Plec also revealed that this episode is one of her favorites of the series so far.

"The next episode is actually really crazy. It's new for us, and it's something we've never done before," she said. "We go outside of the Quarter and we put Rebekah and Klaus into a trapped situation in a creepy, horrible, messed up sanitarium from back in the day, and Genevieve, working between the two of them, enacts her revenge. We'll learn why Genevieve's revenge is so specifically targeted towards Rebekah and what exactly she's going to do to make Rebekah suffer as much as possible."
