I'm just the opposite. I like Ruby. I know that she has her own agenda but she kicks so much ass. Literally.

Bela is a whiny bitch. As long as it's not about her, she's really uber self-confident. But as soon as it's about her precious life, she comes back crawling and whining for help. If she at least was a part of the main plot, I could accept her. But I just don't like that suddenly, they are turning her from a cold-hearted sociopath into misunderstood girl with a sad past.

I don't like her at all, sorry. For me, she's ruining every scene that she's in because she always one-ups everyone, including Bobby who wasn't conned by a demon for christ sake, and always gets away with it. That's not a way to write a character you want the fans to like.
