I'm honestly surprised that of all the characters to first get into an argument with an NPC - I mean, there's a veteran mercenary, a warrior that's murdered innocents in war, and a scholar being whispered dark thoughts - that it's the well-dressed, intelligent-by-occupation alchemist that throws down a gauntlet first. Ayla's going to snark at Ro'en a bit more than necessary now. First impressions and all that.
