I'm going to sit down next to this post, and say encouraging things. :D

I like Bela -- I hope they don't go the route of redeeming her, or making her overly sympathetic, too quickly. But I think she's got layers and reasons for what she does. I'm fascinated by how she doesn't fit and yet is a perfectly logical sort of person to exist in the SPN 'verse. Why NOT someone who is in this for mercenary reasons? It's another facet. She has no powers (that we can see), she's smart and resourceful and manipulative and practical and I agree with you on the damage. Watching her interact with Dean and Sam is just plain fun.
