Julian's room was small, and painted an incongruously cheerful shade of blue. A white-painted four-poster bed dominated the space. Emma tugged him toward it, sitting him down gently, and went to bolt on the door.

“Why are you locking the door?” Julian raised his head. It was the first thing he'd said since they'd left Ty's room, though he’d followed her calmly enough.

"You need some privacy, Julian," she said. She turned toward him; God, the way he looked broke her heart. Blood freckled his skin, darkened his stiff clothes, had dried in patches on his boots. Livvy's locket glittered in the hollow of his throat, though it had dangled against Livvy's sternum. Emma remembered that locket: a gift from Julian to his sister when she'd turned thirteen, it had belonged to their grandmother. It had a circlet of the family thorns on the front, and Julian had added an etching to the back: a pair of crossed sabres, Livvy's weapon.

It held a picture of Ty, Emma knew. She'd barely noticed Livvy wearing it at the Council meeting, though she knew Livvy often wore it when she was feeling nervous, the same way Emma kept tight hold of Cortana.

She wished she'd noticed Livvy more in those last moments, paid more attention to her, rather than worrying about the Cohort, about Manuel and Zara and Jessica, about Robert Lightwood and exile, about her own broken, messed-up heart. She wished she had held Livvy one more time, marveling at how tall and grown-up she was, how she had changed from the chubby toddler she recalled in her own earliest memories.

"Don't," Julian said, roughly.

Emma came closer to him; she couldn't stop herself. He had to look up to meet her eyes. "Don't do what?"

"Blame yourself," he said. "I can feel you thinking about how you should have done something different. I can't let those kind of thoughts in, or I'll go to pieces."

He was sitting on the very edge of the bed, as if he couldn't bear the thought of lying down. Very gently, Emma touched his face, sliding the palm of her hand across his jaw. He shuddered and caught her wrist, hard.

"Emma," he said, and for one of the first times in her life, she couldn't read his voice — it was low and dark, rough without being angry, wanting something, but she didn't know what.

"What can I do," she breathed. "What can I do, I'm your parabatai, Julian, I need to help you."
