Hey guys, after reading the last book City of Heavenly Fire written by Cassandra Clare – all credit goes to her – I thought I'd change things a little bit. Such as Alec's father becoming an Endarkened. I thought it would be an interesting plot so please read and tell me your opinions in the REVEIWS.

Change

"You guys stay together, I'm going on ahead to look for Jocelyn." Luke said before splitting directions with them.

"Right." Isabelle said and continued forward, Simon follow behind her when suddenly, she halted to a stop. Simon almost bumped into her.

"What, what is it?" She looked behind her, back to where Magnus and Alec were.

"Something's wrong." She said, though her voice was hesitant.

"What are you talking about? We have to find Jace and Clary." She bit her lip. Simon was right but something seemed… wrong.

"You go on ahead. I'm going back." And before Simon could protest, she dashed back where they had come from.

Alec had Magnus' arm propped over his shoulder and the warlock was leaning against him heavily and stumbling along the way.

"Someone's coming this way." Magnus said. Endarkened, Alec assumed. He stopped to listen and realized it was coming towards them, fast. Alec set his jaw and wondered how he would defend the both them. Magnus pulled away and Alec unstrapped his bow from his shoulder and locked an arrow into place. "Alec wait-" Magnus started but then Alec knew, the footsteps were lighter. Just then, Isabelle appeared breathless. She looked worried and confused. Alec dropped the bow and sighed.

"Isabelle, what are you doing here?" He demanded walking towards her. She looked between Alec and Magnus and shook her head.

"I-I thought something was wrong but…" She trailed off.

"Where are the others?" He asked, placing his hands on her shoulders. She looked up at him with distant eyes.

"We split. Luke went to find Jocelyn and I told Simon to go ahead." Alec felt uneasy. Isabelle had never looked so agitated and panicked in her life.

"Izzy, what's wrong?" He asked narrowing his eyes. She shook her head again.

"It's nothing. I thought… I had this feeling… Well it doesn't matter. It may just be the nerves of being here." She said. Alec wasn't convinced, however, there wasn't any time to ask what she meant. Alec turned towards Magnus and began walking towards him.

"Alright, we need to keep mov-" Before Alec could finish, there came a flash of light and before any of them could register what it was, a dagger lodged into Alec's shoulder, sending him back with a startled cry and his weapon flew out of hand.

"Alec!" Isabelle started towards him but he raised his other hand to stop her.

"No! Stay with Magnus!" He ordered. She looked torn but ran to Magnus anyway and drew out a sword. Alec reached for the hilt of the dagger from his shoulder, bit his lip and ripped it out. He was more frustrated than pained that he was caught off guard and he tossed the dagger aside. There came footsteps coming towards them from the opposite direction. Alec forced himself to his feet, his right hand pressed over his left shoulder, and he moved to stand between the Endarkened and Isabelle and Magnus. He drew out a sword from his belt and raised it with his left hand in anticipation.

"Alec, Alec, Alec." Came a deep familiar voice. A figure materialized from the shadows and Alec's sword slipping from his hand and clattered to the floor. He heard Isabelle gasp and Magnus take in a sharp breath. It was Robert Lightwood. He was dressed in the red gear. And he was Endarkened.

"Dad," He breathed in disbelief. Suddenly, his body became numb and he felt defenseless and hopeless.

"How- when did this happen?" Alec asked. His voice sounded distant in his own ears.

"Does it matter? I'm better now Alexander. I was blinded by the Clave's ways but now I understand they were wrong." His father said in disgust.

"No you don't. This is Sebastian's doing. You don't know what you're doing." Isabelle spoke for the first time. Alec chanced a glance behind his shoulder. Magnus looked devastated and tired and Isabelle looked like she was fighting to keep a steady face though he could see tears forming at the corners of her eyes. Alec turned back when his father spoke.

"Sebastian has shown us power. Powers we Nephilim have been forced to suppress."

"What are you talking about?" Isabelle cried. Robert's face twisted into a sicken grin. In a blink of an eye, he attacked Alec, throwing him against the wall. Alec's head made impact against the wall with a sickening crack and he slumped to the ground. Isabelle's scream was like a fading noise, droning in and out in his ears. Alec barley had enough time to crawl onto his hands and knees when he was lifted up by the collar of his gear and forced against the wall.

"You see, we are stronger, we are more powerful than you can imagine." His father said his eyes soaked in the new power.

"I thought you'd at least have had the honor to die instead of becoming this!" Alec hissed through his teeth.

"I am wake Alexander, more so than you can imagine! You can still join me."

"I'll never join you." Alec said trying to pry his father's hands off.

"Join me and I'll be proud of you." Robert grinned and Alec froze. "Isn't that what you wanted, for me to be proud of you? I will be, if you Change." Why? Why did his father's approval mean so much to Alec? Why did he want his father to be proud of him so bad, even to the point of changing? Maybe it wouldn't be so bad. He wouldn't have to worry about hiding behind Jace's shadow and he could be his own self. He could-

"Alec! Don't listen to him!" Magnus called, speaking for the first time. It snapped Alec back to reality and he acted swiftly. He brought his knee up, jabbing it into Robert's abdomen however he seemed unaffected. But he flinched and Alec took the opportunity to elbow his father in the jaw. Alec managed to get a few feet away before Robert grabbed for his injured arm and yanked him backwards. Alec fell to the ground; fortunately, he landed beside his sword and he picked it up and rose to his feet.

"Of all the boys that had to be born and it had to be someone like you." His father spat, reaching for the sword at his belt. He unsheathed it and held it out in front of him expertly. "You are nothing but a disgrace to the family." He swung to sword forward and Alec blocked it with his. The Shadowhunter did his best to drown out his father's words. He knew he was just trying to distract him, and knew it didn't mean anything but it hurt. Worse than the dagger to his shoulder.

