Chapter Eight-Final Chapter

Alec rested his head back against the worn bricks that made up the small cell he was sitting in. His legs were sprawled out in front of him the best he could as his wrists and ankles were shackled together and only a length of chain that allowed him to move. He was exhausted after everything that had been happening, he had been hurt numerous times and he couldn't even remember the last time he had a good nights sleep.

However, no matter how heavy his eyelids were he refused to sleep here, remembering what Jace had told him one night on Magnus' balcony. If you slept while in the cells of the City of Bones then your worst nightmares would come to life, in other words don't ever sleep there if you can avoid it. Alec just hoped Emma had gotten to Magnus safety and the Warlock would understand why he had to leave and would keep her safe. Figures he would get rid of Pierce but now he had to deal with the Clave.

"You are different than others see you." A Silent Brother's voice echoed in his head, Alec looked at the door of his cell to see a Silent Brother standing there.

"I suppose I am." Alec conceded unsure what the Silent Brother was getting at.

"The Warlock child you were with… She is safe with the High Warlock, while you will not be if the Shadowhunter's ask you the wrong questions during your interrogation. We shall endeavor to keep the secrets from your time a secret the best we can. We will intervene if that is needed." The Silent Brother spoke into Alec's mind as he unlocked the door to his cell. Alec used the wall the best he could to stand on his own feet and shuffle out behind the cloaked figure.

"Thank you, it's more than I expected to be honest." Alec chuckled as they slowly made their way to where the Soul Sword was resting.

"You are a good man Alexander Lightwood and this is not the time nor the place for your story to end." The Brother said mysteriously before falling silent as they entered the room where a younger Maryse was waiting alongside Hodge and a few other Shadowhunter's Alec didn't recognize.

Alec's blood boiled at the sight of Hodge before his shoulders slumped as he realized even with everything he did, Alec still considered him a part of his family because, in the end, he did save Jace in his own way in the City of Bones.

"Pick up the Soul Sword and we will begin." The Silent Brother stated for all to hear, Alec shuffled over to the sword and grunted as the heavy weighted sword was placed in between his shackled hands.

"What is your name?" Maryse stated firmly, her fingers curled around the hilt of her blade as she inspected Alec more closely. Alec kept his mouth shut before gasping as pain shot through his system but he gritted his teeth to keep himself silent.

"Your name!" Maryse snapped as Alec cried out in pain as the Soul Sword burned him from the inside as he tried to resist its power, to tell the truth.

"Alexander Gideon Lightwood!" He finally cried out and the pain stopped, letting him slump in his chains breathing heavily.

"That's impossible!" Maryse paled at his words and the way the sword reacted.

'The Soul Sword does not allow the person holding it to tell a lie. He is Alexander Lightwood.' The Silent Brother's voice rang in all their heads.

"How is that possible?" Hodge looked at Alec with far too much interest.

"A combination of a mission and wrong place, wrong time," Alec said honestly and breathed out in relief when the sword didn't cause him pain.

"What happened to our Alec then?" Hodge pressed on and Alec actually winced back at the genuine care that the blond was radiating.

"I honestly don't know, but if he is where I think he is… My family will take good care of him." Alec promised not knowing why he cared about easing the worry of a traitor, but this was Hodge. The man who was more of a father to Alec than his actual father was.

"That's something I guess," Hodge muttered as Maryse stepped forward obviously had enough with idle talk.

"The Warlock child you were with, what do you want with her?" Maryse asked as she took in the sight of her 'son' with a look of disdain, but it was nothing new to Alec.

"We need to help each other," Alec said simply and adjusted his hold on the sword, pleased that it hadn't pained him again.

"Help how?" She pressed and Alec refused to tell her anymore and readied himself for pain, but before the sword could start to burn him a Silent Brother pulled it out of his hands.

"This integration is over." The Silent Brother escorted Alec towards a hallway.

"No, it is not! Get him back here NOW!" Maryse shouted but Alec couldn't see her anymore as he shuffled down the hallway of the City of Bones.

"Why are you helping me?" Alec quietly asked the Silent Brother as they moved through the darkened halls.

"We preserve time when needed and your Warlock is waiting outside of the City with the young Warlock child, the timeline will be righted and we will erase the Shadowhunter's memories of ever meeting you." The Silent Brother stated and Alec felt himself relax at the knowledge this whole time travel ordeal will be done with soon. He desperately wanted to curl up with his Magnus and sleep for a week.

