She had to bite back any comments or nasty things she was going to say, because he vanished on her. Kate had no idea what he meant by 'the Son' though she was assuming he meant himself. Of course she had to pick an lunatic to try and piss off. And of course the lunatic had to rub her the wrong way. "Fuck." she muttered. Of course he wasn't human. They were never human. Though what she was dealing with, she had no idea.
For a moment she didn't move. She didn't hear anything, and she didn't smell anything. Kate had excellent night vision, and there was no sign of the guy. She stood frozen for a moment, waiting for him to come out and attack.
Slowly, looking around her as she moved, she turned around. If he actually was gone, she was making a sprint for home. Running back to apartment from here was no problem, the girl was a natural sprinter. She was going to need to do some heavy duty research on who and what she was dealing with. All she saw was more darkness. Eyes flicking around, she took one step forward, fully read to break into a sprint.
