First things first. Without revealing too much about what goes down tonight, you should know that Bonnie and Stefan will have a lot to do with each other, and that’s something Kat is supremely happy about. “I was like, ‘Oh yay, I get to work with Paul [Wesley]!’ And then I started really thinking about how the character might feel…” And the repercussions on her relationship with Elena. Kat says she knows how the new Stefan-Bonnie development will affect her BFF-ery, but says coyly, “I’m not telling you!” You know what that probably means: Some shiznit’s gonna go down, people. At least, that’s our guess.
Also in the troubled-relationship zone: Bonnie and Jeremy, who already are on the splits, and have yet another (greater) obstacle coming their way. “She is going to be forced to deal with her feelings about him [spoiler omitted—we can't say!] and what that means to their relationship, if they still have a relationship or where they’re at.”
