In the first lot, it looks to me like they’re in Jefferson’s house (or wherever it is that Cora kept Jefferson).
YES, hats everywhere! Gonna have to check Hat Trick to see if the room he’s in matches up, or if this could be somewhere he went to live if Cora set him free at some point, (I think she has to have, if he was ever able to have the tea party with Alice). Just looking at these couple of pics, it seems more of an enclosed space than what we saw in Hat Trick.
