Title: Oh Mother

Summary: Maryse Lightwood surprises the Institute with a visit and it goes as well as you can imagine with new arrivals Clary and Simon being there. Which of course just happens to be the reason that she's here, at least in Clary's case.

Author's Note: Warning, I made the mom a not so nice person in the beginning and I'm sorry if that offends people, especially those who read the books. But please remember that this is just a fanfiction, the whole point of them is having the freedom to change things from the canon version.

Chapter 1: Welcome Mother

No One's Pov

The clashing of blades and the thud of arrows hiting various target could be heard throughout the training room. Jace and Izzy were currently dueling and Alec was of course working with his trusty bow. They all decided to get in some much needed training to pass the time while Clary took Simon out to feed. Things had gotten more hectic when they found out Simon was a vampire, at one point Alec wanted to kill him but that probably had more to do with the fact that he wasn't too fond of the former mundane. But he shut up about it when both Clary and Izzy threatened him. Speaking of Izzy and Simon they have been spending a lot of time together when they both admitted to the attraction they have towards each other, in fact they recently had begun dating, just like Clary and Jace and Alec and Magnus. Of course the only people who knew were each other, but that was all about to change.

Suddenly they all stopped and looked to each other with a knowing glance. Quickly they dropped their weapons and ran to the front entrance. And just like they thought there she was: Maryse Lightwood, Mother of Alexander and Isabelle Lightwood and honorary Mother of Jace Wayland. It had been a long time since any of them had seen her in person. All of them would occasionally video chat or call but beyong that there wasn't much contact. They figured that it must be important if she came all the way here. They pulled themselves out of their surprised dazes when she approached them and Izzy was the first to react.

"Hello Mother" She spoke us as she walked forward.

"My darling Isabelle, it's wonderful to see you" She reached towards her daughter and grabbed both of her hands and kissed her cheek. Izzy smiled at her mother and lead her back down the hall towards her brothers.

"Alexander"

"Mother" Alec grabbed her left hand in his and gives it a kiss then pulls her into a hug where she kisses his cheek also. They pull away and she turns to Jace. Jace wasn't her biological son but she loved him just as much as her other children and their relationship was just a precious.

"Hello Maryse, as usual it's lovely to see you"

"Always the charmer Jace, come here my dear" They pulled each other into a hug and this time Jace kissed her cheek. Once they were all done with their greetings they walked back to the training room and as they put away their weapons Izzy asked the question they've all been thinking ever since they laid eyes on her.

"So Mother is everything okay? You don't show up unless there's trouble"

"I'm afraid there is. We received information that you've found Valentines daughter and that she's supposedly in possession of the Mortal Cup. I've been sent here for confirmation, to question the girl and retrieve the cup by any means necessary. So where is she?" They all flinched and stared at each other nervously. But before they could answer her the sound of a door slamming and footsteps were heard. Moments later Clary and Simon ran into the room laughing and holding hands, which both Izzy and Jace would have been a tad bit jealous about if they didn't know that's how they've always been. Their happy moment was haulted when they saw Maryse. Jace cleared his throat and stepped forward for the introductions.

"Clary, Simon this is Maryse Lightwood, our Mother" Their eyes widened comically. Alec rolled his eyes, Izzy giggled and Jace remained normal on the outside but on the inside he was worried. He knew how Maryse could be and he had a feeling that they would clash with her, especially if she found out about their relationships with her kids.

After the shock wore off Clary moved forward to shake her hand with Simon close behind but still keeping his distance from the stranger. Ever since he discovered this world he wasn't very trustworthy went it came to unfamiliar faces.

"It's nice to meet you Mrs Lightwood"

Maryse grabbed the outstretched hand and shook it very slowly, like she didn't even want to be touching her at all.

"So your Valentines daughter" She said coldy as she looked Clary up and down with distate, like she was responsible for everything her father had done. Clearly uncomfortable Clary moved back to Simon, noticing that is friend was upset wrapped his arm around her shoulder and spoke up, staring her dead in the eye where he could see what she was feeling.

"She's not her father, so back off" He sounded like jagged daggers and the others took a step back, they knew just how protective they were of each other.

Maryse was taken back by his tone but stood her ground and stared at him like he was a bug that needed to be squashed.

"What is a mundane doing in the Institute?" She spoke with disgust and said mundane as if it would make her sick by just saying it outloud. Simon didn't let it phase him, he was used to it because it's how Jace and Alec acted when he first came around. Jace doesn't do it anymore but Alec is a different story, it seems his hatred for Simon grew even more after he started dating Izzy. Of course Simon had to bring up the similiarity, and we all know that Simon's big mouth has gotten him into trouble.

"Now I know where Alec gets his taste from" He said with a grimance. Suddenly he found himself pinned to a wall with her blade pressed against his neck, it burned but she didn't seem to notice. Clary tried to move forward to protect her friend but Jace pulled her back and shook his head at her, it was his way of saying it was pointless to get in her way.

"Never disrespect my son like that against or I won't hesitate to use this on you" She threatened. And like I said before, Simon's mouth gets him into more and more trouble.

"And now I know where Jace gets his violent temper from. Are you sure he's not your real son?" That was the finale straw for her and she threw him across the room into a glass wall that divided the training platform from the rest of the training room. The glass shattered on impact and this time Jace didn't stop Clary from going to her friend. She helped him up and saw that shards of glass were imbedded in him everywhere and he was bledding from a lot of the cuts. If they didn't get him cleaned up he would lose enough blood to the point where he'd have to feed again. All of them agreed that they wanted to avoid him feeding as much as possible, that usually lasted up to the point where either he would die without it or go crazy with bloodlust and tried to bite one of them.

"Come on Simon, let's get you cleaned up" Izzy moved forward and tried to pull him out of the room and away from her mother but he wasn't done yet, there was one thing he had to do.

"For the record, I'm not a mundane" He flashed his fangs and hisses at her. Once he saw the surprised slash horrified look on her face he let Izzy pull him out of the room. Maryse face quickly turned to one of angry and she let it out on the remaining people in the room.

"You let a vampire into the Institute?! I don't believe this! At least it's not as bad as you protecting the daughter of our sworn enemy! She caused all of this, I bet she dragged that boy into this. She's ruining people's lives and you are letting her! And for what? The Mortal Cup? I know you two! Why haven't you taken it from her by now?!"

Everyone stood there in silence after she finished her outburst. But the sounded was replaced when Clary walked over to Maryse and slapped her in the face. The sound bounced off the walls but was quickly replaced by Clary's angry voice.

"How dare you! Just because you're a Shadowhunter that doesn't mean you're above him. Human or vampire he is still a much better person than you from what I've seen and I've only known you five minutes. You don't know us and honestly I hope that you never do. However we will try to be civil with you since Jace and Izzy mean so much to us but if you disrespect Simon for who is he, me for who my father is or for any other reason then we will have a problem. Now I have a feeling that you're hear about Valentine and the Mortal Cup and we will deal with that later. So if you'll excuse me I'm going to check on my best friend" She left with a flourish, grabbing Jace by the front of his shirt and pulling him along with her. He looked back at his mom with a shrug and went with her, leaving Alec and his mother alone.

"What is going on here Alexander?" He walked over to her and patted her on the shoulder.

"You'll find out. Now let's get you to a room, tomorrow is going to be a long day"

As they walked to the housing all Maryse thought was just how crazy was this place ever since that girl came along? And just how much work will she have to do?
