A/N: Hello my wonderful followers, readers, Supernatural and Shadowhunters/mortal instruments fans! It's been quite a while since I posted anything, and I'm sorry for that. But I'm back! Although I have hit a wall with my other fanfics. But I haven't given up on them! This is a crossover with supernatural and Shadowhunters/mortal instruments. Now I have no idea where this story is going, I've been Inspired by The Red Scrolls of Magic, and I'm only one chapter in! Fully expect that my favorite characters, Magnus Bane and Dean Winchester, is going to play a very big role in this story. lol. I took inspiration from both the TV show and the book series of Shadowhunters/mortal instruments. Now be warned, I haven't read all the books and I haven't finished the show. I've read the first book, started the second but got distracted by The Red Scrolls of Magic. But my friend pretty much told me everything that happens in the series and others books in the same universe, so I have a vague idea what happens. So let's just say that Andromeda, (Andra) my OC, was a part of everything that happened like everyone else with her own parts to play. As for supernatural, it's from season 14. But for obvious reasons that will be revealed in the first chapter, It's not going to follow the plot of season 14. As for Shadowhunters/mortal instruments, I will try to keep as close to canon with the characters as possible. And I'll try to keep the characters in character. But this is my first time writing them, so please let me know if they start to drift out of character. XD. Everything that happened up into this point was canon, but from this point on it's going to be it's own plot. However, I do welcome anyone telling me what happened in certain important parts in the Mortal Instruments and The Dark Artifices, so I can accurately describe them in later chapters. Again for reasons that will be revealed. And don't worry about any spoilers, I know too much as it is, but I'm still gonna read them anyway. XD.

Carry on wayward supernatural fans, and happy patrol shadowhunters.

Andromeda Lightwood, the superhero of emotional support, never had the luxury of pondering romantic love and her own feelings. Nope, she was too busy juggling the weight of the world on her shoulders, like everyone Involved, from thwarting evil masterminds to playing the role of a relationship counselor for the whole gang, that includes Emma and Julian. At least Mark had his shit together. Sort of.
Valentine's shenanigans, the elusive Clave reforms, and the ongoing soap opera of Jace and Clary - she's seen it all, folks. And just when she thought she could catch a break, unwanted feelings that she's been suppressing all this time decide to crash the party, right in the middle of a sparring match. Classic timing, really.
So there she is, sprawled on the floor after a well-placed kick from her parabatai, Adelynn Thorne, while the cheers of victory echo in the air. Andromeda's discomfort is practically palpable, but hey, who has time for that when there are high-fives to be exchanged with Jace, right? Classic Adelynn, too busy basking in the glory to notice her friend's internal turmoil. Ah, the joys of emotional complexity in the midst of sparring. Classic Andromeda.
Adelynn of course couldn't resist pointing out the obvious as she pulled Andromeda up, "You would have won if you weren't daydreaming, Andra."
"What makes you think I was daydreaming, Addy?" Ah, the classic banter of friends in the midst of after training – sticky hair and all.
Addy let out a snort of amusement. "Because you've been daydreaming a lot lately," she pointed out, not one to let Andra off the hook that easily.
Jace, apparently just couldn't resist the opportunity to add some fuel to the fire. "Oh, have you been daydreaming about me?" he smirked, clearly reveling in the chance to stir the pot.
Andra, not one to mince words, rolled her eyes and retorted, "You wish." After all, who could blame her for a little daydreaming every now and then? After all she's been through, a daydream or two is practically a right, not a privilege.
Jace, always the charmer, couldn't resist pushing the envelope further. "Aww," he said, throwing his sweaty arm around her shoulders, grinning mischievously. "Don't tell me you have a massive crush on me?"
Repulsed by the idea, she exclaimed, "Ew, no! That's gross!" with all the conviction she could muster.
"I'm going to try not to be offended by that," Jace quipped in mock disappointment.
With a determined huff, Andra finally managed to free herself from Jace's sweaty arm and declared, "You're like my brother! And I have better taste," punctuating her statement with a smirk.
Jace, pretending to be wounded, mused, "Words do have an effect on people." The delightful exchange of banter and sibling-like camaraderie.

...

