I dont think TWD will be duel run nor will any house be duel run
About AWIL, the maze was very very popular... It scored some of the highest ratings they every had for a house (It surpass TWD that yr). So I can see it coming back and hopefully we have some upgrades to the Wolfs.
Most Haunts do repeats to very popular mazes and dont change a thing in them... If AWIL does come I dont think its because something was dropped.. I think this was 100% a A&D move.
