Whereas Formerly Suicidal actually had a decent sense of self-preservation (or so it seemed), Reiko's flight-or-fight mechanism was heavily geared toward fighting. When she heard the gunshot, she stopped dead in her tracks and turned toward the sound, gun at the ready in what could have easily been a comical 'western shootout' parody if only someone else had been aiming toward her.
Instead, what she saw was Monster Bait's apparent victory against the beast. She wasn't quite sure how that made her feel, but there was a strange stirring of frustration within her. Jealousy, perhaps. Or maybe even embarrassment at not having been able to kill the creature before running away. Whatever the unidentified emotion was, it made her just a little more mean-spirited... enough to chuckle lightly when she noticed the fallen man. He was already getting up, but she imagined he was in at least a small bit of pain; and that was, for some reason, worthy of a small laugh.
She scrubbed a hand through her hair, still refusing to re-holster her gun, and 'casually' walked behind him toward the hopefully-dead monster and its presumed slayer. With the monster no longer at the top of the list of pressing matters, there was something else which she felt needed addressing...
"Where did you come from?" She approached the monster, tilting her head as she observed it. Easily, she could have been mistaken for someone who didn't really care that there were more survivors. And just yet, she wasn't quite sure if she did care beyond the fact that Damon had wanted her to find any that existed. "I thought I was the only one out here." Her eyes finally darted from one man to the other then back down to the monster. "Aside from these poor freaks."
