Not sure if these thoughts are worth spoiler-ing, but will err on the side of caution.

Spoiler!

1. I concur with the thought that Helly R is posing as an innie - though I don't know why since all their conversations appear to be recorded. The other reason for her off-ness could be the romantic thing, and I think outie Helena was intrigued by that kiss as well.
2. I think Lumon has control over the outie as well as the innie. I guess both are classified as Lumon employees. The ability to get them all back to the severed floor by offering a pineapple gift basket points to switches in the outies that can be activated. Selvig asks if a pineapple was involved. When an employee is severed, the company has control over both entities. The theme of Evil Industry exerting mind control over the populace.
3. The Keir cult worship is creepy AF. It doesn't appear non Lumon employees are even aware of the cult the innies are immersed in. Perhaps it is a control tool for the severed who have a child-like emotional level - or a mechanism for full emotional control.
4. Rikken is a hoot.
