I am going to say Harmony will have a basic intuitive understanding of the easy gestures, because of her skills. Beyond that I will roll.
Also @The Angry Goat, I am probably going to need Gail's help in understanding Lautrec, if he knows a bit of the lingo. I think it'd be cool if he did, since he is a man of many circles. If not it's cool too, that'd be just as interesting, either way.
But once everyone is together the narrative will continue.
