Yes permissions! If Bigby encounters Jolene, she's all over the place with emotions and can't even hide them in her expression -- but if he needs smell to tell him that she is pissed off or scared or really damned sheepish, I'm fine with that.

I've got a subplot with her going on right now that involve the Biomatrix; it's linked to themes of cancer and alien spores that colonize biomass and link it into a collective. Unlike the Borg, Biomatrix allows its living hosts autonomy until death, at which point it takes over their corpses and uses them like... do you live anywhere with co-op run rent-a-cars? Imagine a central bank of people who have kicked the bucket and are living an afterlife, who can borrow these rotting bodies if they have any need to interact with the living. It's gross and weird. The Biomatrix currently only has possession of Jolene and her clone, but over the next few months I plan on having it begin to root around into the wilderness' biomass. It will be wafting in themes of 'nearly fluorescent red' as well as 'fungal' or 'spore-like'. I'll leave it up to you as to whether this is bad news or not; I'm playing it so that at the moment the Biomatrix has no intention of taking over everyone, monster-like, but of course its motives and behaviours are always dodgy as hell. :D
