Lauren Cohan: (on her character in "Supernatural") These characters are ass-kickers. My character, Bella, was brought on to compete with the boys. She's a mercenary, so she's out as a solo artist. She has her own agenda. She's very centered and focused on what she's doing. She has commands from people who need a lot of the same stuff the boys need, but she sells it, and she's very much about negotiating. Sparks may fly between Bella and the boys. Sparks may fly between Ruby and the boys. You'll just have to wait to find out. But, I think there's going to be some fighting, before there's ever any romance.
