She shook her head. “You shouldn’t have waited.”
“Cristina.” He came toward her, his hands outstretched. “Please, if you don’t believe anything else, believe me that I have always loved you. Do you really think I have lied to you since we were children? Since the first time I ever kissed you and you ran away laughing? I was ten years old—do you really think that was some kind of plan?”
She didn’t reach for his hands. “But Jaime,” she said. “I’ve known him just as long. He was always my friend. But he wasn’t, was he? He said things no friend would say, and you knew he was using me, and you said not a word.”
“I was going to tell you—”
“Intentions are nothing,” Cristina said. She had thought she would feel some relief, finally telling Diego why she hated him, finally unburdening the knowledge of what she had heard. Finally severing the thread. But it didn’t feel severed. She could feel the bond connecting them, as she had when she’d blacked out in the crashing car outside the Institute and woken up with Diego holding her. He’d been whispering in her ear that she would be all right, that she was his Cristina, she was strong. And it had felt for a moment as if the past months had been a dream, and she was home.
“I must stay here,” Diego said. “These killings, the Followers, they are too important. I am a Centurion; I cannot abandon a mission. But I do not need to remain at the Institute. If you want me to go away, I will.”
Cristina opened her mouth. But before she could speak, her phone buzzed. It was a message from Emma. STOP MAKING OUT WITH PERFECT DIEGO AND GET TO THE COMPUTER ROOM, WE NEED YOU.
Cristina rolled her eyes and shoved the phone back in her pocket. “We’d better go.”
The sky outside the Institute had turned the color of what was very late night or very early morning, depending on your point of view. It had always reminded Julian of blue cellophane or watercolor: the intense blue of evening turned translucent by the imminent arrival of the sun.
The inhabitants of the Institute—all but Arthur, who slept on soundly in his attic—had gathered in the computer room. Ty had brought papers and books from the library, and the others were going through them. Tavvy was curled up asleep in the corner. Piles of empty pizza boxes from Nightshade’s were stacked on the table. Emma didn’t even remember them being delivered, but most of them had been eaten. Mark was busy glaring at Cristina and Diego, though Diego didn’t seem to notice. He didn’t seem to notice Drusilla staring at him with saucer eyes either. He didn’t notice much, Julian thought uncharitably. Maybe being ridiculously good-looking was more time-consuming than it seemed.
Emma had finished telling the story of the way she and Cristina had tracked down Sterling and the things he had told them on the car ride home. Ty had been taking notes with a pencil, a second pencil stuck behind his ear. His black hair was ruffled up like a cat’s fur. Julian remembered when Ty had been young enough that he could reach out and smooth down his younger brother’s hair when it got too messy. Something in him ached at the recollection.
“So,” Ty said now, turning to Diego and Cristina, who was sitting beside Diego. She was barefoot, one of her pant legs rolled up and her calf bound with bandages. Every once in a while she would shoot Diego a look out of the corner of her eye that was half suspicion, half relief—that he’d helped her? That he was there at all? Julian wasn’t sure. “You’re a Centurion?”
“I studied at the Scholomance,” said Diego. “I was the youngest aspirant ever to become a Centurion.”
Everyone looked impressed except Mark. Even Ty. “That’s like being a detective, isn’t it?” he said. “You investigate for the Clave?”
“That is one of the things we do,” said Diego. “We stand outside the Law that precludes Shadowhunters from involving themselves in issues that relate to faeries.”
“The Clave can make that exception for any Shadowhunter, though, in exigent cases,” said Julian. “Why was Diana told we couldn’t investigate? Why did they send you?”
“It was judged that your family, with your connection to the Fair Folk, would not be able to objectively investigate a series of murders where some of the victims were faeries.”
“That is entirely unreasonable,” Mark said, his eyes flashing.
“Is it?” Diego glanced around. “From all I have heard and seen, you appear to have mounted a secret investigation into this issue, telling the Clave nothing about it. You have compiled evidence that you have not shared. You have discovered a murderous cult operating in secret. . . .”
“You make it sound so shady,” Emma said. “So far all you’ve done is show up in L.A. and shoot another Shadowhunter.”
Diego glanced over at Julian. “It’s mostly healed,” Julian said. “Mostly.”
“I bet you didn’t report that to the Scholomance,” said Emma. “Did you, Perfect Diego?”
“I have reported nothing to the Scholomance,” Diego said. “Not since I found out Cristina was involved in this as well. I would never hurt her.”
Cristina blushed furiously.
“You’re a Centurion,” Ty said. “You have vows—”
“Vows of friendship and love are stronger,” said Diego.
