Right, this is more or less just Jace trying to understand what's going on, his musings and questions. Hope you'll enjoy it :D Let me know! R&R

Declaimer: I don't own anything to do with the Mortal instruments series!

"C'mon, let's find an empty room." The three-breasted girl said, tugging at his shirt. Jace didn't make an attempt to be polite. He was staring down at the bed where Clary lay, curled up in her little panties and huge vest top. Her knees were up against her chest and her arms were wrapped around her shins. She looked so peaceful and so deeply asleep. Her eyelids flickered a few times in result to whatever dream she was having and her petal pink lips had slight smile to them. She was beautiful.

On first look, that was what Jace saw and it took a few seconds through which the three-breasted girl protested and tried to pull him with her again. But by the time she left him alone, Jace had noticed something else about Clary. Her arm had a dark mark on it, the unmistakeable mark of a rune that he knew as the rune of peace, meant to give peace to the wearer, to give to them whatever they needed which, in Clary's case, was sleep.

There were two main things surging through Jace's head, battling together as Jace thought which one was the most important right now. He decided that the reason Clary was here, at this warlock's house, asleep in his bed while she was supposed to be at that Simon's house was the most pressing question.

Jace sat slowly and carefully down on the bed next to her. She didn't stir.

How had she ended up here? Out of everywhere? Was she still able to see the "spiritual" side of the world? Did she know what Magnus was?

As none of these questions could be answered without waking her, he concentrated on the other burning question. How could she have a rune on her? The obvious was that she had shadowhunter blood, as she wasn't a forsaken, in the slightest. Her skin was rosy, her lips bright pink, her lustrous hair was just that and her behaviour – even in sleep – was that of a peaceful girl.

So she had shadowhunter blood. That answered some questions, and raised more.

How did she not know of this world – as she so obviously hadn't at the time they'd met, if she were a shadowhunter. All Jace could figure was that she'd either been brought up in ignorance because of a lie or because her mother hadn't know her father was one.

But why then, would she be so shocked to see demons the other day when they'd surrounded her house and attacked her? How hadn't she gotten used to them by now?

When Jace had first moved to New York after his father had died, he'd found it funny that people could walk around in utter ignorance, not seeing things that were so obvious to him. He'd gotten used to seeing demons and so had Isabelle and Alec and they'd grown up here, where Clary had. So why was she so scared. Even if she didn't know what they were then at the least she'd be used to seeing them or in a crazy house for seeing stuff that "weren't there" as the mundane would say, at which point the institute would have been alerted and would have come to get her…and she would have been trained…with him.

The idea of fate wouldn't exit Jace's mind until he pushed it out. He stared down at the peaceful Clary, lying there, so peaceful.

"Jace!" came a shout from the first floor where the party was still going and the music was still blaring. Through the noise of the party, Alec was searching for him. With a very exasperated sigh, Jace pulled himself to his feet and backed out of the room, staring at Clary all the while. He went to the landing and shouted to Alec "Up here." And retreated back to the room.

He sat back down on the bed and was staring down at Clary when Alec burst into the room. He looked at Clary, then at Jace, then a Clary again.

"Dude, that's the girl from the other night." He said.

"Oh." Said Jace. "Is she? Wow,"

"No need, Jace. What we need is…Holy sh**! She's marked. Did you?"

"Yes Alec, I marked her to test if she's human even though the only evidence I have against her being human is that she saw Demons minutes before they attacked her. Yes, I did."

"But Jace-"

"Cool it Alec, of course I didn't. Can't you see when I'm being sarcastic? It's not exactly subtle!"

"Yeah, well you're laying it on thick tonight, I guessed you'd be serious any minute now."

And he was. They discussed ideas and came up with…nothing. It was about the same time as Alec said "But she's marked," for the seventh time that the door swung open to reveal a tall figure in the doorway.

"Well, Well. What do we have here?" he asked and smiled widely, revealing all his sharp teeth. Alec and Jace exchanged glances. Here goes…
