Well, I always wanted to explore the whole "science geek with fangs" idea, especially with some Victorian Steampunk thrown in. The hematology thing is as much so she can study her own condition as for the free noms. And yeah, that would be funny. Arienne's initial contact with any supernaturals has the potential to be funny/awkward, as she's a very skittish total noob.
Arienne's a bit of a crusader, and she'll start by figuring out if local clinics are being properly supplied. She'll likely look at any local Reservation clinics most closely, since they tend to get neglected the most supplywise. :/ That means she's on the road throughout the area and talking to a lot of different sorts of people. This will also keep her from hiding in her lab too much initially! That could bring her in contact with anyone, especially as she'll need to jump from cafe to bar to diner to use wi-fi on the road.
