Therefore, my new rule is that this project is set during a conjectural "Season 4"
, or "Year 4 of the 5 Year Mission"
, and that any differences from the late Season 3 sets we can justify by saying that "it got changed before the production of Season 4", for lack of a better way to say it.
This seems to be the best
solution to make myself and others happy.
That's a good idea to adapt that rule as it'll make it easier for you to determine what your final product will be.
As to those green artpieces on the wall they look like fabric framed with scalpels and cutting instruments. So absent of a close-up or the actual prop your guess will be just as good, IMO.
