I should probably introduce myself/characters hm? My name's Maki (Not really, but go with it ;) ) and I have four characters. Harmony Gold, who is the account I'm using to talk to you, is a whore working in the red light district and living in an inn. I don't know how she'd interract with Gert. Nicely, I guess :P
Sheldon Wilcock is the doctor of Sedona. He's a gentleman, but generally keeps to himself. So if your deary gets into any scrapes, Wilcock will be the man she goes to.
Francine Smith is very shy, very meek, and quite old so I can't imagine these two having much interaction. She's a barmaid at an inn anyway. Her son, Cedric, works at a clothing store. He's a handsome young man... With one arm (He lost it in the train bombing.) He's currently got a 'bad boy' rep because he PUNCHED THE PRIEST. (He's not violent though <3 Just stressed.)
Other than that I run a pimp NPC who keeps a very watchful eye over the Red Light District. If he sees her there causing a fuss or getting in to trouble he'll probably shoo her out (or get someone else to.)
