Startled, she moved to act on instinct and strike the kid. It was just at the very last moment she noticed the towel and instead of hitting him her hand changed from a fist and held the back of his hand. "Careful." She exhaled, her heart pumping more blood as the adrenaline coursed through her in response to his shock. "I could have really hurt you." Which probably sounded a bit amusing coming from someone so small.
Slowly she pulled the towel away from his nose and then let him go back to holding it there. "Come on, take a seat... let's have a look at you." She gestured to the lowered EMT cart that had been sort of converted into an exam table. "Looks like someone really got you good huh?" Okay, her bedside manner wasn't the best.