"I killed your mother, you know that?" He grinned. At this Alec hesitated and Robert spun and kicked his son in the chest sending him stumbling backwards. Alec attacked again but it was weak and unstable giving Robert the upper hand to disarm Alec and send the sword flying. "I told her to join me but she refused, like you. So I killed her, slowly, painfully." He said in jest. Alec growling and attempted to throw himself at his father but Robert merely swatted him aside as if he were a bug. "With her last breath, she begged me not to kill you or Isabelle." He chuckled. "She was a fool." Robert stood over his son and raised his sword high, the tip of the blade facing downward. It seemed as if he were done playing around and he was ready to kill. He was about to bring the sword down when suddenly, something gold flashed and the sword went flying out of his hand. Robert cried out and cradled his hand where the whip had struck and tore the flesh. He glowered behind him. Isabelle was standing a few feet away, the edge of her whip coiled on the floor.

"You," He seethed and started for her.

"No!" Alec cried but Robert turned and slammed his boot on Alec's face with a crack, knocking him out cold and Isabelle winced.

"You insolent little bitch." He spat coming towards her. Fear and anxiety churned in Isabelle's stomach and she couldn't help but what came out of her mouth.

"Please, stop dad!" She knew he was gone, that it wasn't him. He would never change back but she was frightened and she didn't want to hurt him. Robert only moved faster, and picked up a fallen sword from the ground. Before Isabelle could react, Magnus jumped in front of her. Robert made a face of disgust and kicked the warlock aside. Magnus made impact against the wall and fell to the ground.

"Magnus!" Isabelle cried.

"I bet you've been wanting to do that for a while now." Magnus said trying to divert his attention. He sounded breathless and his voice was cracked as if he'd been running for miles. Robert sneered and advanced towards him.

"Filthy warlock, you will be the first to die." He hissed, pointed the sword at the warlock's throat. Just then, an arrow came sailing through the air and sank into Robert's chest with a thud. He staggered back with a cry and looked down in disbelief and then looked up. Alec was on his back, his bow in his hand. There was blood running down the side of his ear where his father had kicked him. His eyes were fixed and expressionless and he was breathing hard.

Robert dropped to his knees then fell backward but Isabelle caught him, bracing his fall. Her hands hovered over the wound as if she were afraid to touch him. Magnus ran to Alec and helped him sit up. He took the weapon away from his hand and tossed it aside. He then proceeded to tear the hem of his shirt and pressed it over Alec's wounded shoulder, trying to stop the bleeding.

"Izzy," Alec spoke, his voice uneven. "Izzy, I'm sorry. I had to, I'm sorry, I'm sorry." He said over and over.

"N-no, no." She said under her breath. "You killed him." She said in bewilderment. Suddenly, Simon appeared in the corridor.

"Isabelle, are you alright?" He started then swallowed when he saw the figure on the ground. "Oh God, is that-"

"Get her out of here!" Magnus ordered pointing in the direction he came from. Simon's eyes fell on Alec who was leaning against Magnus for support, to Robert's body, then back to Isabelle, and he began to put the pieces together. "Now Simon!" Magnus said again and the vampire seemed to snap out of it. He pulled Isabelle by the shoulder but she yanked away.

"No! Leave me alone!" Simon gripped her upper arm and haled her to her feet. "No! Simon, let me go!" she screamed reaching for her father but Simon was much stronger than she. "Dad!" She screamed and Simon wrapped his arms around her waist and carried her away.

Alec hadn't said a word after that, but he stared wide eye after his sister. He couldn't help but punish himself. He took away her father- their father, by his own hands. He wanted to run after her, hold her and apologize and try to tell her he didn't mean to kill their father. He tried to get up but searing pain shot through his shoulder and he slumped back down.

"Alec, stop you're hurt." Magnus said. The Shadowhunter turned his head and buried his head in Magnus's chest and took several deep breaths. For some reason, Jace's voice rang in his ear.

You're not me, you can breakdown. Alec had responded he couldn't. He had to keep it together, for the sake of finding Magnus. But now, he'd found Magnus and he was with him. So, did that mean it was okay to breakdown? He thought he was going to. He could feel a sob rise from the back of his throat and his eyes stung. He wanted to scream and cry towards the sky but it never came. He just felt… empty. The pain on his shoulder began to dull and so did the rest of his body. Alec moved Magnus's hand away and rose to his feet almost robotically.

"Alec," The warlock said quietly following him, as if speaking in a loud voice would shatter him.

"W-We have to go. Isabelle-" He choked. "Jace, and the others, we have to find them." He said taking a step forward but Magnus caught his wrist.

"Alec stop, you're not okay." Magnus said solemnly.

"Why does everybody think I'm weak? You all expect me to breakdown every time something happens to me. But I can't, I can't do that right now." Alec said darkly. Magnus's cat eyes were sad, as if he'd seen this kind of reaction before and there was nothing he could do about it.

"Alec, I know you, and this isn't you." He said.

"Maybe you don't know me as well as you think." He snapped turning on his heel. His eyes fell on the figure on the floor and saw his father, eyes wide open and an arrow in his chest. Alec knelt down beside his father and gently closed his eyes, so that he could at least pretend his father was sleeping. Alec suddenly felt sick and he staggered back. Magnus caught him and Alec chocked back another sob. "We have to find the others." He said again pushing Magnus away.

If you guys liked this, I did write a few more sections and little scenes clipped from the book. If you're interested, let me know because the next one is about Alec and Magnus staying behind after Asmodeus sends everyone back to their natural world.