"Thank you, just… Thank you." Alec bowed in respect after the Silent Brother snapped his shackles off and Alec got an incline of the brother's head in return. Alec blinked a few times as he stepped out of the City of Bones, the moon was high in the sky above them and it illuminated both Magnus and Emma.

"Alec!" Emma flew at the Shadowhunter, throwing her small arms around his waist as she clung to him.

"You got to Magnus safely then, I'm so glad you're alright Emma." Alec knelt down and held the girl close before lifting her up to settle her on his hip as Magnus approached the two with a soft smile that made Alec's heart beat faster.

"So this is who you were talking about. Well, I bet you could imagine my surprise when this little lady appeared in my loft babbling about how her tall friend Alec was taken away by other Shadowhunter's." Magnus ran a hand down Emma's back and the young Warlock sighed softly as she nuzzled against Alec's neck as she relaxed further.

"I didn't want you to get involved." Alec offered up weakly.

"I understand why, time travel is a tricky thing." Magnus hummed in agreement and Alec let out a soft puff of breath.

"I can see why you wanted to keep me in the dark, more so as we are together in the future," Magnus said casually as he waved his glowing hands to form a portal, Alec just smiled sheepishly already figuring that Magnus knew that secret.

"Shall we Alexander?" Magnus purred using Alec's full name for the first time and Alec let out a shudder before following Magnus into the portal.

"Alright, sweetie can you focus your magic like I showed you before?" Magnus knelt in front of Emma who Alec had placed on the ground once they were safe inside of Magnus' loft.

"Uh-huh!" Emma chirped happily as she focused and her magic started to swirl around her. Her adorable face scrunched up as she focused and worked her magic to the best of her abilities.

"Pierce sadly will go back with you two, it's the way this spell works so be careful Alexander." Magnus let his own magic mingle with Emma's and Alec watched as the two worked together in silent awe.

"I'll protect her," Alec promised and Magnus flashed him an almost sad smile.

"Do not forget to protect yourself as well Alexander," Magnus said softly and Alec nodded mutely as there was a lump in his throat at the soft words and their meaning.

"Thank you, Magnus, I know I was kind of an ass well a giant one after all the help you gave me…" A pair of soft lips pressing against his cut off Alec and he sighed happily at the familiar touch.

"Consider that payment and a promise that I will find you and we will have that love you spoke of," Magnus swore to a now blushing Alec as a white portal swirled to life.

"You'll have to promise not to give up on me when we meet I'll be working on some stuff but I promise it will be worth it Magnus, I will always love you." Alec cupped Magnus' cheek softly before stepping into the portal, Emma glued to his side and the portal flashed and the resulting light all but blinded Magnus who threw his hands up to protect his eyes.

"Hello!" A cute, high-pitched voice said causing Magnus to look down at a child who was very clearly Alexander.

"Hello there Alexander, did you enjoy your time in the future?" Magnus knelt down to eye level with his future lover who was far too adorable for his own good.

"I did! We even went to Italy and you changed your hair color and I love your cat eyes." Child Alec started to babble as he touched the Warlock's facial hair gently and in a familiar movement.

"Why thank you, little Angel, I'm glad you are safe and sound." Magnus knew what he had to do to keep the timeline intact so he settled for pulling the already runed child in for a tight hug.

"You're not as shiny today Magnus, I like it when you're shiny," Alec mumbled as Magnus worked his magic, a mist of blue light appeared around the duo and working out of the loft to search out for those who had encountered with adult Alec that he knew of.

Alec let out a soft yawn and dozed off against Magnus' neck and the Warlock pressed a kiss to his forehead as he opened a portal, sending the dozing child through before he forgot about Alexander fully.

"Until we meet again my little Angel," Magnus whispered before the spell did its work and he fell into the darkness to wake up with no memory of his encounters with Alexander of the future.

~~/~~

"Stay back!" A far too familiar voice brought Alec back to consciousness along with the cold touch of metal against his throat.

Alec blinked as he realized he was being used as a human shield to fend off an angry looking Magnus Bane. Magnus' cat eyes were on full display and red bursts of magic sparking from his fingers as Emma clung to the Warlock's legs, peering around to look at Alec with wide, worried eyes. Clary was holding her own Seraph blade high to add extra protection for Emma just in case.

