Sam
As they sped down the road, Sam had to repress the constant urge to look back and check on the young woman. The few times he did, she seemed calm, and he had trouble believing that anyone normal would react so little to what had happened. She'd been attacked; no, he corrected himself, she had gone on the attack. It was until Dean had called down the alleyway that she had come under any sort of threat. As he glanced at Dean, he could already tell his older brother was thinking the same thing. They would need to test her before they could trust she wasn't trying to take them down as well. And they needed to do it fast. Kaia glanced out the window and frowned, her first real show of emotion yet.
"Where are we going exactly?" Her voice was soft, but Sam couldn't seem to find any sort of fear in her tone. If anything, she just sounded curious. Dean gave a quiet huff, and Sam realized he was going to have to be the one to explain.
"Just outside of town. We just have a few questions we need to ask you about what happened tonight." Sam was sure to use the same tone he used when he told people he was with the FBI, hoping it would keep her from asking too much. He was disappointed.
"Just for the record, I hadn't known the guy was some kind of freak when I went after him." She turned to look at each of them in turn. "You guys didn't look all that surprised. What, are you guys like the X-Files or something?" The brothers shared a look, and Sam debated with himself on how much to tell her. Dean shrugged, letting his brother know that he didn't care either way.
"Not really. We don't work for the government or anything like that." Sam glanced back, finding Kaia giving him a openly curious gaze. He bit back a sigh and continued. "Dean and I are hunters. We basically go around finding 'some kinds of freaks' and we take them out. The guy you fought off, he was…well, a bad case." He softened a bit. "You saved someone tonight, so…I guess you did good. Thank you."
"Now, you get to explain how you did it." Dean piped up, glancing in the rearview mirror. Sam and Kaia turned at the same time, and Sam was grateful Dean had asked the big question on the younger man's mind. Kaia seemed to hesitate before answering him quietly.
"I don't know. Adrenaline, maybe?" She shook her head before continuing on. "All I know is, I went to stop him, and he hit me in the face. After that, I just…I heard a roaring in my ears and I was prepared to kill him, whatever it took." They all fell silent for a minute; Sam's mind spun with what possibilities it could be. "That's what it's like, right? When adrenaline takes over?" Dean shook his head.
"Even with adrenaline, there's no way you should have been able to faze him. We've fought his kind before, and no amount of power or adrenaline has ever let us land a punch like that." Dean's gaze hardened as it focused on the road, and Sam nodded.
"So, what does that mean?" Kaia asked quietly. Both Winchesters remained silent, and she leaned back in the seat. "You hunt freaks…and I might be one." She didn't sound sad; no, to Sam, she sounded a bit angry. Dean glanced to him again, clearly concerned, and Sam shook his head.
"There's no guarantee." Although, he sincerely hoped they didn't have to kill her.
