"Magnus!" I call, running across the grass, which is very difficult in the silver and midnight blue gown that I'm wearing right now. It's absolutely beautiful, but not easy to move in. I have to hold up the heavy fabric so that I can run successfully. The sky is the same shade of blue-grey as my eyes, and, for once, it doesn't seem like it could rain at any minute. I'm wearing my pair of black high top converse under the dress, since I haven't been able to wash the blood off of my combat boots after Camille and her brainwashed minions kidnapped me. My hair is down in soft curls, which look better than I've ever been able to do them. Jessamine taught me after she told me that my curls were 'pathetic at best.' They fly behind me as I run to Magnus, who looks at me in surprise.

"You." He says, squinting his eyes. I can tell he's trying to remember who I am, and I sigh impatiently.

"Your crazy vampire girlfriend kidnapped me and gave me to you as a present?" I remind him, and see the spark of recognition. He nods thoughtfully.

"Rey, wasn't it?" He asks, looking at me curiously with his gold and green eyes.

"Actually my full name is Aurelia. Rey is a nickname." I explain. "Magnus, I really need your help."

"And why should I help you? The last time I saw you, your little Nephilim freinds tried to kill me." Magnus says, raising an eyebrow.

"Because if you don't, you will lose something that will be very important to you in the future." I say, thinking of Alec. If Tessa doesn't come, then Cecily might not marry Gabriel, and Alec might not exist. I can't exactly tell Magnus this though. "Oh, Magnus, please!" I beg.

"I will require payment." He says, looking at me with a bored expression.

"What is it that you want?" I ask, not wanting to say that I'd give anything. When people said that in the movies, it never ended well.

"Your necklace. The jewels on it are precious to Shadowhunters." Magnus stares down at my necklace, and I follow his gaze. Jem had given it to me a few days ago, saying that Shadowhunters held a deep love for these rare gems. He had said his love for me, though, was much deeper. I took a deep breath and nodded.

"You can block people's memories, right?" I ask, as I unclasp my necklace. He nods. "Well, I need you to block the memories of everyone at the Institute. All of their memories of me." I say, my eyes flicking up to stare at Magnus. His own eyes widen when I say this.

"Why on earth would you want to do that?" He asks.

"Because I'm not supposed to be here. I have messed up their story and now I've got to fix it." I look back towards Will and Jem. Will is staring suspiciously at some ducks, and talking to Jem, probably about how vicious they are. Jem nods, a look of amusement on his face. "Do we have a deal?"

"If this is truly what you wish, then yes. We have a deal." Magnus says, and I hand him the necklace.

"Come on. You have to get into the Institute and I have an idea about how you're going to do it." I say, walking back towards him. "Jem! Will!" I call, and they look over. "This is Magnus Bane. Charlotte invited him over for dinner, remember?" I say, and elbow Magnus in the ribs. He grumbles and snaps his fingers. After a moment, Jem nods.

"Right." He says and stands up. He takes my hand. "We should be getting back now." Jem says and I try to smile at him, but when I know what's coming, it's hard. Magnus follows Jem, Will and I back to the Institute. Charlotte and Henry are down in the lab, where we left them.

"I'm going to go tell Henry and Charlotte that we're here, okay?" I say and beckon for Magnus to follow. I close the door to the basement, and turn to Magnus. "I'm going to distract them, can you do the spell?" I inquire, and Magnus nods. I turn and walk down the stairs.

"Over here!" Henry calls and I follow his voice, trying not to step on the pieces and parts that are lying on the ground. Something has steam coming out of it and I make sure I step as far away from it as possible. I see Charlotte standing next to Henry, who is tinkering with something. I take deep breath, knowing that I hate goodbyes.

"I just wanted to say that I'm so grateful for everything that you have done for me. You two have been so kind to me, and I cannot repay you for it." I say, and they look at me with affection.

"Aurelia-." Charlotte begins, but suddenly she falls to ground. Henry turns looks over surprised, but soon joins his wife on the floor. I cry out and run to them, dropping to my knees.

"Relax." Magnus says. I jump back, not having noticed him. "They'll wake up soon, so you better move quickly." I nod, and stare sadly at Charlotte and Henry. I meant every word that I had just said, and I will miss them terribly. I stand up, and rummage through Henry's desk until I found what I was looking for. A white bag that contains the jewel that brought me here. Then I get an idea. Yes, I know my ideas sometimes are a bit crazy. I grab a pen and a small piece of paper, and scribble my address, my name and the date August 6th, 2015. I grab the bag tightly, pin the scrap of paper to my dress and run up the stairs, with Magnus following me. I make sure that no one is around and step out the door.

