So, before I start to explain, I feel the need to say that this is the first time I've done this, so if something about the grammar is off or something, just, get over it, please. I'm not even going to attempt to say I'm a good writer or anything because of everything I've ever dreamed of writing was not one of them, but admittedly, this plot bunny has always been there, ever since I finished reading Clockwork Angel and I've just never had the confidence or the time on my hands to write. Now, I do, and I am proud of it, I really am, it's the first thing I've forced myself to sit down and write, just to get out of my head and I finally did it. Now, I do have some scenes I thought of that I didn't include, but overall I really like this and I want you reader, (if you're crazy enough to bore yourself with this) to know that you can use this. Whoever you are, because honestly, I want someone to finish this story. If you like it, you can take the idea, the sentences, the words, and you can incorporate it into your story whatever you may be writing. If someone did finish this for me, it would mean the world. Oh, and if you do decide to make me super super happy and finish this, I hope you focus it on main characters, but please don't take it up with Jace, Clary, Will, and Jem (not so much Jem but he's still a little over written.) Please, I remember reading the first full Infernal Devices/Mortal Instruments crossover that an author finally decided to finish and she excluded characters that I loved. Isabelle, Alec, Simon, Magnus, Gabriel, Gideon, Sophie, etc. These characters have so much capable plot to them, please don't overdo the already so overdone characters. Now, away from crazy town where someone would actually care about my writing. I tried to write like a 19th century literary freak at the beginning when in Tessa's point of view but I stopped when I got to regular speaking 21st century characters. Anyways, I hope you enjoy. Leave a review, either telling me to never write again, or if you like it (really?) just tell me that. (Maybe, yes, ok?)

Tessa could go on to say Will was an insufferable, horrid man but saying so would waste breath Tessa hardly thought he was worth. As such, she only glared at him in utter disgust before returning to her toast and butter.

Perhaps it was because of what he'd said up in the attic, or maybe it was his sheer attitude, but she couldn't even find herself able to look at him for more than a moment in fear of exploding and telling him all she thought of him and saying so would be terribly unladylike.

Jessamine seemed more intent on ignoring him also as she rolled her eyes and began to play with her food.

Jem, however, seemed determined to remove the awkward atmosphere and began a conversation about the only thing either of them cared about, or 2 of them rather, but it wasn't as if Jessamine was a particularly nice chat.

Mortmain was the only thing on their minds and as they talked they agreed that maybe it best to find where his creatures were before they reached him. It would be much safer that way.

"I'll more than likely be the one to find them." Will said, and Tessa could feel her rage and annoyance seep back in.

"The only thing you'll be looking after is a better attitude adjustment." She snapped, unable to stop herself but immediately regretting her words.

He looked at her, stunned surprise crossing his face before it went back to his usual cold look. He said nothing as he looked back down at his plate and began to pile eggs onto it.

The atmosphere returned and even Jem sat quietly, unsure of what to do.

At that moment the bell rung and Jem, Will and Tessa jumped up quickly to hurry away. Staring at each other, they turned towards the door, and were joined by Sophie who looked at them strangely, before sighing when she was given no explanation as to why they were following her.

The door was reached by all four of them and there standing was a shocking party. 3 boys as well as 2 girls all dressed in appalling attire. The men wore a peculiar type of material for pants and the redheaded girl was also wearing them, as well as a loose-fitting shirt that read,

"MADE IN BROOKLYN"

Tessa couldn't help but stare at it, wondering if this girl really was from home and if so then why the shirt misspelled Brooklyn. Surely those who lived there would know how to spell it. Looking back at Will and Jem however they didn't seem to notice the shirt or its grammatical error, Will staring at something and Jem trying obviously hard to avert his eyes. Turning to see what the commotion was about she couldn't help but gasp as she looked at the girl to the far right, wearing the shortest dress she'd ever seen. A bit higher than her knees, it was white and well-fitting with a small black belt in the middle. It gave off her body shape perfectly as the dress looked like it'd been painted on, and Tessa couldn't help but feel more than a little jealous at the way the boys were reacting or for Jem's sake, trying hard not to react. She wore shoes that seemed to have something attached to them to make them higher. And her hair was held back by braided strands following the back. Tessa couldn't help but wonder how it looked in the back. Her thoughts were cut short by a snapping,

"Stop, looking at my sister you perverts."

