There's a lot of people that could cross over, and when we plan our crossovers, we like to think of the most clever way to integrate The Vampire Diaries mythology into The Originals mythology," Julie Plec shared. She further added that the presence of Tatia, who happens to be the Original doppelganger, will bring out once again Klaus and Elijah's side of struggling with being in love with one woman which is comparable to what happened with Stefan (Paul Wesley) and Damon (Ian Somerhalder) in "The Vampire Diaries."
