Dean Winchester: How do you sleep at night?
Bela Talbot: In silk sheets, rolling naked in money
Bela is selfish and manipulative, she's willing to kill people to get what she wants. She's reckless and smart, not afraid to take risks, and she usually only cares about her own wellbeing. She doesn't like to get reduces to the word "thief", because she steals very unique and partly dangerous supernatural things that she sells for millions of dollars.