"What are you doing?" Jessamine comes around the corner and snaps at me. I turn and see her glaring at me. I stare back at her, not entirely sure what to say. For a few seconds we stand in silence as she waits for me to answer.

"Oh, uh-." I begin to speak, but she falls to the floor. I turn back around, but Magnus isn't there. He's standing where Jessamine stood, looking down at her. I shake my head, and walk over to him, being very careful not to step on Jessamine. "Magnus, Agatha is in the kitchen, which is in that door." I say, pointing down the hall. "I'm going to go find Thomas and Sophie." Magnus nods and we go separate directions. I look upstairs, but they're nowhere to be found. I run into Magnus on the main floor, and he follows me into the library. There, I see Sophie and Thomas talking happily. I walk inside and they turn to me. "I was looking for Will." I explain, and Magnus sneaks around a book shelf, so that he's behind them. I look down at a book on the table next to me, pretending to be interested. When I look back over, they're on the ground. I run to them, and put my hand on Sophie's cheek. "Thank you for everything." I whisper to her. She has been so kind to me over the last two months.

"This looks slightly suspicious." Someone says and I jump. When I turn, I see that it's Will.

"It's not as bad as it seems." I say and stand up. "They're not dead." I reassure him, and cross the library so that I'm standing in front of him. "You have to trust me Will."

"What did you do?" He asks, looking past me at Sophie and Thomas.

"Magnus blocked their memories." I say, and Magnus steps out from behind a bookshelf. Will stares at him. "Will, he needs to do it to you too." I add quietly, and Will looks back at me.

"Why?"

"Because if he doesn't, everything is ruined. You are going to meet an amazing girl. And you're going to fall in love with her. You're going to love her more than anyone else in the world, except Jem of course. But you won't if you don't forget me." I look at him with such urgency that he looks away. "Do you trust me Will?" I ask softly.

"Of course." His steady blue eyes meet mine. He steps forward, pulling me into a hug. It surprises me at first, but then I hug him back tightly, feeling tears form in my eyes. I bury my face in his shoulder. "I will miss you terribly even though I won't." He says, and when I pull away, there's a spark of amusement behind the sadness in his eyes. "I never thought their could be a girl like you. And I think the world needs more girls like you. Girls who laugh loudly, and sing and dance, girls who can save themselves and are brave. Girls who are willing to sacrifice so much for those they love." He says, and I feel the tears threatening to fall.

"I do love you Will. And I love Charlotte and Henry and Soohie. And I will miss you all so much. Oh, Will, if I could have you remember only one thing, it is how amazing of a person you are. Your heart is more beautiful than almost anyone's in the world." Our hands are clasped together, and I never want to let go. My best friend. My Will. "Goodbye, William Herondale." The words hurt me as I say them.

"Hwyl fawr, Aurelia Rose." He answers, his voice full of pain. Magnus comes over and places his fingers on Will's forehead. I don't let go of his hands, as he falls into the chair next to him. His fingers let go of mine, and I bite my lip to keep myself from crying and wrapping my arms around him. Instead, I turn to Magnus.

"I'm going to get my things. Can you hide Sophie, Thomas, and Will?" I ask and Magnus nods.

"You are very brave." Magnus says thoughtfully as I'm about to leave the room. "You're the only one who is going to have to deal with the pain of losing someone. Not many people would make that sacrifice."

"I would do anything for them." I answer, knowing that this is true. Magnus walks over and puts the necklace that I had given him as payment around my neck.

"Here." He says, and I look at him gratefully. I exit the library and run up the stairs to my room. I quickly pack up all my suitcases, and carry them downstairs, moving very slowly and awkwardly. But, with three suitcases, it's to be expected. I drag them into the library and put them on the ground. I shake the portal jewel out of the bag and onto the floor, being careful not to touch it.

"Aurelia?" I turn, and see Jem standing in the doorway. He sees my suitcases and closes his eyes. "You're leaving."

"I don't want to," I say quietly, my voice shaking. "But I don't have I choice." I have to shut my eyes tightly to keep my tears from spilling down onto my cheeks. When I open them again, Jem is standing in front of me. I step forward slowly, letting him hold me. I begin to cry, and press my face into his shoulder.

