The institute shook as Izzy slammed opened the door and stormed inside, her fellow shadowhunters jumping out of her path, scared to meet their fate at the hands of an angry Isabelle Lightwood. Izzy didn't bother knocking on her mother's office door instead she threw it open and stormed inside, Maryse looked up, raising an eyebrow at her daughter who slammed the office door shut.

"You told me my older brother was dead" Izzy stared as she glared at her mother.

"Alexander has told you," was all mother said.

"Eventually after Valentine kidnapped him, tortured barely escaping only to lose control of his magic," Izzy said, "Not that you care because you threw your own child away like they were trash,".

"Isabelle, you don't know my reasons for giving your brother up, when you have your own children, you'll understand, but until that day comes you don't have the right to question me on my past decisions. I still stand by what I did that day, Alec is in better hands with Jocelyn," Maryse said as she turned back to her paperwork.

"He's my brother! My apparent dead brother! What would Dad or Max say if they knew what you did?" Izzy challenged.

"Your father was in on the decision to give Alexander up and Max is too young to understand," Maryse said, and Izzy felt something inside her snap.

"I see because we didn't turn out like those perfect law-abiding children you oh so craved. Our opinions don't matter, we don't matter. I'm surprised you didn't throw Max and I to the mundanes when we disappointed you or didn't you find the chance," she said opening the door and leaving the office, ignoring her mother's shouts for her to come back.


"Where are we going, Alec? You can't just suddenly demand me to come with you and not tell me where!" Clary whined as she tried to keep up with her brother's long legs, "And shouldn't you be resting back at Magnus' after losing control of your magic".

"Why do you think we're walking, I'm trying to limit my magic usage until I'm happy that I'm not going to lose control again," Alec said, "And if I tell you where we're going then you won't come with me,".

"Alec, I would go to the end of the earth with you," Clary said, and Alec suddenly stopped moving which nearly made Clary run into the back of him.

"We're going to Luke's," Alec said.

"What! Why! He hates us, Alec, you heard what he said at the precinct," Clary argued but Alec shook his head.

"I know but we need answers to what happened and until we find a way to wake Mom up, then we have no choice but to go to Luke," Alec said, Magnus had tried everything he could to wake Jocelyn up, but it was no good. They would have to find the warlock who made the potion first and ask them to reverse it.

"Are you sure we can trust him?" Clary asked, and Alec shook his head. Unless Luke gave them a reason to, then Alec hadn't planned on trusting Luke.

"We can't trust Luke, so if it comes to it, I can use my magic to influence Luke to talk with us. Hell, he might believe that we don't know that we overheard him that day and would willingly give us the information we need," Alec said, and Clary sighed.

"Okay, you have point just try not to overuse your magic," Clary said. The rest of the walk to Luke's was quiet. Neither sibling knew what they could expect when they arrived. The only positive was that Luke's truck was outside his house when they reached it. Alec knocked on the door and he heard the clattering on noise as Luke stumbled through his house before opening the front door.

"Clary! Alec! Thank god you're okay, where have you been?" Luke said relieved as he moved out the way and let Clary and Alec into his house, stepping into the lounge after closing the door. Luke sat on the sofa beside Clary whilst Alec sat in the armchair opposite.

"We know about the Shadowworld. Clary knows she's a shadowhunter and I'm a part warlock, part-shadowhunter. Valentine took our mother and after he captured us ourselves, we escaped and rescue our mother," Alec explained, they need to be honest with Luke, tell him a little of what they know so it forces him to tell them the rest.

"Thank the angel, I kept tell Jocelyn that she needed to tell you the truth, but she always refused, she didn't want to include you in the shadowworld. She had plans to tell you after Clary's 18th but couldn't after everything that happened," Luke said, "Where have you been staying?".

"It doesn't matter, Luke we need honest answers about our mother, she's still unconscious," Clary said.

"Of course, what do you already know?" Luke asked as Alec and Clary shared a look. This was going well so far.

"Luke, we know about the uprising and the part our mother had to play. We know that Valentine is Clary's father and that he despises Downworlders, and that he… made me the way I am. What I don't understand is why you and mom kept this from us," Alec explained.

"Because we were afraid that you would hate us, and it became easier to keep it a secret," Luke sighed, "But you still don't know everything. What you need to know will help you find the Mortal Cup,".

"How?" Clary said, confused, and Alec frowned.

"You're just gonna have to trust me," Luke said, and Alec couldn't help himself but scoff when he heard that.

