Chapter 9- Filling

(Third person)

It has been months since anything exciting has happened. Jace and Clary finally got word that their family knew exactly where Valentine and Jonathon was. They just had to wait for the group plan, as everyone had to be part of it. Simon, Izzy, Jocelyn, Luke, Jordan, Maya, Alec, Magnus, Jace, Clary, and a few other werewolves part of Luke's pack. Valentine and Jordan was in New York, oddly enough in the last place anyone may look, a church. Though the demons and every other evil Downworlders that dare cross the Clave- which was few.

The part of the plan THEY knew was that they would attack at the end of the month. They would come to Magnus's safe house where Jace and Clary were located and plan the events out. Simon, Derek, Chloe, Tori, Jake, and Kit would not be part of this. They didn't want to risk any of their lives for something that they weren't part of. Well according to Jace and Clary, who didn't want them anywhere near them as the group had become close with each other.

Chloe and Derek, sleep together almost every night. Only Jace and Clary knew this, as they helped them hide it. Chloe and Derek haven't done anything, Chloe just wants her nightmares to end, Derek was the only one who made them disappear because she felt safe with him. Derek didn't mind, the werewolf in him wanted her next to him ALWAYS. Jace and Clary would wake them up early before anyone else woke so that Chloe could go back to her bedroom. But it usually ended up with the four of them training.

Jake knew this though. He knew the relationship between Derek and Chloe. It bugged the crap out of him. He didn't understand why it did, he was protective over Chloe, like a brotherly protective. Jake was adopted he knew that much. He also knew his mother was the necromancer, pretty much like Chloe's. The longer he was in the house, the more he started questioning. He and Clary look a lot a like. The blue eyes, his hair that is originally blonde, the fact that were born the same day- but only he knew that. Chloe hadn't questioned anything of why they were so alike.

Though, he knew if she questioned enough about him, she would know. He was excited to learn he had found his sister. Once his adopted parents told him he was in fact adopted they helped him find what city he had come from, what hospital he was born at, how many babies were born that day, and put them all together to realized he had a sister. But he wasn't for sure has the last name of the woman wasn't given. His family had went through all medical records and all of them still had there children and the unnamed woman was the only woman that day who gave a baby up for adoption.

He wanted to know why she gave him up, but kept Chloe. But seeing her and hearing her story, and added it to what his adopted-supernatural- parents told him about. It was to protect him, Separating the two children to protect them. They were powerful and having them together could cause real damaged. Which was one of the reasons why he hasn't told anyone that they were related. A DNA test would prove it, he just had to convince everyone that it could be possible. He wanted to tell her and them, because if they're on this side of the war, they could help. They alone would be able to make everything stop. Alone they were powerful, working together… they'll be unstoppable, which would most likely cause everyone to fear them. He didn't want that for Chloe though.

He wanted to protect her, once he put everything together. What he wanted to happen, happened. He wanted to go on with his plan to help destroy the reason his parents gave him up. He wanted to destroy the people that cause his family the split. But seeing Chloe… he couldn't and wouldn't do that. But he knew he had to tell her they were related…

Simon had watched Jake from the first time he came to the house. At first he put it off as just being protective over some one new. But the longer Jake was there, the more he noticed things about him. How Jake studied Chloe all the time, the different looks he got when Tori flirted with him as he was unaffected by the effort. The way Jake moved, talked, worked out. When Simon had his first sexual thought about Jake he freaked him out.

Simon was not gay. No. He liked girls…Women. Simon couldn't be gay. But then it would explain the need to be with a girl but not like them at all in any sort of way which would be why he would break up with them. Simon thought at first it was because they weren't worth anything. They wouldn't be able to make him happy in any sort of ways. But just talking to Jake or being in the same room as him made Simon nervous, but the good nervous. Simon had given up trying NOT to think about Jake in the sexual way as they would always surface every so often.

He wasn't going to tell anyone. He didn't even know what was up with him. He knew being gay was nothing wrong about it. He actually supported it, because you couldn't help who you fell in love with. He just wanted to make sure, that that was it. He was really gay, or that this wasn't some messed up thing in his head because we had no one to flirt with. Tori was his sister, Chloe was with Derek, Clary was with Jace. After a while he knew he was just trying to convence himself that he wasn't gay or at least wasn't attracted to Jake.

He wasn't even sure if Jake was gay. Jake had never given Simon a reason to think that. Jake was a too himself person, rarely spoke about his family or his past life before showing up at the safe house. The only thing he had given was that he didn't flirt back with Tori, but that could've been because Tori wasn't his type of girl or…just wasn't his type of sex.

Tori didn't get why Jake wasn't flirting back. Tori didn't understand what was wrong with her. She had flirted with Jace, who flirted back but wouldn't go further than that because he was with Clary. She would NEVER flirt with Derek and even though she had flirted with Simon, before she knew they were related discussed her even until today. Which left Jake, who just plan didn't do anything to stop her from flirting with him or just flirted back.

He just kept his mouth shut, and it seemed like he ignored her as much as possible. She had noticed him every once in a while he would watch Chloe and Derek, mainly Chloe. But then Simon would be watching Jake, which confused her slightly. Because Simon wasn't watching Jake like Jake was watching Chloe and Derek. Jake was clearly curious with his watching. Simon had started off curious with a protective look, but it turned into an awe struck look. Confusing her to no end. Simon was a bit of a man whore, so why he seemed awe struck she hadn't figured that out yet. She just knew something was going on with the people in this house.

