Okay. Here's the next chapter. I'm keeping Simon as a vampire, because I like him as a vampire.

I'm finally bringing in the TMI characters, keeping Vargas alive because I really like her character and wish she wasn't killed off as early as she was.

Anyway, here's chapter four of Changing Blood.

Destination: New York.

Magnus Bane groaned as his phone started ringing again, he had already declined the caller twice in favour of taking a cat nap with his boyfriend.

"Just answer it" Alec advised his, "It's obviously important."

"Fine." The warlock grumbled, rolling his eyes and detaching himself from Alec before answer the phone. "This better be good whoever you are."

"Long time no see eh Magnus?" Spencer's voice came through the phone.

"Spencer? Where the hell have you been, it's been at least 50 years since we've talked, and why do you sound Canadian."

"Spend almost a century living in Canada and see what it does to you" The younger warlock remarked.

"Not that it's not great to hear from you but why are you calling? You okay?" Magnus asked, he may not like having his cuddle time with Alec being interrupted but Spencer was family to him.

"I'm fine but the FBI team I'm now working with is flying down to New York to work on the recent murder cases in Brooklyn and the surrounding areas, the vamp ones. Surprised the clave hasn't tried to cover it up yet, but anyway just giving you a heads up. Scar's with me as well as a freshly turned vamp but she's keeping him controlled." Spencer told his long time friend.

"Okay thank you for the information, Can I go now?" Magnus was starting to get irritated, he had left the heater on and his apartment was starting to get warm, prompting Alec to remove his shirt and he couldn't help but stare at his boyfriend's amazingly sculpted body, resembling a greek god and the way his runes ran along his curves, it was making Magnus' imagination stir with dirty thoughts of what he could do to Alec.

"Why?" Spencer's voice cut off his nasty thoughts. "You have a girl or guy to get back to."

"Yes in fact I do, and before you ask yes I am answering this phone call while descent, we were just cuddling and watching a movie."

That's what you always say Mag." Magnus could swear he heard the eye roll from over the phone line.

"Like you and Nathen." He remarked and Spencer fell silent. "Touché. Anyway, text you when we land. Later Magnus."

"Later Spencer." With that the two hung up, Magnus smiled finally hearing from Spencer after quite some time, having missed the younger brother he once saw as a little brother now still a little brother but also a best friend.

"Who was that?" Alec asked as Magnus hung up and put his phone down,

"Old friend that I haven't had contact with in about 50 years, no idea how he got my number. He somehow got a job with the FBI and he just warned me that they're coming to investigate the vamp murders that have been going on around town." Magnus shrugged wrapping her arms around Alec again as the blue eye shadowhunter leaned into the warlocks arms.

"I'll get his number from you later, so we can figure out a way to get some shadowhunters into those crime scenes."

"Isn't Luke working on that one too?" Magnus questioned

"Yeah but Luke's been working with the NYPD for year, look suspicious if he was just suddenly bring in new people, less suspicious with the FBI." Alec smirked

"They way you strategize is just so sexy." Magnus bit his lip and stared down Alec's chest before his amber golden cat eyes met Alec's sky blue one, both men were leaning in for a passionate kiss as Alec's phone went off.

"By the angel!" Alec yell. "I can't have one night off with my boyfriend." He angrily grabbed his phone and accepted the cal not looking at the contact info.

"Alec!" It was Simon and he sounded out of breath, how could a vampire sound out of breath?

"Simon? What is it? Anyone hurt? Is it demons?" Alec immediately started interrogating the young vampire down the phone like.

"Go-" Simon coughed and then returned to speaking. "No, but my sisters missing and I think it's that vampire that's been killing mundanes. At least, it smells like something undead has been in my house."

"Call the others I'll be right there." Alec sighed pinching the bridge of his nose, he hated to cut his day with Magnus short but if it was Izzy who went missing he'd want all the help he could get to find her. He ended the call and turned to Magnus.

"Simon's sister has gone missing, he suspects the serial vamp, I'll head over to his place to check things out. He's probably already called Luke who's filed the report so no doubt the FBI will be there making it easy for me to talk with your friend. What's his name?"

"Spencer Reid, and I'll come too, a little warlock tracking may help Steve find his sister." Magnus smiled, loving that he got to work with Alec.

"Not you're just messing his name up on purpose." Alec laughed and he slung his quiver over his shoulder.

"You know me so well my angel." Magnus laughed as he summoned a portal and the two stepped through it heading to Simon's.

There were aspects of being a detective that Luke both loved and hated. Today he was living all the scenarios he hated. A serial killer at large in his city that he could easily stop but that was most likely start a true war between his pack and the rest of the New York vampires, besides Simon who he had just gotten off the phone with. He sighed as he approached the captain's office. He knocked and opened the door once he got the come in. "Captain Vargas. We have another kidnapping." He sighed again as she looked pissed.

"Who now?" She questioned.

"Rebecca Lewis. Her brother just called, he's Clary's best friend so he called right away when he noticed she wasn't home, he knows her routine and I agree with him that this isn't her behaviour, she's in trouble and the serial killer's type, young and fit."

