Chapter 2: The Cure

"We have been looking for hours." Jace said as the group entered the apartment.

"Well, we are not going to stop," Clary told him.

"Of course not but we need a new approach," Alec replied.

"I agree," Jordan said.

"Make the call," Jace told Alec.

"No," Alec said.

"What call?" Clary asked.

"Make. The. Call." Jace said and emphasized every word.

"I. Cant." Alec said using the same tone.

"What call?" Clary demanded.

"Magnus can do a locator spell," Jace said.

"Make the call," Isabelle told Alec.

Alec slammed his fist into Jordan's wall and dented the plaster, "I SAID NO!" he shouted.

"Dude!" Jordan complained and threw his hands in the air. "There goes my security deposit."

"We can fix it," Maia assured her boyfriend.

"Alec," Isabelle started. "Please?"

Alec balled up his fists and looked at the floor. It felt like hours before he spoke,"Ok, I will go and see him. But if he blows me up and feeds me to Chairman Meow...it's on all of you."

Jace smirked in response.

Alec walked out the door silently.

"You think Magnus will help?" Isabelle asked Jace.

"Of course," Clary said. "He doesn't have anything against Simon."

Jace and Isabelle knew it wouldn't be that easy.

Alec paced outside of his ex's apartment for five minute before he had enough courage to ring the bell. It seemed like forever before Magnus answered the door. Alec felt his heart drop when he saw Magnus. he looked great.

Magnus was wearing a tight fitting black shirt and tight black jeans. He had a rainbow colored belt around his slim waist. His hair was a mess. He looked tired ...like he wasn't sleeping. That made Alec strangely happy. Maybe Magnus missed him too?

"What do you want Alexander?" Magnus asked, exhaustion coloring his tone.

"I ...we...I..Isabelle needs your help," Alec finally found the words.

"Is she ok?" Magnus asked.

"Yeah, she is fine," Alec told him.

"Alec...I told you not to come here. I told you I was done helping shadowhunters." Magnus replied.

"I know," Alec told him. "I told them that I wouldn't come here but..."

"But what?" Magnus asked.

"But Isabelle had the same look in her eye that she did when we were kids and she was scared of thunder and needed me to comfort her. I couldn't let her down." Alec explained.

Magnus was quiet for a moment and then he stepped back, "Come inside. We will talk. I am not making any promises."

Alec tried to smile but it didnt really work. He was sure it looked more like a grimace. He followed Magnus inside. It was eeirlly familiar. But it felt like a dream. Like it was a part of another life.

Magnus closed the door behind Alec once they were inside. Alec noticed a young woman sitting on Magnus's couch. She was pretty. She had dark hair pulled into a loose, messy bun on the top of her head. She was wearing a blue button up shirt and dark blue jeans. She was barefoot like Magnus. She put her teacup down and smiled at Alec.

"This is Tessa Gray," Magnus introduced the woman.

"You must be Alec?" she said. She stood and shook his hand. "It is so nice to finally meet you."

Alec was confused. Who was this woman? A new lover? A friend? She appeared human but there was something timeless about her. It was the same quality Magnus had. Was she a warlock? He didnt see a mark?

"Nice to meet you," Alec said gruffly. He used the same voice he used in Clave meetings-professional and disconnected. "We need to discuss something so...?"

Tessa started to leave but Magnus stopped her.

"This is business. She can stay." Magnus said.

Alec looked down. That stung a little. "I don't have any money on me," Alec admitted. "But I am sure my parents or..."

"We can discuss that later," Magnus interrupted. "What is going on?"

"Simon is missing," Alec told him.

"The daylighter?" Tessa asked.

Alec nodded.

"How long?" Magnus asked.

"About 6 hours," Alec answered.

Magnus rolled his eyes,"That is why you are here?" he said. "6 hours? That's nothing. Maybe he went to talk to his mom or...?"

"Clary's mom checked on that. No, his sister and mother haven't seen him." Alec took Simon's cell phone out of his pocket. "We found this on the street. It was covered in blood. There were some signs of struggle...trash cans turned over. Some blood further down the street."

Magnus exhaled loudly, "Well, that is a horse of a different color," he said. "Do you think Simon hurt someone?"

