He wasn't afraid of her - not nearly as much as he probably should be, at any rate. Wary, yes; nervous, definitely; paranoid, always. But it was hard for Peter to truly feel afraid of the various dangers to be found in this world, even when he knew full well what they were capable of doing to him. Maybe it was just his own fucked up psyche, but after vampires, nothing else seemed to compare in terms of outright fear.
Peter was not afraid, but still tense with adrenaline as he turned around. His hands were steady as he brought up the shotgun to aim vaguely in her direction. He didn't fire, though. Not yet. "Hi," he bit out, eyes never leaving her. Showtime.