"I believe you Garroway, good this I already called the FBI in, start a file on her and get some officers over to the Lewis house, I'm sure some of the BAU will join you shortly after they touch down here.

"Will do captain." Luke nodded before exiting the room, wondering how in the hell the FBI was going to be able to capture a vampire on a rampage and why the hell the clave hadn't done anything about him yet. His supernatural hearing picked up the main door to the precinct. The FBI BAU team he , he stood up and made his way to great them.

"Agents." He greeted the 3 agents walking up to them. A stoic looking one with a hard face and dark hair, one with a loose fitting high quality made jacket, and a female dressed smartly with dark shoulder length hair.

"Detective" The stoic looking one nodded to him.

"Garroway" He held out his hand.

"Hotchner, and Agents Rossi and Prentiss." He referred to the two standing next to him. "I've already sent other agents to the most recent crime scene and the coroner."

"Redirect the one's heading to the corner, we just got another report of a missing person. Rebecca Lewis, 20. She's the older sister of my step-daughter's best friend. I hope that's not a problem as I intend to work this case as level headed as I can."

"No worries, one of our own agents has been taken as well so we're in the same boat as you." Agent Rossi informed him.

"Very well." Luke nodded now fearing he'd eventually have to tell them about the shadow world. Rebecca knew of it because of Simon but he hadn't gotten the chance to tell her everything about it yet, she just knew that he was a vampire and that other creatures existed, some were good, some were bad. "Follow me, we have a room set up and you can meet the captain." Agent Hotchner nodded as Luke lead the 3 agents into the heart to the precinct. Luke lead the 3 to a secluded meeting room with 3 boards already set up with victims names next to crime scene photos, a partial geography map set up with last know sightings, places of residence, and where they were found. All the victims that were dumped were usually in alleys by dumpsters and the ones that hadn't shown up yet, Luke suspected that the vampire responsible for all this was turing them for his own personal army. Probably to fight against the shadowhunters, mundanes, and the rest of the downworlders.

"This is all we have." He sighed, "There's still some files that I'm looking over at my desk but I'll bring them here and set one up for Rebecca and your missing agent."

"Jennifer Jareau." Prentiss spoke up. Luke nodded, I'll get those started, if you need anything, my desk is the closest to the stair case in the bullpen. I'm sure Captain Vargas will be here to greet you as soon as she can."

"Which is now." The captain said walking up the agents. "I sure hope that the FBI sent us more than 3 agents." She remarked seeing the 3.

"There's 8 of us in the unit, others are already at victims homes or dump scenes." Hotch informed her. "I'm SSA Hotchner, these are SSA Rossi, and SSA Prentiss." He introduced Rossi and Emily.

"Thank you so much for coming down here, I understand you've dealt with this killer before." Vargas shook their hands as introductions went around.

"We have, he kidnapped one of out team members and held him hostage for about 90 hours. We managed to find him in an abandoned warehouse, the unsub had fled. No idea why." Hotch said.

Luke frowned, if the vampire had left their teammate alive, he was most likely not alive he was probably turned, he'd have to meet him and get a whiff of his scent, but he'd have to keep a close eye on that one, this vampire was an older one. With strong Encanto skills. Could manipulate the strongest of minds.

"Luke? You okay?" The captain pulled him from his thoughts.

"After hearing that, I'm just worried for Rebecca." He told a half truth, he was beyond worried for Simon's sister, but also that if he could trust one of the FBI agents.

"We'll find her." Hotch reassured the detective, "Along with agent Jareau and all the other victims." The agent said confidently and Luke could've sworn he saw a small smile come from the agent.

"We will." He repeated confidentially.

Scarlett sat in the passenger seat pouting as Morgan drove her and Reid who was sitting in the back reading over files to the Lewis family house, which they had been rerouted too after getting a text from Hotch.

"Suck it up Scar, Morgan called driving since you drive like a maniac." Reid rolled his eyes at his friend.

"So what if I first got my license in 1946." She grumbled slouching into the leather seat of the SUV.

"And you haven't renewed it?" Morgan questioned her.

"Piece of advice, Encanto your examiner. Makes it so much easier." She grinned.

"What's Encanto?" Morgan asked.

"Vampire mind control, you're able to influence their actions and choices, like making a mundane consent for you to bite them or in Scar's case, to pass a driving test."

"To each their own." Scarlett shrugged giving Morgan a fanged grin. "It's a skill you learn over time, you don't ever have to use it if you don't want to, but I've used it to talk myself out of a lot of tickets and, at least when I was young, being arrested for being in a relationship with another woman. As a bisexual woman, it's great to see how far lgbt rights have come. She smiled fondly thinking of her wife.

"So does your girlfriend know you're a vampire, would I ever be able to tell the person I end up with what I am." Morgan asked.

"You will." Reid leaned forward and put a hand on his friends should reassuringly. "There's no rule against it, in fact it's encouraged, better than her being shocked by it and going to the media." Reid said.

