Tim's entire body tensed immediately, eyes squeezing shut, jaw clenching, knuckles turning white, and it took a lot of effort to keep himself from trying to move back or double over. He managed, at least, not to make a lot of noise about it, keeping it to low, pained grunts in his throat. It was maybe worse than the actual process of getting stabbed, but he'd been running on adrenaline at the time, so he hadn't actually felt much of the initial stabbing.
