A/n: Three years ago I wrote this and just now found it in an old notebook in my room. It's post City of Glass as imagined by moi if Clary continued her training.

Liaisons Dangereuses

"Left Clary, to your left!" she ducked right, rolling under the conveyor belt and returning upright on the other side. She whipped her knives (Azrael and Veahavtah) as hard as she could at the baby selkai demons. They were eight feet tall and had rather sharp and poisonous looking stingers for noses. She got one in the shoulder and one right between the eyes.

"Jace! I got one!" She suddenly realized the abandoned factory on 113th street was not the place for a victory dance and rightly so. She restrained herself to silent self-congratulations.

"Mazel tov," her boyfriend quipped from across the room where he was fending off the mother selkai.

"Don't be snarky," she scolded, placing her hands on her hips.

"M'not!" he grunted under the weight of her giant preying mantis-like blade of an arm. "Just busy!" he shoved the mother off and tossed holy water in its face, buying a few seconds. "Toss me a knife sweetheart?"

She rolled her eyes and did. She liked that she didn't have to worry about poking out his eyes or turning his brain into a pincushion because of her aim anymore. It was kind of nice. Enariel didn't have as much effect as they'd hoped.

"Oh for fuck's sake," seemingly from nowhere he pulled out a staff about a foot long with a curved knife attached to the end, he jerked it and the staff seemed to fold out until it was as tall as he was.

He used it to pole vault over the mother selkai and stab it in the back with the runed blade.

"You have to teach me how to use that."

Jace sighed, "Don't you just love when demons invite themselves to date night? I think it's sort of rude personally." He smirked and came over to her, using the naginata as a walking stick. He'd twisted his ankle (gracefully) on his landing. "Although I have to say; it's very hot that you carry that many knives with you."

"Mom!"

"I'm just saying," Jocelyn let the sentence trail off into nothing as a delicate blush bloomed on her cheeks. "You act like I'm the bad guy because I won't let you sleep at your boyfriend's house."

"It's the institute, it's not the same thing! It's not a big deal and I'm tireeeed." Clary whined into the receiver.

"Because Maryse is going to chaperone? You might as well have gone to some seedy hotel in Jersey!"

Clary laughed, "We'll be sure to keep the hanky panky to a minimum, okay?"

"Clary, come home right now."

"But there's a bed right here."

"Now."

"I am lying down in bed now and going to sleep. Goodnight mom."

"Clary!"

Jocelyn slammed down the phone and sulked into her tea and chinese takeout. Luke squeezed her shoulder comfortingly. "Trust Clary," he said, trying to soothe her, "She's a good girl." This did not soothe her.

At all.

"What?" mumbled a sleepy voice.

"If you touch her I'll cut your nuts off."
