I was sort of agitated with outie Mark being so uninterested in finding out the truth about Lumon this episode. Like I get that after watching Graner get killed, he probably wanted to get away and stay away from it all and you could add that hearing that his innie came out and spilled the beans on being trapped and tormented, it would be understandable if he just wanted to quit for his own safety. But Scott wasn't playing Mark like he was afraid of getting too involved. He just seemed over it and exhausted. And then he gets suckered back in, not on the faint belief that maybe innie Mark meant that Gemma was still alive but just because he bought into Milchik's bullshit. It did kind of feel like they were writing/direction him to be jaded so that it would feel more dramatic when he had his confrontation with Cobel.
I mean that moment where Cobel unwillingly showed her cards and roused Mark's suspicions was so well done to begin with. She knows the danger of that happening but when confronted with the question about Gemma, some sense of moral decency or guilt trips her up and she takes too long to answer. That's so effective on its own, I don't know why they needed to write Mark more or less out of character to achieve the scene's purpose.
Interesting that they heavily implied that Helly is Helena on the severed floor but then they discuss that Mark would be getting "Helly R" and didn't show us whether she physically switched Severance states in the elevator, leaving it a bit open ended. I think it's more plausible that it's Helena but I'm wondering if they're going for misdirection for some reason.
Irving talking about getting a message to his innie to an unknown caller and then outie Burt watching him from a distance is the biggest head scratcher. Like we know outie Irving is investigating Lumon and maybe it's for this unnamed organization that Petey referred to but like, what's Burt's angle? How did outie Irving get a message to his Innie aside from the paint hallucinations? I really couldn't even begin to guess where they're going with that. If Irving is aligned with this shadow resistance organization, I can't fathom that Burt's in there with him if he's spying on him. Maybe it's a Cobel situation where he's still working for Lumon on the outside.
Interesting to see that Helena got chewed by her father. My guess right now is if she is down there as Helly long enough she'll decide on her own accord to undermine her family's corporation but that seems almost too obvious. I think it'd be more interesting if she was just the show's main villain the way we've seen her here.
Last, Cold Harbor. It's obvious that Lumon needs Mark specifically for the Cold Harbor project and it relates to Gemma. The four bins for the MDR data correlate to the "four tempers" of the human soul theorized by Kier and Mark confirmed that he saw and identified Gemma's dead body. I think that's a fair bit removed from "brain dead" but maybe it's possible she only looked dead? Maybe Lumon faked her death to use her as a test subject? In any case, my guess is Mark's cold harbor work is directly a project to try to somehow wire or rewire Gemma's consciousness or brain functioning or both. Cobel seemed really interested in seeing whether Mark and Ms. Casey could remember each other even slightly. In wellness, Mark sculpted a tree which is what Gemma allegedly hit with her car when she allegedly died. And Lumon *needs* Mark to do the MDR work on Gemma. There has to be something to that. Like only Mark could subconsciously understand the intricacies of Gemma's psyche and personality for whatever they're trying to do. Regardless of how f***ed up it is to make a presumed widower the catalyst of human experimentation on his believed dead spouse. Or maybe she's a clone and they're using Mark to try to restore her consciousness and personality. Maybe the goats are an example of goat cloning. I don't know. I feel like there's a lot of hints of what they're trying to do, but none of them are particularly strong.
Like I said, even more questions after getting a bunch of answers.
