So I started this because I've had this idea for a very long time! I'm not sure how long this story will be, but I'm very excited to be writing it, so let me know your thoughts on it!

Also, a side note that in this story, Camille was not killed, but the relationship problems that Magnus and Alec went through still apply!

One of the first people to ever make Alec feel as though he could commit murder was Camille. Every time she was anywhere near him, his stomach tightened enough to make him feel nauseous. She'd done everything she could think of to try to keep Magnus and Alec from staying together, she had tried everything possible to break them up. Some days, Alec still couldn't figure out exactly how he and Magnus had pulled through and ended up together, but he tried to keep from thinking of it too often. Alec had found that overthinking it was the worst thing he could do, so he just stayed grateful for the fact that they had pulled through.

But, of course, on the one night that he and Magnus had alone, on the one night they had decided to take for themselves, Camille had showed up and immediately began wrecking things. At first, Alec had thought that she was actually going to ignore them and leave them alone. Alec resisted a groan as she began walking toward their dinner table.

"That's cute, Magnus," she said as she got closer. Her voice sent chills down Alec's spine as he tensed up. Magnus seemed to sense this because he reached across their table to take hold of Alec's hand. Alec also realized that he was doing this to show Camille that she wasn't going to be able to break them apart, so Alec left his hand in Magnus's and simply looked anywhere but where Camille was. "Your darling boyfriend taking you out on a day like today. It's sweet. Trying to cheer you up, is he?"

Alec understood the words that were coming out of Camille's mouth, but he had no idea what she meant my them. He looked up at Magnus in confusion, and he could see the open pain written all over his face. The only problem was that Alec had no idea what Magnus was in pain over. But he didn't have any time to think about it before Magnus responded. "Go to hell, Camille," he said, his voice ice cold. "Or did they kick you out because you were too much for them to handle?"

The way Camille smiled back at Magnus made Alec want to smack it off of her face, but he forced himself to stay silent and remain seated until he figured out exactly what was going on. "I tried it out, and it didn't suit me," she threw back at him. "But you might be able to ask Lena how it is down there right about now." The more they said to each other, the more confused Alec became. Just as he squeezed Magnus's hand for what he thought was support, Magnus shot up from his seat.

"Never say anything like that again," he said, his voice more of a growl than anything else. It was easy to see that whoever Lena was that she had been extremely important to Magnus. The only thing that slightly confused further was that Magnus flicked his eyes nervously toward Alec as though he was afraid of Alec learning too much about what was going on. "If you value your life, you will walk away right this second," Magnus finished in a way that Alec had never heard him.

At that, Camille simply laughed and turned toward Alec. "You may think he's been completely honest with you since you got back together," she said, the smile on her face slowly becoming icier. "But I wouldn't count on that just yet, Alexander." With that, Camille turned away from them and went to her own table, but her words still lingered in the air.

There was nothing that Alec could think to say, so he simply watched as Magnus took his seat once more, his shoulders slumped in a way that tore at Alec's heart. When Magnus stated that he needed to go home, Alec didn't fight with him, he simply asked for their check. Alec never really thought about becoming angry. He knew that Magnus's past was so long that there was a lot he still didn't know; Alec had resigned himself to the fact that he would be learning new things about Magnus for the rest of his life. At the moment, the only thing he was concerned about was making sure that Magnus was alright.

The thing that began to make Alec angry was the fact that Magnus began to try to avoid the conversation. He'd immediately said that he didn't want to talk about it, which was what had begun their relationship problems the first time around. Sitting down on the couch beside of Magnus, Alec tried to keep his voice as gentle as possible. "Magnus, I understand that you're hurting, and I want to help you. But the only way I'll be able to help you is if you talk to me about this. I'm not going to bed tonight unless we talk about this. I'm sorry to be like this, Magnus, but we need to talk."

To Alec's surprise, Magnus didn't fight back, he just sighed and closed his eyes for a moment. "You're going to be angry, Alexander," he said, his voice so resigned that Alec wished he hadn't been so harsh. Before Alec could respond, Magnus continued, looking down at his feet. "I never told you this, Alec, because it's something that's so painful. I wasn't hiding it; I swear that to you. But every time I tried to tell you, I couldn't seem to get through it."

