Isabelle reacted almost instantly, lashing out with her whip. It sliced down the monster's back cleanly, and blood poured from the wound.

"Aahh!" cried out the monster, more in disgust and surprise then pain. Then it turned and sprang at her. Luckily it flew unnaturally high and Isabelle ducked, raising her seraph blade above her head and slicing its stomach open. When it landed it rolled onto its back, and it's head rotated a full 180°.

"Hah." it laughed, "You really think that you can kill me?"

Mayrse walked over to the snake.

"Yes. I think I can kill you rather easily." she said. Then she flung her seraph blade at the darkened window.

Sammael leaped and managed to hit the blade so that it landed deep in the wall.

Clary, who had been been standing mutely while all this happened, sprung into action. She ran over to window and was about to break it when when Sammael, snaking in between people's legs with an ungodly speed, and sank his fangs deep into Jace's leg. Jace cried out in pain then dropped to the ground, unconscious. Sammael then slithered on to his chest poised to strike.

"No!" screamed Clary, "Sammael don't!"

"Why not?" asked Sammael, "Do you really care about him that much? Do you really? If you break that window Clarissa I will kill him. But if you don't you can have him. You can have your whole family. You can have everyone you care about. But do they matter that much to you Clarissa? Will you sacrifice your love for a whole world of people? A whole world? Would you really?"

Clary trembled; she began to pull the blade away from the window.

"You can't." she said.

"He was right you know," said Sammael, as if she hadn't spoken, "All you ever care about is yourself Clarissa. You've never even thought about what your doing affects other people. Jace could have died at Dumont. You knew that."

"Stop." said Clary, "Just stop."

"You'll never care Clarissa. You could have killed so many people. Your just a burden. They hate you, they hate you. They do, you know it."

Clary turned to her friends to find them all leering at her. She shook her head, trying to clear it of Sammael's tricks.

"Stop. Stop. Get out. Get out of my head. Get-" she said, but was cut off.

"Oh, Clary you could have done so much harm look at them. They want you dead. They would be happier with you dead. They're right, Clarissa, you don't deserve to live. You d-"

"I said OUT!" She roared. "OUT. NOW. I DONT WANT YOU IN MY HEAD. I AM NOT YOUR TOY!" she screamed, she could see her friends for real now, they where pushing against some sort of invisible wall, some sort of barrier, around her, Sammael and Jace.

"Cla-" began Sammael, but he abandoned his sentence because Clary shoved the seraph blade into her belt.

"Good girl, good girl. That's right-" he said.

Then Clary took out her stele. She pressed its tip into the wall, she didn't want the wall to open. She didn't want it to fall. She wanted it gone, gone, gone, gone. She guided the stele along the wall. And now everything was moving in slow motion. Out of the corner of her eye she could see Sammael lowering his flags to Jace's neck. A tear tricked down her cheek. Her stele slid over the wood. Then she pulled it away. Now everything was being sucked back into itself, the walls folding into themselves like what happened when demon where slaughtered. It wasn't just the wall, it was the whole house being pulled away, far away, to the Void, Sammael too. Then everything stopped. Froze. Stayed fixed as if the house was half swallowed, half not. But the barrier was gone.

"Clary!" Alec ran up behind her. "Clary? How did-"

"The mirror." she said, "I need it. I need it right now. Right now."

"Clary?" he asked.

"The mortal mirror. Please Alec just trust me, please."

"We can't get it instantly... Clary, try to be reasonable." he pleaded.

"Contact Magnus have him do his teleportation thing with the mirror. Alec I need it now. I few minutes at most."

Alec pulled out his phone and dialed Magnus's number, it picked up on the first ring.

"Magnus! I know this is a lot to ask but could you please, please get the mirror to Simon's house? It's in the institute. Do whatever you have to, Magnus please! ... How long? ... Ok, ok, ok. That's good, that works. Ok, thanks, bye."

Then Alec hung up.

"It'll be here in five minutes." he said, "Does that work?"

"Yes, I think, maybe." said Clary.

The mirror appeared in the front lawn only two minutes later, and Mayrse went to retrieve it, then handed it to Clary. Clary pressed her stele into its surface, drawing the same rune as she had drawn on the wall. The stele slid so fast across the mirror, she almost messed up several times. When she was done she placed the mirror face down on the half collapsed wall. Then things started again everything folded into itself ,and this time it didn't stop, and after only minutes the entire house was gone. It had been pulled into the void, taking Sammael with it.
