, that is some excellent observation work you've done. I'd always assumed that the Briefing Lounge* (as USS Mariner
observed) struts were arranged as simple partitions for Goodkirk and Evilkirk to walk around. It never occurred to me to arrange them around the conduit-thing, but it's undoubtably what was done in the episode.
Many many thanks for the correction!
is what Kelso called it in the teaser - perhaps it's a multi-purpose room?
