Enzo and Caroline have been spending a whole lot of time together on The Vampire Diaries. They must be hooking up sometime soon, right? Well, according to executive producer Julie Plec, that won't be happening right now.

During Thursday's episode titled "Rescue Me," there will be problems with Stefan's doppelganger, an EMT living in Atlanta. Enzo and Caroline will go on a journey together to have him killed. Yet, the little trip won't unite them romantically.

"I think it's fairly safe to say now after five years that Caroline has chemistry with everybody and so there's definitely some fun banter and some flirtation that she indulges on a small level because Enzo is a highly mischievous flirt, but I think it's really more just he gets a kick out of digging at her and poking at her," Plec told E! Online. "That's just the kind of guy he is. He likes to rile people up and she's very easily riled."

In fact, Caroline will also share some chemistry with Stefan on Thursday's episode.

"They have a nice scene in the Traveler camp in the next episode," Paul Wesley, who plays Stefan, told Zap2It about the next episode. "They have nice, mini, friendly/romantic moment. It's more friendly than anything else. But personally, yeah, I would love that to turn into something romantic."
