Not the way Caroline was jealous, that was really superficial. I'm talking more on the lines of envy. It's pretty easy to see that Bonnie doesn't have the strong back up system that Elena does. It would make sense for her to envy that. I could see that envy tainting their friendship for a while, and I wouldn't blame her. I know I would feel the same way. Bonnie needs more of a support system, but everyone she meets keep leaving
