Meanwhile, in a shocking romantic development, Caroline put away her disdain for Klaus and gave in to her attraction as she and the Original got it on in the woods! But even though the hybrid promised to leave afterward, there was still plenty of awkwardness in store: Rebekah left behind Care’s ex Tyler, who really, really hates Klaus, as a parting gift for Matt.

Below, executive producer Julie Plec previews the schemes Katherine will cook up as Elena and how they’ll shake up the Elena-Stefan-Damon love triangle. She also hints at Bonnie’s crucial role moving forward and whether we can expect more Vampire Diaries/Originals crossovers.

TVLINE | You have to assume that Katherine’s going to have all sorts of crazy, wacky hijinks.
It is such a quintessential, bitchass Katherine Pierce move that she has to live up to it with her behavior. [Laughs] Because you can’t go that hard without delivering — and she does deliver. As we know, Katherine’s got her eye on Stefan. So just as Damon and Elena have admitted to themselves that they’re ready to fight for their relationship, all of a sudden, Elena is no longer in possession of her own body. Katherine’s first order of business will be to try to figure out ways to get Damon out of her life for good. And then the domino effect of all of her moves is just horrible and tragic and mysterious in that wicked way. She really starts screwing up people’s lives, left and right.

TVLINE | Who is the most suspicious about what’s going on with Elena?
Everybody’s going to have a moment of suspicion along the way. The question, as we move forward, is going to be how long is it going to take before somebody figures it out? And when they do, how much damage will have been caused?

Vampire Diaries Season 5 SpoilersTVLINE | And Damon, as the guy who was Elena’s boyfriend just a short while ago, how does he react?
He’s all ready to go ahead and do what he can to get Elena back and can’t understand, in the beginning, why she’s not returning his phone calls. [Laughs] So [the next] episode spirals from there. But Damon’s working really hard to reclaim his undying and eternal love for Elena just as Elena, aka Katherine, is trying to extricate herself from Damon’s life.

TVLINE | Caroline and Klaus finally acted on their feelings – but it came with the caveat that he would never come back. Are things really over between them? Can Caroline really put this behind her?
I think they can both put it behind them because they both, admittedly, have other lives and other obligations they need to deal with. The thing with Caroline and Klaus is, she’s always been drawn to him and has this deep-rooted attraction to him that scared her… And yet, she wanted this. She was acting on her most base impulses and trying to get something out of her system. For Klaus, of course, it’s something we know that he’s always wanted. But he’s got obligations. He’s got a life that he’s got to get back to in New Orleans, baby on the way and all that stuff.

TVLINE | And Tyler’s back. Does that send Caroline into a tailspin?
What should be a joyful occurrence for everybody, which is Tyler returning safe and sound, has the world’s most awkward timing for Caroline. She’s going to have to deal with the fallout of the decision she made to give in to her feelings for Klaus.

TVLINE | There were a couple Originals in the episode. Are we going to see more crossovers between the shows this season?
We don’t set out to plan them on a schedule. If something comes up when we’re breaking story and feels organic and like it would be enjoyable for the characters and not stick out like a sore thumb, we’re open to it. But this was the big one for the time being.

TVLINE | And what’s coming up for Bonnie?
She’s going to start intersecting with the Traveler agenda. We’re also going to meet some new witches that are going to take a particular interest in her despite the fact that she can no longer practice magic. As we get closer to the end of the season, she becomes quite integral not just to the plan to save herself and her friends from danger, but also to – in an exaggerated and yet, appropriate, phrase – save the world and everyone.
