The second episode of "The Vampire Diaries" season 8 saw Stefan (Paul Wesley) proposing to Caroline (Candice King), and the latter accepting it. Fans of "The Originals" were not in favor of this as it may mean she won't be appearing in future crossover episodes and that her romance with Klaus (Joseph Morgan) is at an end.

However, as per a report from Mobile N Apps, there is still a chance of Caroline moving over to "The Originals" season 4, and her relationship with Klaus still has some legs to it. Executive producer Julie Plec had confirmed that characters from "The Vampire Diaries" were crossing over, and it is possible that Caroline is one of them.

Unfortunately, Plec did not state which characters were coming over once "The Vampire Diaries" ends. It is widely speculated that Stefan and Caroline's marriage won't last long or that their wedding won't even happen because of upcoming events on the show, and this may force Caroline to get back with Klaus.

"The Originals" season 4 is also going to feature a five-year time-jump in its premiere, according to Game N Guide. During this interval, it is possible that Stefan and Caroline's relationship may have gone south, and the latter may have left her home and husband to go back to Klaus and join him and Elijah (Daniel Gillies).

Klaus' story does not just end with his relationship with Caroline. Speaking to Entertainment Weekly, Plec also confirmed that Klaus' daughter, Hope (Summer Fontana), is going to play a major role in season 4, and she may be the one who can save her father.

"This is a girl who has no real memories of her father, so we'll be able to see what Hayley has done, if anything, to keep her aware of her father, who he is, and what the truth is about her life," Plec stated. "We'll see a young girl and see where she is with her own abilities. We'll get to see father and daughter eventually reunited, two strangers coming together with so much in common. There's some really special moments between them," she added.
