Chapter 3

A day later, after Jace had been cleared to leave the infirmary Clary and Isabelle met Isabelle's mother Maryse by chance in the entrance to the Institute and she was not happy that the Fairchild girl was there. She stormed past both girls and to the training room where Jace was practising with a seraph blade. Alec and Agatha arrived in the training room shortly after her. Once Maryse gave the children their missions Agatha followed behind Isabelle and Jace – who went their separate ways while Agatha continued behind Maryse.

"Aunt Maryse," Agatha stood in the door way to the study which held Maryse sitting behind her desk looking over paperwork.

"Agatha, so you weren't lying when you said that you would be coming back to the institute," Maryse was quite abrupt with the young woman as she spoke. "Come in and close the door behind you,"

"You can be angry at me all you want, and I may be part down-worlder but I'm also a Shadowhunter, a nephilim," Agatha paused as she spoke looking at the older woman. "I've always looked out for Alec, Izzy and Jace and I always will,"

"We keep our relations separate for a reason Agatha,"

"Enough Aunt Maryse, you're the one that gave me permission to do everything that I had to do. So please stop hating on me," Agatha was getting frustrated with Maryse blaming things on the downworlders when it wasn't their fault.

Agatha and Maryse talked quietly, Maryse making it a point that she wasn't too happy that Agatha was back. After a while it became apparent that one of the reasons that Agatha had turned up when she had was because Jace and her wild dreams. Maryse put Alec and Agatha in charge of guarding Clary, neither Agatha or Alec particularly wanted to do it.

Hours later and Clary snuck out of the institute and went back to her old loft where she subsequently was kidnapped by werewolves. Jace was definitely not happy with his sister or Alec for letting her get taken. Neither of them could help that as they had both heard something outside of the loft and gone to investigate which was when Alaric had taken them.

"Jace stop yelling at Alec, it's not our fault. You yell at him one more time and I will put you on the ground," Agatha hissed at her brother taking Alec by the arm. "Alec come with me, and Jace calm your ass down," Jace and Alec had tried parabatai tracking Clary to no avail.

"Aggie, it is our fault..."Alec started to say but was silenced by Agatha.

"Alec, it's not. Not even I could foresee what was going to happen with Clary," Agatha told him, as she attempted to calm him down. "Look at me. Jace is your parabatai and he doesn't blame you, he may act like he does but you know that he trusts you with his life,"

"Aggie, those are just words," Alec muttered looking down at her even though deep down he hoped what she was saying was true.

While Agatha and Alec had talked Simon had managed to call Clary's phone which happened to be in backpack which had been left at the loft but Isabelle had grabbed when Jace had stormed out. Jace scrambled of Clary's phone answering it on speaker while Agatha quietly told Alec that she had to see Magnus about something and that she'd meet up with them later. Alec, Isabelle and Jace ran off to save Clary and in the process Luke found Clary before they did and in doing so fought the alpha werewolf winning.

"We need to take him to warlock, only a warlock can heal a werewolves wounds," Jace told Clary and Simon while Alec tried to get him to see reason and return with Clary to the institute. "You be the golden child and tell mother about this, but I'm staying with Clary,"

"Jace," was all Alec said as he watched Simon, Clary and Jace take Luke to his car.

"Are you too okay?" Isabelle questioned, looking up at her older brother as she spoke and then watching as the others drove off. "Where did Aggie go?"

"Magnus," Alec answered looking to his sister as he spoke and then staring after the car. Alec felt his phone vibrate in his pocket and glanced down at it as he spoke pulling it out to answer. "Hello?"

'Alexander,' Magnus said on the other end, Agatha was standing their prompting him to call again as she knew that Alec had hung up on him before.

"I don't have time for this, sorry," Alec was about to hang up the phone when Agatha snatched Magnus' phone from his hands.

'Alec, just listen to him. Go for a drink with him...I know you want that, and it doesn't have to be tonight just promise me that you will,' Agatha said with a smile as she looked at Magnus who raised his eyebrow at her as there was a knock on his door. 'Alec, where's Jace and Clary?'

"On their way to Magnus," Alec told her, Isabelle looked at him curiously wondering who her brother was talking to.

"Luke!" Agatha suddenly exclaimed, when she realised that the down-worlder and her uncle was outside of the lair. 'Alec, you and Isabelle are coming here now I'm opening a portal,' Agatha told him, not waiting for him to start protesting.

"How did you..." Alec questioned, as the portal opened up in the door of one of the containers in the dockyard.

'He's my uncle Alec, now get your ass here and Isabelle's too,' Agatha said abruptly hanging up her phone as Magnus let Jace, Clary and Simon into the apartment with Luke.

Alec stared at his phone pocketing it before telling Isabelle that Agatha wanted them to go through the portal to her. He didn't often disagree with her, and he knew that his mother would not be impressed with any of her children. Isabelle didn't care about that she just wanted to know that Agatha was okay.

"What happened to him Jace?" Agatha questioned, as Magnus' apartment shook with Isabelle and Alec arriving. With a wave of her hand the portal closed behind them. "I'm waiting Jace,"

"Why are you questioning him?" Clary asked, looking at Agatha as Jace and Simon put Luke onto the couch that Magnus had directed them too.

"He fought the alpha of the werewolves, did you know?" Jace replied in question as he walked back over to her and stood in front of her. Alec was standing slightly behind the older girl.

"Did I know that my uncle was a werewolf? Yes, Jace I knew that. He's just one reason why Maryse is the way that she is," Agatha said glancing behind her as she spoke. "Alec..." she trailed off grabbing his hand and refusing to let go. "Magnus, can you help him?" she questioned still holding on to Alec's hand and pulling him with her as she walked over to Magnus.

"You know that you can help him," Magnus told her as he started to heal him, Agatha shook her head. "Aggie, you can. I know that,"

"No," Agatha refused, she looked at Luke and then at Magnus. "I can't..." Agatha trailed off this time it was Alec's turn.

"Aggie, why? Why can't you?" Alec questioned, forcing the older girl to face him.

"Because I just can't. Leave it at that," Agatha muttered glancing at him and trying not to show that she was actually scared.

"Come with me," Alec dragged her away and to the window, Isabelle moved to follow but Alec shook his head and motioned for her to stay with the others. "You're scared, you don't think you can do it do you?" he asked quietly so the others couldn't hear what he was saying to her.

"No..." her voice shaking as she spoke.

"Aggie," Alec sighed pulling her close and then looking over and Isabelle who was staring at them. The others too focused on how Luke was doing. "What was it you told me earlier? Don't be scared?"

"Alec, when emotions are involved my magic is unstable you know that," Agatha hissed, she wasn't perfect none of them were. "If I try, it could kill him not save him...and Magnus can save him,"
