Damon and Bonnie are going to have an interesting yet complicated relationship in season 7 of the CW's "The Vampire Diaries."

Kat Graham's Bonnie is the reason why Elena (Nina Dobrev) is no longer with Damon (Ian Somerhalder), and he is not going to waste an opportunity to remind the Bennett witch of the sacrifice Elena made.

Season 6 finale saw Kai casting a sleeping spell on Elena and linking her life with Bonnie's in such a way that Elena will not wake up as long as Bonnie lived. This means, Damon will have to be away from his ladylove for at least six decades, and this is something that he will constantly remind Bonnie, who has survivor's guilt.

"She has survivor's remorse," executive producer Julie Plec told Entertainment Weekly. "But she doesn't want to be punished for it, either, so she's trying to take a stand against anybody that would make her feel bad that she survived."

However, this does not mean Damon and Bonnie will be the enemies we saw in the first few seasons of the vampire drama. The first half of season 6 saw them trapped together in Kai's prison world, and their time together gave them an opportunity to get to know each other better.

This was one of the reasons why Damon decided to save Bonnie and sacrifice Elena in the season 6 finale, and now Bonnie feels responsible for Damon. She is going to take Elena's place and be the voice of reason for Damon.

"Bonnie has sort of taken it upon herself to be the uninvited chaperone, which is funny because she and Damon have so much unspoken between them — the guilt, the resentments, the gratitude, there's a list of things they're dealing with," Plec told TVLine.

"Watching them air it out together is actually really nice. We'll continue to watch their friendship build, because they really do owe each other a lot. They're going to go through this whole thing together, which is a fun dynamic we're exploring," the showrunner added.

"The Vampire Diaries" returns to the CW in October.
