First, Katherine definitely hasn't disappeared off of the face of the earth, but there seems to be one big thing in the way of her showing her face in town again. Julie divulges these teaser-y bits to Michael Ausiello, "That elusive vixen is still somehow lurking in the shadows, but keeping herself well hidden… Given Klaus’ continued presence in Mystic Falls, we shall see if we’ll be able to get her back into town.”
Given that Klaus's story arc is really big this season and that Elena's a vampire now, do you guys think it's even possible we'll see Katherine reappear in Season 4's back half? Do you even want to see Katherine back? Sound off in the comments below!