She looked back at the three boys on the steps, unable to believe she'd missed the resemblance of one of them to their very own Will Herondale. Looking back at the boys inside, she could see they were taken aback, by one of the boy's resemblance that they'd somehow all missed or by the blond boy's words. Tessa guessed both. The boy with the startling features however looked back at Will, his jaw set and his hands in fists and the one with the blond hair seemed ready to fight if the occasion led to it. The other boy, who Tessa could've sworn was next to the two boys last she'd seen him was now next to the beautiful (though it pained Tessa to admit) girl, his arm wrapped around her possessively. She looked annoyed as she glared at him, but Tessa couldn't help but notice the underlying tone of affection in her eyes.

"Perhaps, if your sister had better appropriately dressed herself-"

Will began but was immediately cut off by,

"I'm so sorry for the inconvenience, but my friend isn't in the best mood this morning."

All three boys looked at Jem,

"I'm sorry for us showing up unannounced, but please may we speak to the head of the Institute." The boy did seem much more well-mannered than Will, which was shocking considering they looked so alike.

"You are?" Will retorted.

The boy looked back at him and Tessa could've sworn she saw sadistic rage fill his eyes.

"My name is Alexander, and that is my sister, Isabelle." He said looking to the girl who still had an arm around her.

"My brother, Jonathan" he said nodding towards the blond one, "and she is Clarissa," he said addressing the redhead, "and our friend, Simon." Lastly looking towards the boy to the far right, before the blond named Jonathon who interrupted,

"And that is all you need to know. We are shadowhunters and conferring to the accords would mean that we have rights to visit any Institute in the world, and are welcome as long as we need, now, we would like to see the head of the Institute. Preferably out here thank you."

Tessa couldn't help but feel a glimmer of hope as her eye caught the girl- Clarissa's- shirt and heard his American accent. She opened her mouth to as when Sophie, who Tessa had admittedly, forgotten was even there, gasped and said,

"Mrs. Charlotte? Out here?"

"If it's her Institute she's been out here enough times." Jonathon, Tessa remembered, said.

Sophie looked amazed,

"You want a lady to introduce herself to you outside rather than in a respectable place indoors?" She said in disbelief.

He nodded, a sarcastic smile on his face while doing so. Tessa couldn't help but remember Will as he did so, and felt herself get even more confused when she looked back at Alexander who looked so much more like her obnoxious roommate.

Even more so when,

"Please, our friend is a vampire and he can't enter Institute ground."

Tessa couldn't help but notice the second he looked at Will his eyes screamed bloody murder, but when speaking to someone else, he was polite and even charismatic.

Sophie stared at his friend for a moment no doubt wondering how a vampire could be a shadowhunters friend before turning to get Charlotte, leaving them with nothing left but to stare at their strange visitors.

"Yes, alright, now William, take Mr. ah-?" Charlotte said, while looking at Simon, who answered,

"Lewis, Ma'am."

"Yes, Mr. Lewis, William will take you to a warlock named Magnus Bane and make sure he finds you a place to stay until we get things with your friends sorted."

Alexander stood straight.

"Magnus Bane?" He asked.

"Yes, Mr. Bane." Charlotte corrected herself and hurriedly added, "Don't worry for your friend, he'll be quite safe with him," when she noticed the boy's apprehension.

"Yes, quite safe," Henry said from behind Charlotte.

"I know." He said quietly, looking down at his hands.

Charlotte couldn't help but notice it, the way he said it.

I know.

As if he really did know.