"Magnus made me spare you and this is the thanks we get Pierce?" Alec rasped out as he put the pieces together.

"Shut up Lightwood or I'll make good on my promise to take your head!" Pierce snarled but Alec could hear the undertone of panic.

"You are not going to be walking out of here alive if you even try." Izzy's voice came from the other side of the room and the familiar crackling noise of her whip echoed in the room.

"Release my brother right now or you'll be the one without a head," Jace ordered from where he had snuck up on Pierce, pressing the tip of his own blade to the middle of Pierce's back.

Pierce huffed annoyed but dropped his blade and Alec stumbled away from the Circle member and right into Magnus arms who used one arm to hold the eldest Lightwood to his side protectively as his free hand flared with his magic as a portal appeared under Pierce's feet. The man yelped as he dropped into it before it winked out of sight.

"Are you hurt Alexander?" Magnus looked his love over with worried eyes as he held him close.

"I'm fine love, your past self is a good healer," Alec promised and finally, finally kissed his Magnus.

"Yes, yes, how adorable but get over here." Jace hauled Alec in for a tight hug once the two lovers parted and exchanged soft and somewhat giddy smiles.

"Good to have you back man, little you kind of freak me out. I'm used to you towering over everyone." Jace whumped Alec on the back before stepping back to let Izzy all but tackle their big brother.

"You were so unbelievably cute Alec! I have so many pictures to prove it now, but I'm glad you're back to you." Izzy clung to her brother who kissed her hair with a soft laugh.

"I'm glad too, seeing you guys as kids kind of threw me for a loop too." Alec chuckled at the faces his siblings made his words like they were trying to remember something but couldn't.

"Simons says you saved us when we were kids, but you know I don't remember but thank you." Clary held her pinky up to Alec with a small smile on her lips.

"Pink promise Fray." Alec hooked his pinky with her's and she laughed in delight at how he understood the mundane reference.

"Um, Mr. Alec? Thank you for saving me and protecting me even though I caused so much trouble." Emma tugged on Alec's pants, gnawing on her lower lip as she looked up at him with Bambi eyes that reminded Alec of Izzy when she was younger.

"You are most welcome, I'm just glad you're safe." Alec knelt down to look at Emma, his voice gentle and she nodded rapidly before tossing herself at him for another hug.

"Magnus, do you think we have room for one more for the night?" Alec turned to his boyfriend who was watching the reunions with a happy look on his face.

"Of course Alexander, first door on the left," Magnus replied as he snapped his fingers. Alec nodded his thanks and headed towards the mentioned room to put the half-asleep girl to bed.

"Take care of our brother Magnus." Izzy patted Magnus' on the shoulder and the Warlock looked at the Shadowhunter's in surprise.

"You're not staying? You know you all have rooms here?" Magnus had no idea why they were willing to let Alec out of their sights; he planned on having Alexander in the loft for a solid couple of days at the least.

"Nah we are going to help Maryse and Lydia deal with our infestation, but we need you to keep Alec out of there until it's safe." Jace shook his head as the trio headed towards the front door.

"Perhaps I'll take him to Italy again, maybe this time he will remember it." Magnus chuckled lightly as he saw the three off before throwing his wards up so nothing and no one could enter and pose a threat to his Alexander.

"She's out like a light, thanks for making room for her." Alec stepped back into the living room, covering a yawn with his hand.

"I think it's time for some rest, you can tell me about your adventures in the morning." Magnus pulled his love into his arms and steered them towards their bedroom, Alec going willingly even if his steps were sluggish.

"Where are the others?" Alec asked as he slowly blinked when Magnus snapped his fingers and they both were in their comfortable sleep clothes.

"At the Institute, they all but ordered me to keep you here until you are recovered fully. Time travel and I'm assuming injuries can take a lot out of you." Magnus guided Alec into their bed, sliding in next to his lover pulling the sheets up to keep them warm.

"Yeah, okay… I love you Mags." Alec muttered as he fell asleep, curled towards Magnus and his comforting presence.

"I love you too my little Angel." Magnus kissed Alec's cheek before tucking him under his own chin and holding him close, as he finally felt complete with Alec in his arms here in his arms and decided he would work on retrieving his memories in the morning.
