((Addendum to my previous post, as a result of a couple of messages.))
Fiona chuckles at this little display, but will occasionally shoot Stultus a thoughtful, almost appraising look.
Apparently Fiona's poker face isn't what it normally is ((Com 2 + Guile (Hide true feelings) 3 + (die roll of 0, but not a botch) = 5)), so anyone who beats a 5 can tell that she seems to be...figuring the logistics of a tryst with Stultus.
