Theory about S1 refinement

Spoiler warning.

We believe generally that the refinement process is some kind of fundamental processing of experience into the four categories. Up to this point, it's not entirely clear whether these specific refinements are limited to the individual.

We see Helly's first recognition of numbers, and then Burt and Dylan recognize it too. This suggests that these numbers are recognizable by all refiners.

Mark's freshman fluke is probably related to Gemma. We see him apologize to Ms Casey multiple times - I suspect this is because he is the reason she is here, enslaved effectively.

My theory is that the "revolving" may be the process of refining the minds of individuals such that they can transfer consciousness using the severance chip. But, the old person is gone, and the severance chip holds the consciousness of the fully refined.

I believe all of the psychological work happening on the severance floor is intended to keep the severed in touch with their emotional intuition.

This may also ultimately lead to the revolving of Kier himself? I don't know.
