Helena is awful in some ways, but I do feel quite sorry for her. Think how she was probably brought up, in the Lumon cult. And she has a strained relationship with her very weird old father - not close or affectionate, he called her a 'fetid moppet' (what!?) after Helly took over at the corporate event where she was supposed to be giving a speech extolling the virtues of severance, but Helly came out and told the audience that the innies were being tortured. That Helly took over and obviously what Helly said wasn't even Helena's fault. And she obviously had family and company pressure to go through the severance procedure herself.
She said to innie Mark when they slept together in the tent that she didn't like who she was on the outside and she felt ashamed. I think that's true, and because of her upbringing and position as an Eagen she's never been able to have a normal sexual or romantic relationship, innie Mark could even have been her first.
And to answer a pp yes I do think she fancies Mark, she made the choice to sleep with him on the outdoor teaming building exercise. Even though she thinks innies are not real people (she's very conflicted). So I think she had more than one motive for approaching Mark in the restaurant. 1.She (and the company) need to find out what outie Mark knows, and 2.She feels attracted to him and was trying to make a connection with 'outie' Mark.
Helly, who is a very appealing character, is what Helena would have been with a different upbringing.
It is a very strange alternative world they live in! I still can't fathom why people would willingly allow themselves to be 'severed'. Pretty sure it wouldn't actually work in reality, (thankfully!) but it's a very interesting concept. Probably a metaphor for something.
And the cult of Keir Eagen, a man born in the late 19th century, and all the sanctimonious language around it, so strange, in a world that is in many ways similar to our own . But then I suppose America is home to many strange cults. Scientology and you could also say Mormonism, etc. I am starting to think that every religion began as a cult, just some began thousands of years ago, and some in the 20th century....
This is my favourite show by far! I've just binge rewatched Season 1, so many things I didn't pick up on the first time around. It's worth the subscription to Apple TV on its own, imo.
