Toss up what was more adorable right now: William's blush, or his apparent belief that any amount of belatedly dignified behaviour was going to salvage this. Gabe just grinned and shoved his hands in his back pockets (looked momentarily startled; pulled out an extremely squished lump of clay and tossed it aside; shoved his hand back in).
"Everyone'll pull through," he said, with a casual shrug, and then memory caught up with him, and his grin slipped. "Almost everyone." He'd actually quite liked the nurse, even if she had made him stick to the recipes and actually label things properly. She'd put up with almost absolutely none of his rubbish and reacted with masterful equanimity when he'd said things like I'm going to poison one of the professors.
He pulled a hand out of his pocket to scrub it over his face, realising, "Shit, we were so fucking lucky." It could have been so much worse.