"Who said they'll be a she?" Morgan smirked at Reid through the rearview mirror.

"Your gaydar needs tuning Feathers, how could you not tell he's bi as shit. He literally checks out as many men as Magnus does, maybe even more."

"Defiantly more, now that Magnus has a boyfriend." Reid replied back.

"Wow, someone to mend his hear after Camille, didn't think that would happen this quickly." She remarked.

"Why'd you call Reid feathers?" Morgan asked Scar interrupting her and Reid's conversation.

"His wings, he calls me fangs." She explained and Reid resumed the conversation with her.

"Well it has been almost 150 years since Camille, and he was full on head over heels in love with her. She crush him, completely destroy every positive emotion he had towards love."

"Magnus is the one who took you in right Pretty Boy?" Morgan asked.

"Yeah." Reid nodded, "He's like an older brother, he's the High Warlock of Brooklyn so both of us will probably be paying him a visit during this trip."

"High Warlock?" Morgan asked looking for an explanation.

"Most powerful in a given area, I'm technically the High Warlock of Toronto." Spencer shrugged, "It's really just a formality for me. Friend of mine Casandra is handling all the High Warlock duties back home. I still have the title because I am older and more powerful than her."

"You really are that powerful?" Morgan asked and Reid nodded.

"Even with diluted warlock blood I accidentally summoned a demon at the ripe age of 9, weak demon, mom killed it in an instant because it was coming after me but yeah. 9 years old and already conjuring portals to hell. That's when dad started training me in advanced magic." He smiled lightly reliving the memory of his family.

"You miss them?" Morgan asked gently.

"All the time, but mom died protecting a mundane family and dad, though it may have started out as revenge for my mother, ended up saving an entire mundane village in the process. They both died heroes, and as I do wish they could've lived longer, the life of a shadowhunter is generally a short one, and my dad was a real hot head, protecting my mother from anything and had a temper about it." He sighed

Scar reached back and took her friends hand, squeezing it in reassurance. Reid squeezed back and offered a small smile.

"So Camille?" Morgan asked trying to change the topic as he slowed when they entered a high traffic area.

"Vampire Magnus was dating in the 1830s. Completely in love with her, but she was narcissistic, and generally a horrible person, didn't believe immortals could love one another. He hasn't cared about someone that way since. He has a boyfriend now and he's starting to act like he used to back then."

"Girlfriend, then boyfriend?" Morgan questioned.

"He's bisexual, attracting to males and females, just like me" Scarlett grinned.

"And I'm pansexual, any gender, anyone." Spencer grinned.

"Wow, for 2 people who are 100 years old-"

"Not Scar." Reid interrupted earring a glare from the vampire.

"For 2 people who have been alive and lived through most of the time periods where being lgbt was criminalized. When did you know? How did you know?"

"Magnus" The two spoke at the same time.

"He's fabulous." Reid giggled lightly remember his friends eccentric style of clothing, make-up, accessories, and hair styling. Morgan laughed alone with his friends and coworkers.

"And history is much gayer than you think. Historians have just made it straighter because of heteronormativity." Scarlett rolled her eyes.

"And on that lovely note, We're finally here." Morgan said pulling into the Lewis' driveway.

"Let's catch us a serial vamp." Scarlett said unbuckling herself and opening the door. The three agents walked up to the door, as Morgan raised his hand to knock Scarlett grabbed his hand.

"Morgan no!" She nearly screamed, pulling him away from the door. "Don't touch the door." She warned him.

"What why?" He asked as Morgan stepped in front of them butting a barrier between the two and the door.

"It's marked with the Star of David." Scarlett explained, "Vampires that don't necessarily follow a religion are vulnerable to all religious symbols." She explained, that means both you and myself, Reid's the only one who won't be burned by touching the door. Reid knocked and waiting for an answer, a petit women answered.

"Yes?" She asked.

"Elaine Lewis?" Spencer asked politely.

"Yes. What can I do for you?"

"My name is Dr. Spencer Reid, I'm with the FBI." He held up his badge, "I'm here with my colleagues SSA Derek Morgan, and SSA Cassandra Barnes." He motioned to Morgan and Scarlett, mentioning her fake identity she came up with. "We're hear about Rebecca's disappearance. May we come in?"

"No need, I can tell you who took my daughter and who's been killing all those people." She said her voice suddenly becoming harsh and filled with venom.

"His name is Simon Lewis. He used to be my son." She spoke and the 3 agents shared a nervous look. A voice spoke that made all 4 heads turned towards the source.

"Mom?"

I love cliffhangers so get used to them.

I want to thank all the readers that have read up to this point. I know this is the only story in this category of crossovers and my over imaginative mind has just come up with this shit show of a story.

Saphael is a go for this I've made up my mind
Scarlett's wife will take a while to appear because I am still figuring out her character. (She doesn't even have a name yet)
And I've now decided that this will turn into an eventual Moreid fic. Sorry not sorry

My gay ass will turn this entire story into a gay paring story probably.
