But being away from everything and everyone you knew had impacts, that had dying. Still, it didn't stop her from being a rude smartass on occasion.
"And you are?" She shot back before thinking; Don't insult the man capable of running you off into a cold ditch. But then, she would survive that now wouldn't she?
