Who am I - Who are we?

Pandemonium

On his way to the Pandemonium Jace called Alec asking him for his second sword.
"Why? Where have you been Jace? You know this mission is important I don't want you to get hurt!" Alec answered his request.
"I have been busy and trust me I am more than relaxed and ready to hunt this bloodsucker... and maybe we have to skip Takis for a bit" he added.
"Takis? Why Takis?"
"Well...."
"Jace don't tell me you screwed the girl that works at Takis"
Instead of answering that question Jace mumbeled a see ya soon and hung up on Alec.  He loved his Parabatai but was in no mood to explain his sex life to Alec on the phone.

He would have been faster with a cab but he didn't have any money with him so he glamoured himself, ran down to the subway and hopped over the barrier to catch the approaching red line. Jace hated the subway. There were just too many people in New York that were taking the subway and he was glad to be glamoured especially as he overheard two people talking about the Pandemonium. Mundanes he thought. No chance any of the  mundanes would even go to the Pandemonium if they could see through the glamour. The Vampires alone would make them wanna leave screaming their lungs out but also some warlocks have pretty special marks that even gave him goosebumps sometimes.

Squeezing by those two people to get of the train a small but intense shockwave hit him where he touched the boys arm sucking all air out of his lungs leaving him with a spinning head.
"Ahh" the boy screamed rubbing his arm.
"Simon what's wrong" the girl asked. Confused Jace stumbled out catching his breath. That was a weird experience right now. What was that? It felt like an electrical shockwave hit him and made its way all they way up to his heart.

After his breathing was somewhat normal again he ran up the stairs taking two steps at once only to realize he got out one exit to early. The street he was running down to get to the Pandemonium was a dark ally known for underworld activity so all kinds of shady creatures were lurking from the rooftops. As soon as they saw his seraph blade though they disappeared into the night. There was no time for Jace to go after them and get them all even if he wanted to but he was already late to meet Alec and Izzy at the entrance.

Turning the next corner he already saw his siblings leaning against the wall next to the entrance. Alecs black hair was curly and hung loosely from his head. Izzy has the same hair colour but she put her hair up in a high braid that reached all the way down to the middle of her backless red dress. Jace would probably nerver understand why his sister would wear those kinds of dresses and especially 5 inch heals to hunt demons. Him and Alec alway wear fighting gear, his being green today and Alec being dressed in the same outfit colored black.

Preparing himself for the battle he bumped into a red haired girl waiting at the entrance.
"He watch were you are going", she said.
Jace turned around with a surprised face.
"You can see me?"
"That's kind of the point isn't it. But you obviously didn't see me", she shot back at him.
Looking down at Clary Jace almost got lost in her green eyes. A shiver went down his spine. It was almost like she could see straight to his soul. Alec shouting his name broke the intense eye staring between the two of them.
