It was difficult to keep his worries from taking over as he watched her, knowing that her exhaustion was because of him. He wondered why she'd done it. She'd given herself to a monster, then returned to rescue him. Magnus had been one of Valentine's followers and then Sebastian's.

Alec was someone that Sebastian hated on principle for his preferences. The fact that he was in love with Jace had made him the ideal target. She should have hated him just as much as Sebastian did, but instead she'd saved him.

Now he had to do everything he could do to save her.

Stretching out beside her, he almost asked why she'd done it but he remained silent, keeping as much distance between them as possible before realizing that no matter how much he wanted to reassure her that he wouldn't hurt her.

"Can I..." Pausing he tried to think of what to ask. "I don't want you to get cold, but I don't want to hurt you."
