A/N: Thanks again for the nice reviews :), I love reading them!

Lila took a swig of her water, oblivious to the absolutely shocked looks around her.

She looked up at their bemused faces, edged with disbelieve.

"What?" she said. "I knew he did something wrong. What did he do?"

She locked eyes with Jace, who was starring at her intently.

"What?"

Izzy, Clary, and Simon slowly looked from Jace, to Lila, back to Jace, and back to Lila. Clary's hand covered her mouth.

"She even looks like him," Izzy whispered, her eyes like saucers. "Look at her hair, and her nose! And her face!"

"Everything but her eyes," Clary murmured.

"Would someone like to tell me what the hell is going on?" she said loudly, disturbing people at other tables.

Simon brushed his hair out of his eyes. "They could be twins."

Lila jumped up from her seat. "If someone doesn't start explaining right now, I'm going to -"

Jace stood up across from her, interrupting Lila's threat.

"Nice to meet you," he said quietly, "I'm Jace Herondale."

Lila watched him sit back down, dawning realization spreading across her face.

"What?" she muttered. "No! I don't have any family."

"How, -" Clary started, "How old are you Lila?"

"Seventeen." Lila shot back. Jace put his face in his hands.

"Your mother," Izzy stood up, abruptly, "Who was she?"

Lila looked around, "His wife, of course. Celine."

Jace stood up and walked out of the diner. Clary gave an apologetic look to Lila, and then ran out to Jace. Izzy followed them.

That left a still confused Lila with an awkward, shell -shocked vampire.

Lila sat down, shaking. She looked at Simon, who looked as if he had no idea why he was here.

"So!" He said, tapping his hands on the table. "What a fun day this has been, right?"

Lila just looked at him, not having words to say. He smiled at her, a comforting smile, a smile that relieved tension and calmed her down.

"Simon?" she said, tentatively, "Am I Jace's... sister?"

He folded his hands together. "Actually, you're his twin sister."

She leaned back in her chair. Why would Jace lie about who his parents were? Why would they make up something like this? It didn't make sense. But by the look in Jace's eyes, it had to be true.

"I should probably go," she said, gathering up her purse and making a beeline for the back door.

"No!" exclaimed Simon, grabbing her wrist. "We have to figure this out first!"

"I don't have a family!" she hissed at Simon, "I don't need one." She pulled her wrist out of her grasp.

"Aren't you curious?" He shouted after her. "Don't you want to know about your childhood?"

She stopped dead in her tracks. She did. She really did. She wanted to know who would leave their child. Every gut instinct told her to run, to leave these crazy people and leave LA. But she needed to know.

"Fine," she whispered, turning to Simon. "I'll listen."

OoOoOoOoOoO

Clary closed the door to the hotel room, and tentatively walked to the bed where Izzy and Lila were sitting.

Jace, Clary, Simon and Izzy decided Lila would be more comfortable talking to the girls. They had begged her to come back to the hotel with them, and after a while, she gave in.

Jace and Simon down the hall, while Izzy, Clary and Lila were going to figure things out.

"So," Clary said, clearing her throat. "I'm going to explain what happened to Jace when he was born, and we're going to try and figure out where you fit in. Ok?"

Lila nodded silently.

"Ok," Clary said, trying not to scare or overwhelm Lila. "Jace was taken in by Valentine, the man who arranged the pregnancy of you and Jace."

"Valentine?" Lila whispered.

"Yes," Clary confirmed, deciding not to tell Lila that Valentine was Clary's biological father.

"Why was it arranged?" Lila asked.

This time, Izzy spoke. "He, Valentine that is, wanted to create a master race of Nephilim. So he, er, he put angel blood in your mother's womb during her pregnancy."

Lila put two and two together. "I'm part angel?" She exclaimed.

"So is Jace." Izzy said, comfortingly. Izzy moved to pat Lila's shoulder, but she Lila flinched away.

Clary's eyes lightened in realization. "That's why you could train yourself, and how you could handle Indianapolis! It gave you speed, stamina, and strength."

Lila took this surprisingly well, with only a small sigh. "Ok." She muttered, waving her hands. "But how did I get to Indy?"

Clary and Izzy exchanged looks. "We think," Izzy began, "That Valentine left you with the Penelope's to train you differently. You know, different variables in experiments."

"But there were a lot of problems going on in Valentine's personal life." Clary explained. "His wife, Jocelyn, left him. Sides were being made for a war."

"So he forgot me?" Lila asked.

"We think so." Izzy nodded. "Or, he wanted to focus on Jace, who was turning out well in tests."

Lila looked away. "Figures."

Clary saw hurt in Lila's eyes, despite everything. There was something else wrong, Lila wasn't telling them.

"What really happened, Lila?" Clary asked. "When you were ten? We know you didn't go to a boarding school."

Lila's eyes flashed with memories and pain. After a few moments, she sighed.

"It's not a pleasant story."

"We can manage."

Lila looked into Clary's emerald green eyes. Trusting, caring eyes. Isabelle looked so genuinely concerned, Lila decided to talk.

"When I was ten," she began, her voice shaking. "The Penelope's were completely and totally broke. They had nothing, but the empty halls of the Institute."

"Like I said before, they didn't care about me. I was, like a task they had to complete. I understand why I was now." She looked away, but kept talking. "They had lost everything, and they were tired of me. So, I was sold."

"Sold?" Izzy interjected. "To what, like a circus?"

Lila's eyes were heavy when they meet with Isabelle's. "No," she whispered. "Like an underground slave trade."

Clary's eyes were huge as she listened. Lila was only ten then. How could they? What kind of monsters were out there?

"I was ten," Lila continued firmly. "I didn't know what sex was." She gave a short, dark laugh. "I learned quickly."

Isabelle let out an involuntary cry. Her hands clasped over her mouth as she looked away, embarrassed.

"That took up four years of my life."

Four years? Clary thought, dying a little with every word Lila said.

"But one night, our pimp was out." Lila said, slowly smiling. "I got out through the back door. I was fourteen. And I faced a really big world."

All Clary wanted was Jace. Jace, to wrap his arms around Clary and tell her everything was ok. Clary knew this was selfish. Lila should be comforted, not her.

"I went back to the only place I knew. The Institute." Lila coughed, and shook her head. "I trained vigorously and became a Shadow Hunter. But I was scared. I was alone, and young."

Clary looked at Izzy. She was hanging on to every word Lila said.

"When I was almost sixteen, I meet a boy," Lila said quietly. "Peter."

"He was everything I thought I needed. Someone to be with. Someone who loved me. Someone I could trust." She closed her eyes. "I was wrong."

"He was all I knew, so it took me awhile to figure out he was taking advantage of me." She looked up at Clary. "I didn't know relationships were supposed to be what you and Jace have. All I knew was that he wasn't hitting me, like the men at the Trade."

"But he used me. He didn't love me. Not really. I thought he did, because what he gave was the closest thing to love I had ever encountered. And I loved him. So he used me for sex."

"I found out," Lila's voice broke, "But I stayed. I stayed with him, he who was internally hurting me. I couldn't be alone."

"Finally, I got the courage to leave him, in the middle of the night. He didn't know where the Institute was, and it didn't matter, because it was hidden by Glamour."

Clary looked right into her eyes, and saw pain, heartbreak, and lost hope.

"That's when I decided that being alone was best." Lila finished, falling against the pillows.

Clary pulled out the strongest voice she could. "Please, stay here tonight. You can borrow some of my pajamas. Don't go."

Lila hesitatingly nodded. Clary smiled, then left the room.

She sat down on against the wall, shoved her head into her knees, and began to cry silent tears for Lila.
