Alec could honestly say that time travel isn't the weirdest thing that's happened to him. Okay. It all started when Magnus was teaching Max how to create a portal.
"You got it Max? We're just going to portal Dad to the Institute," Magnus said, kneeling beside Max. His son gave a shaky nod, raised unsteady hands, and squeezed his eyes shut in concentration. After a few seconds, a purple vortex appeared, much to everyone's excitement.
"I did it! Papa I did it!" Max's eyebrows were furrowed as he struggled to concentrate through his joy.
"Great job, Buddy! I'm proud of you." Magnus' eyes were filled with tears. "My son just created his first portal."
Alec beamed at the pair from where he was sitting on the couch. "Congratulations Max. you did it." Alec stood up and walked to them. He stopped on Max's other side and said, "Well what do you say, can I go through it yet?"
Max gave a hesitant nod. Alec ruffled his son's hair as he started to walk.
"Catch you on the flipside," he said with a wink and just like that Alec walked through the portal
In all of the excitement no one noticed that the portal was swirling backwards, almost as if it was going backwards in time.
As Alec stepped through out of the portal he knew that something was wrong. He knew because he was staring straight into his own eyes, his own face.
"Well fuck"
Alec sighed as the shadowhunters all pointed their weapons at him. "I guess I should probably explain how I got here." Everyone was looking back and forth between the two Alecs. "First off, no I am neither a demon nor am I Valentine."
"Oh yeah? Prove it." Jace's hand was resting menacingly on his sheathed sword.
" You're afraid of ducks." Jace recoiled as Alec spoke. "Izzy's afraid of rats." Now it was her turn to recoil. He gave a chuckle. Oh the things I could tell you about me he thought "And I am afraid of spiders."
"Big deal, you can tell us one of our fears. How is that supposed to make us trust you?" The Alec that was here said.
Alec suddenly understood Clary much better about the whole Valentine's daughter thing. Alec rolled his eyes and said, "Fine then." He thought for a second then turned to where Izzy stood. "Heart and soul. I found my heart and soul"
Izzy took a step back, shocked, then the widest grin stretched its way across her face when she realized what he had said. "I'm so happy for you big brother." Izzy practically leapt into his arms, almost knocking them both to the floor with the ferocity of her hug.
"Okay Izzy's convinced, but what does heart and soul mean?" Clary asked.
He sighed and said, to the shock of some, " Right before the parabatai ceremony, I was having second thoughts." The other Alec jerked forward to try and stop him from talking. Alec kept talking anyway. "Izzy came to try and figure out why I wasn't getting ready for the ceremony. We talked and she got my head out of my ass about something and she said 'You deserve someone who is going to love you heart and soul.'"
"Wait is this about your… " Before Clary could finish her sentence, she was cut off by Alec's sharp reply.
"Yes. I made it a bigger deal than it really was because he already knew about it. And now you'll drop it because I got over it, Red." He knew that she was asking about his crush on Jace.
Past Alec turned and looked at Alexander with a panicked look on his face. "He already knows?"
Alec sighed and replied "Yeah he's known for years. Anyway, since I convinced you that I am in fact not a demon or Valentine, what are we going to do about the name situation?"
Everyone was looking back and forth between the two Alecs.
"Well this time's Alec can stay Alec and you can be Alexander," Clary suggested.
"Okay now that that's sorted, tell me everything about the future." Izzy demanded with a smile on her face. Her only response was Alexander's laugh.
