Joss nodded stiffly. He could hear her, though his racing heart didn't seem to. His body felt shot with adrenaline, and kind of like he wanted to be sick, but mostly he still felt desperately like he should have got out sooner, and that it was basically the end of the world that he hadn't.
If he'd got out sooner - if he'd been there a little sooner - and suddenly his memories were mixing up and it was Kenzie who was opening her dead eyes and not Margo, Kenzie all cut up and dead and Kenzie who might still be alive if he'd been there sooner. He'd been so sure she'd opened her eyes, he'd been so sure he'd been there on time, this time.
"I'm okay," he said, trying to believe it, but failing, because suddenly he didn't know if he was panicked or distraught - both, both, so he burst into into tears on the peas.