"Debatable after what we overheard at the police station. You said you hated us, and the only reason you're sticking around was so you could find the mortal cup," Alec said. He knows he really shouldn't be bringing that up, but he couldn't help himself. Luke had been like a father to them.

"I was lying, Alec, Clary, you mean everything to me but if the circle believed that they could find you by tailing me then you would've never been safe," Luke said, "I promise I'll explain everything,".

"Talk" was all Alec could say, he wasn't sure what to believe.

"But first you need to understand my situation with the shadowworld. Originally I was a shadowhunter, but now I'm a werewolf," Luke said, and all he received were blank faces.

"We know, Simon told us" Clary shrugged her soldiers, after everything had calmed down and they returned to Magnus' without Izzy, Magnus had told them the whole truth about the uprising and then Simon told them that Luke was a werewolf, the alpha of the New York pack.

"What? Oh, Simon finally told you he's a vampire" Luke said sighing, he had hoped he could have been the ones to tell Clary and Alec but then again he shouldn't be surprised, Simon could barely keep any secrets from his friends, "Well, with that in the open. You know about the uprising?".

"Yeah" Clary nodded.

"About the Valentine who murdered all those people?" Luke added.

"Yes," Alec said unsure with where Luke was going with this.

"The reason he became that man was our fault… mine and Jocelyn's. We betrayed him, Clary… your mother and me. We fell in love. When I was a shadowhunter, Valentine was my parabatai and as time slowly went by Valentine became more violent towards the clave and we tried to help him, but he kept pulling away from us which resulted in us getting close and when he discovered how close Jocelyn and I were, he believed we were having an affair," Luke started explained.

"Valentine became desperate to win Jocelyn's heart back, but that led him to compromise his own principles and he started an experiment with Downworlder blood and not just on himself, on the unborn children of circle members. Most of those children died but one… you Alec," Luke said, so, his mother and Luke knew all this time about his situation and they never thought it would be wise to explain this to him, "Maryse came to Jocelyn begging her to take you with her because she was scared what Valentine or the calve would do if they discovered that you were half-shadowhunter half-downworlder,".

"Our love drove him to commit these monstrous acts," Luke added.

"What was he like back then? Before he, you know…" Clary asked. She was curious about how her mother could fall in love with a man like Valentine.

"In the early days of the Circle?" Luke said and Clary nodded, "Oh… he was honourable, idealistic. He was charismatic, he was a leader devoted to protecting us from dying pointless deaths,".

"And you believed in him?" Alec said.

"If Simon told you he had the cure for cancer, you'd wanna believe him, too," Luke challenged.

"Well, I'd probably give him the benefit of the doubt at least," Clary said, smiling.

"Which is what I did. The demons were winning, and we couldn't train our people fast enough to keep up. Val wanted the Clave to use the Mortal Cup to create more Shadowhunters, but that just made them angry," Luke explained.

"Isn't more Shadowhunters a good thing?" Alec said, which in fact was debatable enough because he knew plenty of warlocks who would disagree with that notion.

"Not the way he was proposing. Ever since the Angel Raziel created the first Shadowhunters with the Cup, it's been forbidden to use the Cup again to rebuild their forces. Jocelyn and I, we tried pulling him back, but he just misconstrued that as…" Luke said before trailing off.

"The affair. It's not your fault, Luke. There's no way you two could have pushed him over the edge. He did that to himself… with the blood injections," Clary continued before letting out a loud sigh.

"And the more injections he took, the deeper it seemed he descended into madness," Luke continued.

"Then how am I fine if mixing angel and demon blood can turn a shadowhunter mad. I know I have my moments but still… I don't feel mad," Alec said. They were both shadowhunters first, so what made Alec's situation different.

"Because what happened to you was before you were even born, your body adapted whilst Val, his angelic blood fought back against the demonic and he went mad," Luke said before standing up and walking over to his sideboard pulling out a sketchbook that neither Alec nor Clary had seen before and handed it over to them, "It belongs to your mother, during the days of the circle she loved drawing but after a certain night she locked that part of herself away,".

Alec and Clary flicked through the sketchbook, it was filled with drawings of flowers, landscapes, a young Valentine and Luke.

"What did my father do?" Clary asked, looking at Luke worried when she reached the last sketch.

"Your mother is the only other person I ever told this to. I never wanted to burden you, either of you," Luke said, taking a deep breath.

"Tell us," Alec asked. They needed to know.

