I honestly don't remember the sconces showing up again - but that would be something to keep a lookout for while watching the show. They must have shown up in some other set at some point. But the bookcases/window were first used and continued to be used as a wall in Collinwood's study. My thing was that I don't ever remember Willie's bedroom set ever being seen again - and to me that's odd because it's a better set than some of the other bedroom sets we'd already seen and would see down the road...
