In Empty Places (2003), Kennedy had a cut across her nose and two more between her eyebrows in the last scene. In the first scene here, which takes place a few minutes later, the cuts are completely gone.
This takes up exactly where the previous one ( Empty Places (2003) ) left off. Anya now has curly hair, but she had straight hair at the end of Empty Places. However, hair colors and styles changing abruptly from one episode to the next have been a running gag on this show, starting with Seth Green's character Oz and continuing with Anya.
At 18:18, a shadow is seen moving in the hallway at the top of the stairs, but Faith and The First are alone for several minutes. Possibly DB Woodside waiting to enter the room later in the scene?
