Alright, good. Everyone agrees that this is just in-character aggression, and that the two rogues dislike each other. Play it out in character that you don't like each other, fine... just work together, the lot of you. And if you need an arena to play out your anger, it turns out that, due to a mysterious, underground stream, the square in the middle of town in a muddy mess, perfect if two women get angry with each other, and need a place to fight. >_>