Andra stood in front of the mirror, removing her colored eye contacts to reveal her piercing pink eyes. It was a reminder of her unique heritage as a fae Shadowhunter, a secret she had carried since being left on the doorstep of the New York Institute at the age of 12 and officially adopted by the Lightwoods at 13. As she pondered whether it was finally time to embrace her true self, she found comfort in the friendship she shared with Mark, who understood the struggles of being fae. And then there was Magnus, the only other person who knew her secret, discovered by sheer coincidence during a visit to Alec.
The weight of this long-held secret had become a burden, making it difficult for Andra to come clean to everyone. Yet, with her contacts removed and her true fae nature revealed, she stood at a crossroads, contemplating whether it was time to step into the light or continue to dwell in the shadows.
Andra found herself burdened by the weight of her secret, not even sharing it with her parabatai. The thought of keeping such a significant part of herself hidden from those she cared about weighed heavily on her. She couldn't help but wonder if Adelynn had a sense of her secret, as close friends often do. Despite this, the hardest part was keeping it from her parabatai, the one person she was meant to share everything with. The internal struggle of carrying this burden in silence was taking its toll, leaving Andra feeling isolated and conflicted.
Andra found herself lost in thought as the water cascaded over her, her mind drifting back to a time when Alec had kissed Magnus in front of everyone. The memory of that moment stirred a strange sensation in her chest, one she couldn't quite comprehend at the time. Suppressing her feelings had become second nature to her, a skill she had honed over the years. However, harboring feelings for her big brother's boyfriend was a complication she knew she couldn't afford.
As the water washed over her, Andra grappled with the conflicting emotions that threatened to surface, knowing all too well that these suppressed feelings would only lead to trouble.
Andra couldn't help but find the situation truly ironic. The fact that two Lightwoods, Alec and herself, had both fallen for the enigmatic High Warlock of Brooklyn seemed like a twist of fate. As she pondered over her feelings for Magnus, she wondered if it could still be considered a crush, especially considering that these feelings had persisted over the years. The complexity of her emotions towards Magnus, intertwined with their unique circumstances, left her grappling with a mix of confusion, longing, and a hint of resignation.
Andra stood before the mirror, freshly showered and dressed in clean clothes, her pink eyes reflecting back at her. Hesitating for a moment, she contemplated putting her colored contacts back in, a simple act that had become a symbol of the duality of her identity. With a deep breath, she made her decision, knowing that whichever choice she made, it would be a reflection of the path she was yet to embark upon.
Andra's gaze lingered on the bright blue color of the contacts. The discomfort of wearing the contact had been a constant reminder of the life she had left behind when her biological mother had left her on the Institute's doorstep. Initially, she had only worn the contacts when they ventured out into town. However, as she delved into her training as a Shadowhunter, she had made it a habit to wear them all the time, a tangible link to her past and the secrets she carried with her.
Addy and Alec's voices drew her attention. She rolled her eyes on realizing that they were having another spat, deciding not to get involved she managed to sneak by without them noticing her only to walk in the entrance to see Jace and Clary sucking each other's faces.
"Stop, your making me sick."
Jace smirked as Clary's cheeks flushed. "I'm going to remind you of that one day." Jace said as Andra moved by them.
"Whatever do you mean, golden one?" Andra drawled, opening the door.
"When this happens to you."
She froze with her hand on the handle. She's too late for that. The only man that she has feelings for was with Alec. And those two were soulmates. "And I'll kick your ass."
Jace's snort and whatever he was going to say was interrupted by the closing of the door.
Andra stuffed her hands in her pockets and started walking down the street in a random direction, contemplating the events that had unfolded. It was hard to believe how far everyone had come, and she found solace in being everyone's emotional support, a welcomed distraction from her own feelings and the secret she was keeping from everyone.
A shimmer cut through the air, causing her to stop in her tracks. It felt abnormal, like the sensation of a portal opening, or at least how she imagined it would feel. Despite the bustling city remaining unchanged, she felt something different in the air.
The screeching of tires drew her attention as a sleek black car suddenly came to a halt in front of her. Two men, one taller than the other, stumbled out in confusion.
"What the hell!?" the shorter man exclaimed, his tone filled with anger, scanning the area as if searching for any threats, while the taller man shook his head.
"Hey, you!" the short man pointed at her. "You didn't so happen to see anything?"
She raised an eyebrow, meeting the man's gaze. "Other than you acting like you're drunk off your ass? No."
The man's glare was met with Andra's unyielding scowl. She didn't have a clue who this man was, but she refused to be intimidated in the least. The tall man stepped forward. "Excuse my brother. We've had a long day."
"A long week." The shorter man grumbled.
"Don't have to be a jackass."
The man with the long hair lips twitched into a smirk, the other rolled his eyes.
Andra listened as the short man spoke. "Sammy. What's the coincidence? We're driving and go through a portal and then we're here? With her standing in front of my car?"
Sammy sighed, and Andra couldn't help but feel a sense of confusion washing over her. So that was a portal that she had felt? But why hadn't she seen anything? What warlock had opened a portal for them? And who were these men?
Andra's eyes narrowed as the short man exclaimed, "Look at those freaky ass tattoos, Sam! She's gotta be some sort of witch!"
"Excuse the hell out of me!?" She glowered, highly offended. She wasn't even going to question why mundanes could see her runes right now. "They're runes! You idiot!" The short man was extremely handsome, sure, he could be a damn male model. But he was infuriating.
Sam frowned at that, but turned his attention to his brother. "Dean, she might not have anything to do with it."
"And she might be standing right here and listening to your conversation, but please do ignore my presence," Andra quipped.
"Then how the hell did we get here!?" Dean huffed.
"Yup I'm not even here." She drawled. "Not like you almost hit me with your car."
"Jack? You know he's been having trouble with his powers." Sam frowned.
"Okay. Good luck with whatever your issue is." Andra said, stepping around the car.
"Hey, wait!" Dean called.
"Sorry! Got my own issues! Go to Magnus Bane! He might be able to help you out."
"Who's Magnus Bane?" Sam asked, causing her to stop.
"Who's -" Andra spin around and approach them. "Have you been living under a rock? I'm assuming you know about Supernatural things. How can you not know who the High Warlock of Brooklyn is?"
Sam and Dean glanced at each other.
Andra shook her head. And she had thought that alternate universe that she slipped into with everyone was bad and strange. "Okay. Yeah. You know what? I have dealt with enough freaky shit. I don't need more piled on my growing list. But who the fuck are you?"
"I'm Sam Winchester, and this is my brother Dean." The names doesn't ring a bell. "What's you're name?"
"Andromeda Lightwood. Andra everyone calls me." She frowned. "Is jack the warlock that opened a portal for you guys?"
The brothers shared a conversation with looks alone, but to her eyes, she could read their thoughts as clear as day on their faces, It was in their body language. They were deciding if they could trust her.
"Not exactly." Dean said. "Try the love child of Lucifer."
"So, warlock." She frowned, confused.
"Lucifer is an angel."
"Who fell. So technically he's a demon."
Dean ran his hands over his face. "Whatever."
Andra wasn't sure if she should take them back to the institute or to Magnus. Part of her just wanted to end this conversation and continue on her way, but there was a nagging feeling that if she walked away, it wouldn't be good.
