Hey! Sorry it took me so long to update, and it isn't as long as the last but I tried. I got lots of requests to update so thank you all so much for the support I'm so glad you liked it! So it took me a while because I had actually no idea where I was going to go from there but now I do! This chapter does have a some sizzy and malec because I really love ships, but next chapter should focus on the actual family bits. I had to flip through some of the books to refresh my memory and it took me hours just to get half as many words as last time but here it is.


Isabelle stomped down the hall to her room, her black hair bouncing off her shoulders. She half expected Alec to follow her, but he didn't. He was probably calling Magnus to laugh about how mad they made her. She couldn't believe he thought that would be funny. Telling her that she's the sister of the boy who killed her little brother? That wasn't funny. That was cruel.

Reaching her room she slammed her door shut. She desperately wanted her mother to yell at him, but she wasn't the type of mother who cared enough to ask her what was wrong. Quickly, she turned and left her room again, strutting down the hall to the guest room where her mother was staying. Angrily, she flung the door open.

Her mother looked up from the suitcase she was packing, wide-eyed.

"Isabelle, what are you-"

"Mom, you won't believe what Alec just did," Isabelle said.

Maryse raised her eyebrows.

"He thought that it would be a funny joke to tell me that I was Valentine's child. I mean what-"

Maryse cut her off.

"He what?"

"I know right! I mean-"

"He promised he wouldn't say anything."

"What?"

"What?"

"It's true?" Isabelle backs towards the door.

"Isabelle-" She stopped her mom this time.

"No. No, you have to be in on the joke. It's a joke, right? It's not funny."

"Izzy, I'm sorry."

"Mom, stop it. It's not funny."

"Isabelle," her mother put a comforting hand on her shoulder and Izzy shrugged her off.

"Don't touch me," Izzy snapped, throwing open the door of the bedroom and walking out. As she ran down the stairs, Jace, who was on his way up, grabbed her arm.

"Iz. Hey-what's wrong?"

"Leave me alone," she snapped, yanking from his grip and rushing out the doors of the institute.

She didn't know where she was going. She hadn't thought it through before she stormed out. By then she'd realized that it wasn't a joke. Her mother didn't joke. She wasn't that kind of mom. It wasn't until she looked up to see the white house she was standing in front of that she realized she was at Simon's house.

Everyone had told him he could stay at the institute while they helped him prepare to ascend, but he had declined, saying that if his mother had hated him for being a vampire he was glad he got a second chance. In a way, Simon thought that demon had helped him. They still talked now and then, Simon and Isabelle. They'd gone on a few dates here and there, but he still didn't remember. Not completely. She hoped it'd be different once he ascended.

Hesitantly she rang the doorbell. It may have been a bad idea, it was late and Simon's mother was probably home. After a minute or so of waiting, the door swung open revealing Simon. He was wearing flannel pajama pants and a Star Wars T-shirt.

"Iz? What are you doing here?"

Isabelle opened her mouth to speak, but Simon rambled on.

"Not that it isn't okay for you to be here. Of course it's okay. I just wasn't expecting you."

Isabelle wants to laugh at him, but she can't bring herself to.

"I was in the neighborhood. Thought I'd stop by, if that's okay," Isabelle said, raising an eyebrow.

"Of course it's okay," Simon said, still standing in the doorway.

"Are you going to let me in?"

Simon widened his eyes. "Right. Right, yeah. Come in." he opened the door wider allowing her inside.

"My mom's at work," he explained as Isabelle eyed the empty pizza boxes on the counter.

"I could have cooked for you," she said.

Simon snorted and she shot him a glare.

"So, why are you out so late?" he asked.

She looked at him, his glasses were crooked on his face and the way he looked with the tip of his tongue sticking out of the corner of his lips made her want to laugh. Or cry.

"I ran away," she said calmly, hopping up onto one of the bar stools.

"What? Why?"

"Because my family is full of filthy liars."

Simon looked at her worriedly. He'd never heard her say a single bad thing about her family. That he could remember, anyway.

"What happened?" he asked.

She turned to look at him for a moment. Well, she planned to only look for a moment but it turned into a full on stare.

"Iz?"

She swallowed. "They told me...they told me that my dad isn't actually my dad."

He furrowed his eyebrows. "What do you mean? If he's not your dad then who is?"

She stares at him again, shutting her eyes and taking a shaky breath before saying,

"Valentine."

Alec turned his key in the loft door again. It was late and Magnus was probably worried.

When he opened the door, the apartment was dark except for some fashion show on the TV. Magnus was asleep on the sofa, Chairman Meow asleep under his arm. Alec shut and locked the door. He walked across the room and crouched down beside it.

"Magnus," he whispered, gently shaking him.

"Magnus," he said louder.

Magnus woke with a start, shoving Chairman off the couch.

He looked around for a moment before his eyes landed on Alec.

"Alec. You're home. Where were you? It's late."

"I was right," was all Alec said.

"Right about what?"

"Izzy. She didn't believe me but I heard her talking to Mom and I think she ran out. She hates me."

Magnus sat up, pulling Alec onto the couch with him and wrapping his arms around him.

"She'll come around," he said.

"You think so? I don't even know if she'll come home. She sounded really upset."

"Of course she's upset. Did you expect anything else?"

"I guess not."

"Are you alright?" Magnus asked.

Alec nodded slowly. "I left before Mom could get mad at me for telling Isabelle. Jace doesn't know anything yet. I don't know if I should tell him, he's been stressed out enough with learning to run the institute."

Magnus rubbed his back comfortingly.

"When Isabelle comes around maybe you can decide together."

"If she comes around."

"She will," Magnus assured.

"How can you be so sure?"

"Because she's your sister."

"Only half," Alec said.

Magnus leaned forward to look him in the eyes.

"And Jace is only your cousin, but you and Isabelle treat him as a sibling. It makes no difference. You grew up together. You have the same mother. She's your sister."
