ENTERTAINMENT WEEKLY: You all made a few changes to the Salvatore House, right?

And it grew from there.

The second episode really sets the stage for the episodic mythology.

Obviously the monster-of-the-week format will bring in a lot of new creatures.

We havent realized that goal yet but that is absolutely what we want to do.

Will that exploration be through flashbacks?I wouldnt say flashbacks as a general rule.

For all of them, theres the question of: Howd they come to this school?

Its a great opportunity for story.

Legaciesairs Thursdays at 9 p.m.
