There’s so much to look forward to on this season of The Vampire Diaries. Elena’s 18th birthday, bad Stefan, and soapy Damon. But when prompted for his outlook for the season, Joseph Morgan says he’s most excited to meet Klaus’ family. “We get a chance to go back and see the point where they became vampires and where the curse was placed on Klaus to suppress his hybrid nature, his hybrid side,” he told a roundtable. “It’ll be interesting when we introduce other originals who are possibly equally as powerful or have some sort of emotional hold over Klaus … to see what that brings out of him.”
