You have something on your neck.
What
Looks like a bite mark, what were you doing out all night, anyway?
Nothing. I went walking in the park. Tried to clear my head.
And ran into a vampire
What? No! I fell.
On your neck?

I don't hate you, Jace."
"I don't hate you, either."
She looked up at him, relieved. "I'm glad to hear that—"
"I wish I could hate you," he said. His voice was light, his mouth curved in an unconcerned half smile, his eyes sick with misery. "I want to hate you. I try to hate you. It would be so much easier if I did hate you. Sometimes I think I do hate you and then I see you and I—"
Her hands had grown numb with their grip on the blanket. "And you what?"
"What do you think?" Jace shook his head. "Why should I tell you everything
about how I feel when you never tell me anything? It's like banging my head on a
wall, except at least if I were banging my head on a wall, I'd be able to make myself stop."
Clary's lips were trembling so violently that she found it hard to speak. "Do you think it's easy for me?" she demanded.

Magnus glanced at Alec and raised his eyebrows "Boo", he said. Jace was grinning. "Come on,surely you've got a phobia or two. What scares you?" Alec thought for a moment. "Spiders," he said. Clary turned to Luke. "Have you got a spider anywhere?"
Luke looked exasperated. "Why would I have a spider? Do I look like someone who would collect them?"
No offense," Jace said, "but you kind of do.

Mother." Alec's voice as he interrupted his mother was firm, implacable, and not
unkind. "Father. There's something I have to tell you." He smiled at them. "I'm seeing someone."
Robert Lightwood looked at his son with some exasperation. "Alec," he said.
"This is hardly the time."
"Yes, it is. This is important. You see, I'm not just seeing anyone." Words
seemed to be pouring out of Alec in a torrent, while his parents looked on in
confusion. Isabelle and Magnus were staring at him with expressions of nearly identical astonishment. "I'm seeing a Downworlder. In fact, I'm seeing a war—"
Magnus's fingers moved, quick as a flash of light, in Alec's direction. There was a faint shimmer in the air around Alec — his eyes rolled up — and he dropped to the floor, felled like a tree.

Jace threw his hands up. "So it doesn't work."
"Not necessarily," Luke said. "There might simply be nothing going on that might activate it. Perhaps there isn't anything here that Alec is afraid of."
Magnus glanced at Alec and raised his eyebrows. "Boo," he said.
Jace was grinning. "Come on, surely you've got a phobia or two. What scares
you?"
Alec thought for a moment. "Spiders," he said.
Clary turned to Luke. "Have you got a spider anywhere?"
Luke looked exasperated. "Why would I have a spider? Do I look like someone who would collect them?"
"No offense," Jace said, "but you kind of do.

The funny thing about mundies is how obsessed with magic they are for a bunch of people who don't even know what the word means.
