Clary

Demon-hunting was so troublesome, sometimes. Othertimes, it was kick-ass and adrenaline-jumping. And a pain to clean up after, Clary thought. She missed the days when she could relax and simply sketch whatever beautiful thing came to mind. Now her days were filled with demon-hunting, training, and tension.

"Clary," Jace came and swung his arm over her shoulders with a kiss. "Has anyone ever told you how sexy you look when you fight?"

"Yes. You, every time we go out on a hunt," Clary laughs and punches his arm.

"Because it's true, Clary," Jace smiles. "You get this gleam in your eye just before you deal the finishing blow, and your hair sparks like fire, and your body twists and turns with even more grace than a pixie." Jace's arm slid off her shoulder to her waits, hugging her closer to him.

"Liar," Clary muttered. She had just as much grace as an elephant in a glass garden, but she blushed all the same. Just then, the ground behind the hunter split open, and an unearthly fiery light streamed through a portal. Jace instinctively drew his blades and pushed Clary behind him. While it was adorable, Clary was also slightly annoyed Jace thought she needed protecting. Then again, Jace was a better hunter than her and it wouldn't hurt to have him take on the surprise attack.

A beam of light shot at Jace. "Get back!" he shouted and shoved Clary hard to the side. The light followed the golden-haired boy and instead of deflecting off his seraph blade, struck him hard and threw him against a brick wall.

"Jace!" He didn't move, and he didn't groan.

Clary turned back to the portal, shadowhunting training finally taking over. She'd wreak havoc upon the next creature to climb out of that portal, and hopefully Izzy and Alec would realize something was wrong and come to look for them.

"Ariel," she said, and her seraph blade glistened in the moonlight.

A human hand waved up through the portal. "Help!" it screamed in a deep, gravelly voice. It sounded like it was resonating from the deepest parts of the earth, but there was also a hint of human desperation. "Help! Don't attack!" The voice said again, another hand joining the other as the creature pulled itself out of the portal.

Clary paused. There was the outlandish possibility that it was a mundane dabbling in magic who managed to get himself sucked into the demon world. She watched the voice climb out. And she was shocked to see someone she recognized.

"Jonathan?"

"Sisters," her brother gasped. "Sisters!" he tried to swing his legs above ground, but something caught a hold of his feet and dragged him down again. "No!"

The portal closed. A heaving pressure grew behind Clary's eyes, an insistent push and Clary tried to suppress. It hurt so, so much. Clary fell to darkness, and then she saw the pictures.

Kaitlyn

"NO!" Kaitlyn Fairchild shot up from her bed, escaping a horrific nightmare. It couldn't be a vision, nothing that unearthly existed on this plane. Yet, it didn't feel like a dream; the details were too vivid, and the entire experience was just as short as a vision.

"Kait?" Gabriel's sleepy voice murmured in her ear. "What's wrong?" Gabriel sat up and wrapped an arm around his girlfriend as he fisted his other hand to rub at his eyes. "Kait?" he asked again when she didn't respond. He touched her arm, and it was ice-cold.

Kait was frozen on the bed, staring unblinkingly at the wall. It was like a dam had been broken in her mind. A flood of memories invaded Kait's senses: sights and smells of a city she'd never seen, a woman she vaguely recognized, and a green-eyed flame-haired girl, a girl with the same shade of red, the same pale skin, and the same unearthly glow of knowledge around her.

"I...I can't believe it," Kaitlyn whispered.

"Kait, Kait, talk to me. What's wrong?" Gabriel was fully awake now and deeply concerned. Kait was unshakable, and even when she was shocked, she hid it well. To be openly scared like this was too out-of-character for her. Her mind was blocked, too. He couldn't penetrate the fortress surrounding it. While Kait had gotten good at shielding, it had never been this strong before.

"I have...to go. I have...to go back. I need to go back, I can't believe I left," Kait muttered.

"What are you talking about? Do I need to call Rob and the others here?" Gabriel asked.

"I left her, Gabriel. We'd never been apart, and then I left her!" Kait cried, breaking out of her rigid posture. She hugged Gabriel tightly.

Gabriel rocked her in his arms, patting her hair and kissing her forehead. "It's alright, it's alright," he said. "Who did you leave?"

"My sister. My twin sister."

Imagine my surprise when I realized no one had written a crossover for Kaitlyn and Clary Fairchild! Now my dreams have been fulfilled.
