On a still night a young teenage boy covered in silk sheets and a black comforter rattle uncontrollably in his sleep. The boy had a tight face, clenching his eyes and teeth together, sweating buckets, that seeped into the silky white sheets beneath him. Suddenly he awoke breathing hard repeating the words, "I remember". In a flash the boy rushed out of his bed, still a sweaty mess, and raced down the corridor and knocked one of the many wooden doors that lined up against each other. He knocked hard and continuously until the door flew open revealing a slender and sexy girl, with raven hair and dark eyes, wearing very short shorts, the kind most girls wear to sleep in, along with a white tank-top.

"whaa...", she stopped mid-sentence as she fully opened her eyes and allowed them to see the man standing before her. "Simon…." She began.

"I remember", Simon said almost overly excited by the fact. "I remember everything now", he smiled, "My life is back to me Izzy. I just had to tell you. I love you"

For the past few months since Magnus and Isabelle had revealed themselves to Simon, explaining to him about his life and inviting him to come with them and become a shadow hunter, Simon has been suffering through countless hours of training and lessons with Magnus, so that he could retain all of the memories taken from him by Asmodeus in the Demon Realm. Magnus had told Simon that nothing was for sure and that he should not expect all of his memories to return. Simon, however, did not care and wanted to close the holes that were left in his heart. For months he felt as if something was missing in his life, and it wasn't until Magnus and Isabelle had come to him that he knew what is was. But it was something in the way these people, these shadow hunter people said his name that made him want to believe in them. So he accepted and attended the party everyone was having by a lake near Luke's old cabin. Before that, however, Magnus did a spell on Simon to turn him into a shadow hunter and allowed him to retain a few fuzzy memories of certain people, so that at the he would not be completely overwhelmed.

The months had been hard and strenuous for Simon but he wanted to be the man that everyone said he was: A hero, a warrior, and a friend. Most of all he wanted to be the man whom Izzy had fallen in love with. Over the months he had continuously remembered things and began to rebuild relationships with people whom he cared deeply for; Isabelle, Clary, Jocelyn, Luke, Alec, Magnus, and even Jace, who was now going by Jace Herondale. The Clave had strangely accepted Simon, mainly because he helped defeat Sebastian and the countless testimonies on his behalf. They sent him to the Iron Sisters in Alicante to be properly runed, as they did with newborns. Now in the doorway of the most beautiful girl he had ever seen Simon had permanent runes stretched across his body, looking like a true Shadow Hunter.

Simon looked at her glimmering black eyes in the moonlight, getting anxious due to her lack of response. Did she not love him, but they did DTR, as Clary put it. He thought they were boyfriend and girlfriend now, although it was several months ago. He was beginning to get cold feet and run down the hall back to his room where he would wallow in self-pity and humiliation, when Isabelle grabbed him by his shirt that read THE PEN IS MIGHTIER THAN THE SWORD, even after all of the craziness of the past 8 months Simon still kept his t-shirts, and kissed him lingeringly as if she had waited years to finally do it. Simon deepened the kiss while slowly moving into her room. Though the lights were turned off Simon could make out a few things, such as the hot pick colored rug and bright colored dresser that held perfume, make-up and blades on top. And her bed that she was pulling him towards, that had a bright pink comforter and dark sheets underneath. His heart was pounding and he was surprised at this feeling, the sensation of a heart pounding over again, the ringing in his ears, and for once as he kissed Isabelle he did not smell her blood.

They both fell back onto her bed and went at each other like animals. Isabelle's soft lips crashing into Simon's as they took off one each others clothes. Simon was shifted under Isabelle and ran his hand up her now exposed spine, pressing himself against her. He began to realize where this was going. He sat up and lifted Isabelle on to his lap, her legs wrapping around his waist for support. Isabelle felt Simon's uneasiness as he sat up, and lifter her head away from his warm tender lips, and looked down at him. As she stared down at him with gleaming eyes and as he stared up at her with his brown shining eyes, they both thought about how much they loved one another. The window over Isabelle's allowed the moon shine down on them as Isabelle said, "What is wrong? Don't you want to?".

"Yes, of course", Simon said immediately making sure that Isabelle did not think he did not want to "be" with her,"but only if you want Isabelle. I do not want you to feel obligated to me to do this right now if you are now ready. It is true that I love you but it is also true that even if we do not do this right, even if i had to wait a hundred years until you are ready I would still love you."

Isabelle considered this and put her hand on his cheeks and gently squished them together, protruding his lips at towards her. She kissed him tenderly and longingly and said, "I want to. And I want it to be you and only you," she looked like a queen to Simon, "and I know I have never said this but, I LOVE YOU TOO". Simon's heart fluttered and he nearly cried from hearing those words, probably would have if not for Isabelle crashing another kiss down on him.

They proceeded and continued to strip each other until they wear down to their underwear. If Simon thought that Isabelle was a queen with her clothes on then she looked like a goddess with her clothes off. Simon reached up and touched over the back of Isabelle's lacy black bra and unhooked it letting it fall to the ground, releasing Isabelle onto Simon's chest. They have never been closer than what they were at that moment, and their heart beats pounded so hard they became one hard and thunderous sound. Isabelle and Simon had never been so happy than what they were at that moment, together, naked, and nothing between them.
