"Perhaps there isn't anything 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." "You know"---Alec's tone was sour---"Maybe this was a stupid experiment." "What about the dark?" Clary suggested. "We could lock you in the basement." "I'm a demon hunter," Alec said, with exaggerated patience. "Clearly, I am not afraid of the dark."
