What about the possibility that freeing the DO caused a portal to the Underworld to be opened and instead of it dragging someone down there, it releases people to come to SB. That way they can bring back a lot of old characters but yet save money from building new sets. Then the arc is having them try to figure out how to close back the portal. And in one interview A said that 5b would be the people have things from their past come back and this would fit that literally.
