SPOILERS: 'The Vampire Diaries' Joseph Morgan Teases Klaus And Caroline's Relationship

While it may seem like the entire focus of this young fourth season's The Vampire Diaries has been on Elena's (Nina Dobrev) transformation from human to vampire and the perpetual complication she calls a love triangle between brothers Stefan Salvatore (Paul Wesley) and Damon Salvatore (Ian Somerhalder), the show hasn't forgotten about its supporting characters — namely, Klaus (Joseph Morgan) and Caroline (Candice Accola).

While there have been a lot of developments that have caused a transformation in the Klaus-Caroline dynamic, including Caroline finding out that Klaus was inside Tyler's (Michael Trevino) body, there may still be more to come.

"We'll certainly see their relationship — but I don’t mean relationship in the sense that they’re dating — but we’ll certainly see the dynamic between them develop," Morgan told Entertainment Weekly. His character's relationship with Accola's Caroline, Morgan claims, "brings out Klaus’ humanity. I love playing the more charming side of him and the scenes with Caroline really allow me to do that. So I hope he has a shot with her. I think everyone deserves love and a second chance. I wonder how much of a compromise he’d have to make in order for her to come around to him and whether he will be able to make that compromise."

And that's not all The Vampire Diaries is dishing in the way of spoilers. After Elena feeding on Damon's blood at the end of last week's episode raised some eyebrows, executive producer Julie Plec revealed the relevance. "That's a little bit of a shout-out to the books, but also just to vampire folklore in general. If you look at any of it metaphorically, it’s a very intimate exchange of bodily fluids. So you can read into that what you will," she said.

As for the meaning behind Connor's tattoo, which Matt couldn't see? "We will know what that tattoo is and what it means by the end of episode four," Plec promised. So tune into The Vampire Diaries this Thursday at 8 p.m. EST on the CW.
