Welcome to the game, Dylan! I am Kat and I have four kids:
Ian Terrell / Cutter here is one of the shows fighters and generally a very nice guy, just lacking in social skills and determination to interact with people. Basically he's what people would call trailer trash and had a less than stellar childhood, was involved in all kinds of fun criminal activities until he got stabbed during a bar fight. His best friend killed the guy that stabbed him and another guy that happened to be around and Cutter left town with him to avoid the authorities. During that time he met his first and only girlfriend, who was recently killed by witch hunters. Lots of misery here.
Cutter is quite accepting when it comes to people's abilities, but that doesn't mean he can't be creeped out by some of them. And a doctor than can do stuff like that is way up there on his list. Especially since he doesn't trust them anyway and only went to see one if it was really neccessary so far. Like after being stabbed in the lung. But considering his job he'll end up having to see Dr. Prizrakov sooner or later.
Then I have Frankie Moodymistermonster. He can communicate with animals, which is a blessing because he's also a sociopath and doesn't get humans. Like, at all. He grew up in a circus, married a girl a few years ago but that didn't work out too well due to his lack of compassion. Then he left "home" because daddy dearest didn't approve of the divorce, joined a freak show and had pretty much every inch of his skin tattooed. His act here is the Snake Charmer and he lives in his trailer with his three snakes, his best budd Jeffrey (a dog with an alcohol problem) and various injured critters he fosters.
I always find it hard to predict how he will react to other people because he doesn't really care for anyone, but he finds humans in general interesting. Especially if they have talents like that.
Then there's Bernadette Rose Hudson/ Sindarella / Ellafeelgoodtime She is an empath and works at the burlesque show. Ella loves attention and she loves feeling good, parties and stuff that glitters. People with any kinds of strong emotions draw her in and she tends to either take on their mood or rub off on them because she can't fully control her ability - she can to an extent control how she influences people, but she can't just stop.
Ella would adore him if she should run into him with his butterfly net. She is a people person and would most likely annoy him with blunt questions about his life, she tends to do that sometimes. Personal space is overrated.
Annnnd Esther Prynneinnervision is a young mom that works at the Toy Chest. She grew up on a secluded farm in a very religious family. When she got out at 22 the first thing she did - after learning that special abilities run in her mother's side of the family - was sleeping with a stranger and getting pregnant. Esther isn't as naive as she used to be, she has been on the road ever since and does everything she can for her daughter. She is a telepath and because she tried her best to ignore it for most of her life she is improving. It works best if she touches people, but she can get brief glimpses into people's heads if she really concentrates.
Esther has a little girl that tends to get into all kinds of trouble so he might see her more often than she likes.
