"Normally I am not so reserved in fighting but even I know that there's no need for blood staining the floor here."

Camilla is a fighter and someone who would gleefully beat the living tar out of her enemies and make sure they would not get up. For why have an enemy and prove to them that you are stronger? However, the factors here are different: there's no war to be fought between two easily spotted sides and blindly following one because of ideals or loyalty. From what she has saw, it's just people trying to figure out what to do about a problem not very well known it seems. And a drunken lout doesn't count as an enemy but she will show them that she's not a damn pushover.

As for the brawl...they can handle it inside as she pushes the door open and out of the stale air of beer and other weird smells.
