The whole “OMG Killustrator” started because some paintings in a manor setting were spotted.
More (small) details are starting to reveal themselves (like the potential language of the house), but still not enough to fully know what the house IS.
To ride the art metaphor, it’s like staring at a painting from inches away. You see the details, but can’t see the actual picture.
EDIT - it’s like how the “Christmas house” rumor started because there was some work being done on the AC for one of the tents.