"It's alright...it's alright darling..." He murmurs to me, but I can hear his voice shaking. I sob harder, but I manage to pull back and look into his beautiful eyes. They are shining with tears, and one falls. I brush it away gently, and let my fingers rest on his cheek. My heart feels like someone has cut it out, stuck pieces of glass in it , and sewed it back into my chest, just to torture me. What kind of cruel world is this? Where you are given something so pure, so full of bliss, so perfect. Where you get just enough time to know that it will be more precious to you than anything else life could offer. Where it is ripped away in one unforgiving moment, leaving you falling into a black oblivion from which there is no return. How am I supposed to leave him? How am I supposed to say goodbye? I have always believed that the saying 'my heart is breaking' was something that described an emotion. But the physical ache in my chest as I realize I will never see Jem again proved me wrong.

"I love you James Carstairs. I love you with every fiber of my being. I love you more than I have ever loved anything and I will never love anything as fiercely or as truly as I love you. You showed me something that I never thought I would find. Maybe I was selfish and weak. Maybe I should have known better. But I don't regret it. I don't regret it because you won't hurt. Because I've found a way for you to..." A sob shakes my entire body, and I fall towards Jem. I kiss him, softly and sadly and fiercely all at the same time. I feel both his tears and mine resting on my face. I drown myself in the moment. I memorize the way his eyelashes feel against my skin. I memorize the way his silver hair glows in the dim light. I memorize the way his lips feel against mine. I memorize the feel of his finger tips resting gently on my face.

"Aurelia, I can't do this. I can't...I can't live without you. You are...oh there aren't words to describe how much you mean to me. How am I supposed to go on with my life, pretending that you never came, that you never made me feel all this? Emotions stronger than I ever thought possible." Seeing Jem cry is one of the worst things I have ever seen. It's not that he isn't beautiful when he cries, for he is always beautiful, but the fact that he is in pain. To know that I am the one who is causing him such pain is torture. He is like an angel. And angels aren't supposed to cry. What am I, then, for making an angel cry? Something more awful than I realized. "Oh, I would die tomorrow if I could only have you by my side for one more day. I don't want a life if it's one without you. I need you. I love you too much to let you go." He whispers to me. "I'm such an awful person for this. For wanting to keep you to myself."

"Oh, no, love. You are the most amazing person in this world and any other. Which is why...why I'm doing this." I pull away. He looks at me, confused.

"What do you?-." He's cut off as he falls into my arms, unconscious. Magnus stands where Jem was, and I know that the spell has been cast. The thought of Jem not remembering me breaks me. I fall to the floor holding his body tightly in my arms. "I'm sorry..." I say, sobbing. "I'm so, so sorry...Jem. Jem." I say his name, and some part of me wants him to wake up and see me. Wants him to remember everything. Wants him to remember how much I love him. I have given my heart up completely to him, and now, I have to take it back. But once you give away your heart, you can't get it back how it was before. You get it back with every happy memory lodged inside it, a constant reminder of what you have lost. You get it back with the scar that runs down the middle of it, that appeared after your heart was torn in two so violently that it shook your entire being, down to the very core of your soul. You get it back as you hold the person you care about so much that they are the base of all your thoughts, hopes and dreams in your arms, feeling despair stronger than you have ever felt, because the only time you will ever see them again is when you fall asleep.

"Aurelia, everyone will wake up soon. You have to go." Magnus says quietly, his cat eyes watching me. I brush back Jem's silver hair with my hand.

"I love you." I say softly, and that makes it all better. Maybe I will never see him again. Maybe he won't remember me at all. But he will be with Tessa. I fixed it. I fixed the story. I fixed his story. And I have to accept that it was a story that I was not a part of. I stand up and walk towards the jewel. I touch it gently, and a swirling light appears on top of it, growing bigger and bigger. Then I remember something. I pull the piece of paper off of my dress and give it to Magnus. "Go to this address on this date." I instruct, and he nods. "If I'm not there...I'm probably in another dimension." I manage to say. My luggage bags fall into the portal, and I stand facing it. Once I go through, I will never be able to get back. Not only will distance separate Jem and I, but time and space as well. I stare down into the red light, my pale blue eyes sparkling with tears and sorrow, my dark hair whipping wildly around my face, my goodbye still on my lips. And I jump.
