Brudd watches Quagmire's threat enviously, he's never been good at intimidating people, being too inclined to laugh. Usually he just uses awkward facts, such as if we don't make a deal I'm going to shove a bastard sword up your arse, as negotiation points.

"Well killin' the Dwarf'd be more trouble than its worth, might get us on the wrong side of the Merchants if we make it too obvious. So I suppose he's got us, dependin' on how inconvenient his task is. So lets find out what we want he wants us doin' and we can always amend our strategy as needed."
