AN: Alright, so this is my first time publishing on this site. This is, by far, not the first fanfiction I've ever written, but it's the best. I've actually written about 12 chapters of this already that are up on Instagram so if I inevitably forget to update on here feel free to check this out on Instagram, account nane's in my profile. There are actually going to be 2 versions of this, one that's just Mortal Instruments and one that's a Supernatural crossover. Try not to let that be too confusing. This one is the Supernatural crossover. The Supernatural characters don't come in until MUCH later though, so don't hold your breath. Also, I put myself and a couple other people I actually know in real life in this, which is weird but it works. I have no beta, all mistakes are my own. Ok I'll stop rambling now. PS, not all my author's notes will be this long.Alec lunged forward and stabbed his seraph blade into the demon. The ichor seemed to go right through him and pain burned his body for a moment. He cried out and dropped the blade. The pain stopped as soon as it had come, leaving Alec breathless. He picked up his blade, clipping it to his belt.
Magnus looked around in confusion. "Where did Alec go?" He asked. Alec waved a hand in front of his face. "I'm right here, Magnus," he murmured. Magnus couldn't see him though, and Alec was thoroughly confused as to why he didn't acknowledge his presence. He walked over to Clary and Jace. "I don't know, Magnus. Our Parabatai bond feels...wrong somehow. He's not dead, but I don't know where he is," Jace said, looking utterly dismayed. "I'm right here!" Alec exclaimed. Then, he realized with a jolt, that they couldn't see him.
"Should we go back to the institute and try to figure this out?" Izzy suggested. Everyone nodded and gathered, starting to walk away. Alec walked down a random street, waving his hand in front of mundanes faces' to see if they could see him.
Ryn, Elle, and Jules were just three college girls at NYU walking home from class one Friday. Ryn, of course, was a philosophy major. She had no idea what she was ever gonna do with that degree, granted, but it was what it was. Elle was a meteorology major, while Jules was studying psychology. And they were all three total Shadowhunters fangirls. They had just started laughing at one of their many inside jokes when Ryn stopped, staring ahead with a confused expression. "Ryn, what is it?" Elle asked. "What do you think he's doing? Or who he is, for that matter?" Ryn asked, pointing down the street. "Who?" Jules asked, confused.
Alec noticed a girl in a trio down the street, apparently pointing right at him. He jogged down to her, frazzled and confused. "You can see me, right?" He asked desperately. Ryn nodded. "Yeah, why wouldn't I be able to? Also who are you? You look really familiar," she responded. Alec sighed in relief. "Oh, thank the angel," he mumbled. Just then Elle gave Ryn a quizical look. "Umm...Ryn? Who are you talking to?" She asked, looking at Ryn like she was crazy. Ryn raised her eyebrows and gestured to Alec. "Uh, him." Alec gave her an I-told-you-so look. "My name is Alec," he responded to her earlier question. Ryn gasped and smiled hugely. "Alec? As in Alexander? As in ALEXANDER GIDEON LIGHTWOOD?!!??" she exclaimed squaling in delight. "Err...um...yeah. How'd you know?" He responded. "You're only, like, the most adorable cinnamon roll in the whole Shadowhunters series! Wait, oh god, yup, I'm definetly hallucinating. You're just a book character, you can't really exist. Oh but you seem so real!" She gushed. "Wait, Ryn, are you talking to your imagination again?" Jules asked, shaking her head disapprovingly. "No! I'm real! Please, I need your help! And what do you mean, book character?" Alec asked, running a hand through his hair in frustration. "Aww, you're so adorable when you're clueless. Ok, fine, how can I help? Might as well see," Ryn said, grinning. Alec sighed in relief. "Ok, follow me, I'll explain on the way," Alec responded. Ryn nodded and started walking with him. Elle and Jules shrugged and followed; they were used to Ryn's antics by now. She is a philosophy major, after all.
Wow this is so short...the chapters get longer, I promise. Also sorry for the really weird formating on some of this.