"Valentine asked me to back him up on a mission. Some farmers had gone missing. He said it was werewolves. When I entered the barn, Valentine locked the door behind me, and werewolves attacked me. He betrayed our parabatai bond and then he betrayed everything else he believed in," Luke said as he ran a hand over his face, "During the uprising, I fought with Valentine and when I thought he was about to kill me, Jocelyn saved me, she fought against Valentine, grabbed the cup and ran off with Valentine chasing after her,".

"For a while, I thought he'd killed her. He wanted us both dead, he killed thousands. Turned Shadowhunter against Shadowhunter. Do you understand what I'm saying?" Luke said.

"God only knows what he'd do if he got the cup" Clary added, and Alec didn't even want to think any further with that thought.

"The last we saw Valentine was during the fire, but we don't know whether he's dead. We need to find the cup regardless if he's alive or not," Alec said. If Valentine was still alive, then he might become even more desperate to find the mortal cup.

"But I don't know where it is. Or even where to look," Clary said, throwing her arms up in the air.

"It all starts and ends with you and Alec. I know Jocelyn and her children would be the only people she would have trusted with the location of the cup," Luke said.

"If she trusted us so much, why didn't she tell us any of this?" Alec retaliated with; the whole evil man was after their family seemed quite important to keep a secret.

"She didn't think this was gonna happen. She made provisions, just in case it did. The potion, Dot, teaching Alec to use his powers… Jocelyn said that I should tell you everything about our past. That it would unlock you," Luke said, motioning to Clary on that last part.

"What does that even mean?" Clary said, feeling even more confused than she did coming here.

"I don't know! But you do. There are clues. They're inside the mundane world. Think, Clary" Luke said, Jocelyn never explained what she meant about unlocking Clary but had the time come then their past would somehow do that.

"I don't remember anything. If Mom hid the clues, I don't know what they are," Clary sighed.

"You have to figure this out!" Luke said.

"Then tell us about this" Alec said using his magic to summon a small box with the letters JC on it.

"What's that?" Clary said, confused. She had never seen that box before in her life.

"Mom was always terrible at hiding stuff from me, I don't know why, but I could always tell what objects she had a significant emotional attachment to. Probably something to do with my magic, so one day I found this under the floorboards in Clary's room. I asked mom about it and she said it belongs to Clary's 'father' and got me to promise to never show Clary it or look inside. However, I did once and… you'd better see for yourself,' Alec said handing the box over to Clary, he had never thought that this box would mean anything, hell, he had briefly forgotten about it but just then when Luke was talking about Valentine, it made little sense to what their mother had said. Jocelyn would cry over this box yearly, but why would she cry over something that Valentine owned.

Clary frowned as she opened the box and gasped as she pulled out a baby's shoe and a lock of hair, "What is this?".

"No, I want you to remember your father could be a good man," Luke said, his heart dropped when he saw the contents.

"After what he did to you-" Clary said, putting the shoe and hair back in the box and placed in on top of the sketchbook before looking back at Luke.

"This is worse, Clary," Luke said shaking his head.

"I don't care! Luke, I want to know, I… we need to know. You said so yourself. You have to tell me everything," Clary begged, and Luke sighed.

"JC stands for Jonathan Christopher… your biological brother," Luke said, and Clary gasped.

"I… I have a brother?" Clary said, yes, she had Alec and no matter whether he was adoptive, he will always be her brother but… to have a biological brother that had been kept away from her.

"You did. He died in a fire at Fairchild Manor, a fire that your father set" Luke said. Alec wanted to hug his sister as she silently weeps for her lost brother, putting her hand on the box which contained his belonging only for it to vanish into the pages of the sketchbook. Alec's eyes widened as he moved closer to find that the box looked like a drawing. Alec and Clary shared a look, both feeling bewildered with what had happened.

"That's it. That's the ending of the story that our mother needed me to hear, but… if that what she meant to unlock," Clary said pointing at the drawing, "How did I do that?".

"There are Shadowhunters that have unusual Angelic Powers, but I've never seen anyone do what you just did," Luke said.

"I have. Clary, do you remember when we were seven, you lost your favourite doll that you slept with that drawing of it until Mom got you a new one. What if what just happened now happened back then?" Alec said, and Clary's eyes widened as she looked back over at Luke.

"Can these powers be inherited?" She asked.

"I think so" Luke replied.

Clary grinned look back at her brother, "I know where mom hid the cup".
