At time 21:12, Ruth dances over to the door of her office and rubs her hands gleefully over the "RUTH DUNBAR" name plate on her door. As she takes her hands away, you can see that the letter were apparently just vinyl stick-ons and she has rubbed off a "U" so the name plate now reads "R TH DUNBAR". A few seconds later in a view of her door as she walks into her office, it says "RUTH DUNBAR" once again.
