Izzy's pov
Izzy screamed. She screamed until her lungs burnt with agonizing pain. Izzy was surprised in herself, she actually had no clue as to why she screamed-apart from the fact she felt much better doing it.
Alec's pov
Alec immediately jumped up when he heard his sister's screams. Izzy had only screamed once or twice in her life-so something awful must have happened. Alec ran as fast as he could to the living room and had to blink to make sure he wasn't dreaming. The scene was Izzy knelt down staring at some strange marks on the floor and Jace- Well Jace's face was blank and pale. Alec knew he wouldn't be able to go to lunch with Magnus now.
Jace's pov
Jace felt nothing. He felt hollow-like someone had winded him or taking out his organs. There was only two words coming and going through his head. The first word made him feel sick with worry, the second word made him feel so angry that he wanted to punch the wall. Clary,Clary,Clary
