In the previous episode, when Willie and Julia come downstairs, they hear a woman (Josette's ghost) sobbing. In this episode, it is a completely different voice sobbing and sounds like a man.
At the beginning- they show the brick wall. However, it looks much different than what they showed in the previous show. The bricks are very sloppy put together and mortar appears damp and hurried applied.
During the closing credits, the basement is shown with about one third of the bricks at the top removed and Barnabas absent. Yet, there would have been no way to get a passed-out Barnabas out from the wall unless nearly all bricks were removed.