Instead of responding, Alec just reached over to take Magnus's hand, trying to keep calm until he knew what was going on. "Lena," Magnus said, his voice filled to the brim with emotion. "Alexander, Lena was my world. Lena was my everything. And now she's gone." For a moment, Alec thought that Magnus was talking about a love interest, but then Magnus finished his thought. "Lena was my daughter."

It took several moments for Alec to register what Magnus had just said. He felt like all the air had been sucked out of his lungs, and the only thing he could seem to do was squeeze Magnus's hand. "Magnus," Alec began, trying to find the right words.

"Don't." Magnus cut him off, his voice suddenly becoming much harder than it had been before. "Alec, don't. I don't think I could take you being angry with me right now. Just let me finish before you say anything." Alec remained silent despite himself. "Lena died at eight years old, Alec. She was murdered in cold blood. Alexander, my daughter was murdered by Shadowhunters because she was a warlock. It's been twenty years today since I lost her. That's what Camille was talking about."

When Magnus got up from the couch, Alec could see that he was just scared that Alec was going to be angry. The problem was that Alec was so far from being angry that he couldn't even imagine it. He got up and followed Magnus, knowing that he needed to take care of Magnus if that was at all possible.

The first thing Alec did when he caught up to Magnus was reach for his hand. "Magnus, wait, please. I'm not angry with you. Quite the opposite, really." Magnus stopped walking halfway to their bedroom, and Alec could see how surprised he was that Alec was saying anything of the sort. "You didn't tell me because you were hurt, I understand that, Magnus. It happened so recently. You're hurting, so let me try to help you in any way I can."

Alec had thought that this would have been a good thing to say, but Magnus apparently had other thoughts. "Help me? You think this could ever be fixed? You honestly think that you could ever help me through this?" At first, Alec wanted to run away from the conversation, but he made himself regroup and try to find any way to comfort Magnus.

"Magnus, I'm sorry. I know this can't be fixed. I never meant to imply that it could be." Without thinking about it, Alec reached up to push the hair out of Magnus's eyes. "Please just talk to me." Just as quickly as Magnus had become angry, he switched back to being open with Alec, and Alec had to remind himself that Magnus was brokenhearted at the moment.

"I want to show you something," he said, taking hold of Alec's hand and leading him back toward the bedroom. Once there, he motioned for Alec to sit on the bed while he walked over to a bookshelf and pulled out a photo album. When he came to sit beside of Alec, he reached to open the album with hands that were shaking slightly, and Alec couldn't find anything to do to help him.

He turned to a page and handed the album to Alec. "That's her," he said, his voice barely above a whisper. Alec looked down at the picture to see Magnus holding Lena. Lena had long black hair that had been done in braids. Her huge brown eyes were looking up at Magnus with such love that it almost pained Alec to look it. The smile on her face was large enough for Alec to see that she had loved her father with all her heart.

"Her warlock's mark was her ears," Magnus said, his eyes on the picture. "They were pointed, so she always wanted me to do her hair in braids so she could hide them easily." Magnus paused and took a deep breath. "She was always so happy, Alexander. Nothing ever got her down. She could make me smile no matter what was going on. And then she was taken from me."

This time, it was Alec's turn to take a deep breath. "She was beautiful, Magnus," was all that Alec had the courage to say. He wanted to say so many more things, he wanted to find the prefect thing to tell Magnus, but everything seemed to leave him all at once.

"I rescued her from her mundane parents," Magnus said, his voice sounding very far away. "They didn't want her and they were going to do anything they could to get rid of her. It was the happiest day of my life." The words still evaded Alec, and it seemed like the harder he tried, the less he could think of to say. "I want to go to bed now, Alec," Magnus said suddenly, getting up from the bed. Alec couldn't find it in himself to argue, so he simply nodded.

When Magnus climbed in bed beside of him, Alec immediately wrapped his arms around Magnus, who automatically leaned in to him as though his life depended on it. It was then that Alec realized that he was going to do anything he could to help Magnus heal, no matter how long it would take him to figure out exactly what he needed to do.
