallway, take two rights, and then it's the second door on the left. Trust me, you'll know it when you see it." And with that I shut the door, ignoring their grumbling complaints through the closed wood.

Eventually, though, they faded and I drew a locking rune on the door, just in case. After that, I dashed into my closet before finding the beautiful black dress that I had been dying to wear. Giving the dress a final look and planning out the outfit in my head, I changed and went to sleep.

When I woke, the clock beside my bed said that it was passed twelve. Groaning, I rolled out of bed, changed, and then walked out to the kitchen.

"Good morning, sunshine." Magnus said cheerfully. I noticed that everyone except Alec and Isabelle were in the room around the table. "Would you like a pancake? I made them fresh."

"Did Isabelle help?" I asked, looking at the plate he was offering me. It looked normal.

"No, do you think I would be eating it if she did?" Magnus showed me a half eaten pancake on a plate I assumed was his.

"No, you aren't that crazy." I shrugged, "I don't want one, thanks. I think I'll make myself a sandwich." After making it, I walked over to the table and sat beside Jace.

"Good morning, Clary." Simon greeted me with a smile.

"Morning." I replied, taking a bite of my sandwich. I looked into Simon's eyes, they were darker than yesterday, much darker. "Have you eaten lately?"

Simon frowned, "No. I have been living off animal blood and I haven't gotten any for the last week."

"I guess I was wrong," Jace smirked, "I never thought you went to second base."

Simon glared at him, "I didn't mean it like that."

"Don't be ashamed." The blonde man winked at Simon.

"I don't want you to lose control, is all." I said to Simon. "With your hunger."

He shook his head, "I might be new to being a vampire, but I know when I'm about to lose control. And, I promise, I will leave if it happens. I wouldn't put you in danger, Clary." He smiled at me and I started to smile back.

"You smell nice." Jace muttered to me.

The vampire rolled his eyes and then turned to me. "When are we leaving for Magnus's party?"

"It starts at eight." Magnus said from behind us.

"So we'll be fashionably late." I nodded at Simon.

"Actually, you won't have to think about being late, what with how Isabelle acts." Magnus pointed out.

"Has she been working this whole time?" I turned around, astonished.

Magnus nodded, "Since three o'clock in the morning."

"She better be getting a face lift in that amount of time," Jace looked shocked, "It's been over nine hours."

"Hopefully she slept." Magnus said.

"Don't you think that is a little excessive?" Simon asked, "For her to work on herself that long."

I rose my eyebrows and turned to look at Simon, "You obviously don't know Isabelle Lightwood."

"Get to know her better." Jace glared at Simon. I rolled my eyes at both of them.

"I have to start getting ready, too." I told them, smiling as I left the room. I could help but notice how Jace's gold eyes and Simon's dark eyes followed me out of the room.