Everyone started keeping secrets, Jace and Clary hadn't said much since a month or so ago when they heard from their people. Derek and Chloe… she didn't know what but something was up with them as well, they seemed closer than ever. Then the Jake and Simon thing about watching people and that Jake wasn't flirting with her. Tori felt lost, completely lost, but wouldn't say anything because that might open up a whole new can of crap she didn't need at the moment.

Kit knew something was up with the kids and wanted to talk. As he made sure he had enough chairs for everyone to sit in he called them down. It took a couple moments but everyone finally showed up.

"Take a seat." He leaned on the lone table in the middle of the room, the chairs had formed a semi-circle with the attention on him. The kids waited for the problem Kit had called him down to talk about.

"What is going on? I know it's something, each of you have been uncharacterically quiet lately." When no one spoke up, he asked again but more demanding leaving no room to question why he wanted to know. Kit hated being this way, but he knew that it was the only way to get questions out of the kids at the moment.

"Lets start with Jace and Clary, then." Kit crossed his arms over his chest, waiting for them to answer. Jace and Clary hadn't told anyone about the plans even that everyone was coming over. After a moment, Clary spoke up.

"Our family has found my father and brother. They're planning on catching them, with the help of Jace and I. I don't know when they'll be here, but they're coming here to help plan because it is safer here than anywhere else." Kit nods.

"How many? Will there be enough room for them?"

"My mom, step-dad, Vamp. Simon, His girlfriend- Izzy, Alec, Magnus, Werewolf-Jordan, Werewolf-Maya, and a few other werewolves from Luke's pack. It's most likely pairing up. Jordan and Maya are in a relationship so they'll share a room, Izzy and Simon are in a relationship so one room, Alec and Magnus share, and my parents. But we'll have to pair up here. Simon and Jake, Derek and Chloe, Tori and a werewolf, Jace and I… that should be enough room for everyone." Kit nods again, not questioning as to why they put Derek and Chloe together as it seemed everyone was pairing with their boyfriend and girlfriend. Plus he knew how hard it was to stay away from the mate, which he had concerns about that Chloe and Derek have been sharing a room already.

"And you two?" He turned to Derek and Chloe, half way knowing the problem but wanted to be sure. Chloe wasn't looking at Kit, but he could see the red hue on her cheeks along with Derek's. He can see Jace smirking at the two which just further Kit's question and that was all he needed.

"I see." Kit said keeping his face neutral. Kit didn't mind at all, he knew it was a matter of time before they started sharing a bed. He didn't like that they were still young, but that comes with finding your mate at a young age. "Just don't let anything happen." Kit further explained to the two, he can see Jake, Simon, and Tori confused but wouldn't bring it up in front of him about what was up.

"Jake, may I ask what is up with you?" Kit had used a nicer tone with him. Knowing he didn't have any control over Jake that much. Jake shrugged and looked at Chloe. Jake is taking this chance to tell Chloe but he was slight nervous. Taking a deep breath he started.

"I was adopted shortly after I was born. I was born in Buffalo, New York to an unnamed woman. On August 25, 1995." Chloe turned to look at Jake, shocked mostly because she didn't know they were THAT close in age. Chloe was born in Buffalo, but moved around a lot only to end up back in Buffalo at the age of 15 her home town as her father called it once. Jake continued.

"When my adopted parents told I was adopted, they help me find my birth parents. Which led us to a hospital that I was born at and we learned five babies were born that day. Only one gave up a baby for adoption, turns out the woman had two babies. A girl… and of course me. We did more research- by the supernatural terms- the woman was a Supernatural married to a human man. You see, when a Supernatural gives birth, they usually have a Supernatural doctor just in case the baby uses its powers at the early age without realizing it. She was the only Supernatural in that building…" Jake turns to Chloe and watches her. Chloe hadn't fully put it together, but there was only one hospital in Buffalo. Her parents- one human, one Supernatural. His birth mother the Supernatural…

"Are you trying to tell me. That you're my twin brother?" Jake had nod and turned to Kit.

"I'll take a DNA test to prove it. But after that I had given up on trying to find the family, it was a guarded secret. Having me and Chloe using our powers together… as one… we can be very powerful more than we are now. Being on the wrong side of the war can cause serious damage. I didn't want to tell you, Chloe. To keep you safe, mother split us up to keep us safe. I know that by the amount of research I did. We have to keep this secret. No one can know about it."

"Why didn't dad tell me I have a brother?" Chloe further questioned.

"Mom could've only told him about you. He could've known and she told him I died in thw whom… I have no idea Clary." Jake said. Kit turns to Simon, waiting for him to explain.

"Nothing really. Just watching everyone." Kit took that as an answer because Kit had seen him watching… mainly Jake like he didn't trust him. Finally Kit turned to Tori.

"Pretty much the same like Simon. Just watching." He took that as an answer because he was mainly worried about Jace, Clary, Derek, Chloe, and Jake. Simon and Tori hadn't given him a reason to be concerned about them, though he knew something was up with both of them he knew it wasn't as big as the other five. Kit let them go finish whatever they were doing and thought about what the five had said.

He wasn't worried about Jace and Clary, seeing them trainging the kids he knew they would take care of themselves. He was worried about Derek and Chloe but that was out of fatherly concern on them sharing a bed. He worried about Jake, know because of what he had said about being Chloe's sister and them being extremely powerful if working together. He also worried about the extra people that would be showing up soon…