There was a silence before Will stepped out and said,

"Hurry along then vampire, I haven't got all day."

"My name's Simon." He snapped as he followed.

Will didn't say anything back.

Charlotte noticed the longing in the boy, Alexa - Alec - she reminded herself, eyes as he watched Will and the vampire Simon leave.

"So please, tell me your story?" Charlotte asked once they'd settled into the library and gotten past Jessamine's screeches about how the Isabelle looked like a prostitute and Clarissa – Clary – looked like a man.

Isabelle had attempted to attack her.

Alec, having no other option but to tell them that they'd apparently gone through a case of time travel, lied.

"We come from New York. We're just visiting." He said truthfully.

"We, need help, I mean to get home."

Charlotte nodded,

"I'll write a letter immediately."

Alec froze,

"You mean like, a boat?"

Charlotte looked at him,

"Yes." She said her tone confused.

"How long will it take?"

Charlotte looked at him sadly,

"About four months."

Alec couldn't help his sigh of relief, which Charlotte narrowed her eyes at.

"I mean! We can stay here right?"

"Yes, of course." She said.

"Thank you." He smiled.

She gave him a small smile and looked around the room full of occupants. The ones of the London Institute said nothing, and neither did those of New York.

"Alright, I'll call Sophie to show you to your rooms."

"Wait." The girl named Isabelle said.

They turned to her.

"What about Simon?" She asked worriedly.

"He's with Magnus." Jem said.

"I know that but is he staying with him?" Clary piped up, clearly worried also.

"Yes." Said Will, who entered the room pushing both the double doors as he went.

They stared at him.

"I like to make an entrance."

"What did Magnus say?" Isabelle and Clary both asked in unison, ignoring his obnoxious comment.

"That he would allow your vampire friend, that may I add you're extremely attached to, to stay as long as he needs."

The two girls looked visibly relieved.

"Alright, then." Charlotte said after a moment, as she stood to call for Sophie.

"We need to see Magnus." Clary said to the rest of the group as they joined in Isabelle's room.

"He's the only one who can help with the portal."

"We'll let Simon stay there for a couple of weeks to get Magnus to trust him until we ask him to talk to him."

"A couple of weeks?" Alec asked his brother in disbelief.

"Yes. Look, I know you want to see him, but Magnus is smart and he won't just blindly help us, the only reason he did before was because of you."

Alec turned bright red,

"That's not true, I mean, sure at first, but he cares about you, all of you."

Jace smirked,

"Of course he does, who couldn't care for me?"

Exasperated, Alec sighed,

"Maybe that's why he's never said it, Jace."

Honestly, sometimes Simon wished he could punch Woolsey Scott in the face and yell,

"Hey! I'm straight!"

Because when he looked at Simon suspiciously every time he walked into a room, Simon just wanted to pull his throat out. It had been about a month since he'd come here, and he'd been given the plan, which he had, in fact, followed out. Asked Magnus, who had been wary at first but had eventually caved when he let him have a sneak peek of the future in his brain.

"Alright, I'll help, if you let me give you some advice."

Simon sighed,

"What?"

"That shadowhunter girl really likes you; you should really talk about a relationship."

And Simon couldn't help but ask,

"What about Alec?"

"What about him? Do you-?"

"What? No! God no! I mean- What did you see about him- and you?"

Magnus smirked,

"I saw him on my visit to the Institute to discuss you, and he was very good looking which means I'm bound to seduce him one way or the other in the future, and I wouldn't like to know very much about certain parts of him, I'd like to leave that to my imagination."

Simon visibly shuddered to which Magnus laughed.

Then Woolsey walked in and every single heterosexual thought he'd ever had didn't seem to matter because apparently if you get Magnus Bane to laugh, "GAY," is plastered all over your forehead.

It was horrible. He gave him dirty looks, took up all Magnus's time so they wouldn't be alone together to work on the portal, and it was getting ridiculous, so when Simon awoke to find Woolsey gone, he was beyond ecstatic.
