Yeah, agreed on the board and I thought of that later. That she decided "uh, no, this isn't right."
Plus, from season 1, she warned Mark to "get away from them." She definitely knows some shit even beyond what's been revealed thus far.
As for location I've read that Erickson said that Severance is in a "here-ish" place and a vaguely "now-ish" time. It's definitely the US since we've had US legislators discussing laws relating to the procedure.
I almost forgot about the alternate Kier images given to Milchick. That was wild. So brazenly manipulative.
Also "The board would like you to know that I also received these and I enjoyed them."
LOL. The board would. But the silent interchange between her and Milchick was so fraught with meaning. I think she was telling him "Yeah, this is fucked up." ... but who knows!
But that scene reminded me of the podcast interview with Tramell, the Milchick actor, who before starting the show, or early on, asked Stiller and the producers if the Milchick character "knew he was black." That had to have influenced that part of the show.