"Any other Vampire, I would say maybe, but not Simon," Alec said. "He is pretty controlled."

"We all go a little mad sometimes," Magnus grinned.

Alec felt a shiver up his spine when Magnus smiled like that. "Either way we have to find him."

"You want me to do a locator spell?" Magnus asked.

Alec nodded,"Will this work?"He took Simon's keys from his pocket.

Magnus looked unconvinced,"I don't know," Magnus admitted. "Might not be personal enough but I can try." He looked at Tessa, "Would you mind waiting with my guest?"

Tessa smiled,"Not at all," she said kindly.

Magnus walked out of the room. Tessa and Alec were silent. Finally Tessa said, "Sit. Let's get to know each other?"

Alec begrudgingly took a chair across from her. He didn't know what to say. He had no intention of befriending someone Magnus was sleeping with. He looked up and saw she was staring at him. She seemed lost in time.

She caught Alec's eye and looked away,"I am sorry," she said after taking a sip of her tea. "You look remarkably like someone I knew once."

He remembered Magnus saying something similar, "Will?" he asked.

Tessa nodded. Her expression was sad and so was her voice as she spoke,"Yes, Will Herondale. He was shadowhunter too."

"Will Herondale?" Alec questioned.

"Heard of him?" Tessa asked. "He was an amazingly talented young man."

"No, I mean not really...but that last name...That is kind of my brothers last name."

"Jace, yes, I know of him." Tessa replied. "Can I get you something?"

"No," Alec shook his head.

"Are you sure?" Tessa asked.

Alec nodded. The two sat in an awkward silence.

Tessa cleared her throat, "Magnus and I are friends," she told Alec. "Just really dear friends."

Alec realized she was trying to tell him that she and Magnus werent together. He felt relieved momentarily then he realized just because Tessa wasnt with Magnus didnt mean he didnt have someone.

"He isn't seeing anyone," Tessa said her voice barely above a whisper.

Alec froze, "You're sure?" he asked.

Tessa nodded. She leaned forward and patted Alec's hand,"It will take a long time for him to get over you. "

Alec ran a hand through his hair. Magnus wasnt seeing anyone. Maybe Magnus still loved him? Maybe they could have a second chance?

Magnus came back into the room. He was putting his shoes on,"I found him," he told Alec. He looked at Tessa, "You coming?" he asked as he grabbed his keys.

Tessa was already putting on her shoes,"Yes, if Alec doesn't mind?"

Alec smiled,"It's fine," he said.

"Let's go," Magnus said.

Alec wondered why Magnus didnt just tell him where to find Simon. He knew Magnus well and the distinct impression that Magnus was keeping something from him.

Isabelle felt numb as she watched Jordan and Alec carrying Simon into the apartment. They laid him on the couch and propped his head up.

"What is wrong with him?" Clary demanded.

Isabelle was sure it was 500th time Clary had asked that same thing and her voice got shriller each time she asked. It was giving Isabelle a headache. "Someone answer her," Isabelle ordered.

Magnus and his friend Tessa were looking all over Simon's body for something. Finally Tessa touched Magnus's arm. "I found it," she said.

"Found what?" Clary was practically shrieking at this point.

"Syringe mark," Magnus observed.

"Someone injected him with something?" Jace asked.

"Yeah," Magnus sighed.

"Like a drug?" Alec asked.

"Worse,"Tessa replied.

"How much worse?" Jace said.

"Lamia Mortalitas," Magnus answered him.

"That means what?" Maia asked.

"Vampire death," Alec replied.

"It's a disease," Magnus said."It was created by a Greater Demon. I havent seen a case of it since ...well, in 500 or 600 years."

"Vampires can get diseases?" Maia asked. "I thought Vampirism was a disease."

"It is," Magnus replied. "But a sick person can get sicker. Someone with Cancer can get Pneumonia."

"Well, if it is a disease then it must have a cure,"Clary said sounding tearful. "Do you know what the cure is?"

Magnus and Tessa exchanged a look and Magnus said gently, "I have never heard of one."

"No," Isabelle whispered. "There has to be. We have books at the Institute."

"This won't be in any of those books," Magnus told her.

"Zachariah," Tessa said softly.

Magnus nodded. He looked at Jace. "We need to talk to the Silent Brothers"
