"I can't believe it!" Isabelle says, sitting in a chair next to Alec and folding her arms over her chest.

"What? You broke your nail in the battle too?" Jace replies, taking a look at his nails. Isabelle rolls her eyes.

"Sebastian; he is a monster. We almost killed him, and now the Clave just sent him to the jail, or whatever. He deserves to die! And you are just being playful about it because your sweet sweet Clary is safe now."

"You're not the only one mad about it, but the Clave thinks it's for the best to keep him for now. They can get much information from him and…" Alec's voice trails off as they hear a loud noise. They exchange looks.

"Should we check it out or you want to keep right there looking at my pretty face?" Jace says and Alec and Isabelle get to their feet. The three of them run to the elevator. When they reach the first floor, Jace's face changes completely. Alec get to his side to see what Jace saw to look so worried, but he already knows, just one person can make him look like this: Clary.

There she was, but she shouldn't. She was supposed to be somewhere far away with her mother and Luke, in a family's trip. She was at the middle of the room, her face was against the floor, her red curls were a big mess and she was bleeding, completely still, laying on her stomach. Jace whispers her name and runs to reach her. He kneels beside of her, taking the hair out of her face gently and then he frowns. There was something wrong.

Clary was so small; she couldn't have grown up so much in the last two weeks. And when Jace took her in his arms, it was visible: That wasn't Clary. There were three emotions crossing Jace's face now, and he almost never showed his emotions. There you could see a clear mix of relief, confusion and curiosity.

"She is alive. We have to take her quickly to the infirmary; she has lost a lot of blood." They went to the infirmary while Jace pressed his hand on a deep cut under the girl's rib cage, trying to contain the blood. Jace placed her in one of the beds of the room, taking a look at her. The three of them looked at her in silence for a while.

"I thought…"

"You thought she was Clary, but clearly she isn't. I mean, look at her. She is taller and really hotter, with those perfect curves and big boobs." Isabelle says and Alec glares at her fiercely. Isabelle shrugs "What? She really has big boobs."

Ignoring his sister, Alec says "Well, she isn't Clary, that's for sure. But who is she? I've never seen her before. We don't know what attacked her either and we are alone until mom comes back from Idris, what should we do?"

"Call Magnus." Isabelle says and Alec sighs.

"I can't call him, we are not getting along very well, and…"

"Time to stop fighting, call him." She says again and hands him a pink phone. He takes it and calls Magnus.

Some minutes later, Magnus arrives. Jace and Izzy left the institute to the night's patrol and Alec stayed to take care of the girl.

"Doctor Magnus here, what's going on?"

"This girl, she just got stabbed, we found her on the floor bleeding, unconscious."

"Wow."

"What? Do you know her?"

"No, but she doesn't need my help."

"What do you mean?"

"You said she just got stabbed? That you found her on the floor? That is… Not possible." Magnus answers and takes a white wet cloth, one of the cloths next to the bed that were there to clean her blood as soon as he arrives. Alec didn't want to try it, he was afraid he would hurt the girl even more or something, but he took some stuff that Magnus asked thru the phone. Magnus leans over her still holding the white cloth and takes her shirt off slowly, and then she is just wearing a black bra and her jeans. He takes a curious look at the deep cut Jace was pressing before. He cleans the wound and…

"See? There is nothing here, but blood. It seems like she got stabbed months ago. It's just a scar, but the blood wasn't even dark yet. She is healed. Did you draw some rune on her skin?" Alec shakes his head.

"No, I don't know if she is a Shadowhunter. I mean, I didn't find any runes on her arms or her neck. I thought it wouldn't be a good idea to take the risk and draw some rune on her skin without knowing what she is."

"She has a rune. Look." Magnus points at a little black rune on her chest, near to her heart. A permanent rune.

"Oh, well. I wouldn't take her clothes off to look for runes, I mean, it wouldn't be…"

"Nice? Alec, the girl almost died, I guess she wouldn't mind if it could save her life."

"But normally our first runes and most of them, we draw it on our arms and wrists."

"She just has one rune. Probably she didn't know what she was until a few ago. Are you sure that this blood is hers?"

"I saw her bleeding, yes, I am sure."

"How could she heal so fast?"

"I don't know, but I know the blood was her blood."

"I can't… Feel her."

"Feel her?"

"Yes, her strength. She isn't a mundane, of that I'm sure. But she doesn't… "Feel" like a Shadowhunter either."

"But she has a rune. What else could she be?" Magnus shrugs.

"I've seen a lot of things, but this time, I have no idea."
