My speculation: I can see Assallya and Darius becoming the party's sassmasters. I imagine Sumia will turn out to be the strict: "If you are anything other than lawful good, then I owe you at least one stern lecture before this adventure is over" type. I don't know about the Orc Cleric, but he seems like a wise and honorable type, so I would expect a few disapproving glares. Joric doesn't sass people so much as make them cringe (and occasionally laugh) with his stupid jokes. I'm not sure how much sass we can expect from the human rogue lady whose name I will butcher if I try to spell, but there will probably be a few arguments given her apparent temper. As for Poohead's own characters, I have no idea, but the Duergar is probably used to dealing with angry squabbling humans.
