She's moved enough to prop herself up against a wall, her leg sprawled in front of her. Alec had gone for help, probably for Magnus, but she almost hopes he doesn't find him. She can feel the poison in the demon bite despite the countless iratzes Alec has covered her in and some part of her wants it to win. Max died and so she doesn't deserve to live, not when she was the one who was supposed to save him. She was the only one who was there, the only one who could have known, but she wasn't good enough. Wasn't a good enough sister to save him, not a good enough Shadowhunter to fight Sebastian. Not a good enough Shadowhunter to fight even this demon, apparently, but she supposes if she has to go out, this is fitting enough.

She'd let her eyes fall mostly closed but she forces them open when she hears Luke. She can sense him without needing to be able to see him. He feels more werewolf than normal which means he's half changed, and Isabelle forces her eyes to focus so that she can see him.

Isabelle shakes her head. "No," she protests. Alec has gone to get help because that's what Alec does, but she doesn't want help, she doesn't want somewhere safe. "He died, Luke," she mutters, because that's all she can think about, the only thing that she can bring herself to say.
