"Not planning on killing anyone. I don't kill people. I kill monsters." There had to be something like monsters where she was from, right? Something that would let her understand what it was he did.
He felt a twinge of guilt. Yeah, he didn't intentionally kill people, but... Summer. Clover. Maybe the girls. They'd died because he wasn't good enough. Because he hadn't been there when they needed him or because he'd made the wrong choices. Wasn't he lying to her, just a little bit, making that claim?
Being a liar, Qrow tried to be better than that. He tried to balance out all the mistakes he made by at least being honest about it.
Maybe he could balance it out a little more by soothing this girl out of whatever dark place she was trapped in right then. Even if he did end up sleeping somewhere else, after.
"Look. I'm just gonna sit right here." Qrow lowered himself to the ground; it wasn't as easy as it had been ten years before, when the girls were young enough to want Uncle Qrow to get down and play with them. "Can't do anything to hurt you sitting over here, right? Won't come any closer til you tell me it's okay."
